The purpose of this law is to ensure that national climate protection targets and European targets are met to protect against the effects of global climate change. The ecological, social and economic consequences are taken into account. The basis is the obligation under the Paris Agreement based on the United Nations Framework Convention on Climate Change, according to which the increase in global average temperature must be limited to well below 2 degrees Celsius and, if possible, to 1.5 degrees Celsius compared to the pre-industrial level in order to reduce the effects of global climate change as low as possible, as well as the commitment of the Federal Republic of Germany at the United Nations climate summit on September 23, 2019 in New York to pursue greenhouse gas neutrality by 2050 as a long-term goal.
