Walmart has announced a significant milestone in its sustainability efforts, achieving its Project Gigaton goal six years ahead of schedule.
Launched in 2017, the initiative aimed to reduce, avoid, or sequester 1 billion metric tons of greenhouse gas emissions from the company's product value chain by 2030. However, through extensive collaboration with over 5,900 suppliers, Walmart has surpassed this ambitious target, marking a notable achievement in corporate environmental responsibility.
Walmart supported efforts on the supplier side by hosting best-practice summits, providing resources like the Circular Connector and Factory Energy Efficiency, and launching the Gigaton PPA program to facilitate renewable energy procurement. Suppliers were instrumental in implementing practices to reduce emissions across various aspects of their operations, from energy use to agricultural practices, said Kathleen McLaughlin, Executive Vice President and Chief Sustainability Officer at Walmart.
Project Gigaton emphasized the potential of collective action in the private sector to make significant environmental impacts. The initiative's achievement was guided by partnerships with scientific organizations and environmental groups, including the World Wildlife Fund (WWF), Environmental Defense Fund (EDF), World Resources Institute (WRI), and CDP.
Looking forward, Walmart is not resting on its laurels. The retail giant is setting its sights on broader sustainability goals, aiming for zero emissions by 2040. This includes enhancing estimates of its Scope 3 emissions footprint, identifying cost-effective interventions, and continuing to collaborate with suppliers to innovate and implement real-world solutions for emissions mitigation. Walmart's ongoing commitment to sustainability reflects a broader trend among global corporations recognizing the importance of environmental stewardship as integral to their business operations and long-term viability.
Several major retailers have launched ambitious sustainability programs similar to Walmart's Project Gigaton initiative. These programs often focus on reducing carbon footprints, enhancing renewable energy usage, minimizing waste, and promoting sustainable sourcing. Here's a look at similar sustainability efforts from leading global retailers:
Amazon’s Climate Pledge
Amazon co-founded The Climate Pledge in 2019, committing to reach net-zero carbon across its business by 2040, 10 years ahead of the Paris Agreement. The pledge now has signatories from numerous companies worldwide, committing to tangible, actionable sustainability and carbon reduction goals. Amazon also launched the Climate Pledge Fund, a $2 billion venture investment program to back companies developing products, services, and technologies to protect the planet.
IKEA’s People & Planet Positive
IKEA aims to become climate positive by 2030, reducing more greenhouse gas emissions than the IKEA value chain emits, while growing the IKEA business. This involves transitioning to renewable energy across all its operations, including using electric vehicles for home deliveries and installing solar panels on its stores. IKEA also focuses on circular principles, aiming to use only renewable or recycled materials in its products.
Target’s Sustainability Goals
Target has committed to reducing its greenhouse gas emissions by 30% by 2030 and aims to have 80% of its suppliers set science-based reduction targets on their Scope 1 and Scope 2 emissions by 2023. The retailer is also investing in renewable energy projects and enhancing its energy efficiency across all stores. Additionally, Target has pledged to send zero waste to landfill from its U.S. operations by 2030.
Unilever’s Sustainable Living Plan
Unilever aims to decouple its growth from its environmental footprint, while increasing its positive social impact. The plan includes improving health and well-being for more than 1 billion people, reducing environmental impact by half, and enhancing livelihoods for its millions of employees, suppliers, and retailers. Unilever is also moving towards 100% recyclable plastic packaging by 2025.
H&M Group’s Climate Positive by 2040
H&M Group aims to become climate positive throughout its entire value chain by 2040. This includes reducing more greenhouse gas emissions than its value chain emits, from raw material to final product. The company focuses on increasing the use of renewable energy in its supply chain, improving energy efficiency, and investing in carbon removal projects.
Nestlé’s Net Zero Roadmap
Nestlé has outlined a detailed plan to achieve net-zero greenhouse gas emissions by 2050. This includes sourcing 100% of its electricity from renewable sources within the shortest practical timescale, optimizing the use of water and improving water management, and increasing the number of 'carbon neutral' brands.
These initiatives reflect a growing trend among corporations to take responsibility for their environmental impact. By setting ambitious sustainability goals, these companies are not only contributing to the fight against climate change but also setting new standards for corporate environmental stewardship.
