20000 pounds

Explanation:

Generally 1 gallon of fuel burnt gives of 20 pounds of CO₂

Difference in the gallons of fuel burnt

\dfrac{60000}{20}-\dfrac{60000}{30}=1000\ gal

The 20 mpg car burns 1000 gallons of fuel more than the 30 mpg car

The amount of CO₂ would be

1000\times 20=20000\ pounds

The fewer pounds that the 30 mpg car would release is 20000 pounds
