Feedstock Category Practical Feedstock Availability ( million metric tons / year) Examples Sources: World Economic Forum (“WEF”) and McKinsey & Company’s Clean Skies for Tomorrow November 2020 Insight Report. Note: The WEF excludes unsustainable feedstock from its report (i.e. corn) as the indirect emissions from converting unsustainable feedstock into fuel largely offset the environmental benefit ( i.e. lower direct emissions).

Program Summary 32 ▪ Enacted by Congress in 2005, the RFS program establishes minimum renewable volumes to be blended into traditional petroleum - based fuel products ▪ To comply with the program, a refiner or importer of gasoline or diesel fuel must either blend renewable fuel into transportation fuel or obtain a credit (“Renewable Fuel Number” or “RIN”) to meet its Renewable Volume Obligation (“RVO”) ▪ Renewable fuel types are categorized by “D - Code” which fulfill different RVO categories. ▪ RVOs are established annually by the EPA and determine the percentage renewable blend threshold and corresponding RINs an obligated party must obtain for compliance ▪ RINs can be generated by blending renewable fuel products with petroleum - based fuels. Once generated, the blender can sell the RINs independently from the fuel product Renewable fuel created RINs generated Renewable fuel blended with non - renewable fuel Non - renewable fuel created or imported RVO incurred RINs are separating due to fuel binding Purchased RINs are retired to fulfill RVO Renewable Fuel Standard Volume Requirements (12/19/2019) Fuel Type (Bgal) 2017 2018 2019 2020 2021 Biomass - Based Diesel 2.00 2.10 2.10 2.43 2.43 Cellulosic Biofuel 0.31 0.29 0.42 0.59 N/A Advanced Biofuel 4.28 4.29 4.92 5.09 N/A Renewable Fuel 19.28 19.29 19.92 20.09 N/A Renewable Fuel Standard D - Codes and Obligation Standard Threshold Total Cellulosic Biomass - Advanced Renewable D - Code Biofuel Based Diesel Biofuel Fuel Cellulosic Biofuel 3 x x x Biomass - Based Diesel 4 x x x Advanced Biofuel 5 x x Renewable Fuel 6 x Cellulosic Diesel 7 x x x x RFS Overview Renewable Fuel Standards (“RFS”) Overview 32 Source: EPA, CARB, EIA.

Program Summary ▪ The Blenders Tax Credit (also called the “Biodiesel Tax Credit” or “BTC” ) currently provides qualified producers a tax credit of $1.00 per gallon when the required amount of biodiesel or renewable diesel is blended with petroleum diesel for use in trade or business ▪ The BTC acts to incentivize production and support revenue for qualified producers . The incentive must first be taken as a credit against the blender's fuel tax liability and any excess over this tax liability may be claimed as a direct payment from the Internal Revenue Service ▪ Initially enacted under the American Jobs Creation Act of 2004, Congress has extended or retroactively applied the program five times since 2011 ▪ Although currently set to expire in 2022, legislation introduced in both the House of Representatives and U.S. Senate on May 25, 2021 aims to extend the current blenders credit through 2025 (1) Program History 1.
