Our growing climate crisis demands that we conserve energy and water, reduce waste, and find ways to protect our ecosystems. But the most urgent challenge facing us globally may be to reduce our carbon emissions.

We need a common foundation to ensure that Scope 1, 2, and 3 emissions are measured in an accurate, consistent, and reliable way.
