This flow chart shows the sources and activities across the U.S. economy that produce greenhouse gas emissions. Energy use is by far responsible for the majority of greenhouse gases.
Measurement is critical to effective greenhouse gas (GHG) management. As the
United States moves toward a low-carbon economy, companies find it imperative that
they keep track of their GHG emissions. This fact sheet answers key questions about
corporate GHG inventories and how they relate to other GHG measurement initiatives.
By mid-2008, the U.S. Environmental Protection Agency must develop a national
greenhouse gas (GHG) registry. This is not part of ongoing climate policy discussions,
it is already law. This fact sheet answers the questions many are asking about GHG
registries and the role of a mandatory GHG reporting program in the United States.
This policy brief looks at the rationales for a national greenhouse gas registry in the United States, draws comparisons to other reporting programs and proposals, and makes recommendations on key design questions.
A guide on design and implementation of effective GHG programs based on internationally accepted standards and methodologies for GHG accounting and reporting.
