Global CO2 emissions were stable from 2014 to 2016 but grew by 1.4% in 2017 and 2.1% in 2018 to 36.58 billion tonnes of CO2 equivalents. Despite some progress in expanding use of low carbon sources of energy, renewable fuels, and increased efficiency, growth in energy use from fossil fuel sources is still outpacing the rise of low-carbon sources and activities.(Jackson, R.B. 2019)

Global emissions of CO2 from fossil fuels and industry increased by 2.2% per year on average between 2005 and 2015 (Le Quere C 2018). In order to achieve the goals of the Paris Climate Agreement global emissions need to peak and decline rapidly to limit climate change to below 2 °C of warming.
Scientists once hoped that CO2 emissions could be held below the “tipping point,” now the plan is to quickly reach peak emissions and then reverse course reducing global net human-caused CO2 emissions by about 45 % from 2010 levels by 2030 and reaching ‘net zero’ emissions around 2050. (Forbes, 2019). Peak emissions will occur when improvements in the CO2 emitted per unit energy overcome the growth in global energy use. This requires that fossil fuels are replaced by low or no-carbon technologies and we further decouple global GDP from CO2 emissions.
The IPCC 2018 report tells us that climate change has arrived. Average global temperatures have already risen 1.1°C above preindustrial levels and, at current rates of warming, are projected to reach 1.5°C within two decades. A generally growing global economy (when not in Covid-19 shutdowns), insufficient emission reductions in developed countries, and a vast expansion in CO2 emitting energy use in developing countries where per capita emissions remain far below those of wealthier nations will continue to put upward pressure on CO2 emissions. The trajectory of growth in CO2 emission put the planet on a path of warming that is currently well beyond 1.5°C and, potentially, 2°C goals of the Paris Agreement.
Despite the President’s talking points to coal miners and the rollback of several environmental regulations over the past three years, the U.S. CO2 emissions have continued to fall as natural gas has replace coal as the primary fuel in electric supply. In 2019 CO2 emissions declined by about 1.7% after growing 2.8% in 2018, the Global Carbon Project finds that on average U.S. CO2 emissions have decreased about 1% each year for the last 15 years. During that same period China’s CO2 emissions have more than doubled
