Are companies serious?

What you are referring to is scope 3 emissions; the emissions that come from the use of the product a company sells. Clearly not something Shell has much control over. One Dutch company could reduce production but it’s not going to do anything about the total amount of petroleum consumed in the world. If it’s not Shell it’s Exxon, Petrobras, Petrochina, Lukoil, etc. that will fill in the gap.

Shell has a goal of reducing scope 1 and 2 emissions. That’s the emissions created in the production process (1) and the emissions generated by the electricity they use (2). Shell, as a Dutch company is required to disclose their emissions under a specific audited methodology. So it’s possible they could misreport but it’s not that easy and there are repercussions if caught.

The only thing that will significantly reduce the use of oil and gas is the conversion to electric vehicles and the elimination of natural gas power plants.
