The Greenhouse Gas Protocol is a step-by-step guide for companies and other types of organizations to use in identifying, quantifying and reporting their greenhouse gas emissions.
Arising from a joint initiative between World Resources Initiative and the World Business Council for Sustainable Development, the GHGP first published its Corporate Standard in 2001.
Having a common standard improves the consistency, transparency, and understandability of reported information, making it easier to track and compare progress over time.

The GHG Protocol was designed for several reasons:
Carbon accounting is based on a set of principles — just like in financial accounting. The GHG Protocol identifies five principles on which carbon accounting and reporting shall be based:
For an organization’s GHG report to be relevant means that it contains the information that users — both internal and external to the company — need for their decision making.
All relevant emissions sources within the chosen inventory boundary need to be accounted for so that a comprehensive and meaningful inventory is compiled. Any specific exclusions must be disclosed and justified.
The consistent application of accounting approaches, inventory boundary, and calculation methods is essential to producing an apples-to-apples comparison of GHG emissions over time and across operations.
Information must be recorded and analyzed in a way that enables internal and external stakeholders to attest to its credibility. A “transparent” report will provide a clear understanding of the issues in the context of the reporting company and a meaningful assessment of performance.
Data should be representative to enable users to make decisions with reasonable assurance that the reported information is credible.
The primary function of the five principles is to guide the implementation of the GHG Protocol, particularly in situations where application of the standard might be ambiguous.
The application of these five principles helps ensure that the resulting greenhouse gas inventory is a fair and accurate representation of the company’s greenhouse gas emissions.
