Ambitious plans to make farming ‘net zero’ by 2040 - 10 years ahead of the UK’s legally-binding national target – may not be achieved, the National Farmers’ Union (NFU) has told the BBC.

Reaching net zero means no longer adding to the total amount of greenhouse gases already in the atmosphere. The NFU said a lack of investment in climate-friendly farming measures by the previous government had made doing that by 2040 “tricky” but insisted that the deadline would not be dropped.

Meanwhile, the Soil Association warned that UK agriculture would not be able to reach net zero greenhouse gas emissions “without radical changes".
