Shuichi Abe, Governor of Nagano Prefecture
We resonate with your commitment to confronting the climate crisis, and we, too, will not stop taking action as we work together to carve out a path toward the future.

Katsuhiro Akimoto, Mayor of the City of Sapporo
The City of Sapporo endorses the Japan Climate Action Summit 2025 Declaration, and will promote measures such as energy-saving strategies and the implementation of renewable energy suited for our cold, snowy climate to work toward the realization of a zero carbon society.

David Costa, Head of Sustainability Innovation Headquarters, NTT DATA Group Corporation
NTT DATA will lead by example, to disrupt industries for good, innovating services and solutions to regenerate our planet. We focus on our updated material issues such as climate change, circularity, and efficient water management, and are committed to Planet Positive initiatives. Regarding climate change, we aim to achieve Net-zero emissions by 2040 and contribute to the decarbonization of both our company and our supply chain.

Lorena Dellagiovanna, Senior Vice President and Executive Officer, Chief Sustainability Officer, CHRO, CDEIO, Hitachi, Ltd.
Long-term global efforts are essential in tackling growing environmental issues such as climate change. Under the group sustainability strategy “PLEDGES,” which defines our commitment, aspirations and targets for sustainability, as well as our Environmental Vision, Hitachi is leading the Green Transformation (GX) globally, with the aim of achieving net zero in its value chain by fiscal 2050.

Masanori Imai, Chairperson and Representative Director, Toda Corporation and Representative Director of the Japan Climate Leaders’ Partnership (JCLP)
I believe it is our responsibility to work together to leave a sustainable world for future generations. By reducing greenhouse gas emissions in our business operations and daily lives, and advancing initiatives such as floating offshore wind power and renewable energy, we are committed to building a bright and hopeful future.

Dan Ioschpe, Climate High-Level Champion for COP30
Leading the Transition to a Decarbonized Society” Declaration underscores how businesses, cities, states and regions turn ambition into action through scaling renewables, boosting energy efficiency, and driving deep supply-chain decarbonisation. With these actions already underway, the net-zero transition is both inevitable and within reach. However, in order to meet our 2030 goals, we need to utilise the power of collective action to accelerate and scale these efforts.

Sherry Madera, Chief Executive Officer, CDP
CDP stands with the Japan Climate Initiative in our shared commitment to tackling the climate crisis and securing a future where the 1.5°C limit is maintained and net zero is achieved. As the world’s leading environmental disclosure platform, CDP has been driving transparency and accountability for over 25 years. We believe that when data speaks, change follows. Through the world’s most comprehensive environmental data system, we empower companies, financial institutions, cities and governments to make informed decisions that align economic growth with the planetary boundaries. By turning disclosure into action and ambition into measurable progress, we help build an Earth-positive economy for generations to come.

María Mendiluce, CEO, We Mean Business Coalition
The strong pledge from businesses and other non-state actors in Japan is timely and inspiring. Despite geopolitical turbulence, the global clean energy transition is accelerating. Polling shows 96% of Japanese business leaders want Japan to move from fossil fuels to a renewables-based electricity system, and companies are decarbonizing because it makes business sense. Clear and predictable policies, coupled with aligned incentives to support the clean energy transition, will accelerate business investment, spur job creation and lower costs. We Mean Business Coalition stands ready to work with JCI and partners, supporting stronger economies and more resilient societies.

Richie Merzian, CEO, Clean Energy Investor Group
The transition to a decarbonized society presents a global business opportunity—and Japan, as a globally recognised business leader, is well positioned to help drive it forward. Australia’s ambition to host the UN Climate Conference next year, in partnership with its Pacific neighbours, is an effort to bring the whole world to the Pacific to work together on climate solutions. We are eager to partner with Japanese NSOs to seize the opportunities emerging from the energy transition.

Midori Miyazaki, President, Chiba University of Commerce
The Chiba University of Commerce, CUC, became the first university in Japan to
join the United Nations–led Race to Zero campaign in 2021. We are committed to
reducing greenhouse gas emissions by half by 2030 and achieving Net Zero by
2040. CUC has already achieved 100% renewable electricity.
We have long been dedicated to cultivating leaders with a strong sense of ethics
who can accurately perceive the needs of the changing times and address various
social issues. Together with local stakeholders, we will continue to take
proactive measures to tackle global climate change challenges.

Nobuhito Mori, Weather Attribution Center Japan
I sincerely hope that the seriousness of climate change will be widely recognized, and that people will rise to the challenge of addressing it.

Tetsuo Ohkawa, Representative Director and President, Ohkawa Printing Co, Ltd.
In pursuit of the Paris Agreement’s 1.5°C target, we continue to take action as a locally rooted printing company, striving to set an example for small and medium-sized enterprises.
The climate crisis is not a distant issue—it is a challenge we face right now, in this very moment. That is precisely why we reaffirm our commitment to corporate responsibility and resolutely express our determination to help build a sustainable society. We will move forward, step by step, in collaboration with like-minded partners who share our values and aspirations.

Takanori Okabe, Director, The Japan Agricultural News MIDORI GX Lab
Agriculture is one of the industries most visibly affected by climate change. Through food, these impacts reach your daily life as well. Support and stand with farmers who are taking action. We eat three times a day — and each meal is a chance for you to make a difference.

Mikako Suzuki, Corporate Officer in charge of ESG and Risk Management ESG Strategy Division, RICOH COMPANY, LTD.
Addressing the climate crisis can no longer be delayed. We are committed to intensifying our decarbonization efforts more than ever before.

Japan Climate Action Summit 2025 Declaration
Leading the Transition to a Decarbonized Society
— We Will Never Stop —

With less than five years remaining until 2030—a critical milestone for achieving the 1.5°C goal, the urgency of the climate crisis continues to intensify. Across many regions, extreme heat, typhoons, heavy rainfall, and flooding are occurring with increasing frequency.

While some parts of the world are witnessing setbacks in climate action, there is also a growing movement to confront these headwinds and steadily advance toward decarbonization.

In the United States, a coalition of non-state actors—including state governments and businesses—representing two-thirds of the population and 70% of GDP, remains resolutely committed to the transition to a decarbonized society. Europe continues to lead with progressive climate policies, and recent elections in Canada and Australia have reaffirmed the global momentum toward decarbonization, with climate-conscious administrations remaining in power. These developments underscore the irreversible trend of the global shift toward a decarbonized future.

The UN’s special report released in July this year, Seizing the Moment of Opportunity, offered hope to the world by highlighting that, in the ten years since the adoption of the Paris Agreement, renewable energy has expanded rapidly while generation costs have plummeted—marking a turning point in the transition away from fossil fuel dependence. Furthermore, the International Court of Justice (ICJ) issued an advisory opinion affirming that states have a legal obligation to take climate action, including the reduction of greenhouse gas emissions, thereby reinforcing international public opinion and encouraging national efforts.

As non-state actors in Japan participating in the Japan Climate Initiative (JCI), we must now reflect on the significance of our mission and determination to overcome the climate crisis, which allows no time to spare. It is imperative that we remain aligned with the global momentum toward decarbonization and continue to move forward in solidarity with our international peers.

On the 10th anniversary of the Paris Agreement and in the lead-up to COP30, JCI hereby declares its unwavering commitment to the challenge of decarbonization at the Japan Climate Action Summit 2025.

We encourage as many endorsements as possible for the attached declaration.
