@AdamJ "...That is statistically significant..."
6.8% of which total? Certainly not 6.8% of 'The Total Problem' ™.
And yet... There are some actual double-digit % of *all* global warming gas emissions that are low hanging fruit, and yet strangely untouched...
How about we institute carbon capture *just* (nowhere else) at all concrete factories? Such factories are almost always right next to railroad tracks, so the CO2 could be carried away by rail and fed into greenhouses for food, or algae farms to make fuel, or pumped underground for long term storage. Such an approach would result in concrete production changing to a net sucker-in of atmospheric CO2 as it ages.
How about we stop burning off methane from oil wells?
How about we ask Saudi Arabia to not run a 4-foot diamete oil pipeline over to Yeman or Oman to smelt Aluminium using fossil fuel? How about we mandate all Aluminium smelting shall occur ONLY in Iceland.
How about we run some power lines from Iceland to somewhere that people actually live?
How about we fix cow farts with dietary change?
How about someone fix the smoke-belching bunker-C powered ships that emit oxides of nitrogen that are aabout 'a quadrillion' (not really) times worse than CO2?
We humans need to switch from making promises we can't keep (Kyoto) and making trivial window-dresssing greenwash changes that don't matter at all... ...to taking actual easy, simple, cheap and effective changes that could knock 20-30% off 'The Actual Total' ™ with essentially no down-sides.
