Okay, good.
Biodiesel seems that it could be a quick way to change things so we reduce the overall emissions, but how close are we to scaling up? How difficult would it be to scale up in terms of having the feedstocks to buy...?
Where would we be by 2030? Can we do this by 2050 to convert all our diesel stocks to biodiesel? That's where we have to be by 2050.
