A company set a target to reduce its emissions by 42% from a baseline of 50,000 tonnes CO2e. Its emissions for the current year are 38,500 tonnes CO2e. By how many further tonnes CO2e must emissions fall from the current level to meet the target?

Correct answer: A) 9,500 tonnes CO2e

Explanation

The target level is 50,000 x (1 - 0.42) = 29,000 tonnes CO2e. The further reduction needed is 38,500 - 29,000 = 9,500 tonnes CO2e. The figure of 11,500 is the reduction already achieved (50,000 - 38,500), 21,000 is the total reduction required from the baseline, and 16,170 wrongly applies the 42% to the current year's emissions.
