What is national GHG inventory?

Greenhouse gas inventories are emission inventories of greenhouse gas emissions that are developed for a variety of reasons. Scientists use inventories of natural and anthropogenic (human-caused) emissions as tools when developing atmospheric models.

How is greenhouse gas data collected?

The Greenhouse Gas Reporting Program (GHGRP) collects Greenhouse Gas (GHG) data from large emitting facilities, suppliers of fossil fuels and industrial gases that result in GHG emissions when used, and facilities that inject carbon dioxide underground. Learn more about the GHGRP.

How do companies measure GHG emissions?

Currently, GHGs are measured using the Climate Footprint Calculator, the Global Reporting Initiative (GRI), and resources from the World Business Council for Sustainable Development and the World Resources Institute.

What is scope 1 GHG Protocol?

Scope 1 emissions are direct greenhouse (GHG) emissions that occur from sources that are controlled or owned by an organization (e.g., emissions associated with fuel combustion in boilers, furnaces, vehicles).

What is the methodology of greenhouse?

The methodology allows users to estimate GHG impacts at project scale, GHG emissions by agricultural practice and GHG emissions per unit of output (i.e., GHG emission intensity).

How do you measure emissions?

Emissions are calculated most efficiently by simply measuring the amount of fuel used which automatically takes into account variability in both the vehicle and driving skill.

Who are the GHG Protocol?

GHG Protocol establishes comprehensive global standardized frameworks to measure and manage greenhouse gas (GHG) emissions from private and public sector operations, value chains and mitigation actions.

Who measures GHG emissions?

The EPA’s Greenhouse Gas Reporting Program (GHGRP) captures data covering 85-90% of all US GHG emissions.
