Tackling Scope 3 emissions is the new frontier for corporate climate action, yet bridging the gap between corporate targets and supplier reality remains a complex challenge.

For many global organisations, the race to net zero has moved beyond their own four walls. While companies have made significant strides in addressing Scope 1 and 2 emissions, the real challenge, and the greatest opportunity, lies in Scope 3: the supply chain.

As corporations set ambitious climate goals aligned with RE100 and the Science Based Targets initiative (SBTi), they frequently encounter a bottleneck. How do you ensure thousands of distinct suppliers, often located in complex regulatory environments across the Asia Pacific (APAC), transition to renewable energy?

The hurdle: Why supply chain action is difficult

The path to a green supply chain is rarely straightforward. Suppliers often face practical barriers that prevent them from switching to renewables independently. These include a lack of technical knowledge, limited procurement volume (making them unattractive to large energy developers), and the sheer complexity of local energy markets.

In the APAC region specifically, the challenges are magnified by:

  • Regulatory uncertainty: Rapidly evolving policies and delays in electricity infrastructure development.
  • Geographical constraints: Uneven distribution of renewable resources. For example, in China, the resource-rich Northwest offers lower premiums, but most manufacturing hubs are located in coastal regions with grid constraints.
  • Market volatility: Disparities in renewable energy prices across provinces and municipalities make financial planning difficult.

Consequently, companies face a "geographic mismatch" where their suppliers are located in regions with high premiums, limited transmission capabilities, or fragmented regulatory landscapes.

What this means for your business

Failing to address these barriers does not just endanger your climate targets; it means missing out on significant commercial advantages.

Despite the complexities, the economic case for renewable energy in APAC is strengthening. Our market analysis and practical implementations highlight substantial savings potential:

  • India and Vietnam: Renewable sourcing can deliver 25–40% lower costs compared to traditional grid sourcing.
  • China: Strategic provincial selection can unlock cost advantages by avoiding premiums associated with unbundled Renewable Energy Certificates (RECs).

The implication is clear: companies that proactively manage their supply chain’s energy transition can secure long-term price stability and gain a competitive edge, while those who wait may face rising costs and compliance risks.

Strategic solutions for supply chain decarbonisation

Strategy 1: Set clear targets (Mandating)

The foundation of success is setting clear, enforceable renewable energy targets for suppliers. These should be aligned with international standards like RE100 and SBTi. However, a mandate is only as good as its enforcement; it must be supported by robust tracking and compliance mechanisms to ensure suppliers are actually making the switch. To ensure action is prioritized, SBTi’s latest draft for its updated Net Zero guidance provides energy-specific targets for high energy consumption activities.

Strategy 2: Build capacity (Education)

You cannot expect suppliers to navigate complex energy markets alone. Effective programmes involve conducting targeted, local-language workshops and personalised follow-ups. This "Knowledge Building" phase is critical to bridging the gap between a supplier's willingness to change and their ability to execute.

Strategy 3: Leverage scale (Aggregation)

This is the most transformative solution. By aggregating demand across multiple suppliers, companies can overcome the issue of limited volume, unlocking "economies of scale" that individual factories could never achieve alone.

Success Stories in APAC:

In Vietnam

In Vietnam

We are seeing success with Direct Power Purchase Agreements (DPPAs). By identifying and bundling key suppliers, companies can improve negotiation leverage to secure competitive pricing. We are also actively advising clients in Vietnam to engage partners across their supply chains to jointly pursue DPPA opportunities.

In China

In China

We help clients navigate the Green Power Trading (GPT) landscape to avoid the premiums of unbundled RECs. For Nike, South Pole managed diverse supplier "Buyer Groups," handling the Request for Proposal (RFP) process to secure a long-term framework agreement across multiple provinces. Similarly, we facilitated a 5-year agreement for Philips to source 48,000 MWh/year from a solar-PV system in Jiangsu, transitioning their Suzhou facility to 100% renewable electricity.

In Malaysia & Thailand

In Malaysia & Thailand

We are actively advising clients on recently developed physical PPA frameworks to capitalise on emerging market opportunities.

Looking ahead: The future of sourcing in APAC

The landscape of renewable sourcing in the Asia Pacific is maturing rapidly. We foresee robust growth in aggregated PPAs as the primary vehicle for tackling Scope 3 emissions.

While markets like China will see narrowing regional price disparities and regulatory evolution, emerging markets like Vietnam and India will see accelerated adoption of corporate PPAs due to the financial stability they offer against volatile energy costs.

Success will no longer be about simple procurement; it will depend on strategic supplier aggregation, deep regulatory alignment, and rigorous project selection. By acting now to embed these strategies into your procurement policy, your organisation can mitigate risk and lead the transition to a sustainable future.
