Topic: emissions inventories

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.

The objective of WRI’s sustainability initiative is to “learn by doing” and to apply our research to reduce our own environmental footprint.

Climate Registry States

34 U.S. states, 2 Canadian provinces, and 2 Native American nation establish a single, unified GHG emissions accounting system.

An analysis of GHG Intensity targets, underlying indicators, rationales, real-world applications, and implementation issues.

The ACEA Agreement target in 2008 will entail costs for the industry that are likely to to distributed differently between the member companies. Yet these costs, along with their competitive implicatications, remain hidden from the public.

Changing Drivers: The impact of climate change on competitiveness and value creation in the automotive industry

Emerging carbon constraints constitute a new influence on competitiveness in the automotive industry, creating both risks and opportunities for companies that could materially affect their earnings and ability to compete in global markets.

Based on experiences gained implementing WRI’s CO2 reduction commitment, this guide helps other office-based organizations understand climate change and the practical steps they can take to measure and reduce their CO2 emissions.
