new technologies. Many participants noted that to ensure the sustainability of these new fuels, economic incentives will also need to be provided to farmers and developers to use a systems approach—addressing soil, water, and air quality; carbon sequestration; wildlife habitat; and rural development. As it is expected to take at least until 2030 to attain large-scale cellulosic fuel production, most participants agreed that meeting this goal will require the building of tens to hundreds of conversion plants, as well as associated transport and distribution infrastructure facilities.
