Join our community of diverse organizations that measure and report their carbon emissions using our programs. Our members include leaders from all sectors such as the US Postal Service, the University of California school system, Qualcomm Inc., and Delta.
A GHG inventory, also known as a “carbon footprint”, is a representation of an organization’s impact on global climate change over a specific time in terms of greenhouse gases emitted either directly or indirectly.
There are a number of different kinds of GHG inventories, but TCR members report corporate inventories. Corporate inventories are quantifications of the greenhouse gases emitted by an organization’s operations, and include emissions that fall within their geographical, organizational, and operational boundaries. Corporate inventories enable organizations to identify opportunities to reduce emissions as well as track changes over time. GHG inventories reported to TCR are organized by “Scopes”. Scopes of emissions are used to distinguish between greenhouse gases that are directly emitted, and those that are indirectly emitted.
The General Reporting Protocol (GRP) outlines the best-practice greenhouse gas accounting policies and emissions calculation methodologies that our members adhere to when reporting to our voluntary program. The GRP is developed and maintained through a comprehensive public stakeholder process that aggregates input from industry experts across multiple sectors, environmental non-governmental organizations, companies, regulatory agencies, and individuals.
Verification is a third-party audit of an organization’s greenhouse gas inventory by a TCR-approved verification body. It ensures that inventories reported to TCR are free from misstatements and conform to TCR’s protocols. Verification is not required for TCR members, but only verified inventories are made publicly available on our website and the CRIS public reports page to ensure that only credible, high quality data is put into the public domain.
Verification is an additional, separate cost to membership. Due to the variability of factors behind verification costs, TCR cannot provide estimates for the cost of verification. We recommend that you consult directly with a TCR-approved verification body for estimates, and reference the Verification page of our website to get an idea for the factors that affect the cost of verification.
