Indeed, although palm nuts/oil as the result of clear-cutting is a straw man. I do agree, however, biodiesel is quite a varied product. There could be biodiesel made from palm or beef/meat byproducts (tallow), which could in theory come from a clear-cut area. But it would likely constitute a very small volume of biodiesel (compared to soy for example [1]). Soy ain’t perfect either (gmo, mono cropping etc etc) but certainly better than petroleum.

Edit/Note: I’m in the US and typically seek out data for the North American region. Maybe palm oil biodiesel is a bigger thing in other parts of the world (Africa, Europe, Asia?) - not sure. Would be intrigued if there is data supporting it either way. The US dataset below has “no data” explicitly stated for palm oils.
