Decarbonization Journey for Low-Income Families in Light Public Housing – Transformation to Low Energy Buildings Network

Project Description:

CLP Power Hong Kong is advancing decarbonization through targeted initiatives across public housing customers which account for 40% of residential customers base and primarily serves low-income families.

Traditionally, gas cooking has been widely adopted, reflecting legacy practices and limited awareness of low energy alternatives. With technological advancements, induction cooking now achieves thermal efficiency exceeding 90%, compared with below 60% for gas cooking. This translates into carbon emission reductions of at least 16% and energy savings of no less than 49.2%.

CLP is taking a proactive role in enabling low-income families to transition to safer, more energy-efficient and low energy cooking solutions, supporting both near-term affordability and long-term carbon reduction objectives for LOW ENERGY BUILDINGS.

Energy Saving

These initiatives with total 28,280 families¹, are projected to deliver annual reduction of carbon emission by 1,380,000 kg CO₂ and equivalent to ~60,000 trees planting for those 28,280 units of Public Housing in total. Total energy saving from switching from gas to electricity is 24.6 GWh, hence the energy saving resulting from switching from gas to electricity amounts to 12.3 GWh. equivalent to approximately USD $2,217.3K per year. (Details calculation please refer to Part I.I- 1 Verifiability)

In 2025, a total of 6,540 families² moved into All-Electric Light Public Housing. According to test reports conducted by City University of Hong Kong in 2020 and 2025, carbon reduction from electric cooking compared with gas cooking is at least 16%. As a result, the total annual carbon reduction arising from fuel switching from gas to electricity for these families is estimated at 20.5 TJ (or 5.69 GWh), equivalent to approximately 318,600 kg of CO₂ reduction, or the environmental benefit of planting about 13,900 trees. Furthermore, the energy saving resulting from switching from gas to electricity amounts to 2.84 GWh, equivalent to approximately USD $512.8K per year. (for detailed calculations, please refer to Part I.I-1 – Verifiability).

Yau Pok Road (2,100 units) + Choi Hing Road (2,300 units) + Tsing Fuk Lane (1,900 units) + Shun On Estate School (130 units) + Choi Yuen Estate School (130 units) = 6,540 units.

1. Decarbonization Journey

CLP supports and accelerates the Hong Kong Government’s Climate Action

Plan to achieve net-zero greenhouse gas emissions by 2050.

By 2035, the electricity saving in residential buildings should be around 10- 15%. Subsequently, further reduction of 20-30% is planned. Being residential customers, it is hard for them to embrace the decarbonization roadmap. CLP has proactively supported based on the Ecosystem and Design Thinking Approach.

1.1 Hong Kong Government Strategies + Opportunities

- Carbon-Neutral Communities

Develop strategic growth areas into carbon-neutral communities

- Green Economy

Facilitate the development of green and sustainable finance, develop Hong Kong into a green financial hub in the region

- Public Engagement

Government to work together with different sectors to promote low energy lifestyle

1.2 Net-zero Electricity + Energy Saving and Green Families

Hong Kong Climate Action Plan clearly set the strategic directions for stakeholders including CLP to implement. CLP supports all customer segments for demand side energy management. Residential families, which account for about 30% total usage in Hong Kong, are crucial to develop the engagement and education plan for the journey.

2. Why Public Housing Matters: Decarbonization Must Be Inclusive

Around 40% of CLP’s residential customers live in public housing, serving primarily low-income families. Historically, cooking in public housing has relied heavily on gas, driven by legacy infrastructure, ingrained habits, etc. Gas combustion inevitably produces carbon dioxide, making decarbonization both technically and financially challenging for these families. Overall energy consumption including gas and electricity is about 29% in residential sector, as shown below.

In CLP’s decarbonization roadmap, this represents not merely an awareness gap, but an equity and affordability challenge. Low-income families are more sensitive to upfront costs and monthly energy expenses. A successful transition must therefore be practical, affordable, and aligned with everyday needs. CLP took a proactive role in studying the pain points, impacts and identifying feasible, low-cost solutions tailored to this group using design thinking approach.

Electric cooking in public housing sector is only 42% while in the private sector it is 59%, as per figure below. Most public housing families are not aware of the benefits of electric cooking, in particular induction cooking, which can achieve lower carbon emissions now and carbon neutral by 2050.

Hong Kong Energy End-use Data 2025 –

For decades, CLP has actively educated public housing households on using low energy fuels and equipment like induction cookers. The electric cooking market penetration in Hong Kong is increasing from 31% to 42% from 2013 to 2023. The increase demonstrates that the market response positively that the customers are graduating switching to electric cooking, mostly using induction cookers. Nevertheless, public housing families are more conscious about equipment costs and sometimes do not fully understand the benefits of electric cooking. Hence, the penetration rate is not as high as private market of 59%.

A Practical Solution: Lower-Carbon Cooking that Also Reduces Bills by Induction Cooking

CLP focused on solutions that deliver both carbon reduction and families cost savings. According to the Electrical & Mechanical Services Department (EMSD) energy efficiency certification¹, modern induction cookers can achieve efficiencies of 81%–91% (average 87%), compared with 48% - 72% (average 63%) for gas cookers. This performance advantage translates directly into lower energy consumption and reduced carbon emissions.

For low-income families, the key question is not whether decarbonization is desirable, but how it can be achieved without increasing costs. Induction cooking is the right solution and provides a pathway to address both concerns simultaneously.

Executive Summary of City University of Hong Kong test report in 2025

In this test results conducted in April 2025 by City University of Hong Kong, it showed that the carbon emission of induction cooking is from 16% to 23% lower than gas, with reduction of energy saving cost by 32.3%-38.3%. The results are like another test report conducted in December 2020 (Refer to ii).

Executive Summary of City University of Hong Kong test report in 2020

In this test results conducted in December 2020 by City University of Hong Kong, it showed that the carbon emission of induction cooking is from 20% lower than gas, with reduction of energy saving cost by 52%.

Design Thinking Approach: Understanding Real Needs

CLP adopted a Design Thinking approach to identify customer pain points and reframed the challenge as:

“How might we help cost-conscious families shift from traditional cooking methods to efficient All-Electric cooking, so they can reduce cooking costs and carbon emissions while preserving taste and cooking quality?”

This framing ensured solutions remained user centric, practical, and culturally appropriate.

5. Residential Market Ecosystem: From Promoting to Enabling Adoption

Rather than positioning decarbonization as a burden, CLP made use of Ecosystem to develop the market. It was shifted from awareness-based promotion to active enablement. CLP supports both short- and long-term decarbonization journeys by reducing adoption barriers related to cost, access, and confidence. Through Ecosystem business partners’ support, CLP enables low-income families to experience low energy cooking firsthand.

6. Scaling Impact through an Ecosystem Approach

CLP established an All-Electric Home Ecosystem involving consultants, equipment suppliers, and policy stakeholders. This collaborative approach supports market development across both public and private housing. For Light Public Housing projects using Modular Integrated Construction (MIC), electrification enables safer, faster construction, low energy options and ultimately carbon neutral by 2050.

These initiatives with total 28,280 families², are projected to deliver annual reduction of carbon emission by 1,380,000 kg CO₂ and equivalent to ~60,000 trees planting for those 28,280 units of Public Housing in total. Total energy saving from switching from gas to electricity is 24.6 GWh, hence the energy saving resulting from switching from gas to electricity amounts to 12.3 GWh. equivalent to approximately USD $2,217.3K per year. (Details calculation please refer to Part I.I- 1 Verifiability)

- The HKSAR Government’s Light Public Housing (LPH) policy aims to build ~30,000 modular units by 2027/28 to bridge the short-term public housing gap. To speed up, Modular Integrated Construction is adopted. Among 30,000 flats, 28,280 flats are in CLP supply areas.

- CLP provide support for all electric home design and implementation so that the construction time is shortened further.

A. Innovativeness

A. I Q: Is the innovative concept come from the project itself or other existing programs?

Ans:

The innovative concept is not entirely new in principle, but it is innovative in its application, scale, and system integration within the public housing context.

Low energy living through full electrification has been adopted in private residential developments for many years. However, its penetration in public housing has historically been low, mainly due to cost considerations, construction constraints, and tight project timelines. Recognizing this gap, CLP proactively adapted and extended proven electrification concepts into a network-ready, low energy building solution for public housing, commencing in 2024.

In alignment with the Housing Bureau’s policy direction, CLP supported the electrification of Light Public Housing (LPH) by designing an All-Electric building network that integrates energy-efficient appliances, electrical infrastructure readiness, and demand-responsive design. This approach enables Low Energy Buildings to operate with lower energy intensity, enhanced safety, and future compatibility with smart energy management and renewable integration.

The LPH developments demonstrate that full electrification at scale can be delivered smoothly, reliably, and on schedule, while forming a replicable low energy buildings network model for future public housing projects. Residents benefit from a modern, safe, and comfortable living environment, while the building network contributes directly to carbon reduction, operational efficiency, and long-term sustainability.

The Light Public Housing project at Yau Pok Road is the first successful implementation of this concept. Completed in late 2024 to early 2025, the project accommodates over 2,000 families in an All-Electric residential environment, serving as a practical demonstration of how smart building principles and low energy networks can be effectively deployed in public housing to support low energy living and community well-being.

A. II Q: How does the innovative policy design encourages financial support and public- private partnership?

Ans:

The innovative policy design adopts a Design Thinking approach to align social needs, technical feasibility, and financial sustainability, thereby encouraging both public-sector support and effective public-private collaboration.

Through early engagement with public housing stakeholders, key resident pain points were identified, including insufficient electrical capacity to support modern living needs such as electric cooking, high-power water heating, and contemporary household appliances. These insights informed the development of an All-Electric, Low Energy Building solution that addresses both residents’ well-being and long-term energy efficiency objectives.

From CLP’s operational experience, electrified homes deliver tangible and measurable social value, strengthening the case for policy and financial support. Electric cooking improves indoor air quality and eliminates risks associated with gas leakage and combustion. Instantaneous electric water heating provides a safer, more reliable hot water supply, enhancing comfort, hygiene, and daily living standards. In addition, modern electric appliances are increasingly energy-efficient, helping households manage energy consumption and operating costs more effectively. As Hong Kong’s electricity generation mix continues to decarbonize, these benefits compound over time, allowing residents to share directly in the Low Energy Building transition.

To translate policy intent into delivery, CLP provided professional advisory support across the full project lifecycle, including planning, design optimization, construction coordination, metering provisions, and smart meter installation. This end-to-end involvement enabled the formation of a practical and trust-based public-private partnership, reducing implementation risks and avoiding cost escalation or program delays.

By integrating technical expertise with public housing policy objectives, the collaboration enabled efficient capital deployment, minimized retrofit requirements, and enhanced long-term operational performance of the building network. The resulting partnership model demonstrates how innovative policy design, when combined with industry capability, can unlock financial support, accelerate adoption of smart Low Energy Buildings, and create a scalable framework for future public housing developments..

A. III Q: How does the innovative concept catch the trend of future development?

Ans:

The innovative concept aligns with future development trends by supporting the transition to Low Energy, fully electrified buildings that improve performance over time.

CLP’s decarbonisation roadmap commits to carbon neutrality by 2050, with clear interim milestones. By enabling full electrification in buildings today, the project establishes a low energy foundation that will progressively reduce carbon emissions as Hong Kong’s electricity supply continues to decarbonise.

From a low energy building perspective, electrification eliminates on-site fossil fuel use, improves energy efficiency through modern electric appliances, and supports smart metering and energy management. This allows buildings to operate with lower energy intensity while remaining compatible with future renewable energy and smart grid integration.

As a result, today’s low energy living environment is future-proofed to evolve into carbon neutral, Low Energy Building, making the concept scalable and aligned with long-term smart building and sustainability goals.

B. Inspiration

B I Q: Whether the idea can inspire later/subsequent cases?

Ans:

Yes, the idea is highly replicable and has already demonstrated its potential to inspire subsequent cases.

Following the successful implementation of the first All-Electric Home at Yau Pok Road Light Public Housing (LPH), the electrification and Low Energy Building concept is being scaled up across upcoming LPH projects. In total, around 30,000 flats will be delivered, benefiting approximately 60,000 residents with access to low energy, All-Electric living environments.

Beyond building design, the initiative also extends to behavioral and community support. The Electric Appliance Library, first launched at Yau Pok Road, enables low-income families to access energy-efficient electric appliances, supporting low energy and low energy living without additional financial burden. This model will be replicated in the second and third LPH developments, reinforcing a network-based approach to energy efficiency.

Together, the scalable electrification model and supporting appliance programmers form a practical, repeatable framework for future public housing projects, demonstrating how low energy building concepts can be systematically expanded to create broader social, environmental, and energy benefits.

B II Q: What domain has been enlightened by this policy?

Ans:

The policy primarily enlightens the social inclusion and low energy living domain,particularly for low-income households.

For low-income families, the key challenge is not whether decarbonization is desirable, but how it can be achieved without increasing daily living costs. The policy reframes this challenge by promoting efficient All-Electric solutions, such as induction cooking, which simultaneously reduce energy consumption, enhance safety, and maintain cooking quality.

As an experienced energy utility, CLP leverages its expertise in energy efficiency and Low Energy Building, supported by a clear corporate roadmap towards carbon neutrality. This strategic direction is translated into action by the Customer Sales and Success teams, ensuring that sustainability initiatives are inclusive of all customer segments, including those with limited technical knowledge or financial flexibility.

By adopting a Design Thinking approach, the policy shifts from technology-led deployment to people-centric solutions, addressing real household pain points. The guiding question becomes:

“How might we help cost-conscious families transition from traditional cooking methods to efficient All-Electric cooking, enabling them to reduce energy costs and carbon emissions while preserving taste and cooking quality?”

Through this approach, the policy advances a Low Energy Building ecosystem that is equitable, practical, and scalable, demonstrating how smart building strategies can support both environmental goals and social well-being.

C. Clearness

C I Q: Is there any open and transparent channel of public communication?

Ans:

Yes. The promotion of All-Electric cooking is embedded into the customer engagement journey for all residential customers, particularly at the point of moving into a new flat, ensuring early adoption of low energy living practices.

For public housing families, a dedicated promotion team supports the transition to low energy cooking through targeted outreach and seasonal promotion offers, reducing financial barriers while encouraging the use of energy-efficient electric appliances.

In addition, CLP organizes at least one public education and promotion event each year to raise awareness of the safety, energy-efficiency, and low energy benefits of electric cooking. Together, these initiatives reinforce behavioral change and support the broader adoption of low energy building solutions across different customer segments.

C II Q: Is there any difference between this policy and other similar policies?

Ans:

Yes. This electrification for LPH policy differs from other similar policies primarily in its methodology and level of quantification.

Unlike policies that rely mainly on qualitative commitments or generic benchmarks, this policy adopts a data-driven approach based on officially published market share data and standardized carbon emission factors issued by recognized authorities and utilities. The use of transparent, verifiable inputs enables a consistent and reproducible calculation of energy savings and carbon emission reductions.

As a result, the policy provides a higher degree of technical rigor, traceability, and comparability when assessing the effectiveness of fuel-switching measures.

D. Practicability

D I Q: Has any effective measures for moving ahead been made?

Ans:

Yes. An effective forward-looking mitigation measure has been implemented through the systematic substitution of gas-fired energy use with electrically powered systems. The resulting energy savings are quantified by applying the respective market penetration ratios of gas and electricity as published by the Electrical and Mechanical Services Department (EMSD) of the Hong Kong Government. Carbon emission reductions are calculated using officially published emission factors from the gas utility and benchmarked against CLP Power’s grid emission factors. By applying these standardized emission coefficients to the adjusted energy consumption baseline, the net carbon emission savings attributable to the fuel-switching measure are robustly derived.

D II Q: Is there any numerical goal for reference?

Ans:

The project aligns with Hong Kong’s Climate Action Plan 2050, which targets a 20%– 30% reduction in residential energy consumption by 2050 and a 50% reduction in overall carbon emissions by 2035. By achieving up to 50% energy savings and at least 16% carbon reduction through all-electric design, the project significantly exceeds prevailing residential benchmarks while delivering immediate social and environmental benefits.

E. Replicability

E I Q: Could the ideas, methods or techniques be applied internationally?

Ans:

Yes. The ideas, methods, and techniques are globally applicable and closely aligned with the United Nations Sustainable Development Goals (SDGs). Low-income households worldwide face common challenges in accessing energy solutions that are affordable, reliable, and low energy. This approach directly advances SDG 7 (Affordable and Clean Energy) by enabling informed fuel-switching decisions, while also contributing to SDG 10 (Reduced Inequalities) by alleviating energy cost burdens on vulnerable communities, SDG 12 (Responsible Consumption and Production) through improved energy literacy, and SDG 13 (Climate Action) by supporting measurable carbon emission reductions.

The international relevance of this approach is further reinforced by the leadership demonstrated by major utilities such as CLP, who’s clean-energy initiatives have been recognised as contributing to the advancement of SDG 7, which CLP achievements were recognized by SDG 7 award in 2025. This underscores the scalability and policy relevance of education-driven fuel-switching strategies in supporting low energy and net-zero living across different regions and socioeconomic contexts.

F. Cost-effectiveness

F I Q: Will it be cost-effective to implement?

Ans:

Yes. The initiative is cost-effective when implemented within the context of Light Public Housing for low-income families. LPH projects adopt standardized, modular construction and simple building designs, which already minimize capital and lifecycle costs. Integrating energy education and fuel-switching awareness within these developments requires relatively low incremental investment, as it focuses on behavioural change and informed energy choices rather than major infrastructure upgrades.

For low-income households, energy costs represent a significant proportion of monthly expenditure. By enabling residents to identify more cost-effective and lower-carbon energy options, the initiative delivers direct and recurring savings on utility bills, thereby improving household affordability and energy security. At the system level, reduced energy demand and lower carbon emissions generate broader social and environmental benefits, enhancing the overall cost-benefit performance of the Light Public Housing programme.

As a result, the initiative achieves high cost-effectiveness by leveraging existing housing delivery mechanisms, minimizing upfront costs, and delivering sustained financial and environmental returns for both residents and the community..

F II Q: Is there any measurable reduction of emission or energy use? Please describe the measurement method.

Ans:

Yes. A measurable reduction in carbon emissions and energy use has been demonstrated. The assessment is based on comparative performance testing of induction cooking versus conventional gas cooking. According to a test report conducted by the City University of Hong Kong, induction cooking exhibits significantly higher energy conversion efficiency. Using equivalent cooking output as the functional unit, the study found that the carbon emissions associated with cooking induction are approximately at least 16% lower than those of gas cooking and saves energy costs by at least 32%.

The measurement method adopts a life-cycle-based emission factor approach, where energy consumption during cooking is measured and multiplied by the respective carbon emission factors for electricity and town gas. By normalizing results against identical cooking demand, the methodology enables a transparent and reproducible comparison of emission intensity between the two cooking technologies.

According to the test results by the City University of Hong Kong in 2025, CO₂ emissions were reduced by 16% to 23% when cooking with an electric induction stove. In addition, energy consumption decreased by 32% to 38% compared with a gas stove. Energy consumption decreased by 49.2% to 53.7% compared with a gas stove.
According to the test results by the City University of Hong Kong in Dec2020, CO₂ emissions were reduced by 20% when cooking with an electric induction stove. In addition, energy consumption decreased by 52% compared with a gas stove.

As a result, the percentages used in this award programmer submission for calculating carbon emissions and energy costs adopted prudent approach. Only the lowest values among the above test reports—16% (range 16%-23%) for carbon emissions, 32% (range 32%-52%) for energy costs and 49.2% (range 49.2%-53.2%) for energy consumption saving are used for calculation.

G. Consistency

G I Q: Are adopted measures consistent with energy policy and strategy?

Ans:

Yes. The adopted measures are fully consistent with the Hong Kong Climate Action Plan 2050 (CAP 2050). In particular, the measures support CAP 2050’s strategic direction to reduce carbon emissions through enhanced energy efficiency and the electrification of end-use activities.

By promoting the transition from gas-based to high-efficiency electric technologies, the measures align with the Government’s long-term decarbonization pathway and its objective of achieving carbon neutrality by 2050, as outlined in the CAP 2050 framework.

G II Q: Is there any long-term measure or implementing organization for this project?

Ans:

Yes. The project is supported by a clear long-term strategy and a committed implementing organization. CLP has established its Climate Vision 2050, which aligns with and supports the Government’s Hong Kong Climate Action Plan 2050. Progress and performance are transparently reported through CLP’s Annual Sustainability Reports, which track decarbonization efforts, energy transition initiatives, and measurable outcomes over time. CLP’s sustainability performance has also been independently recognized by reputable international ratings and award bodies, including S&P Global, HKICPA Awards, and Australasian Reporting Awards, among others.

In addition, CLP has confirmed its long-term commitment to supporting Light Public Housing (LPH) developments through electrification solutions. This includes end-to-end support covering system design, planning, construction coordination, and energization, enabling low energy living configurations for residents. Under the current programmer, all 30,000 Light Public Housing units are planned to be commissioned by Q1 2027, ensuring sustained implementation and long-term impact of the project

H. Completeness

H I Q: Is the achievement scale measurable?

Ans:

Yes. The achievement scale is clearly measurable. In 2025, approximately 21,000 public housing units were commissioned, of which around 31% were Light Public Housing units. These Light Public Housing units were fully equipped with electric-only cooking facilities, enabling a direct and quantifiable shift away from gas usage. This large-scale electrification has resulted in significant and measurable carbon emission reductions.

The scale of implementation also represents a record-high level of delivery in the history of public housing development, demonstrating both the effectiveness and the scalability of the initiative..

H II Q: Will it make a considerable success in project goals?

Ans:

Yes. The project has achieved considerable success in meeting its stated goals. This initiative represents the first full All-Electric design adopted in the history of public housing. From initial design through construction to energisation, the first Light Public Housing (LPH) project located in Yuen Long was completed and commissioned in less than two years, demonstrating a significant acceleration compared with traditional public housing delivery timelines.

The adoption of modular integrated construction (MiC) played a critical role in this success. Most electrical wiring, fittings, and accessories were pre-installed off-site, substantially reducing on-site electrical works, construction risks, and programme uncertainty. As a result, electrical installation activities on site were minimised and more predictable.

CLP provided timely and coordinated support for meter installation and energisation, completing electricity supply arrangements for approximately 2,000 units within a matter of weeks. This level of efficiency was made possible through close coordination, early planning, and effective communication among all stakeholders, including government departments, contractors, and utility teams.

Following commissioning, tenant intake was carried out progressively. To ensure a smooth transition to All-Electric living, CLP implemented a comprehensive post-occupation engagement programme, including safety seminars, energy-saving talks, the introduction of Hong Kong’s first electric appliance lending library, cooking demonstrations and competitions, community fun days, and celebratory events. These initiatives enhanced residents’ understanding, confidence, and acceptance of electric living solutions.

The overall project outcomes and community engagement efforts were positively received, and formal appreciation was received from the Housing Bureau, affirming the project’s effectiveness, innovation, and social impact.

I. Verifiability

I I Q: Is there any data presented to support the project?

Ans:

Yes. According to the Hong Kong Energy End-use Data 2025 published by the Hong Kong Government, the proportion of households using electricity for cooking is 42%, while 58% use gas. The average consumption per flat for cooking is 1,500 kWh per year.

Based on these assumptions, we have calculated the forecasted energy consumption for newly built public housing lighting, as well as the projected consumption if households switch from gas to electricity. In addition, referencing the test report from the City University of Hong Kong, carbon emissions can be reduced by at least 16% when using electricity.

Refer to record from CLP website, a 5-meter-tall tree can absorb 23kg CO₂ per year.

J. Impact

J I Q: Will it make a significant change in the field of energy efficiency and energy saving?

Ans:

Yes. The project is expected to make a significant and meaningful change in the field of energy efficiency and energy saving. By adopting an All-Electric design in Light Public Housing at scale, the initiative moves beyond incremental efficiency improvements and introduces a structural shift in end-use energy consumption, particularly in cooking, which is a major daily energy use for households.

The deployment of high-efficiency electric appliances, combined with modular construction and pre-installed electrical systems, improves overall energy performance while reducing construction waste, installation errors, and lifecycle energy losses. Compared with traditional gas-based systems, electric cooking solutions—such as induction technology—deliver higher energy conversion efficiency and lower carbon intensity for the same level of service.

Importantly, the project also integrates behavioral and educational measures, including safety training, energy-saving guidance, and hands-on community engagement. This ensures that energy efficiency gains are not only technical but also sustained through informed user behavior, amplifying long-term energy savings.

At a sector level, the successful implementation of this first largescale All-Electric public housing model establishes a new benchmark for future public housing developments and demonstrates a replicable pathway for achieving higher energy efficiency, lower emissions, and improved affordability simultaneously. As such, the project contributes materially to advancing best practices in energy efficiency and demand-side energy management.

K. Women Empowerment

K I Q: Will the project empower women through education, training, skill development, or access to capital and markets?

Ans:

Yes. The project supports women’s empowerment through education and skill development by providing technical seminars on energy efficiency, enhancing participants’ knowledge and professional capabilities in sustainable building and operations. The seminar speakers and organizers are women over 50%.

L. Equality

L I Q: Will the project make a positive impact on gender equality or benefit both women and men?

Ans:

Yes. The project makes a positive contribution to gender equality and benefits both women and men. Project-related community engagement and educational activities organised by CLP were designed to be inclusive and accessible, with active participation from both female and male residents. These events—such as safety briefings, energy-saving workshops, cooking demonstrations, and community activities— encouraged shared learning and joint decision-making within households.

By promoting equal access to information, skills, and resources related to All-Electric living, the project supports balanced participation across genders and avoids reinforcing traditional gender roles in household energy use. As a result, both women and men are empowered to benefit equally from improved safety, energy efficiency, and cost savings, contributing to a more inclusive and equitable community environment.

M. Just

M I Q: Will the project deliver domestically defined equitable benefits, and pursue positive environmental, social, and economic outcomes?

Ans:

Yes. The project delivers clearly defined equitable benefits while advancing positive environmental, social, and economic outcomes.

Social & Stakeholder Benefits

The initiative provided tangible benefits to local communities, particularly Light Public Housing (LPH) families, by improving household safety, reducing financial pressure, and enabling greener daily living. Participating families experienced safer cooking environments and lower energy burdens. NGOs strengthened their engagement with beneficiaries and expanded their service impact, while government agencies reinforced support for LPH initiatives and advanced low energy transition objectives. CLP further enhanced its ESG reputation and demonstrated leadership in community-driven sustainability.

Economic Outcomes

The project generated significant economic value through heightened public awareness and strong media engagement, achieving over US$1 million in earned media value across major television, radio, print, and more than thirty

online news platforms. Continued exposure was supported by government commentary and social media amplification.

For beneficiaries, 1,000 families gained access to safe, flameless, energy-efficient induction cooking solutions, reporting improved household safety, faster meal preparation, and 32% reduction in cooking-related energy burden. Sponsorships and kind contributions delivered over US$50,000 in cost savings, contributing to a strong return on investment.

Environmental & Market Impact

Public awareness of induction cooking benefits—covering safety, cost savings, and emissions reduction—rose significantly. The project helped position induction cooking as a preferred solution for public housing and supported broader momentum toward All- Electric homes in Hong Kong.

Scalability & Long-term Outcomes

The initiative established a scalable, partnership-based delivery model with potential for district-level expansion. It also created pathways for wider household electrification programs and laid a strong foundation for future low energy living initiatives within the public housing ecosystem.

N. Inclusiveness

N I Q: Will the project create resilient firms, institutions, and communities, and provide support for decent work and workforce development?

Ans:

This project has enabled over 28,280 low-income households to benefit from the use of more sustainable energy, achieving at least a 16% reduction in carbon emissions, a 32% reduction in energy costs for basic living needs, and up to 50% energy savings. In addition, the project delivers immediate improvements in living standards and social stability for residents, while serving as an effective transitional solution as long-term housing supply is being developed. Overall, the project has contributed to the creation of resilient communities and provided meaningful support for workforce development.
