A sample consumer basket shows that employing green fertilizer could reduce greenhouse-gas emissions from agricultural end products by about 5 percent.

Agriculture is one of the primary contributors to greenhouse-gas emissions (GHG) and climate change. Agriculture is responsible for about 24 percent of global emission, making agricultural emissions a major focus of decarbonization efforts. Unless addressed, emissions from agriculture production and land use are likely to grow by 15 to 20 percent by 2050.1 Limiting the impact of climate change to 1.5°C will be difficult without cutting agricultural emissions substantially.
