GDWF is a 501-c3 tax exempt foundation that mostly provides education and outreach services to those who are interested in replacing fossil-based (conventional) diesel fuel. We have more recently broadened our scope to include non-liquid fossil fuel replacements, mostly from renewable biomass. It is the sister organization of the Wisconsin Biodiesel (Trade) Association.
