GHG Emissions 101: The GHG emissions reporting handbook by KMPG

The purpose of this GHG emissions Reporting handbook by KPMG is to assist users in understanding the accounting and reporting of GHG emissions through the lens of the following standards and guidance of the Greenhouse Gas Protocol:

  • A Corporate Accounting and Reporting Standard
  • Scope 2 Guidance
  • Scope 3 Corporate Value Chain Accounting and Reporting Standard

Climate-related disclosure requirements are being finalized by the International Sustainability Standards Board (ISSB), the European Financial Reporting Advisory Group (EFRAG), and the SEC. These requirements are likely to shape the global climate reporting landscape. While they differ in several aspects, these upcoming requirements all have a common foundation: greenhouse gas emissions.

The Protocol outlines essential principles, concepts, and methods for creating a greenhouse gas (GHG) emissions inventory, which can serve both voluntary and mandatory reporting needs. As the Protocol shapes the future of emissions reporting, finance professionals are increasingly crucial in translating scientific data into investor-quality information.

Understanding the basics of GHG emissions reporting is becoming vital for those in finance to effectively bridge the gap between technical data and the financial insights investors require.

The following diagram provides a roadmap to the elements of emissions reporting under the GHG Protocols that are discussed in this handbook. The diagram illustrates business travel as the only scope 3 category included in the operational boundary and therefore in the inventory boundary.
