Analyst Insight: Reducing carbon emissions is a top priority, highlighting the urgent need for businesses to decarbonize their supply chains. To succeed, companies must prioritize accurate primary supplier data, embrace advanced technologies for better reporting, and collaborate across supply chains to implement effective sustainability strategies.

In February, the Climate Change Committee (CCC) published its recommendations for the Seventh Carbon Budget, covering 2038-2042. According to the CCC, to stay on track for net-zero emissions by 2050, the U.K. must achieve an 87% emissions reduction by 2040, based on 2019 levels.

For businesses, this underscores the urgent need to decarbonize their supply chains — one of the most complex sustainability challenges. Most emissions will fall under Scope 3, which includes indirect emissions from suppliers, logistics and end consumers. These emissions are difficult to measure and manage, making effective reduction strategies essential.

A Need for Primary Emissions Data

While Scope 1 and 2 emissions (those from direct operations, or indirect through the source of purchased energy) are relatively straightforward to track, Scope 3 emissions are far more complex, often making up the majority of an organization’s carbon footprint. Many businesses rely on estimates rather than accurate supplier data, leading to unreliable reporting and an unclear understanding of their environmental impact. Without precise Scope 3 data, businesses cannot effectively track decarbonization progress or meet emissions-reduction targets. Transitioning to primary supplier data — rather than secondary estimates — will be critical for improving accuracy and enabling better decision-making.

Global supply chains involve multiple suppliers operating under different regulatory environments, carbon accounting standards, and emissions-measurement methods. These inconsistencies make data access and verification difficult, complicating compliance and weakening businesses’ sustainability initiatives. Moreover, a single supplier’s failure to meet environmental standards can have cascading reputational consequences across the supply chain.

Despite these challenges, advanced technologies such as artificial intelligence-driven tools and data analytics platforms can help. These tools enable organizations to collect real-time, verifiable data from suppliers, improving reporting accuracy and compliance tracking. By prioritizing primary supplier data over secondary estimates, businesses can gain deeper insights into their Scope 3 emissions and implement more targeted, effective strategies to decarbonize their supply chain.

Sustainability and Supplier Selection

Supplier data is only valuable if it’s accurate and reflects meaningful sustainability progress. To drive real impact, businesses must embed sustainability into all procurement decisions, from supplier selection to contract catalogs. By prioritizing suppliers who are making tangible progress on their sustainability agenda and can provide accurate emissions data, businesses can reduce overall emissions and foster stronger, collaborative relationships. 

Suppliers should be segmented based on their data maturity and emissions capabilities. High-maturity suppliers can often provide verified data across Scopes 1, 2, and 3, along with product carbon footprints (PCFs). Medium-maturity suppliers might need additional support to implement data standards. Finally, low-maturity suppliers, such as those new to emissions tracking, often benefit from educational resources, tailored training sessions or incremental steps toward transparency. 

This segmentation helps companies target resources effectively, focusing advanced data requests on capable suppliers while educating and supporting others to build a collective momentum toward emissions reduction through training and development sessions.

Aligning on Protocols

The absence of standardized reporting frameworks leads to operational inefficiencies, forcing organizations to navigate multiple audits, overlapping certifications, and inconsistent compliance frameworks across industries and regions. Without harmonization, meaningful environmental progress remains difficult.

To address this, organizations should advocate for and adopt sustainability standards that are both industry-wide and applicable across multiple jurisdictions and markets. Aligning on common metrics and reporting protocols simplifies compliance, enhances visibility, and strengthens accountability across regions and the entire supply chain.

One of the most effective ways to unify sustainability efforts is through vertical coalitions — collaborative partnerships spanning the supply chain, from raw-material suppliers to end-product manufacturers. These coalitions enable data sharing, resource pooling, and best practice exchange, creating a cohesive strategy that addresses environmental impact at every stage. They also help organizations engage regulators collectively, shaping realistic and effective environmental policies.

Addressing supply chain sustainability challenges requires a strategic, data-driven, and collaborative approach. By improving emissions data accuracy, segmenting suppliers based on data maturity, embedding sustainability into procurement, and advocating for industry-wide standards, businesses can drive tangible progress in reducing their Scope 3 emissions. The time to act is now — companies that proactively address these challenges will be better positioned for long-term success in an increasingly decarbonized economy.
