Decarbonising your value chain: Tackling Scope 3 emissions for profitability and business growth

The global push to decarbonise has moved from the margins to the mainstream, becoming a core strategic and financial priority for strategy-driven organisations.While much attention has been directed toward reducing direct emissions (Scope 1 and 2), the companies that are maximising the value of decarbonisation are also focused on Scope 3: the indirect emissions generated across a company’s value chain.

Often accounting for more than 70 percent of an organisation’s total carbon footprint, these emissions - primarily arising from purchased goods, transportation, waste and the use of sold products - are more than just an environmental liability. They’re a strategic lever for improving efficiency, strengthening supply chains and building trust with investors and customers.

Despite their significance, most organisations are still in the early stages of addressing Scope 3 emissions and reporting. The GHD Sustainability Monitor found that “decarbonising operations” is the top area of concern for 550 global executives, with Scope 3 emissions singled out as the “great unknown” due to persistent data collection and accuracy challenges. 

But there’s momentum building. Executives across sectors are starting to treat Scope 3 reporting not as an afterthought, but as a boardroom priority - one that offers real commercial upside. A clear Scope 3 strategy can improve profitability, enhance resilience and enable smarter decision-making around procurement, investment and risk. 

Here’s five practical ways to help organisations move forward - starting with the data that matters, engaging suppliers with purpose and embedding emissions thinking across the value chain. 

Transitioning from recognition to results in Scope 3 decarbonisation requires more than ambition. It demands a clear, strategic roadmap. This is not about finding the perfect, all-encompassing solution from day one. It’s about starting with intent, learning through action and building momentum over time.

Rather than attempting to address all 15 Scope 3 categories at once, organisations should begin by identifying their highest-impact emission sources or “hotspots”, along with the most influential suppliers.

The challenge with data often lies not in the tools used to collect it, but in the thinking that precedes the process. Many companies default to generic surveys without clearly defining what data is meaningful and why. A targeted approach that combines data collection with decision-making priorities is far more effective and resource efficient. 

• Focus efforts on high-emission categories and strategic suppliers. 
• Define the purpose and application of each data point before collection. 
• Align resource allocation with the potential for greatest impact. 

Rather than treating suppliers as compliance risks to be monitored, leading organisations treat them as partners in the transition. 

Key strategies include:

• Open conversations: Initiate transparent conversations around shared decarbonisation goals, timelines and barriers. 
• Capacity building: Provide training, resources and technical support to help suppliers measure and reduce emissions.  
• Incentivisation: Develop procurement frameworks that reward strong sustainability performance. 
• Shared learning platforms: Establish forums for suppliers to collaborate. Since many suppliers serve multiple companies, these platforms also foster cross-industry collaboration. 
• Alignment: Design and implement a proactive stakeholder connection plan that synchronises targets, messaging and expectations across the supplier base. 

Data is foundational, but it must be actionable. Purposeful data collection enables strategic decisions, not just regulatory compliance. The aim should be a system that that moves from estimation to precision.

• Use proxies and industry averages initially: When primary data is unavailable, start with credible proxy figures to identify major emissions sources and prioritise improvement areas. 
• Adopt a tiered approach: Begin with key strategic or high-emission suppliers and expand data collection efforts over time. 
• Leverage technology: Utilise digital tools, platforms and AI to streamline data collection, support analysis and enhance transparency. Data-driven supplier engagement is where disruption and value creation increasingly converge.

External collaboration must be matched by internal commitment. 

• Cross-functional teams: Create dedicated internal working groups spanning procurement, product development, sustainability, finance and operations to embed Scope 3 thinking across business functions. 
• Education and awareness: Develop internal campaigns and training to raise awareness of Scope 3 emissions and empower teams to contribute to emissions reduction goals. 
• Integration into procurement: Embed emissions criteria into supplier onboarding, codes of conduct and purchasing decisions. 

Strong governance turns strategy into action. Clear targets, defined responsibilities and transparent reporting are essential for credibility and momentum. 

• Set clear, time-bound targets: Establish specific Scope 3 reduction goals aligned with broader decarbonisation strategy. Assign accountability to senior leadership to ensure ownership. 
• Report transparently and regularly: Communicate progress, challenges and methodologies in line with emerging global frameworks. Transparency builds trust with stakeholders, including customers, investors and regulators.

Organisations that act decisively now will be better positioned to capitalise on the opportunities ahead. They will build supply chains that are more robust, adaptive and commercially competitive in an economy shaped by climate resilience and stakeholder accountability.
