| Comment | Which has a higher GWP? On the one hand, venting gasses are over 80% methane, which has a 20 year GWP that is 84 times higher than that of CO2. Because there is no combustion, fewer toxic air contaminants (TAC) are created. However, methane increases tropospheric ozone which is toxic to the respiratory system. In contrast, TAC co-pollutants are created by combustion during flaring. These include PM, black carbon, and nitrogen oxides - each of which has a higher GWP than that of CH4. (CO2 emitted can be toxic and has a GWP of 1.) When the GWP of these TACs is added up, is the GWP of the cocktail higher than that of CH4 from venting? Thanks, David |
