In the refrigeration industry, the use of refrigerants is imperative - that's a fact. But it is not necessary to use refrigerants made from harmful substances when there are alternatives. Natural refrigerants - including carbon dioxide, ammonia and hydrocarbons - have no or almost no global warming potential (GWP), no ozone depletion potential (ODP), and do not harm the environment in other ways. That's why these refrigerants are the foundation for sustainable heating and cooling systems of the future and the rapid transition to natural refrigerants is both urgent and vital.
founder & CEO, atmosphere
Marc Chasserot is a specialist in natural refrigerants with more than two decades of experience working with climate-friendly technologies. In 2007 he founded Shecco, a global, independent market accelerator with a mission to clean up cooling. It recently repositioned itself as ATMOsphere so it could better address the global need to scale up the clean cooling economy.
