Support the adoption of low-carbon nitrogen fertilizers

As well as improving soil and nutrient management, governments can decarbonize agriculture by supporting the adoption of low-carbon nitrogen fertilizers, which are the heaviest emitters of all synthetic plant nutrition products. Solutions include nitrogen fertilizers from ammonia produced using renewables rather than the conventional pathway of using natural gas, though the price of green ammonia is two to three times that of gray ammonia. The use of nitrogen fertilizers made with green ammonia does not directly reduce on-farm emissions because they behave the same as gray. However, by incentivizing farmers to switch to low-carbon fertilizers, governments can reduce demand for gray products and thus the related manufacturing emissions. This demand can be bolstered by the introduction of financial incentives, agriculture subsidy reforms, mandates d carbon pricing on farmers.
