From an agricultural level, reducing carbon emissions can come from various practices like limited or no tillage, optimised fertiliser use/use of natural alternatives and crop rotation. All of these things can improve the biodiversity of the soil which in turn can sequester more carbon, preventing it from being released into the atmosphere. Measuring carbon capture also allows growers to receive carbon credits which they can then monetise. Switching diesel powered machinery with renewable power can reduce GHG emissions too.
