The following table lists the annual CO 2 emissions estimates (in kilotons of CO 2 per year) for the year 2023, as well as the change from the year 2000. [4] The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry.
The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry [n 2] Over the last 150 years, estimated cumulative emissions from land use and land-use change represent approximately one-third of total cumulative anthropogenic CO 2 emissions.

Biofuels are different from fossil fuels in regard to carbon emissions being short term, but are similar to fossil fuels in that biofuels contribute to air pollution. Raw biofuels burned to generate steam for heat and power, produces airborne carbon particulates , carbon monoxide and nitrous oxides . [ 19 ]
The indirect land use change impacts of biofuels, also known as ILUC or iLUC (pronounced as i-luck), relates to the unintended consequence of releasing more carbon emissions due to land-use changes around the world induced by the expansion of croplands for ethanol or biodiesel production in response to the increased global demand for biofuels ...
They are measured in carbon dioxide-equivalents over a 100-year timescale. The Intergovernmental Panel on Climate Change (IPCC) 6th assessment report finds that the "Agriculture, Forestry and Other Land Use (AFOLU)" sector on average, accounted for 13–21% of global total anthropogenic GHG emissions in the period 2010–2019.

The methanol used in most biodiesel production processes is made using fossil fuel inputs. However, there are sources of renewable methanol made using carbon dioxide or biomass as feedstock, making their production processes free of fossil fuels. [75] A by-product of the transesterification process is the production of glycerol. For every 1 ...
Emissions attributed to specific power stations around the world, color-coded by type of fuel used at the station. Lower half focuses on Europe and Asia [1]. This article is a list of locations and entities by greenhouse gas emissions, i.e. the greenhouse gas emissions from companies, activities, and countries on Earth which cause climate change.
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
