I’ve dedicated much of my working life to the science of climate change, sustainable development, adaptation to climate change, mitigation of climate change, and clean energy provision. With this experience I believe I can help the IPCC focus on the UN Sustainable Development Goals, Climate Justice, and a fair transition. Watch now my campaign’s official video subtitled in the 6 UN languages.

Vision for IPCC

“I want the IPCC to be the dynamic and inclusive “Voice of Climate”, providing all policymakers with the most solid and useful scientific information. I aspire to lead the IPCC in a collaborative and efficient way, serving its members full-time and contributing to the capacity development of the next generation of IPCC authors.” Jean-Pascal van Ypersele

Quote :

“The climate does not participate in the international climate negotiations. The IPCC needs to be the global voice of climate and climate sciences, and work in the most inclusive way ever to help improve the wellbeing of all inhabitants of our common home: the only liveable planet in the solar system.” Jean-Pascal van Ypersele


Quote 2015 :

“The debate has shifted from a scientific one 40 years ago to a very political one today, involving economic interests, geopolitics, different priorities given to environment or development, and a clash between short-term and long-term visions.” Jean-Pascal van-Ypersele (2015).
