Carbon is found in all of Earth’s ecosystems. It is packed into the trees and soils of forests, lies dense and deep in tropical peatlands and frozen tundra, maintains the fertility and resilience of farms, rangelands, and fisheries around the globe.

Land and oceans are natural “carbon sinks”, absorbing more than half of all greenhouse gas emissions, sparing the world from even more rapid warming. But, the loss of nature and conversion of land for agriculture and other activities caused nearly a quarter of emissions in the decade through 2016. Rising temperatures also risk turning carbon sinks into carbon sources.

Preventing the loss of carbon stocks in Earth’s ecosystems is critical to address the climate and biodiversity emergencies. As leaders debate policy options at the COP26 climate summit, a new report from the United Nations Environment Programme (UNEP) highlights the need for nature-based solutions - locally appropriate actions that address societal challenges, such as climate change, and provide human well-being and biodiversity benefits by protecting, sustainably managing and restoring ecosystems.
