The saw the largest decline in energy-related CO emissions in 2019 on a country basis – a fall of 140 Mt, or 2.9%, to 4.8 Gt.
US emissions are now down almost 1 Gt from their peak in the year 2000, the largest absolute decline by any country over that period. A 15% reduction in the use of coal for power generation underpinned the decline in overall US emissions in 2019. Coal-fired power plants faced even stronger competition from natural gas-fired generation, with benchmark gas prices an average of 45% lower than 2018 levels. As a result, gas increased its share in electricity generation to a record high of 37%. Overall electricity demand declined because demand for air-conditioning and heating was lower as a result of milder summer and winter weather.
And all that without draconian taxes and freedom stealing restrictions on activities.
