The term carbon-free economy (also called post-fossil economy ) describes the vision of an economic system that is operated with complete renunciation of carbon dioxide emissions . The transition from the current carbon-based economy to a low-carbon economy to a carbon-free economy is known as decarbonization .

background

Necessary paths to reduce greenhouse emissions in order to meet the two-degree target agreed in the Paris Agreement without negative emissions , depending on when the emissions turnaround

Climate scientists assume a CO 2 budget which, if exceeded , would result in unpredictable consequences in the form of a post-apocalypse , such as the state of the greenhouse earth , which would create conditions hostile to human life. The idea is assumed that at an average discharge in 2017 of about 40 Gt CO 2 equivalent per year (GtCO 2 e / a) of the human in the case of a missing change in the emissions, depending on the assumed CO 2 -Budget still about Stay 20 to 30 years until this budget is exhausted; thereafter, because of the very long-term absorption of greenhouse gases by the earth system, no greenhouse gases should be emitted for millennia. In order to keep the climate system for the human species within an appropriate framework in the long term, a rapid changeover of the economic system without greenhouse gases is necessary.

activities

Exemplary examples of measures to create a carbon-free economy are the abandonment of internal combustion engines (e.g. through alternative drive technologies such as electromobility ) and the conversion of an energy supply based on the combustion of coal, crude oil and gas to renewable energy . Even negative emissions contribute to a carbon-free economy.

In this context, a carbon-free economy is often associated with a circular economy and a post-growth society.
