2015 witnessed significant achievements in the transition to a low-carbon economy. Last December, more than 180 countries in Paris reached a historic agreement to jointly reduce greenhouse gas emissions. There are also 20 **initiatives that have announced innovative missions aimed at doubling clean energy research and development over the next five years. Some clean energy technologies have already become cost-competitive, and the existing technologies and costs will remain so. In terms of biogas, 2015 was a good year, especially compared to previous years. Due to the recent initiatives and trends, I truly hope 2016 will be better. In the summer of 2014, the U.S. Department of Agriculture released a strategic roadmap for biogas. The release of this roadmap marked the first time that federal agencies made a public commitment to coordinate efforts aimed at advancing the deployment of biogas systems across the United States. By the end of 2015, the U.S. Department of Agriculture published a report on the progress toward the goals set out in the roadmap. According to the progress report, the U.S. Department of Agriculture, the U.S. Department of Energy, and the U.S. Environmental Protection Agency have all identified and implemented policies to increase access to resources for biogas projects. The progress report also highlights technical achievements, various efforts by the private sector, and the identification of obstacles to be addressed in the future. Cooperation and coordination among federal agencies are crucial, as there is still much work to be done to truly scale up biogas resources on a larger scale. According to the 2014 Biogas Strategic Roadmap, the United States has over 2,000 sites that produce biogas, but at least another 11,000 sites support biogas systems. Although 2015 was a good year for biogas, it is clear that there is still much more we can and should do to make full use of its potential resource advantages. In 2015, biogas power generation experienced explosive growth under the Federal Renewable Fuel Standard (RFS). In July 2014, the U.S. Environmental Protection Agency revised its procedural rules to allow biogas generated from biogas treatment facilities, landfills, and agricultural producers to qualify as a feedstock for cellulosic fuels when the biogas is purified and upgraded for use as a transportation fuel. From January to November, over 112 million gallons of cellulosic fuel were reported to the EPA, 98% of which came from renewable compressed and liquefied natural gas. The transport fuel market provides producers with an attractive option for utilizing biogas. Under the Renewable Fuel Standard (RFS), project producers can sell biogas fuel credits at a premium of over $1 per gallon. Eligible biogas producers can also accumulate RFS renewable fuel credits, as stipulated by California’s Low-Carbon Fuel Standard program. From the first quarter of 2011 to the third quarter of 2015, the biogas credit value used for the low-carbon fuel standard program rose to nearly 10%. In 2016, I hope to see continued growth in the use of biogas as a fuel for transportation. As a renewable and low-carbon source, biogas serves as a complement to local strategies aimed at replacing natural gas or electricity in heavy-duty fleets. The biogas industry has made steady progress over the past few years. The industry reached a turning point in 2015, and I bet 2016 will be an even better year.
