Fossil fuel divestment or fossil fuel divestment and investment in climate solutions is an attempt to reduce climate change by exerting social, political, and economic pressure for the institutional divestment of assets including stocks, bonds, and other financial instruments connected to companies involved in extracting fossil fuels.
Smaller contributions come from black carbon (from combustion of fossil fuels and biomass), and from dust. [134] [135] [136] Globally, aerosols have been declining since 1990 due to pollution controls, meaning that they no longer mask greenhouse gas warming as much. [137] [53] Aerosols also have indirect effects on the Earth's energy budget.
UN Secretary-General Ban Ki-moon Definitions The United Nations Brundtland Commission described the concept of sustainable development, for which energy is a key component, in its 1987 report Our Common Future. It defined sustainable development as meeting "the needs of the present without compromising the ability of future generations to meet their own needs". This description of sustainable ...
Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane , natural gas , methane , and ammonia ; biofuels like biodiesel , bioalcohol , and refuse-derived fuel ; and other renewable fuels like hydrogen and ...
[68] [69] Many fossil fuel companies have made commitments to be net zero by 2050. [70] At the same time they continue to increase greenhouse gas emissions by extracting and producing fossil fuels. [71] They claim that they will use carbon credits and carbon capture technology in order to continue extracting and burning fossil fuels.
Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...

Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Cement production (burning of fossil fuels) (4%) is estimated at 1.42 GtCO 2; Land-use change (LUC) is the imbalance of deforestation and reforestation. Estimations are very uncertain at 4.5 GtCO 2. Wildfires alone cause annual emissions of about 7 GtCO 2 [98] [99] Non-energy use of fuels, carbon losses in coke ovens, and flaring in crude oil ...
