From intention to impact: Actualising Scope 3 emissions action

In Part One of Tackling Scope 3 emissions, we explored how organisations can take real first steps toward decarbonisation - steps that also open new opportunities for growth and profitability. But what’s driving this shift? And why does Scope 3 matter now more than ever?

Scope 3 emissions, often referred to as value chain emissions, are the indirect emissions that occur across a company’s upstream and downstream activities. These are categorised into 15 distinct groups, including emissions from purchased goods and services, capital goods, transportation and distribution, business travel, the use of sold products and their end-of-life treatment.

For most companies, Scope 3 emissions are the dominant contributor to a company’s carbon footprint, averaging 11.4 times greater than direct (Scope 1) and energy-related (Scope 2) emissions. This makes them not only critical to achieving science-aligned net zero targets, but also a litmus test for corporate climate credibility.

It is also being seen as a strategic means to achieving long-term business value. The GHD Sustainability Monitor underscores this: 97 percent of surveyed executives believe their sustainability agenda is already delivering commercial value to their organisation.

Tackling Scope 3 emissions creates significant opportunities which can enhance operational efficiency, drive product and service innovation and deepen supplier and customer relationships. When this happens, it strengthens business resilience and contributes directly to the bottom line.

This shift reflects a broader change in mindset: from shareholder supremacy to stakeholder-driven value creation. Environmental responsibility is no longer a parallel agenda; it is now a defining component of corporate strategy.

At the same time, expectations from customers, investors and procurement leaders are intensifying. Transparent Scope 3 reporting is no longer just a compliance activity - it’s a signal of intent and capability. The insights gained through Scope 3 analysis are increasingly driving decisions around supplier selection, investment risk and even talent attraction, making it a differentiator in competitive markets.

For instance, Unilever now requires suppliers to disclose carbon footprints, and BlackRock integrates ESG metrics into its firmwide investment risk framework, signalling a growing demand for low-carbon supply chains.

Despite the clear strategic and environmental benefits, managing Scope 3 emissions remains a highly complex undertaking. The GHD Sustainability Monitor found that Scope 3 reporting was identified by many organisations as particularly difficult to address, especially in terms of capturing data that is timely, robust, and accurate.

Several key hurdles contribute to this complexity:

• Data transparency and accuracy: A major obstacle is the difficulty in sourcing consistent, reliable emissions data from a wide array of suppliers and value chain partners - many of whom may lack the capacity, tools or knowledge to provide accurate carbon accounting.
• Supply chain complexity: Global, multi-tiered supply chains make it difficult to trace emissions across the value chain, particularly when supplier data is inconsistent or limited. While emerging standards like the Science Based Targets Initiative (SBTi) 2.0 are shifting toward Tier 1 supplier reporting to ease this burden, significant challenges remain in building visibility and consistency across diverse supplier networks.
• Lack of standardisation: While frameworks such as the GHG Protocol’s Scope 3 Standard provide useful guidance [3], methodologies for data collection, calculation, and reporting remain inconsistent. This variation hinders comparability and undermines effective benchmarking.
• Engagement and collaboration: Successfully managing Scope 3 emissions depends on building strong, cooperative relationships across the value chain. That requires time, trust and a shared commitment to transparency.
• Resource constraints: Many organisations, particularly mid-sized firms, face limitations in both budget and internal expertise. These constraints make it difficult to dedicate sufficient resources to Scope 3 reporting initiatives in a sustained and systematic way.

These challenges are not uniform across industries. The GHD Sustainability Monitor highlights that sectors such as mining report significant difficulties, including a lack of customer demand for sustainable alternatives and limited options for low-carbon operations. In contrast, the property sector tends to be more advanced, benefiting from decades of experience with measurable construction codes and tools that help visualise environmental impact.

Understanding these sector-specific dynamics is essential for designing realistic, tailored Scope 3 data collection strategies that acknowledge each industry's unique operating environment and challenges.

The narrative around Scope 3 emissions and reporting is changing rapidly. What was once seen as too complex, or peripheral, is now emerging as central to strategic value creation.

Key areas where this value is realised include:

• Efficiency and cost reduction: Mapping Scope 3 emissions often highlights inefficiencies in energy, materials and waste throughout the value chain. Targeted interventions can produce substantial cost savings for both the organisation and its suppliers.
• Supply chain resilience: Engaging suppliers and customers on emissions reduction creates stronger, more transparent relationships and builds resilience against a growing array of disruptions, from climate shocks and geopolitical risks to shifting trade policies. A resilient supply chain is now crucial for operational stability and business continuity.
• Enhanced brand reputation and customer loyalty: Consumers and business clients are increasingly favouring brands that act decisively on environmental action. Visible progress on Scope 3 emission reduction enhances reputation, builds trust and helps secure customer loyalty in an environmentally conscious market.
• Investor appeal and access to capital: Environmentally aligned investors are looking for companies that demonstrate credible, forward-looking climate action. A robust Scope 3 emissions and reporting strategy signals effective risk management and long-term thinking, helping to attract investment and potentially lower financing costs.
• Talent attraction and retention: A company’s environmental performance is increasingly influencing employment decisions, particularly among younger workers. Demonstrating authentic action on Scope 3 emissions enhances employer branding and helps attract purpose-driven talent.
• Upskilling and retooling the supply chain: There is a clear opportunity to build supplier capabilities. Investing in collaborative training and support not only improves sustainability outcomes across the value chain but also fosters shared innovation and mutual growth.

A key enabler in achieving these outcomes is the strategic use of data, as mentioned above. The ability to capture, analyse, and act on supply chain emissions data is becoming a differentiator in its own right. It can open new pathways for partner engagement, impact measurement and adaptive decision-making.

Organisations that lead on Scope 3 emissions and reporting are also best positioned to shape emerging standards, influence supplier behaviour, and pioneer new business models. Whether through co-investment in supplier decarbonisation, embedding climate criteria in procurement, or establishing collaborative emissions baselines, these leaders are creating ecosystems of shared value and competitive advantage.

For executives looking to improve business performance and build a more resilient, future-ready operation, the following recommendations offer a strategic foundation.

1. Embed Scope 3 into core business strategy
Integrate Scope 3 considerations into broader strategic planning, risk management and innovation efforts. It must move beyond the sustainability team and become a business-wide imperative.

2. Champion a collaborative approach
Build trust-based relationships with suppliers, viewing them not as emission sources to be audited but as strategic partners in shared decarbonisation goals. Collaboration, not compliance, is the key to scalable impact.

3. Invest in meaningful data capabilities and start with strategy
Before investing in platforms, define what data matters. Focus on capturing information that enables meaningful decisions, prioritising strategic insight over sheer volume.

4. Start pragmatically, scale based on value
Avoid being paralysed by complexity. Begin with manageable steps in high-impact areas, then build momentum through continuous learning, adaptation and expansion.

5. Reimagine your supply chain
Let Scope 3 be a catalyst for transformation. Beyond reporting, it offers a unique opportunity to redesign your supply chain for greater resilience, efficiency, and long-term advantage.

Decarbonising value chains is a long-term undertaking - it’s a marathon not a sprint. While short-term economic uncertainty may lead some to hesitate, the fundamental drivers - regulatory pressure, investor expectations, potential financial upside, customer demands and the quest for operational resilience - remain firmly in place.
