Companies including Nestle, Unilever, Mahindra Group and Volvo Cars are urging political leaders to agree a timeline at the upcoming U.N. climate summit to phase out fossil fuels. From a report: The 131 companies, which have nearly $1 trillion in global annual revenues, wrote in a letter published on Monday that attendees at the COP28 summit must commit to reach 100% decarbonised power systems by 2035 for richer economies, and help developing countries financially so they can ditch fossil fuels by 2040 at the latest. "Our businesses are feeling the impacts and cost of increasing extreme weather events resulting from climate change," the companies wrote in the letter, which was coordinated by the non-profit We Mean Business Coalition, which is pushing for greater climate action globally.

"To decarbonise the global energy system, we need to ramp up clean energy as fast as we phase out the use and production of fossil fuels," they wrote. The letter's 131 signatories, which include Bayer, Heineken, IKEA and Iberdrola, span a range of sectors and include multinationals and small and medium-sized businesses. Companies are increasingly committing to their own timelines for reducing their emissions, but many acknowledge that their ability to slow planet-warming CO2 emissions is contingent on faster action from governments.
