City leaders from around the world are showcasing real solutions for climate action at the C40 World Mayors Summit in Rio de Janeiro ahead of COP30. The theme of the summit is "Mutirão in Motion: Cities Leading the Way to COP30" and highlights Brazil's tradition of community collaboration to build solutions. Initiatives such as the Global Methane Hub and the Urban Planning Accelerator are being launched to support cities in cutting methane emissions and integrating climate and equity into city master plans. Mayors are calling for increased funding for urban climate finance and are pushing for the 'Baku-to-Belém Roadmap to $1.3 trillion' to mobilize public and private investment in cities, states, and regions, especially in the Global South. Investment in electric bus fleets in Brazil, Chile, Colombia, and Mexico has surged to US$4.3 billion, with a partnership aiming to drive port decarbonization through a $1 billion Global Port Sustainability-Linked Loan initiative. Mayor Sadiq Khan emphasizes the importance of cities in addressing climate change and building a sustainable future, while Mayor Eduardo Paes highlights the role of C40 cities in reducing emissions and creating green jobs. Mark Watts, Executive Director of C40, discusses China's "irreversible" green transition and growing global ambition, with efforts in transitioning to a more sustainable economy seen as a positive development in the fight against climate change, influencing other nations to follow suit. This shift towards sustainability is crucial in addressing the climate crisis and creating a more environmentally friendly future.

We can have growth while fighting climate change
Hannah Ritchie, a data scientist at the University of Oxford, offers encouraging answers to climate questions in her book "Clearing the Air." She believes the world is decarbonizing faster than most realize, with the real bottleneck being belief in progress. Ritchie discusses the dueling climate narratives of denial vs. despair, individual choices vs. systemic change, and shifting politics of clean energy. She highlights objective trends like the collapse in costs of solar, wind, and batteries, and the increasing deployment of clean technologies. Ritchie's views on climate change shifted from doom to optimism as she observed long-term data and technological advancements. The section emphasizes the importance of making choices now that will benefit future generations in terms of climate change, stressing the need to use current resources and tools to create a safer, cleaner, and fairer world for future generations. The author sees the optimistic story of climate solutions as an opportunity that requires action and effort to become a reality.

Victoria fast-tracks approval of major solar battery hybrid project, and new big battery in Latrobe Valley
The Victoria government has approved two major renewable energy projects, including a large solar-battery hybrid and an expansion of an existing battery in the state's coal heartland. The Meadow Creek solar farm will combine a 332 MW solar facility with a 250 MW, 1,000 MWh battery, while the Tramway Roads battery will be a 300 MW, 1,200 MWh project owned by Eku Energy. These projects are part of Victoria's push towards reaching 95% renewables by 2035, with a focus on solar battery hybrids to address cost increases and planning issues facing wind energy projects. The Meadow Creek project has faced community concerns but has addressed issues such as fire risk, water management, and visual impact through consultations with stakeholders. Giles Parkinson, founder and editor-in-chief of Renew Economy and The Driven, provides the latest clean energy news through their free daily newsletter.
