If we are going to save the world it begins with changing the way we grow and access our food.

The new research– undertaken by three scientists working with Greenpeace, IATP and GRAIN– provides the first estimate of the global climate impacts of synthetic N fertilisers to cover the entire production chain, from manufacturing to soil application. It finds that the production and use of synthetic N fertiliser accounts for 2.4% of global emissions, making it one of the top climate polluting industrial chemicals. The synthetic N fertiliser supply chain was responsible for estimated emissions of 1,250 million tonnes of CO2e in 2018, which is roughly 21.5% of the annual direct emissions from agriculture (5,800 million tonnes).
