The United States is calculated to emit a new record high in CO2 for 2018, at 37.B tonnes of emissions. This would make for a 2% increase, within a range of 1.8% and 3.7%. With the United States being the second largest polluter in the word, contributing 15% of total human based emissions. China is the largest polluter in total volume, bringing in 27% of the total emissions.
This still brings the United States, per capita, to the number one spot. Roughly 55% of the total is generated by transport and energy. Another 9% comes from herding our food sources.
Coal being the largest producer of these emissions, as it is considered the "dirtiest" form of all fossil fuels.
The EU (European Union) is able to shave of about 0.7% of their total emissions, but this is also still far below the set targets and guidelines introduced at the Paris Accord
