How to limit emissions from agriculture is becoming an acute issue in the EU's green policy, with this sector lagging behind other areas of the economy in reducing its impact on the climate. Since climate change provisions within Common Agricultural Policy (CAP) haven't caused major problems, policymakers are looking again at a promising but complicated idea: the introduction of an emissions trading system (ETS) specifically for agriculture. The ETS is a cap-and-trade system in which economic entities are provided with a permitted volume of carbon credits that they can buy and sell to each other. The original ETS The EU, introduced in 2005, has helped reduce emissions from energy production, manufacturing and flights within Europe. This year the politicians approved Types ETS to cover buildings, road transport and other sectors, which will enter into force in 2027. (FEDERICA DI SARIO)
