Strategic principles of the Long-Term Climate Strategy The Long-Term Climate Strategy outlines how the net-zero target can be achieved by 2050. Building on the progress achieved by the complete revision of the CO₂ Act, the climate strategy shows emissions developments, targets and the related challenges, going beyond the year 2030 and for the various sec- tors. The relevant future legal framework conditions can be defined on this basis. 22 According to the Federal Statistical Office, just under two-thirds of Switzerland's total greenhouse gas footprint is generated abroad, see https://www.bfs.admin.ch/bfs/en/home/statistics/territory-environment/environmental-accounting/air-emissions.html. The FOEN uses a slightly different method in its estimations, but includes a similar Switzerland/abroad ratio.
