Today we review estimates of CO2 emitted by the two largest sources in a medium-sized Swiss town: emissions from homes and vehicles. While it has long been known that these two sources account globally for 70% of greenhouse gas emissions, this research looks at grouping within the population and found that larger houses (which makes up about a fifth of the total) and drivers with longer commutes accounted for more than 50% of the total. This suggests that a focus on home and vehicle energy efficiency (or on smaller homes and shorter commutes) would produce the most effective results, to the extent that reducing the emissions of these two groups by 50% would reduce the overall total by 25%.
