Marks and Spencer has unveiled a major new initiative designed to reduce emissions across its international fashion supply chain, deepening its commitment to reaching net zero and strengthening supplier capacity to adopt clean energy solutions. The programme, called RE:Spark, was developed in partnership with Schneider Electric and aims to address the emissions hotspots that account for the overwhelming majority of the retailer’s climate footprint. As the apparel industry faces mounting scrutiny for its environmental impacts, the move raises an important question. Can collaborative, supplier-focused programmes meaningfully cut emissions in complex global supply chains, or will operational and financial constraints slow progress.

Positioning RE:Spark at the Center of M&S’s Net Zero Strategy

The new programme directly supports the company’s Plan A sustainability strategy, which includes a net zero target for 2040 and a commitment to significantly reduce Scope 1, 2 and 3 emissions by 2030. Scope 3 emissions make up roughly ninety five percent of M&S’s total footprint, with most originating from the production of goods in its Food and Fashion, Home and Beauty ranges. By focusing initially on high impact regions of its garment supply chain, M&S aims to create a model that can expand globally over the next three years. The company views RE:Spark not only as a mechanism to cut emissions but also as a structured way to modernise its supplier network, improve data quality and build long term resilience.

A Digital Hub for Data, Support and Renewable Energy Adoption

At the core of the initiative is a centralised digital platform where suppliers will be able to upload emissions data, monitor their decarbonisation progress and access guidance on renewable energy procurement. The platform will include tailored learning modules, regional market briefs and webinars, as well as advisory services to help suppliers assess the financial and technical feasibility of clean energy projects. A key feature of RE:Spark is its role in helping suppliers pool demand for renewable electricity through power purchase agreements. For many garment manufacturers, especially small and medium sized firms, navigating local energy markets or securing competitive renewable energy pricing can be difficult. Aggregated procurement aims to reduce these barriers and create economies of scale.

A Collaborative Model Designed to Unlock Supplier Action

Katharine Beacham, Head of Sustainability and Materials for M&S’s Fashion, Home and Beauty division, emphasised that collaboration is essential for delivering tangible change. She described RE:Spark as a mechanism for sparking new ideas, connecting suppliers with expertise and simplifying the path to renewable energy. Her comments reflect a growing understanding across the apparel industry that top-down sustainability strategies are insufficient without direct supplier engagement and on the ground support. M&S sees its role as facilitator rather than enforcer. By strengthening supplier networks and building shared knowledge, the company aims to catalyse broader industry transformation rather than isolated improvements limited to its own supply chain.

Schneider Electric Brings Technical Expertise to Address Adoption Barriers

Schneider Electric’s involvement adds a layer of technical and market expertise that is crucial for success. The company will support suppliers through energy assessments, renewable procurement strategies and implementation planning. Executive Vice President Steve Wilhite highlighted that many suppliers face structural barriers that limit their ability to shift to renewable power. RE:Spark is designed to close those gaps and accelerate the overall industry transition. Schneider Electric has played similar roles in supporting large corporates on emissions reduction, particularly in helping supply chains navigate fragmented energy markets. Their partnership with M&S signals a growing trend of retailers partnering with specialised energy firms to unlock decarbonisation at scale.

Why Fashion Supply Chain Emissions Are Hard to Tackle?

Fashion supply chains are complex, multi-tiered and geographically dispersed. Production spans fabric mills, dye houses, cut-and-sew factories and logistics corridors, each operating within different regulatory environments and energy infrastructures. Many facilities rely on coal or oil based thermal energy, making renewable adoption both technically challenging and capital intensive. RE:Spark aims to overcome these challenges by providing data tools, technical guidance and shared procurement pathways that lower the cost and complexity for suppliers. The programme will also help M&S improve visibility across its supply chain, a critical requirement for accurately measuring progress against Scope 3 targets.

Setting a New Standard for Supply Chain Decarbonisation in Retail

As regulation, investor pressure and consumer expectations converge, retailers are being pushed to demonstrate credible, science based climate action. M&S’s approach, which blends data transparency, supplier support and renewable energy access, offers a template that could influence the wider fashion industry. If successful, RE:Spark could become a model for how manufacturers and retailers collaborate to unlock decarbonisation at scale. Its expansion plan suggests that M&S is preparing for a multi year journey, aligning supplier transformation with long term commercial and sustainability goals.

A Sector Ready for Transformation if Tools and Incentives Align

M&S’s new initiative arrives at a moment when apparel supply chains face both increasing risk and unprecedented opportunity. Energy costs, extreme weather and regulatory changes make inaction costly, while emerging renewable technologies offer new routes to resilience. By anchoring its approach in collaboration and practical support, M&S is positioning itself to move the needle on the most difficult part of its climate footprint. The next phase will show whether suppliers, technology partners and retailers can work in sync to deliver meaningful emissions reductions. If they do, RE:Spark could become a catalyst for a broader shift across the fashion sector toward cleaner, more resilient manufacturing systems.
