British Charcoal Brand Linked to High-Deforestation Supplier in Paraguay

Big K, a prominent British charcoal manufacturer, is facing allegations that its supply chain is linked to one of the world's highest rates of deforestation. According to a recent investigation by Global Witness, the brand sources materials from Taruma, a company operating in Paraguay's Gran Chaco forest. The report suggests that Taruma purchases large volumes of wood from cattle farms that have cleared extensive areas of primary forest, raising concerns about the environmental impact of these supply chains.

The investigation highlights that Taruma buys wood from deforested land, including a massive estate owned by BrasilAgro, a subsidiary of the agro-giant Cresud. This specific farm, which spans over 60 square kilometers, has cleared more than 28,000 hectares of forest, an area larger than the city of Birmingham. Broader data indicates that Cresud has been responsible for over 170,000 hectares of deforestation across South America in the last two decades, illustrating the scale of land conversion associated with these agricultural operations.

Corporate Responses and Legal Context

In response to the allegations, Taruma stated that it complies with Paraguayan law in its sourcing practices. The company maintains that it does not play a role in the decisions made by landowners to convert forested land for other uses. Meanwhile, Big K emphasized its commitment to sustainability on its website, asserting that its due diligence procedures prevent it from engaging with suppliers who source illegal charcoal. The brand claims that the wood it uses comes from government-controlled land that has already been cleared for cattle rearing.

Despite these assurances, the legal framework in the United Kingdom remains a point of contention. The UK law designed to ensure that supply chains are free of deforestation has not been fully enforced five years after it was passed by Parliament. This gap between legislation and enforcement creates a complex environment for consumers and regulators alike, as the actual impact of imported goods on global forests remains difficult to verify without robust oversight mechanisms in place.

Sustainability Claims and Supply Chain Transparency

Big K’s public messaging presents a clear narrative of responsibility, stating that responsible sourcing is achieved by only using trees that are due to be cut down. The company argues that its procedures ensure it does not engage with suppliers involved in illegal sourcing. However, critics point out that the distinction between legal and illegal sourcing can be blurred in regions with weak land-use governance, where deforestation is often facilitated by legal loopholes or insufficient monitoring of land rights.

The tension between corporate sustainability claims and the reality of deforestation in the Gran Chaco underscores the challenges of verifying supply chain integrity. While companies like Big K and Taruma cite compliance with local laws and due diligence, the sheer volume of cleared land attributed to their suppliers suggests that standard compliance checks may not be sufficient to prevent environmental harm. This situation highlights the need for more rigorous, independent verification of sourcing practices in the global charcoal market.

Regulatory Gaps and Future Enforcement

The delay in enforcing the UK’s zero-deforestation law has allowed such supply chain issues to persist. According to the Business and Human Rights Centre, this regulatory vacuum leaves consumers and environmental advocates without a clear legal mechanism to hold companies accountable for indirect contributions to deforestation. As the law remains unenforced, the burden of proof often falls on NGOs and investigative journalists to uncover and publicize these links, rather than on regulators to proactively police the market.

Looking ahead, the focus will likely shift toward how and when the UK government implements its deforestation legislation. Stakeholders are watching for signs of increased regulatory pressure on major brands to disclose their supply chains more transparently. The case of Big K and Taruma serves as a critical test case for whether legal frameworks can effectively deter deforestation-driven sourcing, or if corporate self-regulation will continue to rely on voluntary claims that may not fully reflect the environmental footprint of their operations.
