Greenhouse Gas Facts

The vast majority of the energy we consume to heat and light our homes and power our vehicles comes from fossil fuels, such as coal, natural gas and oil. When these fuels are burned, CO2 is emitted as a waste product.

• Coal is the most “carbon intensive” of the fossil fuels, since it generates the highest amount of CO2 per unit of energy produced.
• Over 60% of electricity in Alberta is produced from coal powered generators.
• For every kilowatt hour (kWh) of electricity used in Alberta, 0.93 kg of CO2 is emitted.
• For every litre of gasoline used, 2.4 kg of CO2 is emitted.
• For every gigajoule (GJ) of natural gas used, about 50 kg of CO2 is emitted.
