A new study shows how fertilizer emissions could drop 80 percent by 2050.

Popular Science – From methane in beef production to synthetic fertilizers, it’s no secret that agriculture is a huge source of climate-change inducing greenhouse gasses, and there’s a lot of work to be done in making our food systems climate-friendly.

Manure and synthetic fertilizers emit the equivalent of 2.6 gigatonnes of carbon annually, more than global shipping and aviation combined.

Reducing the amount of fertilizer used across the board would be the most effective way of reducing the emissions associated with them, including using water electrolysis during fertilizer production to keep methane from forming and using nitrogen inhibitors in the fertilizer when it is in the field.
