A Low-Carbon Economy (LCE) or Low-Fossil-Fuel Economy (LFFE) is an economy which has a minimal output of greenhouse gas (GHG) emissions into the biosphere, but specifically refers to the greenhouse gas carbon dioxide.

Recently, most of scientific and public opinion has come to the conclusion there is such an accumulation of GHGs (especially CO2) in the atmosphere due to anthropogenic causes, that the climate is changing.

The over-concentrations of these gases is producing global warming that affects long-term climate, with negative impacts on humanity in the foreseeable future. Globally implemented LCE's therefore, are proposed as a means to avoid catastrophic climate change, and as a precursor to the more advanced, zero-carbon society and renewable-energy economy.
