Changes in the global climate and increased emissions from preindustrial levels challenge biodiversity and ecosystem services. The increasing energy demand and fossil fuel consumption drive global carbon emissions. This chapter introduces the organization’s carbon accountingCarbon accounting measures for reducing greenhouse gas emissions. Most companies account for their carbon footprintCarbon footprint with the objective of reducing future carbon emissions and taking significant measures for carbon reduction. The carbon accounting procedure considers the Scope 1Scope 1, Scope 2Scope 2, and Scope 3Scope 3 emissions of an organization. Carbon accountingCarbon accounting is a complex accounting procedure that requires real-time emission and historical energy data and emission factors. This chapter introduces the procedure of emission accounting with examples of companies such as SSE Energy Solutions and AppleApple’s carbon footprint Inc. These illustrations provide insights into why companies do their emission accounting and provide strategies for reducing emissions in each of the scopes. The carbon accounting procedure has gained popularity, as stakeholders such as investors, policymakers, and consumers prefer to account for carbon emissions, with a focus on achieving net-zero emissions and aiming to reduce the risk of their investments.
