Low-carbon

A low-carbon economy (LCE), low-fossil-fuel economy (LFFE), or decarbonised economy is an economy based on low carbon power sources that therefore has a minimal output of greenhouse gas (GHG) emissions into the biosphere, but specifically refers to the greenhouse gas carbon dioxide. GHG emissions due to anthropogenic (human) activity are the dominant cause of observed global warming (climate change) since the mid-20th century. Continued emission of greenhouse gases will cause further warming and long-lasting changes around the world, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems.

Many countries around the world are designing and implementing low emission development strategies (LEDS). These strategies seek to achieve social, economic and environmental development goals while reducing long-term greenhouse gas emissions and increasing resilience to climate change impacts.

Globally implemented low-carbon economies are therefore proposed by those having drawn this conclusion, as a means to avoid catastrophic climate change, and as a precursor to the more advanced, zero-carbon economy.

Nations may seek to become low-carbon or decarbonised economies as a part of a national climate change mitigation strategy. A comprehensive strategy to mitigate climate change is through carbon neutrality.

The aim of a LCE is to integrate all aspects of itself from its manufacturing, agriculture, transportation, and power-generation, etc. around technologies that produce energy and materials with little GHG emission, and, thus, around populations, buildings, machines, and devices that use those energies and materials efficiently, and, dispose of or recycle its wastes so as to have a minimal output of GHGs. Furthermore, it has been proposed that to make the transition to an LCE economically viable we would have to attribute a cost (per unit output) to GHGs through means such as emissions trading and/or a carbon tax.
