All emissions in this figure and chapter refer to GtCO2e (gigatonnes or billion tonnes of carbon dioxide equivalent)-- the global warming potential - weighted sum of the six Kyoto greenhouse gases, that is, CO2, CH4, N2O, HFCs, PFCs and SF6, including LULUCF CO2 emissions.

Other gases that contribute to global warming — such as methane from waste — are converted into «carbon equivalent» units then added to the carbon footprint.

They compared estimated emissions for shale gas, conventional gas, coal (surface - mined and deep - mined) and diesel oil, taking into account direct emissions of CO2 during combustion, indirect emissions of CO2 necessary to develop and use the energy source and methane emissions, which were converted to equivalent value of CO2 for global warming potential.

An ambitious HFC agreement has the potential to avoid 100 billion CO2 - equivalent emissions by 2050 and 0.5 °C warming by 2100, significantly contributing towards the goals of the landmark Paris Agreement last year and eliminating the use of some of the most potent greenhouse gases in existence.

To put this into context, estimates of life - cycle global warming emissions for natural gas generated electricity are between 0.6 and 2 pounds of carbon dioxide equivalent per kilowatt - hour and estimates for coal - generated electricity are 1.4 and 3.6 pounds of carbon dioxide equivalent per kilowatt - hour [14].

This graph shows the equivalent amount of human induced global warming attributed to the different gases.

This time dependence of GHGs isn't fully accounted for in the standard IPCC equivalents, which are probably significant understatements of the total warming effect of a gas, if it's being emitted in the immediate future.

The equivalent carbon dioxide emission is obtained by multiplying the emission of a well mixed greenhouse gas by its Global Warming Potential for the given time horizon.

A global phase - down could avoid 1.1 — 1.7 billion metric tons CO2 equivalent (CO2 equivalent is a measure used to compare impacts of greenhouse gases based on their global warming potential in relation to CO2) of GHG emissions per year by 2030, with cumulative emission reductions of nearly 100 billion metric tons CO2 equivalent by 2050.

Even if natural gas combustion creates approaching 50 percent less CO2 equivalent per unit of energy produced, an amount which is well beyond best case on ghg emission reductions, it will not create the much greater emissions reductions necessary in the next 30 years to give any hope of limiting warming from exceeding levels that will cause catastrophic impacts.

Currently the non-CO2 greenhouse gases, taken together, add up to about 100 ppm of «CO2 equivalent» warming, and thus are significantly worsening the situation.

If warming prior to 1960 is 0.5 or greater, pretty much a given with the tropical reconstruction, Solar, aerosols, land use etc. can have have more impact than CO2 equivalent gases so your Half or complete baked explanation is going to need dLOD, fair dust and unicorns to get all the «consensus» players on the same page.

Climate sensitivity is usually defined to mean the amount of warming that the Earth will experience if atmospheric concentrations of CO2 reach 560 ppm of CO2 equivalent, where CO2 equivalent is the metric which translates other greenhouse gases into an equivalent level of CO2.

The Intergovernmental Panel on Climate Change (IPCC) estimates global anthropogenic greenhouse gas emissions for 1990 at 39.4 billion tonnes of carbon dioxide equivalent, suggesting that the Nigerian emissions may have represented approximately 0.09 % of the total in terms of CO2 and 0.76 % of the total in terms of methane, using the IPCCs 100 - year global warming potential for methane of 25.

Which is EXACTLY equivalent to the AGW argument: «More CO2 in the air causes «global warming» because it is a «greenhouse gas».»

Now to quantify their relative contribution to global warming, we need to find a way of putting all of these individual gases (and other climate drivers) on an equal — or equivalent — footing.

When referring to greenhouse gas emissions, «carbon dioxide equivalent» refers to the amount of carbon dioxide that would give the same warming effect as the effect of the greenhouse gas or greenhouse gases being emitted.
