Mayors Unite for Coordinated Climate Action Before UN Conference in Brazil

In Rio de Janeiro, 300 mayors gathered to pledge coordinated climate action ahead of the UN conference in Brazil. Organised by C40, the summit highlights local leaders' crucial role in addressing climate change and supporting their communities.

A gathering of 300 mayors took place in Rio de Janeiro, aiming to tackle climate change and its effects on urban areas. This meeting, organised by C40, a network of city leaders, focused on collaborative climate action. The event occurred just before the UN climate conference in Brazil. Selwyn Hart from the UN highlighted the crucial role of mayors in addressing climate challenges.

Mayors' Role in Climate Action

Ana Toni, Brazil's climate change chief, emphasised that achieving the Paris Agreement goals relies heavily on mayors. "It is you, mayors, who have to make very hard decisions in daily life, together with people," Toni stated. The Paris Agreement seeks to limit global temperature rise to 1.5 degrees Celsius above pre-industrial levels by reducing emissions from fossil fuels.

The summit also addressed criticism of the US withdrawal from the Paris Agreement. London Mayor Sadiq Khan remarked that while mayors have been proactive in climate efforts, some national leaders have lagged. "Now, it is an existential fight between the climate wreckers and climate defenders," Khan said, pointing out the US president's scepticism towards climate change.

US Cities' Commitment

Phoenix Mayor Kate Gallego shared positive news about US cities' dedication to climate initiatives. She noted that 50 American cities are committed to ambitious climate action despite national setbacks. Gallego discussed Phoenix's extreme heat challenges and plans to mitigate them through tree planting and cool-surface technology.

Extreme heat has become a significant concern globally, affecting health and economies. Scientists report that human-induced climate change caused an extra month of extreme heat for half the world's population from May 2024 to May 2025. This heat led to illnesses, deaths, and economic strain, according to World Weather Attribution and other organisations.

Global Coalition for Cooler Cities

On Monday, C40 mayors launched the Cool Cities Accelerator, a coalition of 33 cities aiming to prepare for hotter climates. Cities like Austin, Boston, Buenos Aires, and Nairobi will collaborate on emergency measures such as early warning systems and cooling projects. The initiative receives support from several foundations and aims to improve urban infrastructure within five years.

Yvonne Aki-Sawyerr highlighted the severe impact of extreme heat as a leading weather-related disaster causing nearly 489,000 deaths annually. She warned of potential economic losses reaching $2.4 trillion by 2030 due to unsafe outdoor working conditions in sectors like construction and agriculture.

Emilia Carrera from the Rockefeller Foundation explained that cities will report progress every two years on measures like cooling centres and updated building codes. "Mayors see these challenges very closely. They have a fresher perspective and an ability to respond more quickly," Carrera noted.

The summit underscored the importance of local leadership in combating climate change as cities face increasing temperatures and their consequences.
