Boeing and PetroChina, together with representatives of the Chinese energy sector and the global aviation industry, signed an agreement to evaluate establishing a sustainable aviation biofuels industry in China. The strategic assessment will take a comprehensive look at the environmental and socioeconomic benefits of developing sustainable alternatives to fossil-based jet fuels. The project will look at all phases of sustainable aviation biofuel development including agronomy, energy inputs and outputs, life-cycle emissions analysis, infrastructure, and government policy support. The assessment, slated to begin in June, supports a broader sustainable aviation biofuel agreement between China's National Energy Administration and the U.S. Trade and Development Agency to promote the commercialization and use of aviation biofuels in China through the U.S.-China Energy Cooperation Program. Other U.S. companies participating include AECOM, Honeywell's UOP, and United Technologies.
