Over three-quarters of global Greenhouse Gas (GHG) emissions (predominantly in the form of Carbon Dioxide CO2) come from energy consumption, which can be broken down into the main categories of; industry-related consumption (24.2%), buildings (17.5%) and transport (16.2%). These are due to the burning of fossil fuels from coal, oil, gas and other hybrid fuels. To decarbonise our energy system, we need to switch to renewable energy such as solar, wind, hydro, tidal, bio mass, and shift transportation towards low-carbon electricity.
Getting to a net-zero-carbon energy system is essential. It will be a major effort, one that requires significant investment in new low-carbon infrastructure, from renewable power plants to electric vehicles, efficient appliances and better constructed buildings.
