For a starting amount of 1 tonne of methane, which has a GWP of 25, after combustion there would be 2.74 tonnes of CO 2, each tonne of which has a GWP of 1. This is a net reduction of 22.26 tonnes of GWP, reducing the global warming effect by a ratio of 25:2.74 (approximately 9 times).

An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
The sharp acceleration in CO 2 emissions since 2000 to more than a 3% increase per year (more than 2 ppm per year) from 1.1% per year during the 1990s is attributable to the lapse of formerly declining trends in carbon intensity of both developing and developed nations. China was responsible for most of global growth in emissions during this ...
This is an accepted version of this page This is the latest accepted revision, reviewed on 24 January 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
The 2023 data represent the highest level recorded and experienced an increase of 1.9% or 994 Mt CO 2 eq compared to the levels in 2022. The majority of GHG emissions consisted of fossil CO 2 accounting for 73.7% of total emissions.
Global map of greenhouse gas (GHG) emissions, including agriculture and land use change, measured in carbon dioxide-equivalents over a 100-year timescale. [1] Annual GHG emissions by region, including agriculture and land use change, measured in carbon dioxide-equivalents over a 100-year timescale [2] Per capita annual GHG emissions, including agriculture and land use change, measured in ...
The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...
