As global corporations scramble to meet net-zero targets, the battleground for climate action has shifted from internal operations to the sprawling, complex web of global supply chains. For many multinationals, "Scope 3" emissions—those generated by suppliers—account for the vast majority of their total carbon footprint. Consequently, supplier engagement programs have evolved from a "nice-to-have" initiative into a mission-critical pillar of corporate climate strategy.

Yet, a fundamental tension is brewing beneath the surface of these high-level commitments. While boardrooms tout decarbonization roadmaps, the entities responsible for executing those changes—the suppliers themselves—are voicing deep frustration. A recent survey of over 180 suppliers conducted by the Scope 3 Peer Group, a coalition of 4,000 sustainability professionals, reveals a stark reality: corporate rhetoric regarding climate action is often failing to meet the hard, cold reality of commercial procurement.

The Disconnect: A "Pour Your Heart Out" Moment

The impetus for this investigation was a simple, provocative question posed to suppliers by the Scope 3 Peer Group: "What do you most want customers to know about the reality of being a supplier asked to decarbonize?"

To encourage transparency, the peer group guaranteed anonymity. The result, according to Oliver Hurrey, the group’s founder and chair, was a deluge of candid feedback. "Pour your heart out," Hurrey had invited. Suppliers did exactly that. The responses, which paint a picture of misaligned incentives and bureaucratic fatigue, suggest that many large buyers are inadvertently sabotaging their own sustainability goals through a lack of internal coordination.

The Core Conflict: Sustainability Ambitions vs. Procurement Reality

The most prevalent grievance, cited by 43 percent of respondents, is the "price-performance paradox." Suppliers report a consistent pattern: a company’s sustainability team will approach them with rigorous decarbonization requirements, only for the procurement department to award contracts based solely on the lowest unit price.

"The suppliers are actually willing," Hurrey explains. "They’re basically saying you’re not giving us practical, consistent, or frankly believable commercial outputs."

This creates a "Jekyll and Hyde" experience for the supplier. On one hand, they are pushed to invest in renewable energy, low-carbon materials, and energy-efficient logistics. On the other, they are squeezed by procurement teams who seem entirely detached from the company’s environmental targets. As Hurrey summarizes the sentiment, "Once the sustainability team asks us to decarbonize, we do all this great stuff, and then we go to the commercial procurement team and they go, ‘What’s decarbonization?’"

Engineering Emissions: The Burden of Rigid Specifications

Beyond the commercial disconnect, there is the technical hurdle of product design. Nearly a quarter of the survey respondents highlighted that their customers’ own specifications often act as a barrier to emission reductions.

Many buyers mandate specific materials, components, or manufacturing processes that are carbon-intensive. If a supplier is contractually obligated to use a specific grade of steel or a particular chemical compound dictated by the client, their ability to innovate or pivot to lower-carbon alternatives is effectively shackled.

"Our customers usually specify what material to use and even which suppliers to use," one anonymous respondent noted. "If the customer wants us to decarbonize, these specifications need to align with the wish to decarbonize!"

What sellers really think about supplier engagement programs

This suggests that for many corporations, true decarbonization requires a radical rethink of procurement and design processes, moving away from rigid, legacy specifications that lock in high-carbon footprints for years to come.

The Administrative Tax: "More Reporting Than Doing"

Perhaps the most ironic finding of the survey concerns the administrative burden of sustainability reporting. Sustainability professionals at major firms frequently complain about the "alphabet soup" of reporting frameworks (CDP, TCFD, CSRD, etc.) they must navigate. However, the survey reveals that these same companies are imposing a similar—if not worse—burden on their own suppliers.

"We are overwhelmed with questionnaires," one supplier lamented. "The majority of time we receive no feedback or engagement as a result of our participation—only notices if we are delinquent."

The issue is one of fragmentation. Without a unified standard for data collection, suppliers are forced to respond to dozens of different questionnaires, each with its own methodology, reporting platform, and timeline. This creates a significant "resource tax," where the time and capital a supplier could spend on actual emission-reduction projects are instead diverted to filling out spreadsheets. When that data disappears into a black hole—with no feedback loop or guidance on how to improve—the entire exercise fosters resentment rather than progress.

Chronology of the Scope 3 Crisis

The current state of affairs is the result of several years of rapid evolution in corporate climate strategy:

  • 2015–2018 (The Era of Commitment): Companies began signing onto science-based targets, focusing primarily on Scope 1 and 2 emissions (direct operations and energy consumption).
  • 2019–2021 (The Scope 3 Realization): As Scope 1 and 2 targets were met or formalized, firms realized that up to 90 percent of their footprint lived in the supply chain. This triggered a wave of "supplier engagement" initiatives.
  • 2022–2023 (The Implementation Gap): Firms began rolling out mass questionnaires to suppliers. The sheer volume of these requests, combined with lack of technical support, led to "survey fatigue."
  • 2024–Present (The Call for Recalibration): Industry groups, such as the Scope 3 Peer Group, have begun to act as intermediaries, highlighting that without systemic alignment—between sustainability and procurement, and between buyers and sellers—decarbonization will stall.

Implications: A Call for Radical Partnership

The implications of this research are clear: current supplier engagement strategies are ripe for disruption. To bridge the gap, organizations must move beyond the "questionnaire-and-forget" model.

Better supplier engagement, according to the peer group’s findings, requires a shift toward:

  1. Commercial Integration: Sustainability metrics must be weighted alongside price in procurement decisions. If a low-carbon product is more expensive, there must be a mechanism to subsidize or share that cost, or a willingness to pay a "green premium."
  2. Collaborative R&D: Buyers should work with suppliers to redesign products, allowing for flexibility in material selection that favors lower carbon alternatives.
  3. Data Harmonization: Large buyers must collaborate to standardize reporting platforms. Reducing the administrative burden on suppliers is a prerequisite for meaningful data collection.
  4. Feedback Loops: Reporting should be a two-way street. Suppliers need to know how their data is being used and where they stand relative to industry benchmarks to encourage continuous improvement.

The Road Ahead

The findings from the Scope 3 Peer Group underscore a fundamental truth about modern business: sustainability cannot be a siloed department. It is an operational imperative that requires the total integration of commercial, engineering, and procurement functions.

As the industry prepares to convene for the Value Exchange Summit (taking place virtually from October 20 to 22), the conversation will shift from "how do we get data" to "how do we enable action." The suppliers have spoken; they are ready to decarbonize, but they are waiting for their customers to move from demand-based tactics to true, collaborative partnership.

The question remains: are corporate procurement teams ready to listen, or will they continue to prioritize the unit price over the planet? The transition to net-zero will not be won in the boardroom, but on the factory floor, and until the commercial incentives align with climate goals, the progress will remain, at best, incremental.
