Most countries, including Switzerland, record their greenhouse gas emissions by source and sector. In absolute terms, Swiss greenhouse gases make up less than 1% of global emissions. With an average of 12 metric tons of CO2 equivalents per capita per year, however, the Swiss are polluting the climate about twice as much as the average person globally if we take into account the emissions of our imported goods. This average value is useful for international comparisons, but it ignores differences between individuals or groups of people within Switzerland.
