Measuring to Manage: A Guide to Designing GHG Accounting and Rep As concern about climate change climbs to unprecedented levels, one of the most important steps that a country, region, or state can take to address it is to establish a sound and credible platform to account for and report greenhouse gas (GHG) emissions from corporations. Over the past decade, many efforts to design and implement programs to promote the measurement and management of corporate GHG emissions have emerged around the world.
