Corporate Value Chain Standard and Calculation Guidance (Scope 3)

The Corporate Value Chain (Scope 3) Accounting and Reporting Standard allows companies to assess their entire value chain emissions impact and identify where to focus reduction activities.

An effective corporate climate change strategy requires a detailed understanding of a company’s greenhouse gas (GHG) emissions. Until recently, most companies have focused on measuring emissions from their own operations and electricity consumption, using the GHG Protocol’s scope 1 and scope 2 framework. But what about all of the emissions a company is responsible for outside of its own walls—from the goods it purchases to the disposal of the products it sells?

The Scope 3 Standard is the only internationally accepted method for companies to account for these types of value chain emissions. Building on this standard, GHG Protocol has now released a companion guide that makes it even easier for businesses to complete their scope 3 inventories.
