As COP28 enters its second week, C40 joins more than 800 signatories and counting from across business, finance, philanthropy, politics, academia, and civil society in calling on the COP28 President Dr Sultan Al Jaber and all parties at COP to negotiate a plan to keep 1.5°C in reach and secure a safe and healthy future for all.

Dear COP28 President Dr Sultan Al Jaber,

As we enter the final days of COP28, we are at a tipping point.

The world and its people need the strongest possible outcome to keep 1.5°C within reach. But delivering on this historic task requires us to act like a team.

The signals of transformation and opportunity across sectors and society are all around us. At the same time, the climate emergency is biting harder than ever. It’s up to us to seize this opportunity, because what is achieved in Dubai must mark a legacy moment that determines the fate of our future generations.

We – mayors, CEOs, governors, investors, Indigenous peoples, health professionals, young people, faith leaders, scientists, athletes and more – stand in courage and resolve with the COP28 President and all Parties in bringing us together behind a rapid response plan to the Global Stocktake.

To reach this positive tipping point, we know we need the following:

  • An orderly phase-out of all fossil fuels in a just and equitable way, in line with a 1.5°C trajectory, whilst ensuring the tripling of global renewable energy capacity by 2030 from 2022 levels and the doubling of energy efficiency.
  • The enabling environment to scale up and shift public and private finance, with developed countries taking the lead in action and support, putting a price on carbon and tripling investments for renewable energy.
  • The halt and reversal of deforestation and land degradation, as well as biodiversity and other ecosystem loss by 2030, ensuring resilient food systems and delivering a strong global goal on adaptation.

These outcomes must be supported by the implementation and ratcheting of Nationally Determined Contributions and National Adaptation Plans well before COP30 in 2025, which align with 1.5°C and incorporate multi-stakeholder efforts within them.

Later is too late.
