Detailed explanation-1: -Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil. Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant [1].

Detailed explanation-2: -There are four main types of low-carbon energy: wind, solar, hydro or nuclear power. The first three are renewable, which means these are good for the environment – as natural resources are used (such as wind or sun) to produce electricity.

Detailed explanation-3: -Because natural gas use yields CO2 emissions that are about 45 percent lower per Btu than coal and 30 percent lower than oil, its apparent abundance raises the possibility that natural gas could serve as a bridge fuel to a future with reduced CO2 emissions.

Detailed explanation-4: -Natural gas is often promoted as a cleaner energy source than coal and oil. However, natural gas is still a fossil fuel and accounts for a fifth of the world’s total carbon emissions.
