EPA released RIN generation data for December 2016, reporting that more than 1.8 billion RINs were generated during the month. More than 16.8 million D3 cellulosic biofuel RINs were generated in December, bringing the total for 2016 to 178 million, including 3.8 million D3 RINs for ethanol, 66.8 million for renewable liquefied natural gas, and 107.5 million for renewable compressed natural gas. Of the 178 million RINs, nearly 160 million were generated by domestic producers, and nearly 19.2 million were generated by importers.

More than 524 million D4 biomass-based diesel RINs were generated in December, resulting in a total of nearly 4.0 billion for 2016. The majority of RINs (3.28 billion) were generated for biodiesel, with 715 million for non-ester renewable diesel. More than 2.85 billion RINs were generated by domestic producers, with 830 million generated by importers.

For D5 advanced biofuel, 6.0 million RINs were generated in December, which brought the total for 2016 to 97 million. Ethanol accounted for the majority of RINs generated, nearly 61.3 million, with nearly 26.3 million generated for naptha, 1.54 million generated for heating oil, and 7.93 million generated for non-ester renewable diesel. Of the 97 million RINs, 62.6 million were generated by domestic producers, 34.4 million were generated by importers, and 312 million were generated by foreign entities.

Nearly 1.30 billion RINs were generated for D6 renewable fuel in December, resulting in a total of nearly 15.2 billion for 2016. The majority of RINs (14.7 billion) were generated for ethanol, with 169 million generated for biodiesel, and 281 million generated for non-ester renewable diesel. More than 14.7 billion RINs were generated by domestic producers, with 179 million generated by importers, and 281 generated by foreign entities.

The data indicates that no D7 cellulosic RINs were generated in December. In 2017, a total of 534,429 cellulosic RINs were generated for cellulosic heating oil. All of the D7 RINs were generated by importers.
