Regulations for Emissions from Vehicles and Engines

Final Rule for Mandatory Reporting of Greenhouse Gases

On this page:

Rule Summary

EPA is promulgating a regulation to require reporting of greenhouse gas emissions from all sectors of the economy. The final rule applies to fossil fuel suppliers and industrial gas suppliers, direct greenhouse gas emitters and manufacturers of heavy-duty and offroad vehicles and engines. The rule does not require control of greenhouse gases, rather it requires only that sources above certain threshold levels monitor and report emissions.
