ABOUT CLIMATE TRANSITION 2100 CIC
ABOUT CLIMATE TRANSITION 2100 CIC
Climate Transition 2100 CIC (CT2100) is a UK-registered, community-based climate solution hub dedicated to developing inclusive, tech-enabled and community-supported responses to local climate challenges. CT2100 works in partnership with groups disproportionately affected by climate impacts, including people with disabilities, elderly, ethnic minority communities and households facing energy poverty, to co-design practical tools and approaches that meet real day-to-day needs.
Our work includes community projects, accessible climate-tech development, education and capacity building initiatives, consultancy services and policy-informed research. CT2100 connects everyday community experience with evidence-based, workable climate solutions that can be applied locally, nationally and internationally.
CT2100 was founded by a team of committed change-makers with deep experience in developing, scaling and promoting community-centred climate solutions. Inspired by decades of collective experience in humanitarian aid, security, and grassroots climate action, the founders recognised a crucial need: to bridge the gap between high-level climate policy and on-the-ground realities of vulnerable communities.
Our work is grounded in the conviction that effective climate solutions must be accessible, tech-enabled, and co-designed with the people they serve.
Climate Transition 2100 CIC purpose is clear:
Creating climate solutions that work for everyone.
A MESSAGE FROM CHAIRMAN
A MESSAGE FROM CHAIRMAN
As I look toward 2100, I see a world that has finally learned to place climate justice at the centre of its development pathway. This vision is not abstract for me; it is shaped by more than two decades of work alongside community leaders, students, activists, researchers, and policy pioneers across Asia and beyond. Climate Transition 2100 CIC is the continuation of this journey — and an expansion of it. It reflects my belief that a just, equitable and sustainable future is not only necessary, but achievable if we commit to collective action.
My path began in 2002 during the World Summit on Sustainable Development (WSSD) in Johannesburg, chaired by President Thabo Mbeki. Representing Oxfam International, I presented a collection of global voices calling for world leaders to deliver a sustainable future for all. Standing among advocates from across the globe, I realised how underrepresented youth voices from Asia were in these crucial conversations. That moment planted a seed: a commitment to empower young people and amplify voices often unheard in climate governance.
In 2007, this commitment led me to join the University of Hong Kong (HKU) as Director of Student Development at the Centre for Development and Resources for Students (CEDARS). My mission was to nurture global citizenship among students. I introduced four interconnected themes — climate justice, HIV/AIDS, poverty, and disability rights — as lenses through which young people could understand global challenges. Under the climate justice theme, I led youth delegations from Hong Kong to COP13 in Bali and COP15 in Copenhagen, and helped bring Professor Nicholas Stern to HKU during the 2008 financial crisis. His message of “green recovery” stayed with me, long before it became mainstream.
In 2008, together with like‑minded partners, we founded Carbon Care Asia (CCA) to introduce carbon reduction and carbon offset solutions to Hong Kong. CCA grew into one of the city’s leading ESG consultancies, and in 2022 its ESG services were acquired by Deloitte China. Following this transition, CCA evolved into Climate Finance Asia (CFA), shifting its focus to mobilising financial resources to accelerate climate mitigation across Asia. In 2023, I supported CFA’s successful application to join the Tokyo Metropolitan Government’s Green Finance Subsidy Scheme. Under my guidance, CFA has deepened its work on energy transition, publishing a Just Transition report for financial institutions, an analysis of coal‑fired power transition in Asia, and most recently, a report on the Carbon Border Adjustment Mechanism (CBAM) with the World Economic Forum.
My belief in climate justice also inspired me to establish CarbonCare InnoLab (CCIL) in 2014 to promote innovative community‑based climate solutions. I served as CEO from 2019 to 2024. Three CCIL achievements continue to make me proud:
1. The SolarCare Project
With support from the Hong Kong Jockey Club, we installed solar energy systems on NGO premises, reducing reliance on coal-generated electricity. Through Hong Kong’s Feed-in Tariff (FiT), SolarCare generated steady financial returns for our NGO partners and CCIL, while expanding public awareness of renewable energy.
2. Community Education through NGO Partnerships
Working with NGOs, we co-developed climate learning programmes for young people, elderly communities, and people with disabilities — ensuring climate action is accessible and inclusive.
3. The CATY Programme (Climate Advocacy Training for Youth)
A structured global climate leadership programme that trained over 20 young people every year since 2021 and offered them exposure to the COP process and international climate negotiations.
After retiring from full-time organisational roles in Hong Kong, I have chosen to relocate to the United Kingdom. I believe the UK provides a strong foundation for my continued contribution to global climate justice. Climate Transition 2100 CIC is both a continuation and a new beginning. It is built on everything I have learned — from global summits and university campuses to community dialogues and financial innovation.
I am also excited to be working again with Alissa and Rosita, trusted partners from my CCIL years, as we bring this new vision to life. Together, we aim to advance climate transition pathways that place justice at the core and ensure that no community is left behind.
Looking ahead to 2100, my hope is that future generations will inherit a world where climate justice is no longer an aspiration but a lived reality — one shaped by courage, inclusion, and the relentless belief that transformation is possible when we act together.
Best,
Chan-yau Chong

Dr. Alissa Tung
Chief Executive OfficerDr. Alissa Tung
Dr. Alissa Tung is a seasoned climate-social innovator and strategic leader with over a decade of experience in driving high-impact climate mitigation and adaptation initiatives. She specialises in bridging the gap between scientific insight and community-driven action, ensuring that the transition to a net-zero future is both technologically sound and socially equitable.
Alissa’s influence extends to the global stage, having served as a Board Member of the Climate Action Network (CAN), the world’s largest network of NGOs working to limit human-induced climate change. Her strategic oversight in this capacity, combined with her experience as an NGO Observer at UNFCCC COPs, positions her as a bridge between local grassroots climate action and international policy frameworks.
Alissa has a proven track record of managing complex, large-scale technical projects, including the development of 38 solar systems with a total system capacity of 3.4MWp and over 6,800 solar panels. She pioneered a first-of-its-kind business model in the region that transformed civil society organisations and schools into clean energy hubs. By strategically leveraging philanthropic funding and government Feed-in-Tariff (FiT) policies, she enabled non-profit organisations to generate sustainable revenue. This model redirects energy rebates back into social services and climate initiatives, creating a self-sustaining financial engine that addresses both climate change and social inequality. Her leadership extended to global professional networks through the launch of the Asia Solar Energy for Climate Change Conference (ASECCC), mobilising experts to accelerate the regional solar transition.
As a leading voice for Just Transition in Hong Kong, Alissa co-designed the award-winning Climate Community Dialogues. These systematic platforms empowered vulnerable groups, including residents of inadequate housing and persons with disabilities, to co-create climate resilience strategies. She transformed these ideas into concrete adaptation projects, enabling citizens to use peer knowledge to tackle climate-induced health and comfort issues, such as indoor overheating, humidity-driven mould, and rising energy cost.
Alissa initiated the Climate Advocacy Training for Youth (CATY), a transformative platform that empowers the next generation to visualise their power as climate leaders. CATY provides the structural training and platform for youth-led advocacy, enabling young citizens to drive the environmental issues they care about onto both local and global stage, including active participation at UNFCCC COPs.
Prior to her focused work in the climate sector, Alissa held a senior leadership role at HandsOn Hong Kong (part of the global Points of Light network). She bridge-built between grassroots community needs and the Corporate Social Responsibility objectives of over 25 multinational corporations (MNCs). This foundation in international volunteerism and multi-stakeholder management allowed her to merge global philanthropic standards with localised execution, a skill set that has enabled her to secure over USD 22M in funding from major institutional donors to sustain long-term social and climate initiatives.
At Climate Transition 2100, Alissa leverages her dual expertise in science-based transition strategies and scalable climate-social solutions to drive systemic change, ensuring that the roadmap to 2100 is built on both innovation and inclusivity.
