A low-carbon economy (LCE) is an economy which absorbs as much greenhouse gas as it emits.[2] Greenhouse gas (GHG) emissions due to human activity are the dominant cause of observed climate change since the mid-20th century.[3] There are many proven approaches for moving to a low-carbon economy, such as encouraging renewable energy transition, energy conservation, and electrification of transportation (e.g. electric vehicles). An example are zero-carbon cities.
Shifting from high-carbon economies to low-carbon economies on a global scale could bring substantial benefits for all countries.[4] It would also contribute to climate change mitigation.
