EPA 608 Core · Ozone Depletion · Easy
Which metric compares a gas's global warming impact to carbon dioxide?
Answer: C. Global Warming Potential (GWP).
- AOzone Depletion Potential (ODP).
- BTotal Equivalent Warming Impact (TEWI).
- CGlobal Warming Potential (GWP).✓ Correct
- DCoefficient of Performance (COP).
Why C is right
GWP is a relative scale where CO2 is the baseline with a value of exactly 1.
