Countries and Cities

The Greenhouse Gas Protocol provides standards and tools that help countries and cities track progress toward their climate goals. 

The Paris Agreement marks a historic turning point in global climate action, committing all countries to limit global temperature rise, adapt to changes already occurring, and regularly increase efforts over time.

GHG Protocol standards help countries and cities design climate mitigation goals, assess and report progress toward goal achievement, and estimate the greenhouse gas effects of policies and actions.

We are also working to give cities the standards and tools they need to measure their emissions, build more effective emissions reduction strategies, set measurable and more ambitious emission reduction goals, and track their progress more accurately and comprehensively.
