Agriculture and land use significantly contribute to global greenhouse gas emissions. Governments around the world provide about $600 billion annually to support agriculture. Currently, this support does not greatly increase global greenhouse gas emissions from farming. The support used to encourage high-emission farming practices in the past. However, it now has only a small impact on emissions because it is not focused on high-emission products. Trade protections also reduce the demand for some high-emission products by making them more expensive for consumers. To reduce greenhouse gas emissions from agriculture and ensure food security, there is a need to reform the current support system for agriculture and food consumption.
