NEW STUDY FINDS NATURE IS VITAL TO BEATING CLIMATE CHANGE

Washington DC, USA and London, UK, 16 October 2017 – Better stewardship of the land could have a bigger role in fighting climate change than previously thought, according to the most comprehensive assessment to date of how greenhouse gas emissions can be reduced and stored in forests, farmland, grasslands and wetlands using natural climate solutions.

The peer-reviewed study, led by scientists from The Nature Conservancy and 15 other institutions[1], and published today in the journal Proceedings of the National Academy of Sciences*, expanded and refined the scope of land-based climate solutions previously assessed by the United Nations’ Intergovernmental Panel for Climate Change (IPCC). The findings are expected to bolster efforts to ensure that large-scale protection, restoration, and improved land management practices needed to stabilize climate change are achieved while meeting the demand for food and fiber from global lands.

Accounting for cost constraints, the researchers calculated that natural climate solutions could reduce emissions by 11.3 billion tonnes per year by 2030[2] – equivalent to halting the burning of oil[3], and offering 37% of the emissions reductions needed to hold global warming below 2 degrees Celsius by 2030. Without cost constraints, natural climate solutions could deliver emissions reductions of 23.8 billion tonnes of carbon dioxide equivalent per year, close to a third (30%) more than previous estimates[4].

Mark Tercek, CEO The Nature Conservancy said: “Today our impacts on the land cause a quarter of greenhouse gas emissions. The way we manage the lands in the future could deliver 37% of the solution to climate change. That is huge potential, so if we are serious about climate change, then we are going to have to get serious about investing in nature, as well as in clean energy and clean transport. We are going to have to increase food and timber production to meet the demand of a growing population, but we know we must do so in a way that addresses climate change.”

Christiana Figueres, convener of Mission 2020 and former head of the UN Framework Convention on Climate Change (UNFCCC), said: “Land use is a key sector where we can both reduce emissions and absorb carbon from the atmosphere. This new study shows how we can massively increase action on land use – in tandem with increased action on energy, transport, finance, industry and infrastructure – to put emissions on their downward trajectory by 2020. Natural climate solutions are vital to ensuring we achieve our ultimate objective of full decarbonisation and can simultaneously boost jobs and protect communities in developed and developing countries.”
