Tokyo Governor Koike Yuriko is embarking on an official overseas tour to demonstrate Tokyo's commitment to addressing climate change and sustainable urban development at United Nations-led conferences. During her visit to Egypt, the UAE, and Azerbaijan, Governor Koike will participate in events such as the UN COP29 climate summit and the UN-Habitat World Urban Forum. She underlines the significance of decarbonization, emphasizing the diffusion of hydrogen energy and renewable energies as key solutions to combat global warming. Governor Koike's proactive approach includes promoting Tokyo's innovative measures, such as plans for a 'hydrogen exchange' to ensure a supply of zero-emission 'green hydrogen' and the mandatory installation of solar panels on new houses. The Tokyo Metropolitan Government's initiatives aim to accelerate actions toward decarbonization and strengthen city-to-city cooperation with Abu Dhabi. By highlighting the role of cities in fighting the climate crisis, Governor Koike advocates for global collaboration and knowledge sharing on disaster countermeasures, transportation, and climate change responses. The upcoming COP29 and World Urban Forum are expected to address crucial topics like financial commitments for climate action and urban governance, reflecting Tokyo's leadership in promoting sustainable development and hydrogen energy.
