Research on the Greenhouse Gases Emission Reduction of Pig-breeding Industry in China

Abstract

Pig-breeding process can emit a lot of CH4, N2O and CO2. The contribution rate of pig-breeding in greenhouse gases emission stands first on the list of all livestock breeds in China. The paper gave the way to reduce carbon emission in pig-breeding industry by the respective of environmental techniques.The results showed that we should use the three biogas products and provide households the chances of taking part in clean development mechanism to promote the scientific treatment of pig waste and to reduce emission finally.
