Cities play a critical role in decarbonization efforts, which aim to reduce greenhouse gas and other emissions to net zero.

But they can’t do it alone. That’s why 40 mayors and governors in the C40 network, which exists to tackle the climate crisis, have called for City leaders multilateral development banks (MDBs) to provide essential support.

In an open letter to the presidents of 10 global and regional MDBs, the mayors asked them to help by:

1. Including urban climate action and finance in the bank’s corporate and climate strategies.

2. Integrating cities and urban climate action in the country and sector assistance strategies.

3. Developing specific urban climate action programmes providing: technical assistance for project preparation and implementation; scaled-up concessional MDB finance; and enhanced support for private finance mobilization.

Reinventing Cities, a global competition run by C40, showcases some of the efforts cities are taking to decarbonize – which could be replicated globally with greater financial backing.

Fifteen cities developing sustainable zero-carbon and resilient urban projects are featured this year – here’s an introduction to their wide-ranging green plans.

Cities need zero-carbon plans for the future

Sustainable and inclusive urban development is the core focus of the Global Future Council on the Future of Cities – a World Economic Forum initiative dedicated to helping cities become greener, more climate resilient and also more affordable.

Cities are responsible for more than 70 percent of global carbon dioxide emissions, the Forum says. And by 2050, they will also be home to 70 percent of the world’s population – with much of this expansion taking place in the developing world.

These factors make cities extremely vulnerable to the effects of climate change, and it’s therefore imperative that all urban areas drive climate innovation, adaptation, and resilience.
