The Section 45Z tax incentive is creating new opportunities for American farmers by increasing demand for crops grown with sustainable practices. Established under the Inflation Reduction Act of 2022, the 45Z Clean Fuel Production Credit rewards producers of low-carbon transportation fuels based on the greenhouse gas emissions associated with producing those fuels.
While the credit is claimed by fuel producers rather than farmers, agricultural operations play a critical role in helping biofuel manufacturers qualify for higher tax credits.
Unlike previous biofuel incentives that focused on specific fuel types, the 45Z tax credit uses a technology-neutral approach. The credit amount depends on the carbon intensity of the finished fuel.
Carbon intensity measures the total greenhouse gas emissions generated throughout the fuel's life cycle, including crop production, transportation, processing and distribution. The lower the carbon intensity score, the greater the potential tax credit for the fuel producer.
For farmers, this means that the way crops are grown can directly influence the value of the fuel produced from those crops. Agricultural practices that reduce greenhouse gas emissions can help lower the carbon intensity of corn, soybeans and other feedstocks used to produce ethanol, renewable diesel, biodiesel and sustainable aviation fuel.
Many conservation practices already adopted by farmers may contribute to lower carbon intensity scores. These include practicing reduced or no-till farming, planting cover crops, improving nutrient management, using precision agriculture technologies, and adopting more efficient irrigation and fuel management practices.
While specific accounting methods continue to evolve, these practices are expected to become increasingly valuable as clean-fuel markets mature.
As biofuel producers seek to maximize their 45Z tax credits, they are expected to place greater emphasis on sourcing feedstocks from farms that can document sustainable production methods. This could create premium pricing opportunities, preferred marketing agreements, or new contracts for farmers who maintain detailed production records and participate in conservation programs.
Good recordkeeping will become increasingly important. Farmers should document fertilizer applications, crop rotations, tillage practices, fuel usage, cover crop implementation and other management activities that may affect the carbon intensity of their crops. Accurate records can help verify sustainability practices and support participation in emerging low-carbon supply chains.
Changing the energy sector
The 45Z incentive also may strengthen rural economies by encouraging additional investment in ethanol plants, renewable diesel facilities and sustainable aviation fuel production. Increased demand for agricultural feedstocks can benefit local communities through expanded markets, job creation and infrastructure development while supporting America's growing renewable energy sector.
Although many implementation details continue to be refined by federal agencies, farmers do not need to wait to begin preparing. Investing in conservation practices, adopting precision agriculture technologies and improving operational efficiency can position farms to meet future market expectations while delivering agronomic and environmental benefits.
The 45Z tax incentive represents more than a policy change; it also signals a shift toward rewarding agricultural production that contributes to lower-carbon energy solutions. Farmers who embrace sustainable practices and maintain strong production records may be well positioned to benefit from new market opportunities as the clean fuels industry continues to grow.
By partnering with biofuel producers and focusing on measurable environmental outcomes, agriculture can play a leading role in building a more sustainable and profitable energy future.
