Walmart 2021 Sustainability Report

Becoming An Omni-Channel, Regenerative Company

Walmart has long taken a shared value, whole‑system approach to environmental, social and governance issues. The company aims to do more than operate responsibly and mitigate business risk—they want to fulfill their mission to become regenerative in a way that creates value for people and the planet. Their 2021 report outlines progress and investment made to further their sustainable ambitions.

Walmart is committed to 100% renewable electricity by 2035. In 2020, an estimated 36% of their global electricity needs were supplied by renewable sources.


In 2020, the company realigned their SBT to a 1.5 degree Celsius trajectory, the highest ambition approved by the Science Based Targets Initiative (SBTi).


Walmart’s new target is to reduce absolute scopes 1 and 2 GHG emissions by 35% by 2025 and by 65% by 2030 (2015 base year) on the way to achieving zero emissions in 2040.


They achieved a 12.1% reduction in scopes 1 and 2 emissions between the 2015 calendar year baseline and 2019.


The company achieved a 19% decrease in carbon intensity per revenue (FY2016–FY2020).


The company’s Project Gigaton™ initiative is part of their commitment to pursue substantial emissions avoidance and reduction in product supply chains.


More than 3,100 suppliers have formally signed on to Project Gigaton™, making it one of the largest private sector consortiums for climate action.


Walmart’s climate strategy includes adapting their operations to enhance resilience in the face of climate risk, such as: preparing their facilities and associates for weather‑related disasters, taking steps to enhance surety of supply, and accounting for transition risk in business planning.


Walmart made CDP’s ‘A List’ and Supplier Engagement Leaderboard for Climate for the second consecutive year in 2020.


Walmart has a board-adopted climate policy and advocates for 1.5 degree Celsius-aligned, science‑based national and international climate policies that are consistent with achieving net-zero emissions by 2050.


The company is committed to a movement to transition from a “take‑make‑dispose” approach to one that values the reuse and regeneration of materials.


Walmart set a goal to achieve zero waste to landfill or incineration in their U.S., Canada, Mexico, U.K., and Japan markets by 2025.


In the calendar year 2020, they diverted 81% of waste from landfills and incineration globally, holding steady from the previous year.


To reduce food waste in their operations, Walmart focuses on increasing the sell-through of food products and diverting unsold food from landfill, putting still-fresh food to use for meals in the community or other purposes.


Walmart is working with their suppliers and the broader retail consumer packaged goods industry to optimize packaging, with the overall ambition to accelerate a transition to 100% recyclable, reusable, or industrially compostable private brand packaging.


In FY2021 the company became a founding partner of Closed Loop Partners’ Beyond the Bag effort, working with retailers, NGOs and entrepreneurs to come up with industry wide solutions to increase circularity.


To encourage their customers to participate in the circular economy, Walmart launched a new partnership in 2020 with thredUP to provide new, like new, or gently used items from its inventory for sale on the Walmart website.


Walmart and the Walmart Foundation committed in 2020 to help protect, manage, or restore at least 50 million acres of land and 1 million square miles of ocean by 2030.


The retailer’s sourcing teams seek to procure products and ingredient lines that support their regenerative ambitions and advance their goals.


Commodities with certifications that support Walmart’s goals and commitments include palm oil, coffee, pulp and paper, farm-raised seafood, wild-caught seafood, cotton, bananas, and pineapples.


Walmart’s Acres for America program, administered by the National Fish and Wildlife Foundation (NFWF), has helped protect over 1.6 million acres since 2005.

Taking a step back and assessing our business and societal aspirations, we set a goal last fall to become a regenerative company—one that restores, renews and replenishes.

Doug McMillon

President and Chief Executive Officer

As a multicategory retailer operating in multiple countries, Walmart engages suppliers, customers, and NGOs in sustainability initiatives across a wide range of product supply chains. In addition to their own internal initiatives to reduce their footprint and contribute to a more circular economy, Walmart outwardly advocates by leading one of the largest private sector consortia for climate action—contributing to public policy, and engaging in thought leadership to inspire other businesses to create impact, too.
