Project Gigaton

A Billion Tons of Sustainable Opportunity

Project Gigaton

Walmart recently announced Project Gigaton, its latest sustainability push to remove 1 billion metric tons of greenhouse gases (GHG) from its supply chain by 2030.

It’s an ambitious and laudable goal from a company that has worked to incorporate greater levels of sustainability into its operations since 2005.

It also signals an opportunity.

While working to reduce greenhouse gas emissions, Walmart suppliers can drive budget certainty and risk mitigation while potentially saving hundreds of millions of dollars on their own energy costs. In fact, the country’s largest energy users waste $80 billion in electricity and natural gas expenses every year.
