Walmart reported that its businesses’ greenhouse gas emissions climbed by 3.9% in 2023. This reflects the fact that Walmart misses its latest emissions reduction goal, as the company attributed this increase to ageing refrigeration equipment, an expanded transportation footprint, and business development. Walmart’s 2025 and 2030 carbon reduction goals are now in jeopardy due to these issues.

Walmart had initially promised to cut Scope 1 and 2 emissions by 35% by 2025 and 65% by 2030. Cumulative reductions to Scope 1 and 2 emissions are still at 19.3%, falling short of the trajectory required to fulfil these targets, even though the company has reduced the intensity of its emissions per million dollars of revenue by 45% since 2015.

Key Barriers to Emissions Reductions

Walmart determined that three main factors caused its incapacity to reduce emissions more quickly:

• Refrigeration Equipment: Nearly 55% of the company’s Scope 1 and 2 emissions come from high-emitting, ageing refrigeration equipment.
• Transportation Footprint: Almost 25% of the fleet’s emissions are attributable to transportation, which has grown as a result of some fleet functions being moved in-house.
• Purchasing Renewable Energy: Although renewable energy sources account for 48% of Walmart’s operating load, development has stagnated. Between 2020 and 2023, the corporation inked power purchase agreements for more than 2 gigawatts of capacity, with plans to add 10 more by the end of the decade.

Walmart also mentioned the lack of clarity surrounding market incentives and laws, which could hinder the adoption of renewable energy projects and low-carbon technology.

Progress with Project Gigaton

Walmart’s Project Gigaton effort has shown success even though it does not typically publish Scope 3 emissions. Through initiatives including packaging reductions and plant efficiency enhancements, this program encourages suppliers to reduce greenhouse gas emissions. Walmart accomplished the initiative’s first target of cutting 1 billion metric tonnes of carbon from its supply chain earlier this year.

Despite these efforts, Walmart misses its latest emissions reduction goal, emphasizing the challenges the company faces in meeting its sustainability targets. Walmart continues to increase its supplier participation to increase the impact of its sustainability initiatives, with over 3,500 suppliers—representing 77 per cent of U.S. sales—participating.
