Greenhouse Gas Accounting for Manufacturers

Legislation and stakeholders increasingly urge European original equipment manufacturers (OEM) to disclose and reduce greenhouse gas (GHG) emissions of their operations and supply chains. However, a sector-specific reporting standard is not yet available for manufacturing industry. This study takes a stepwise approach to identify the GHG emission sources and intensities in further detail. The primary data of a case company, a Finnish gear manufacturer, was supplemented with secondary data from the literature. Using the proposed approach, an OEM share of the total emissions was estimated at 15%. Evaluating emissions of specific suppliers is more difficult as there is little access to the suppliers’ data. The study gives insights for the manufacturers on how to get started with GHG emissions accounting in the factories and supply chains and to show their responsible actions in the climate change mitigation.
