Analysis reveals overseas environmental toll of uk consumption
Posted on Friday 22 May 2026
The stark figure forms the centerpiece of an environmental assessment released by the Stockholm Environment Institute (SEI) at the University of York.
Published to coincide with UK Overshoot Day—the date when the UK would exhaust the planet’s natural resources if the whole world consumed at the same rate—the data reveals that 99.7% of the deforestation associated with UK consumption occurs entirely outside British borders.
The findings, drawn from the latest Global Environmental Impacts of Consumption (GEIC) indicator, serve as a major warning to policymakers. University of York researchers argue that evaluating environmental progress purely at a domestic level fundamentally overlooks the catastrophic ecological damage embedded within international supply chains.
The GEIC data maps the hidden global footprint of UK supply chains, revealing international impacts on water stress, deforestation and its carbon emissions, and wildlife extinction risks.
It reveals that supply chains for household staples like coffee, chocolate, and rice are associated with global species extinctions risk and water stress in producer nations.
This heavy overseas impact extends to greenhouse gas emissions and biodiversity pressures. Out of 9.43 million tonnes of greenhouse gas emissions generated by UK-linked deforestation, 9.36 million tonnes were released abroad.
Furthermore, the researchers have worked with collaborators at the University of Cambridge on integrating their “LIFE score” into the model. This reveals that over 98% of the species extinction risks associated with the habitat conversion required to meet British consumption occur in overseas nations, with daily supermarket staples contributing to a loss of habitats that continues to drive global biodiversity to the brink.
The model also tracks international water use. UK consumption was linked to an estimate of 6.58 billion cubic metres of blue water use (largely associated with agricultural irrigation) globally, of which 6.51 billion cubic metres was associated with production outside the UK. This international water footprint includes extraction from highly water-scarce nations, including India, Pakistan, and Spain, and is associated primarily with UK consumption linked to commodities such as wheat, rice, and cotton.
Professor Chris West, from Stockholm Environment Institute (SEI) at York, and who leads the GEIC work, said: “While the UK is showing leadership and making strides in monitoring its environmental footprint - the data indicate that the environmental impacts associated with our consumption remain too high and are overwhelmingly felt overseas.”
“Comprehensive environmental accountability involves both the UK and other countries accounting for impacts outside their borders. If we are to meet international biodiversity and climate goals, it is vital that governments, businesses and the public look beyond their domestic environment and economies and consider the total global footprint associated with consumption.”
While long-term data shows a downward trend in the UK’s overall footprint, researchers warn that impacts remain significant and that reductions can reflect a wide range of factors. The UK economy has become more materially-efficient over time which has a positive effect. However, in certain supply chains, such as cocoa from Côte d'Ivoire, footprints are dropping partly because previous historic forest depletion means there is simply less forest left to destroy, rather than due to a transition to purely sustainable practices.
The GEIC indicator is released annually as an official UK statistic. The UK is only one of a handful of countries that have made progress in incorporating consumption-based assessments of deforestation, biodiversity or water impacts into decision-making, despite the impacts of consumption being highly relevant to achieving international commitments linked to climate change and biodiversity loss.
