Graphics based on data from WRI's CAIT Climate Data Explorer answer questions like: How have emissions changed over time? Which human activities contribute the most emissions? And who are the world's biggest emitters?
New data in WRI’s CAIT Climate Data Explorer shows that the top 10 emitters contribute 72 percent of global emissions; the bottom 100 contribute only 3 percent.
The report provides comprehensive, step-by-step guidance for policymakers to design mandatory greenhouse gas reporting programs.
At least 40 countries and several sub-national regions have implemented greenhouse gas reporting programs. A new report provides step-by-step guidance on how policymakers can design them effectively.
Insights from Ten Countries
This working paper provides a synthesis of country experiences with data management systems for national GHG inventories, based on survey responses from both Annex I and non-Annex I Parties.
Potential emissions of oil and gas companies’ fossil fuel reserves could make or break whether the world stays within its "carbon budget."
Approximately 40 percent of the world’s greenhouse gas emissions come from energy generation, and about half of that energy is consumed by industrial or commercial users.
If a fifth of the world’s emissions come from the energy that keeps the world’s businesses running, how does business report those emissions?
An amendment to the GHG Protocol Corporate Standard
This new Scope 2 Guidance represents a four-year global collaboration to harmonize methods for how companies report greenhouse gas (GHG) emissions from purchased electricity, steam, heat, and cooling (called scope 2 emissions).
It amends the existing...
Today, WRI, the C40 Cities Climate Leadership Group, and ICLEI – Local Governments for Sustainability are launching the final version of the Global Protocol for Community-Scale Greenhouse Gas Emissions Inventories (GPC). It’s the first internationally accepted standard for measuring emissions at the city level, and empowers cities to accurately identify where their emissions are coming from, set credible and achievable reduction targets, and consistently track progress.
