Integrating policy, market, and technology for sustainability governance of agriculture-based biofuel and bioeconomic development in the US

Abstract The scaled-up production of biofuels and bioproducts in the US is likely to cause land use expansion and intensification domestically and internationally, possibly leading to undesirable environmental and socioeconomic consequences. Although these concerns have been widely recognized, sustainability governance systems are yet to be developed. Here, we review (1) the US bioenergy policies, (2) biofuel production and market trends, (3) major sustainability concerns, and (4) existing regulations and programs for sustainability governance, including potential interactions with markets and technology. US bioenergy policy dates back to the 1970s and has evolved over time with various tax incentives plus production mandates in recent key legislation. Commercial production of cellulosic biofuels is impeded largely by technology and cost barriers. Uncertainties exist in the estimates of environmental and socioeconomic impacts due to the lack of empirical data and knowledge of complex relationships among biofuel and bioeconomic development, natural ecosystems, and socioeconomic dimensions. There are various existing sustainability governance mechanisms on which a biofuel sustainability governance system can be built on. Considering all these, we propose an adaptive system that incorporates regulations, certification, social norms, market, and technology for sustainability monitoring and governance, and is able to contribute to addressing the overall environmental concerns associated with collective land use for food, fiber, and fuel production. Building on existing programs and mechanisms and with proper monitoring of biofuel and bioproduct development, such a governing system can be developed and implemented in response to sustainability concerns that may arise as biofuel and bioproduct production increases.
