Renewable Fuel Standard Improvement Act - Amends the Clean Air Act to: (1) include the Secretaries of Agriculture and Energy in renewable fuel program activities under such Act; (2) revise the definition of "lifecycle greenhouse gas emissions" to base the measurement of such emissions on recent observable data and consideration of regional differences of renewable fuel production, rather than on indirect land use changes; and (3) expand the definition of "renewable biomass."
