Climeworks reverses Climate Change with DAC+S Technology
Objective: The Mitigation of Climate Change
Which Sectors Generate the Most CO2 Emissions?
The largest share of total emissions is attributable to energy and electricity consumption in buildings (17.5 % of total emissions), industry (24.2 %) and transport (16.2 %). In particular, road transport (11.9 %), private households (10.9 %) and the iron and steel industry (7.2 %) are the main contributors. Energy consumption as a whole accounts for 73.2 % of total emissions. Another notable contributor is the food supply.
Agriculture and forestry account for 18.4 % of total emissions, and animal husbandry for 5.8 %. The food industry, including cultivation and use of land as well as refrigeration, the processing and transport of food, accounts for a total of 26 % of CO2 emissions.
CO2 Emissions Rise to All-time High in 2021
According to a study by the International Energy Agency (IEA), the total amount of CO2 emitted reached a new record high in 2021. With a total of 36.3 gigatons of CO2, emissions in 2021 more than offset the corona-related reduction in emissions in 2020. The trend of rising CO2 emissions will continue.
Energy Emissions Rise Across Virtually All Sectors
With the exception of the transport sector, CO2 emissions from electricity and heating, in industry, and from buildings have increased as a whole in 2020 and 2021. Energy consumption in these sectors accounts for 73 percent of total emissions.
The Use of Fossil Fuels is on the Rise
About 40 percent of global emissions come from burning coal. According to estimates by the Mercator Research Institute on Global Commons and Climate Research (MCC), there are barely 8 years left to curb fossil fuel emissions and limit global warming to 1.5 degrees Celsius.
