In Washington, Engine Technology Forum has released the white paper Benefits of Renewable Bio-Based Diesel Fuels developed by Transport Energy Strategies, a leading consultancy on global transport energy issues. Renewable biobased fuels, such as biodiesel and renewable diesel, are a proven and available strategy for immediately reducing greenhouse gas and other emissions. This is true in both new, and existing, diesel engines across all applications. The paper provides a foundation of information about biobased diesel fuels, their production, consumption, future growth, and volume potential. It also includes approved uses, benefits and acceptance by diesel engine and equipment makers. The paper also discusses key policy considerations for maximizing the benefits from these fuels.
