In an age where consumers are increasingly concerned about the origins of the products they purchase, the need for robust legislation to uphold human rights and environmental standards within supply chains has never been more pressing. Recent reports have highlighted the troubling realities faced by workers in garment factories across South Asia and the exploitation linked to global supply chains. As such, calls for a Business, Human Rights and Environment Act are gaining momentum, urging the government to take decisive action to protect both people and the planet.

Uncovering the Dark Side of Global Supply Chains

A recent investigation by Amnesty International has shed light on egregious labour rights violations affecting garment workers in Bangladesh, India, Pakistan, and Sri Lanka. These findings are part of a broader pattern of human rights abuses that taint the supply chains of numerous well-known fashion brands. Additionally, a BBC report revealed that tomato paste sold in the UK was sourced from tomatoes harvested under forced labour conditions in China. Such revelations underscore the urgent need for transparency and accountability in how goods are produced and traded.

The World Benchmarking Alliance’s 2026 assessment paints a stark picture: only 10 per cent of the world’s leading companies actively assess human rights risks within their supply chains. Alarmingly, merely one in five companies takes the initiative to trace their products and evaluate their ecological impact. While consumers enjoy affordable goods, they remain largely unaware of the exploitation and environmental degradation that occur far from their sight.

The Legislative Response: A Call to Action

Given the complexity of global supply chains, it is impractical for individuals to scrutinise every product they consume. This is where policymakers must step in. It is the responsibility of legislators to ensure that companies conduct thorough due diligence in alignment with the environmental and human rights standards citizens expect. The current Labour government, which has made strides in promoting workers’ rights, must extend its mandate beyond domestic borders to encompass international supply chains.

Advocates are now pushing for the introduction of a comprehensive Business, Human Rights and Environment Act that would mandate companies to evaluate and mitigate human rights and environmental risks in their operations. Such legislation could be transformative, holding multinational corporations accountable for their practices and discouraging UK banks from funding activities that contribute to deforestation and land seizures, particularly in sensitive regions like the Amazon rainforest.

The Business Case for Ethical Practices

The ethical implications of this proposed legislation extend beyond moral responsibility; they also present a compelling business case. Many of the UK’s largest firms are already complying with the European Union’s Corporate Sustainability Due Diligence Directive, which necessitates responsible sourcing to access the European market. If the UK fails to implement similar standards, it risks becoming a haven for unethically sourced products while undermining British businesses committed to sustainable practices.

Notably, over 50 global companies, including notable UK brands such as Tesco, Twinings, and John Lewis, have publicly endorsed calls for human rights due diligence legislation. This growing coalition highlights an emerging trend: consumers increasingly prefer to support businesses that prioritise ethical sourcing and sustainability. By adopting mandatory due diligence laws, the government can facilitate ethical consumption, enhance risk management for businesses, and ultimately contribute to the growth of responsible British enterprises.

Bridging the Gap Between Consumers and Supply Chains

Current legislation, such as Section 54 of the Modern Slavery Act 2015, falls short by only requiring companies to report on their operations without mandating them to actively address and rectify any issues. Furthermore, existing laws do not sufficiently tackle the environmental crises that are often intertwined with human rights abuses. For example, illegal mining practices not only threaten the environment but also jeopardise the well-being of communities affected by pollution and exploitation.

Human rights and environmental issues are inextricably linked, and any effective due diligence legislation must address both aspects. The EU’s regulations encompass this dual focus, and failing to do so could leave the UK vulnerable to becoming a dumping ground for environmentally harmful products. Consumers should not have to navigate these ethical complexities alone; they deserve assurance that the goods they purchase meet high human rights and environmental standards.

Why it Matters

The proposed Business, Human Rights and Environment Act represents a pivotal opportunity to reform how companies operate within global supply chains. It would provide a framework for accountability that aligns with the values of today’s conscious consumers, ensuring that the products we rely on are not only safe but ethically produced. The implementation of such legislation would not only protect vulnerable communities and the environment but also strengthen the integrity of British businesses on the global stage. As we face complex global challenges, it is imperative that we advocate for laws that foster a sustainable and just world for all.
