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).

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 ...
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 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 ...
Carbon emissions per capita, 2020 Carbon emissions per 1000 square miles, 2020. This is a list of U.S. states and territories by carbon dioxide emissions for energy use, [1] [2] as well as per capita [3] [4] and by area.
World map of emission intensity (kg of CO 2 per Intl$), 2018. The following list of countries by carbon intensity of GDP sorts countries by their emission intensity.Carbon intensity or emission intensity of GDP is a measure that evaluates the amount of carbon dioxide (CO 2) emissions produced per unit of GDP.
New buildings must now limit upfront embodied emission intensity — emissions associated with manufacturing, transporting, and constructing major structural and envelope systems — to below 350 kg CO2e/m2." [23] The new requirements are currently voluntary for non-city-owned buildings.
