Scope 3 strategies: turning complex challenges into collaborative solutions

At the recent Scope 3 Innovation Forum in Washington DC, leaders from across industries gathered to take part in focused roundtable discussions to discuss the pressing challenges in reducing scope 3 emissions. The roundtables explored diverse topics ranging from supplier engagement and procurement metrics to the role of consumers and strategies for a just transition. Here are some of the main discussion points. 

Effective scope 3 data management hinges on building trust, actionable insights and clear mechanisms for validation. Yet its current shortcomings were a central theme of the discussion. Participants underscored the importance of using data not just for compliance but as a tool for supplier engagement and risk mitigation. The discussion called for enhanced methods to verify supplier data and emphasised that data collection must serve as a tool for trust-building and decision-making. Aligning reporting with supplier engagement strategies can strengthen relationships and reveal risk mitigation opportunities.

Engaging suppliers who are less responsive or face greater challenges in aligning with scope 3 goals requires a nuanced approach. Participants stressed the importance of speaking the suppliers’ language and aligning with their goals to foster collaboration. Finding internal allies within supplier organisations and addressing the perennial “who pays” question emerged as crucial strategies for overcoming barriers and ensuring mutual benefits.

Embedding clear, measurable sustainability metrics in procurement processes is essential for driving meaningful change. Discussions highlighted the importance of aligning metrics with supplier maturity, science-based targets and product-level footprints. Companies can use incentives such as co-investments, longer contracts and premium payments to encourage supplier alignment. Integrating sustainability and procurement teams was identified as a structural shift that can enhance collaboration and impact.

While science-based targets (SBTs) provide a framework for climate action, participants identified challenges in creating a compelling business case and addressing systemic barriers. Sector-specific guidance, reducing data collection costs through industry collaboration and refining standards to incentivise the right behaviours were highlighted as key focus areas for advancing SBTs.

A short-sighted focus on carbon reduction risks sidelining marginalised suppliers, including smallholder farmers and SMEs. Participants emphasised integrating just transition principles to ensure vulnerable stakeholders are supported through upskilling and capacity-building initiatives. Examples of just transition principles and initiatives such as diversity accelerators showcased how inclusive approaches can deliver dual benefits — supporting climate goals while building resilient supply chains.

Discussions around carbon insetting raised critical questions about definitions, ownership of data and avoiding double counting. Participants debated whether scope 3 registries would aid or hinder progress and stressed the importance of directing investments to farmers rather than intermediaries. Clear frameworks for validation and transparency are needed to bolster trust and effectiveness in insetting projects.

The challenge of allocating accountability and costs for carbon reductions sparked some dynamic conversations. Co-investment models, internal carbon pricing mechanisms, and department-level carbon taxes were proposed as potential solutions. Standardising methods for connecting investments to outcomes was identified as a key enabler for progress.

Consumers play a partial but important role in reducing scope 3 emissions. However, their impact is limited by confusion stemming from inconsistent certifications and standards. Participants called for greater alignment among companies, policymakers, and other stakeholders to provide clearer guidance and reduce the burden on consumers.

The roundtable discussions highlighted that achieving scope 3 emission reductions requires collaboration across the supply chain, innovative incentive structures and a commitment to inclusivity. Standardising data, empowering suppliers and integrating sustainability into procurement processes are critical steps forward. With collective action and a shared vision, companies can turn scope 3 challenges into opportunities for meaningful and sustainable impact.
