Chevron announces "aspiration" to be carbon neutral by 2050

How it works: The commitment covers Chevron's projects and energy use but does not cover Scope 3 emissions — that is, CO2 from the use of a company's products, like gasoline, in the wider economy. Scope 3 is the largest share of industry CO2 output.

Yes, but: However, Chevron is including Scope 3 in an updated, nearer-term pledge to cut intensity — that is, emissions per unit of output.
