Did CO2 emissions increase or decrease this year?

Grade level: 4 – 6th grades

Math Skills: Percentage

Carbon dioxide (CO2) emissions dropped by 7% in the world this year. This is the biggest annual fall in CO2 since World War II.

CO2 emissions in 2019 were 4.5 tons per person. How much of CO2 was emitted per person in 2020?


Answer

4.5×0.07=0.315

4.5 – 0.315 = 4.185 ≈ 4.2 (tons)

Or

4.5×0.93=4.185 ≈ 4.2 (tons)
