It's important that we think about our ESG objectives holistically. Suppliers' qualifications will be important. Are they a responsible counterparty as well? We evaluate our suppliers on the same basis and are starting to more and more.
Refineries consume a lot of electricity and natural gas, so renewable natural gas is something we need on the front end to make that turn, as well as clean electricity. We are a big hydrogen producer. For our future investments, we will look at producing hydrogen that we call “greener”. I will not say “green”, because there are different definitions for blue, grey, green, etc.
Everything will have to have a lower carbon intensity in general—all the inputs into the refinery. Then, what goes out also has to be of a lower carbon intensity. We will use new technology inside the refinery to take, for example, the off-gasses from the refining process that are low carbon themselves—because they come from low-carbon raw materials—and burn that instead of higher carbon intensity alternative fuels.
Again, I go back to the virtuous cycle—
