Photocatalysis looks like a panacea to fight all potent greenhouse gases, as photocatalyzed reactions are able to transform or destroy almost all well-mixed, long-lived greenhouse gases – CO 2, CH 4, N 2 O, CFC-12 and CFC-11 – which account for about 96% of the direct radiative forcing, and also short-lived climate forcers like VOCs, NOx, BC and soot that have an important contribution to climate change.

So the correct answer is '60%,20%,14%,6%'. Answer verified by Toppr Photocatalysis looks like a panacea to fight all potent greenhouse gases, as photocatalyzed reactions are able to transform or destroy almost all well-mixed, long-lived greenhouse gases – CO 2, CH 4, N 2 O, CFC-12 and CFC-11 – which account for about 96% of the direct radiative forcing, and also short-lived climate forcers like VOCs, NOx, BC and soot that have an important contribution to climate change.

Global-scale trace-gas concentrations from prior to 1750 are assumed to be practically uninfluenced by human activities such as increasingly specialized agriculture, land clearing, and combustion of fossil fuels. The perturbation to direct climate forcing (also termed “radiative forcing”) that has the largest magnitude and the least scientific uncertainty is the forcing related to changes in the atmospheric global abundance of long-lived, well mixed greenhouse gases, in particular carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), and halogenated compounds (mainly CFCs).

CO2-CH4-N2O CFC-12 CFC-11 isotope data for CO2 and CH4. Since we are not refuting the validity of trace gas records from Law Dome, within the context of our manuscript, these publications add no additional information to the CO2, CH4, and N2O measurements (Etheridge et al., 1996 and 1998; MacFarling Meure et al., 2006). Effects of elevated atmospheric CO2 on CH4 and N2O emissions during the paddy rice-growing season were examined in a FACE (free-air carbon dioxide enrichment) study.

But CH 4 also absorbs much more energy than CO 2. The net effect of the shorter lifetime and higher energy absorption is reflected in the GWP. The CH 4 GWP also accounts for some indirect effects, such as the fact that CH 4 is a precursor to ozone, and ozone is itself a GHG. Nitrous Oxide (N 2 O) has a GWP 265–298 times that of CO 2 for a 100-year timescale.
