Why set cities SBTs?

Imagine a world where cities thrive in harmony with nature. Where urban areas flourish with green spaces, clean air, and abundant biodiversity. Where cities not only meet the needs of their citizens but also protect the ecosystems that sustain us all. 

At the Science-Based Targets Network, we’re here to guide cities on a clear, actionable path to a net-zero and nature-positive future.

In addition to the Climate Guidance for Cities, SBTN is developing a framework for cities to set science-based targets for nature. Launched at COP28, this program focuses on creating nature-based targets specifically for cities. The first version of this guidance is expected to be available by spring 2025.

Is your city interested in taking targeted action on nature? Join our community of cities to stay updated on the progress and future events and get the opportunity to become a pioneer in piloting Nature Science-based targets for Cities.

Why Focus on Cities?

Cities are home to over half the world’s population, and by 2050, that number will rise to 68%, making cities the biggest drivers of environmental impact. By setting clear targets for climate and nature, cities become a powerful lever to create healthier communities, boost economies, and improve quality of life for their residents.

Need for a Universal Guidance

The Kunming-Montreal Global Biodiversity Framework sets a global goal to stop and reverse biodiversity loss by 2030. This goal, paired with the push for net-zero emissions, acts as a compass for local and national governments. However, cities face a lack of standardised guidance on how to translate the global objectives into meaningful and actionable targets to incorporate in their urban context. Applying existing frameworks to the specific contexts of cities can be challenging. Too many cities are having to invent their own approach. There is a need for global alignment on a legitimate approach that allows all cities to assess their impact areas and set feasible targets.

Cities within Earth boundaries

Setting Science-Based Targets helps cities align with earth boundaries, ensuring they protect nature and meet climate goals at the same time. These targets provide a clear roadmap for cities to operate within the planet’s safe limits while ensuring justice and equity, as defined by the Safe and Just Earth System Boundaries set by the Earth Commission.
