The Energy Information Administration recently reported US CO2 emissions from the consumption of energy for the first 6 months of 2022. Emissions are up 2.6% compared to the same period in 2021. Emissions increased about 8% in 2021, compared to the first half of 2020. Of course, 2020 was a year of world economic disruption because of the COVID response, so 2022 appears to be a continuation of the economic recovery. CO2 emissions this year are smaller, compared to the first 6 months of 2018 or 2019. Supply chains still appear to be messed up in several areas, and the effects of inflation (and the FED’s response to it) also impact the economy.
Looking at previous data, the following are the total CO2 emissions from energy for the years listed, just looking at the first half of each year.
Million metric tons CO2 2018 2,607 2019 2,563 2020 2,226 2021 2,411 2022 2,473
In the link, the CO2 sources are broken down by the big three fossil fuels (coal, natural gas and petroleum products). The Total column adds in a small amount from minor sources which are not specifically listed. It can also be noted that of the big three fossil fuels, the largest source of CO2 is petroleum, followed by natural gas. Coal comes in 3rd in the US.
In the US, the general trends are: Increasing CO2 emissions from natural gas, Decreasing CO2 emissions from coal, and mostly unchanged for petroleum. However, as previously stated, the economic effects of the past few years have disrupted these trends to a certain extent. With a more normal economy (inflation brought under control, supply chains back to normal), we might be able to better see how the CO2 trends are going.
Last point. Based on the current trends, meeting the goal of a 40% reduction in greenhouse gas emissions by 2030 (based on 2005) is going to be a major challenge. Greenhouse gases are more than just CO2. Just my opinion, but I don’t see it happening by the 2030 deadline.
