The GHG Protocol consists of four separate but linked standards:

Corporate Accounting and Reporting Standards (Corporate Standard): methodologies for business and other organizations to inventory and report all of the GHG emissions they produce. “Corporate,” in this context, refers to both private and public sector organizations. The Calculation Tools are a complement to the Corporate Standard and assist businesses in quantifying emissions from their business activities and operations.

Project Accounting Protocol and Guidelines: geared toward calculating reductions in GHG emissions from specific GHG-reduction projects. The Project Protocol is the most comprehensive, policy-neutral accounting tool for quantifying the greenhouse gas benefits of climate change mitigation projects.

Corporate Value Chain (Scope 3) Accounting and Reporting Standard:allows companies to assess their entire value chain emissions impact and identify the most effective ways to reduce emissions. Often, the majority of total corporate emissions come from scope 3 sources, which means many companies have been missing out on significant opportunities for improvement. Users of the new standard can now account for emissions from 15 categories of scope 3 activities, both upstream and downstream of their operations. The scope 3 framework also supports strategies to partner with suppliers and customers to address climate impacts throughout the value chain.

Product Life Cycle Accounting and Reporting Standard: can be used to understand the full life cycle emissions of a product and focus efforts on the greatest GHG reduction opportunities. This is the first step towards more sustainable products. Using the new standard, companies can measure the greenhouse gases associated with the full life cycle of products including raw materials, manufacturing, transportation, storage, use and disposal. The results can create competitive advantage by enabling better product design, increasing efficiencies, reducing costs, and removing risks. The standard will also help companies respond to customer demand for environmental information and make it easier to communicate the environmental aspects of products.
