Scope 3 - Moving from strategy to action to deliver value

The conventional view is that Scope 3 is merely a reporting burden or an abstract, distant ambition. However, companies should frame Scope 3 ambitions as a commercial imperative they have publicly committed to through milestone-driven reduction targets — e.g., significant cuts by 2030 as near-term goals, deeper reductions toward 2040 in some sectors, and net-zero across the value chain by 2050. 

Although these public pledges create accountability pressure, many companies treat them as checkboxes rather than opportunities for value creation. This article outlines practical actions leaders are taking to turn these targets from aspirational statements into operational reality and financial outperformance. 

Scope 3 surging ahead, despite occasional setbacks 

There is no doubt that a profound shift has occurred in the world of sustainability. Following COVID-19, sustainability initiatives exploded. Companies raced to commit to net zero goals and proclaimed them loudly, with a roughly 400% increase in firms pledging under the Science Based Targets initiative (SBTi) between 2020 and 2022. However, in recent years, sustainability has become a harder sell. 

Strong anti-sustainability signals in some regions — exemplified by the US administration's rollback of green policies following the 2024 re-election — have rippled globally. Terms like "net zero" and "decarbonization" are increasingly politicised. Coupled with slowing economies and intense cost-of-living pressures, this dynamic is playing out in boardrooms and markets alike. 

Yet the data tells a more nuanced story. While some high-profile retreats —such as BP abandoning absolute Scope 3 targets in its 2025 strategy reset — grab headlines, overall momentum is accelerating. The SBTi Trend Tracker 2025 shows that near-term science-based targets grew by 97%, and companies setting both near-term and net-zero targets surged by 227% from end-2023 to mid-2025, with nearly 11,000 companies now committed or validated — covering over 40% of global market capitalisation. 

Scope 3 emissions — typically comprising 70-90% of a company's total footprint — remain the hardest to tackle due to perceived difficulties with supply chain dependencies, in contrast, to how organisations tackle cost, quality and delivery within their supply chains demonstrating Scope 3 is not an insurmountable task.  Progress has stalled for many amid complexity and external pressures, but forward-thinking leaders aren't retreating. They're reframing Scope 3 as a source of competitive advantage. Chief Sustainability Officers (CSOs) and Chief Procurement Officers (CPOs) persist with a pragmatic approach: Scope 3 decarbonization gains traction only when it delivers clear business value (cost savings, innovation, market access) and demonstrable progress to sustain momentum and combat fatigue. 

Reframing Scope 3: From reporting challenge to commercial imperative 

Reporting Scope 3 emissions posed the initial challenge for most businesses, demanding complex data collection across vast supply chains. From baselining, 96% of SBTi-committed firms found that Scope 3 accounted for 70-90% of emissions — embedded in global energy, materials, and logistics supply chains, the same drivers of input and cost volatility. Yet Scope 3 has evolved beyond reporting. It is now frequently enshrined in publicly stated, milestone-bound reduction targets. Under frameworks like the SBTi Corporate Net-Zero Standard, companies commit to near-term reductions — often halving emissions or achieving substantial cuts by 2030 — interim progress, and long-term net-zero by 2050, or earlier — such as 2040 in the power sector. Scope 3 targets typically require coverage of material sources — at least 67% of them in near-term targets if they are responsible for more than 40% of total emissions, and at least 90% in long-term targets. These commitments — now held by thousands of companies representing major market cap — are visible to investors, regulators, customers, and stakeholders, amplifying scrutiny and reputational risk if progress lags. 

This makes Scope 3 not just an environmental issue, but a prime source of business vulnerability. Ignoring it — or treating targets as mere PR — creates escalating risks: 

• Margin risk from carbon pricing and material transitions: As carbon prices rise via emissions trading schemes, taxes, or border adjustments, suppliers pass through costs of carbon-intensive processes, exacerbated by highly volatile heat and power costs driven by volatile globally traded gas prices, inflating input prices faster than companies can adjust customer pricing—eroding margins. For example, on January 1, 2026, the EU's Carbon Border Adjustment Mechanism (CBAM) entered its definitive regime. Importers of high-carbon steel now face additional costs of €40–€60 per tonne at current EUA prices (~€90), while aluminium importers could shoulder liabilities nearing €500 million annually across sectors. As more countries adopt similar measures, carbon performance directly determines competitiveness. 

• Supply chain disruption risk: Scope 3 emissions span uncontrollable actors like suppliers, logistics providers, and downstream users. When these face carbon costs, regulations, or data gaps, ripples cause procurement delays, inconsistent inputs, and interruptions. Sphera’s 2026 Scope 3 report found that 45% of companies across 15 industries lack confidence in the accuracy of the data their suppliers provide, creating real operational vulnerabilities. 

• Valuation and cost of capital pressure: Investors demand credible, auditable Scope 3 data and progress against public targets. Companies failing face higher scrutiny, elevating risk profiles and borrowing costs. Studies show firms disclosing Scope 3 enjoy lower borrowing costs, with disclosure premiums averaging ~20 basis points — translating to millions in savings for large enterprises. 

• Competitive disadvantage in low-carbon product markets: Customers increasingly favour low-carbon alternatives. Laggards lose share in growing markets for green steel, recycled materials, or electrified logistics. For instance, Automotive Original Equipment Manufacturers (OEMs) prioritizing low-carbon suppliers gain preferred contracts and pricing power, while high-carbon incumbents face exclusion. Investors are increasingly looking at a company’s customer base – if customers are committed to SBTi and you are not, what is your revenue at risk. 

Scope 3 is a commercial imperative. Anecdotal claims won't cut it — capital allocation demands IRR, NPV, and payback hurdles. Successful leaders build rigorous business cases that tie Scope 3 reductions to financial outcomes, securing buy-in across the C-suite while delivering on those public milestones. 

From stalling strategy to meaningful action 

Progress has stalled for many due to data gaps, supplier resistance, and competing priorities —leaving strategies (and public targets) in PowerPoint rather than operations. However, the 2025 ERM–GlobeScan Sustainability Leaders survey shows that the agenda is evolving toward implementation, with leaders prioritizing renewable energy deployment, low-carbon technologies, and multi-stakeholder collaboration to drive tangible progress against their commitments.  

Below are 7 steps leaders can take to translate this ambition into real progress

1. Talk the executive language – value, risk, and resilience 

Leaders quantify sustainability in CFO-grade metrics: 

• Carbon → avoided costs and opex reductions
• Energy → lower operating expenses and reduced cost of capital
• Low-carbon products → increased revenue and market share → VALUE
• Supplier decarbonization → supply continuity, margin protection, and avoided disruptions → RESILIENCE
• Regulatory exposure and investor scrutiny → mitigated risk profiles → RISK REDUCTION 

Example: A manufacturing client reduced Scope 3 emissions by optimizing logistics and supplier energy efficiency, delivering €15M annual opex savings while de-risking CBAM exposure and advancing toward 2030 milestones. 

2. Take a programmatic view to fund the journey 

Leading companies treat Scope 3 as an investment portfolio across three buckets (illustrated via MACC curves showing abatement potential vs. cost): 

• Bucket 1 — Value creating (negative cost): Energy efficiency, logistics optimisation, material yield improvements, circularity/waste reduction—immediate cash savings. 

• Bucket 2 — Cost neutral: Renewable switching, on-site solar plus battery for energy security, supplier optimisation, process electrification at TCO parity. 

• Bucket 3 — Cost add (hard-to-abate): Low-carbon fuels, green materials, process redesign. There are opportunities for collective action to reduce the ROI such as in Clean Heat programs and group buying of solvents. 

The key: Use savings from Buckets 1 and 2 (paybacks <3-4 years) to fund Bucket 3, layering third-party financing, supplier funds, grants, and carbon credits. Many levers are cost-negative on TCO. 

Example: A chemicals firm used efficiency gains to self-fund green hydrogen pilots, achieving net-positive ROI while cutting Scope 3 by 25% and building momentum for longer-term targets. 

3. Move data from estimates to actuals 

Start with spend-based models; leaders should shift to primary data from activities and suppliers, as well as product-level footprints, to identify targeted levers and strengthen their cases. Digital platforms scale across thousands of suppliers. 

A key insight that challenges conventional thinking: Most companies start with spend-based methods using industry-average emission factors, which often overestimate actual emissions — sometimes by 30-40% or more. Shifting to more accurate activity-based data from suppliers (e.g., actual energy use, material volumes, or transport distances) typically reveals significantly lower emissions than these conservative defaults and allow more targeted and prioritised actions to decarbonize. 

This refinement not only provides a truer picture but also directly lowers reported Scope 3 inventories, reducing exposure to carbon taxes and, where applicable, CBAM-related liabilities (as CBAM defaults are punitive and higher than primary data). More accurate Scope 3 inventories can also be achieved through developing precise Product Carbon Footprints (PCFs) or Life Cycle Assessments (LCAs) of the company's product portfolio, moving from broad estimates to granular, product-specific footprints that uncover hidden efficiencies and further de-risk financial impacts—while demonstrating credible progress toward those 2030, 2040, and 2050 milestones. 

Example: A consumer goods company implemented a platform for primary supplier data, unlocking precise abatement opportunities, revealing overstated emissions due to defaults, and delivering €8M in targeted savings and reduced regulatory liabilities — directly supporting public 2030 reduction commitments. 

4. Engage suppliers at scale 

About 20% of suppliers drive ~80% of emissions. Move beyond requests to: Teach (upskilling/academies), Fund (financing), Collaborate (working groups), Discipline (contracts/incentives), Appreciate (preferred status), Sustain (benefits tracking). Use digital platforms for efficiency. Suppliers must see value, not burden to drive progress. 

Example: An automotive leader provided financing and technical support for supplier renewable procurement, reducing Scope 3 emissions 30% while improving supplier margins through energy savings and aligning with value-chain net-zero goals. 

5. Recognise that Scope 3 is largely suppliers’ Scope 1 and 2 

Scale proven levers: Energy efficiency retrofits, renewable procurement, circularity, low-carbon heat, fleet electrification, material substitution. Provide education, financing, and support. 

Example: A steel buyer rolled out low-carbon steel sourcing with supplier incentives, cutting upstream emissions while securing supply stability amid CBAM and progressing toward 2050 net-zero. 

6. Drive system-level change through collaboration 

Form alliances such as Energize (Renewable Energy Procurement - pharma), industrial clean heat programs (AstraZeneca/Secaro/ERM), or shared platforms. The 2025 ERM–GlobeScan survey highlights multi-stakeholder collaboration as a leading driver of progress. 

Example: The Supply Chain Clean Heat Program unites peers to test shared infrastructure, accelerating adoption beyond individual capabilities and supporting sector-wide milestones. 

7. Align finance, procurement, and sustainability 

High-performers align targets/incentives, embed in capital allocation and procurement, and establish cross-functional governance. Engage early for credible cases. 

Example: A retailer integrated Scope 3 into category strategies, tying procurement bonuses to low-carbon sourcing—driving 15% emissions reduction with cost neutrality and credible progress against public targets. 

Conclusion 

Scope 3 is not primarily about reporting emissions or hitting distant public milestones for show. It is about: 

• Protecting margin from transition risk
• Unlocking efficiency and innovation value
• Building structurally more resilient supply chains
• Strengthening long-term enterprise value 

Or put simply: Companies that master Scope 3 will not just report lower emissions or meet their stated 2030/2040/2050 targets, they will build lower-cost, more resilient, and more competitive businesses. The question isn't whether to act, it's whether you'll lead the transformation or be disrupted by it. Forward-thinking leaders are already proving the business case; the window for advantage is open but closing fast.
