If you had the same question about the headline that I did:

Renewable diesel is the term given to a biomass-based fuel that is chemically equivalent to petroleum diesel. This means it can be transported directly in petroleum pipelines or sold at retail stations without any infrastructure modifications or fuel blending.

Renewable diesel can be made from vegetable oil, animal fats, used cooking oil or even algae.

I don't feel great about this. I guess it technically counts as renewable, but aren't we still burning and expelling carbon into the atmosphere?
