Higher energy demand drove up global CO2 emissions in 2018
We released our second annual report on global energy trends last week, highlighting that energy demand worldwide grew by 2.3% in 2018, its fastest pace this decade, thanks to a strong global economy and higher demand for heating and cooling.
Natural gas emerged as the fuel of choice, posting the biggest gains and accounting for 45% of the rise in energy consumption. Solar and wind generation grew at double-digit pace, with solar alone increasing by 31%. Still, that was not fast enough to meet higher electricity demand around the world that also drove up coal use.
As a result, global energy-related CO2 emissions rose by 1.7% to 33 Gigatonnes (Gt) with coal use in power generation alone surpassing 10 Gt and accounting for a third of total emissions. The majority of that was from coal-fired generation capacity in Asia, with a fleet of young power plants that are decades short of average lifetimes of around 50 years.
