The document discusses greenhouse gas emissions from agriculture and land use in Wales from 2007. It presents various scenarios to reduce emissions by 2040 including: expanding woodlands; increasing renewable energy; improving farm productivity; reducing animal products in diet; and increasing crops and horticulture. The preferred scenario would reduce net emissions from 5,200 kt CO2e to around 2,000 kt CO2e by 2040 through these interventions while producing 3 TWh each of renewable heat and electricity, saving an additional 1,500-2,000 kt CO2e annually.
