The U.S. EPA has published data on renewable identification numbers (RINs) generated in April. While no D3 cellulosic biofuel or D7 cellulosic diesel RINs were generated during the month, more than 28.22 million D5 advanced biofuel RINs were generated. Information published by the EPA also shows that nearly 179.29 D4 biomass-based diesel RINS and 1.08 billion D6 renewable fuel RINs were also generated in April.

During the first four months of 2013, more than 1.72 million D5 advanced biofuel RINs were generated for biogas. Approximately 474,638 of those RINs were generated in April, with about 526,641 generated in March, 361,346 generated in February, and 361,535 generated in January.

In addition, more than 157 million D5 advanced biofuel RINs were generated for ethanol production during the first four months of the year, along with nearly 3.91 million RINs for non-ester renewable diesel.

No D3 cellulosic biofuel RINs were generated during the first four months of the year. However, 8,332 D7 cellulosic diesel RINs were generated during the four-month timeframe, all in March.

The EPA data shows that more than 6.87 million assigned D5 advanced biofuel RINs are currently available, along with approximately 137.62 million separated D5 advanced biofuel RINs. Currently, there are no D3 cellulosic biofuel or D7 cellulosic diesel RINs available.

To date in 2013, nearly 12.71 D5 advanced biofuel RINs have been generated by domestic producers. The remaining 149.97 million D5 RINs were generated by importers.
