Pie chart: Greenhouse gas emissions by sector

The pie chart shows the percentage of greenhouse gas emissions produced by each of five sectors in one country.

Overall, the energy sector was by far the largest source of emissions, whereas waste contributed only a small fraction of the total. The three sectors in the middle accounted for similar shares.

Energy produced 42% of all emissions, more than twice the share of industry, which was the second-largest contributor at 20%. Together, these two sectors were responsible for 62% of the total, almost two-thirds of emissions.

Agriculture and transport had very similar figures, at 17% and 16% respectively, so each accounted for roughly one-sixth of emissions. These two sectors combined produced 33%, which was still clearly less than the contribution of the energy sector on its own.

Waste was the smallest source, at just 5%. This was around one-eighth of the energy figure and less than a third of the share produced by transport. Each of the other four sectors therefore generated at least three times as much as waste.
