Sustainability is no longer something businesses can ignore. It’s no longer just a buzzword or something to feature on a website. The pressure to make supply chains more sustainable is growing, and the shift has moved beyond ethical preferences to real financial consequences.
If you’re running a business that relies on suppliers from around the world, it’s time to rethink how you manage and source your products. Whether you’re navigating complex regulations or seeking new ways to reduce environmental impacts, now is the time to rethink how your supply chain operates, both domestically and abroad.

Why sustainability pressures are transforming global supply chains
Sustainability has moved far beyond the realm of public relations and marketing. For UK businesses, it will soon be a legal and financial obligation. The UK government’s recent release of new Sustainability Reporting Standards (UK SRS) in February 2026 marks a significant step in this transformation. The rules mean that listed companies will have to treat their climate data with the same rigour as their financial data.
But the shift doesn’t stop there. Companies may have to start taking responsibility for their entire value chain. The move from the old Task Force on Climate-related Financial Disclosures (TCFD) framework to the more stringent International Sustainability Standards Board (ISSB) framework (IFRS S1 and S2) underscores this.
Under the new guidelines, companies will have to be transparent with Scope 3 emissions – the indirect carbon footprint generated by suppliers and their activities. This means your company may become responsible for monitoring, measuring and reducing the carbon emissions of every supplier in your network, right down to the most distant ones.
Alongside stricter reporting requirements, UK businesses now face new risks when it comes to environmental claims. The Competition and Markets Authority (CMA) has revised its guidance on ‘greenwashing’, and UK businesses could face fines up to 10% of their global turnover if they’re found to be making misleading environmental claims anywhere in their supply chain. This is a wake-up call for businesses that may have been treating sustainability as an afterthought. Now, it must be thoroughly integrated into every business process.
The rise of cross-border environmental compliance
As businesses in the UK become more aware of their environmental responsibilities, they must also navigate the complexities of international regulations. One of the key changes businesses need to prepare for is the EU’s Carbon Border Adjustment Mechanism (CBAM). Starting in January 2026, this regulation switched from a reporting phase to a ‘definitive’ phase. Essentially, UK exporters are now facing financial charges based on the carbon intensity of their products.
In the coming years, the UK will roll out its own CBAM regulations, with the UK’s CBAM due to come into force in January 2027. The UK government’s secondary legislation mirrors the EU’s rules, and industries such as steel, fertilisers, and aluminium are set to be heavily impacted. Businesses will need to prove that their supply chains are meeting carbon standards or face additional charges when exporting to the EU.
In addition to carbon border taxes, the UK’s Extended Producer Responsibility (EPR) scheme, which will reach full implementation in 2026, adds another layer of complexity for UK firms sourcing packaging materials from global suppliers. This could impact UK companies that rely on global suppliers, particularly in regions where recycling standards are less stringent. It’s crucial to start preparing for these changes now, as they will undoubtedly affect sourcing decisions.
The legal complexity of managing sustainable suppliers internationally
Sustainability is ultimately a legal challenge for businesses, too. The legal landscape governing international supply chains is becoming increasingly complex. In the EU, the Corporate Sustainability Due Diligence Directive (CSDDD) has already set high standards for businesses. While the CSDDD was revised in 2025/26 to narrow its scope, it still applies to large UK companies with significant turnover in the EU.
The biggest challenge here is the growing disparity between local laws in different countries. A supplier in China, for example, may comply with local environmental regulations but may fail to meet the requirements of the UK’s Modern Slavery Act or the EU’s Forced Labour Regulation. This creates a gap in your supply chain, and in some cases, could leave you in a legal grey area where goods may not be able to move across borders due to non-compliance.
Businesses also need to ensure that their contracts with suppliers include sustainability-linked clauses. These clauses provide the legal framework needed to terminate a contract if a supplier fails to meet sustainability standards. But these clauses must be carefully drafted, as they can lead to costly legal disputes if they are not enforceable or clearly defined. Legal advice on how to create these clauses is essential to ensure you don’t inadvertently open your business up to legal action.
How international networks support transformation
A key to transforming your supply chain lies in having access to accurate, real-time data from your suppliers. However, in global supply chains, simply collecting data isn’t enough. You need to verify the data, especially when it comes to sustainability claims. Local expertise is crucial to this process.
Having a network of local experts who understand the nuances of sustainability regulations in different countries can make a world of difference. Take, for example, suppliers in Brazil, where strict regulations govern forest-risk commodities, or in Vietnam, where there are complex waste disposal rules for manufacturers. A network with boots on the ground in these countries will help ensure that the data you’re receiving from suppliers is credible, accurate, and compliant with local regulations.
Legal support with global supply chains is becoming essential for businesses trying to navigate the growing web of regulations. Global legal networks can help businesses stay compliant with local rules while also ensuring that they are following best practices across their entire supply chain. A single point of contact for these regulations can help prevent what is often referred to as ‘compliance sprawl’, where a company is left managing dozens of different sets of regulations in multiple countries.
What should UK businesses prioritise?
To stay ahead of the curve, UK businesses need to start taking concrete steps to ensure their supply chains are prepared for the challenges ahead. Here’s a simple checklist to help you stay on track:
- Tier 1-3 mapping: Using frameworks like the Taskforce on Nature-related Financial Disclosures (TNFD), map not only your carbon risks but also biodiversity risks throughout your supply chain. This will help identify potential vulnerabilities and opportunities for improvement.
- Carbon verification: Don’t rely solely on your suppliers’ self-reported carbon data. Require third-party verification to ensure that the data meets the EU’s CBAM standards.
- Sustainability clauses: Update your contracts with suppliers to include clauses that ensure you have the right to audit their sustainability practices. This will give you the legal backing to request transparency and enforce compliance.
- CBAM account readiness: Make sure your EU distributors have registered as Authorised CBAM Declarants. If they haven’t, you risk delays at the border that could affect your ability to trade smoothly with the EU.
As sustainability becomes an ever more pressing issue, UK businesses must act swiftly and strategically to manage their global supply chains. With the right legal support, a clear understanding of evolving regulations and a commitment to transparency, companies can build compliant, environmentally responsible supply chains that meet the needs of today and tomorrow.
