CIDOB Opinion 612 highlights the pivotal role of cities in addressing the climate crisis, underscoring their significant economic impact and environmental footprint. With cities accounting for 2% of the Earth's surface yet housing 70% of global GDP and emitting 70% of greenhouse gases, their role in combating climate change is indispensable.
The European context demonstrates cities' dynamic approach to tackling climate issues. For instance, 64% of Eurocities members have pledged to achieve climate neutrality by 2050, and the Covenant of Mayors, an initiative launched in 2008, now comprises nearly 10,000 local governments across Europe, serving over 315 million inhabitants.
Urban solutions and innovations cover a broad spectrum, including sustainable mobility, energy-efficient construction, urban planning, green space creation, waste management, and the adoption of alternative energy sources. Projects like Barcelona's Low Emission Zone, Stockholm's emission reduction strategies in construction, and Rotterdam's electrification of urban buses exemplify these efforts.
However, cities face significant challenges in advancing climate goals without robust institutional and financial structures. The European Green Deal, a roadmap towards ecological transition, acknowledges cities' role but lacks clarity on specific measures for sustainable urban development. This implies a need for increased support and visibility for cities, recognizing their unique challenges and disparities across Europe.
CIDOB Opinion calls for cities to have a prominent role in the European Climate Pact, advocating for their participation in its design and implementation. The pact aims to facilitate a just and socially equitable transition, emphasizing the importance of the Covenant of Mayors as a platform for sharing knowledge and experiences. It stresses the necessity of clearer support mechanisms for European cities, highlighting the importance of accessible funding and tailored assistance to ensure their continued leadership in sustainable urban development.
