Manufacturers are turning digital tools to tackle Scope 3 emissions and achieve net zero

For manufacturers focused on achieving Net Zero emissions, the most significant challenge lies not within the factory walls alone but extends deeply into the supply chain. According to Daniel Usifoh, Co-founder of Axiom Sustainability Software, understanding and addressing Scope 3 emissions is critical. These emissions, which encompass the environmental impact of purchased goods, transportation, product use, and end-of-life disposal, frequently account for more than 80% of the total carbon footprint for industrial businesses. This reality underscores that decarbonisation efforts must begin long before raw materials reach the plant and continue far beyond when products leave it.

This focus on Scope 3 emissions has become increasingly urgent due to mounting regulatory requirements and market pressures. Frameworks such as the EU Corporate Sustainability Reporting Directive (CSRD) and the UK’s Net Zero Strategy, along with initiatives like the Science Based Targets initiative (SBTi), are pushing manufacturers towards full value-chain transparency. Investors and procurement teams now commonly demand detailed carbon data from suppliers before contracts are awarded, making Scope 3 emissions management a strategic priority rather than just a compliance issue. The transparency and measurable reductions in emissions directly influence market access, supply chain resilience, and long-term competitiveness.

Recent research highlights the magnitude of the challenge. A report by CDP and Boston Consulting Group found that in 2023, corporates reported Scope 3 supply chain emissions averaging 26 times higher than their direct operational emissions (Scopes 1 and 2). Furthermore, upstream emissions from sectors such as manufacturing, retail, and materials had a combined footprint exceeding the total CO₂ emissions of the entire European Union in 2022. Despite this significant impact, only 15% of corporates had set targets specifically addressing Scope 3 emissions, revealing a substantial gap in supply chain emissions management.

Similarly, a study from the MIT Center for Transportation & Logistics and the Council of Supply Chain Management Professionals found that Scope 3 emissions make up about 75% of a company’s overall emissions on average. However, tracking these emissions remains highly complex due to the intricate web of suppliers and customers involved, complicating efforts to effectively measure and mitigate environmental impacts throughout the supply chain.

Technological innovations are emerging as essential tools to address these complexities. Digital sustainability platforms, carbon accounting software, AI and machine learning, blockchain for traceability, and automation offer significant opportunities to enhance emissions data accuracy and operational efficiency. For manufacturers operating within narrow margins, these technologies can concurrently reduce costs and carbon footprints, a crucial advantage in today’s competitive landscape.

Practical steps for manufacturers include engaging suppliers to foster open communication on emissions data, even if initially imperfect; prioritising emissions hotspots by identifying the minority of suppliers or processes responsible for the bulk of emissions; and integrating sustainability tracking with existing ERP, MES, or procurement systems to streamline data collection. The adoption of standardised reporting frameworks, such as the GHG Protocol or SBTi guidance, and piloting innovative digital tools in controlled environments can further support decarbonisation efforts.

Ultimately, manufacturers that can demonstrate transparency and show measurable reductions in Scope 3 emissions are already beginning to gain preferential contracts and strengthen customer relationships. The supply chain has become a critical battleground for Net Zero credibility, with the most successful companies combining operational excellence with digital innovation to cut carbon emissions across the entire value chain. While managing Scope 3 emissions presents a complex and evolving challenge, it also represents a significant opportunity. With the right tools and strategies, manufacturers can transform what was once a regulatory burden into a powerful operational advantage.
