> Are consumers not responsible for the carbon they emit through the gas they buy

Sure we are responsible, but it's not our choice that this gas is emitted... we aren't the ones responsible to make the choice toward theses combustibles on the planes sadly.

Shifting it over the ones that actually have control over whether they use more or less gas, is a great way to incentive them to go toward the one that use less gas, as they only want the cheaper options, not the best options.

At the end of the day, we are still paying for it, but the one that do have the power to change it, now is the one that see it over their balance sheet.
