The GHG Protocol consists primarily of two 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. Click here for more information on the Corporate Standard.
	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.
