EDF worked with Walmart to set an aggressive goal: reduce climate-warming emissions from its supply chain by 20 million metric tons by 2015.

A large portion of this will come from using fertilizer more efficiently on our farmlands.

The fertilizer used to grow corn, wheat and other crops is one of the biggest climate pollution “hot spots” in Walmart’s entire supply chain. Nitrogen fertilizer releases a greenhouse gas that is 300 times more potent than carbon dioxide. A lot of this fertilizer is lost, and ends up polluting waterways and the atmosphere instead of helping crops grow.

Walmart's commitment requires that suppliers of products that use commodity grains – which includes everything from cereal to soda – develop plans to optimize fertilizer use on farms.

We project that our work with Walmart will reduce fertilizer use by up to 30% and cut 7 million metric tons of greenhouse gas emissions, all while protecting water quality and soil health. EDF will work closely with Walmart to make sure that its suppliers continue to meet these goals. EDF is also looking to extend our work to include other influential partners throughout the supply chain.
