Reducing Strategies for Carbon Footprint of Livestock in Izmir/Turkiye

Abstract

AbstractThe goal of the Paris Agreement is to limit the global average temperature increase to 1.5 °C. In order to significantly reduce the risks and impacts of climate change, greenhouse gas emissions must be reduced as soon as possible. By signing the Paris Agreement in 2021, Turkiye has committed to reducing greenhouse gas emissions by 41% by 2030. The livestock sector, which is an important economic resource, also has a significant share in greenhouse gas emissions in Turkiye. In this study, it was analyzed the greenhouse gas emissions resulting from livestock in Izmir, the 3rd largest city of Turkiye. For this purpose, greenhouse gas emissions and carbon footprint resulting from livestock farming in Izmir were calculated according to the IPCC 2019 Guidelines and Tier 1 methodology. The total carbon footprint of livestock in Izmir was determined as 2826.5 thousand tons CO2eq (ttonCO2eq). These total emissions were calculated as 1492 ttonCO2eq (53%) from enteric fermentation, 1120.5 ttonCO2eq (39%) from CH4 in manure management, and 214 ttonCO2eq (8%) from N2O in manure management. Sustainable method suggestions were also studied in order to achieve Turkiye’s greenhouse gas reduction commitment. The results show that a sustainable change in manure management method, such as biogas production from manure, can reduce the carbon footprint by 30%. As a result, sustainable manure management methods, nutrition, and animal welfare should be included in agricultural policies as methods that help reduce Turkiye’s greenhouse gas emissions.
