UK Carbon Dioxide Emissions

The rate of CO₂ emissions for the UK was measured every 5 years, from 1990 to 2015.

The results are given in the table below with the rate of CO₂emissions measured in x10⁹kg year^-1

Year	1990	1995	2000	2005	2010	2015
Rate of CO₂emissions (x10⁹ kg year^-1)	595.7	557.5	555.7	555.2	496.7	403.8

Using all of this information,

a) Estimate the total CO₂ emissions from the UK between 1990 and 2015, giving your answer in standard form.

[3 marks]

Given that the curve produced by plotting a graph of the rate of CO₂ emissions against the year is concave,

b) Explain whether your answer to part (a) is an underestimate or an overestimate of the total CO₂ emissions between 1990 and 2015.
