Challenges in the Computation of Emissions Related to Purchased Goods for Food Retail Sector Companies

Abstract
Companies across the world are reporting the emissions as per the guidance of the Greenhouse Gas (GHG) protocol [1]. The GHG protocol distinguishes value chain emission in 15 different categories. Purchased goods and services is one of the vital categories for the emissions, which includes cradle-to-gate emissions for purchased goods & services by the company. The food retail sector, which acts as a midstream value chain partner for farmers, dairies, poultries, food ingredients, and the end consumers (Restaurants or individuals), is facing challenges in the computation of emissions related to purchased goods due to the lack of availability of supplier or product-specific emission factors, a large number of suppliers, and ambiguity on double accounting. This paper focuses on the methods for emission computation adopted by some global food retail sector companies and underlines the challenges in computation for emissions due to purchased goods.
