Germany: CO2 Country Profile - Our World in Data

When countries set targets, measure or compare CO 2 emissions, they tend to focus on production-based emissions – CO 2 emitted within a country’s own borders. However, this fails to capture emissions from traded goods – the CO 2 emitted in the production of goods elsewhere, which are later imported (or the opposite: emissions from goods that are exported).
