Emissions, Efficiency & Electricity: WalMart's Green Journey

Global retailer Walmart is accelerating its energy transition as part of a 2040 decarbonisation roadmap, embedding renewables into its logistics operations to reshape emissions management and energy resilience.

After acknowledging last year that its 2025 and 2030 net zero goals would not be met, Walmart has recalibrated its strategy to focus on accelerated renewable energy integration and electrification across its value chain.

Businesses advancing their decarbonisation efforts through low-carbon energy solutions are reaping tangible benefits in cost efficiency, operational continuity and brand perception.

Walmart is among the global players demonstrating that sustained progress in logistics energy transition can redefine corporate sustainability.

Powering a cleaner value chain

Walmart’s decarbonisation pathway is rooted in four strategic pillars: strengthening energy resilience, fostering innovation, building trust and managing affordability.

Its approach combines responsible sourcing and low-carbon logistics with investments in clean power sourcing, energy storage and electrification.

Operating across 19 countries, Walmart is strengthening grid reliability through a detailed energy and climate framework that promotes renewables uptake and sustainable land management.

In its FY25 ESG report, Walmart disclosed:

• 48.5% of its global electricity demand is met through renewable energy

• Scope 1 and 2 emissions are 18.1% below the 2015 baseline

• 82.6% of private brand packaging is recyclable

• 83.5% of operational waste is diverted from landfill and incineration

• 1.19bn TCO₂e has been avoided, reduced or sequestered in value chains since 2017

Even with these advances, the company expects further delays in reaching its 2025 and 2030 emissions goals, underscoring the complexity of scaling renewable energy infrastructure to meet global operational demand.

"Progress is not always straightforward or linear," explains Kathleen McLaughlin, Executive Vice President and Chief Sustainability Officer at Walmart.

"It requires partnership across sectors, industries and communities among groups with different perspectives and priorities. We often encounter gaps or barriers that require innovation in technology, infrastructure, or policy," she adds.

"But with collaboration, creativity and tenacity, we can facilitate positive, lasting improvements for our business and for society over time."

Navigating energy challenges

Walmart’s 2024 operations recorded a 3.7% year-on-year decrease in emissions intensity, but an 11.1% rise in operational emissions, reflecting the complexities of scaling low-carbon energy solutions across expanding logistics networks.

The company attributes this to higher energy demand in the US, Mexico and Central America, alongside lower renewable output.

It notes that “operational emissions progress will continue to be uneven year over year” given global energy infrastructure constraints and the pace of technology development in low-carbon heavy transport.

It continues to anticipate delays in achieving its interim targets of a 35% reduction by 2025 and a 65% reduction by 2030.

Through an expanding portfolio of solar and wind facilities, Walmart is advancing toward its goal of powering 100% of its operations with renewable energy by 2035. This initiative forms the foundation for achieving zero Scope 1 and Scope 2 emissions by 2040.

Investing in electrification and resilience

Electrification is central to Walmart’s decarbonisation progress. Transitioning its HGV fleet to electric models not only shields the company from volatile fuel markets and potential carbon taxes but enhances long-term operational predictability.

By embedding renewable energy solutions throughout its logistics network, Walmart is also reducing exposure to global energy price shocks that can erode retail margins. The company’s continuous investment in energy transformation underscores how decarbonisation and profitability can align through innovation and scale.

Its detailed ESG disclosures further reinforce transparency across the energy and supply chain ecosystem, enabling suppliers and partners to align with its low-carbon objectives.

While progress toward a fully zero-emission logistics network remains gradual, Walmart’s commitment to transforming its energy mix signals a decisive shift in how corporate supply chains are powered for the future.
