Background of emission factor 

Hydrogen is a promising alternative to fossil fuels, especially in transport and industry. It produces zero emissions during use, as the only byproduct of combustion is water vapor. However, the lifecycle emissions depends on how the hydrogen is produced. When made with renewable energy, it’s called green hydrogen; when made from fossil fuels, it’s known as grey hydrogen.

Emission factor category

The emission factor for fuels shows how much emissions are caused by burning the fuel. Carbon dioxide emissions occur when the carbon in the fuel combines with oxygen during combustion. Most global greenhouse gas emissions are caused by burning fossil fuels (coal, natural gas and oil)
