The growing import of goods from abroad instead of manufacturing them here has fuelled an increase in carbon emissions, according to the government's climate change advisers.
Official figures show that Britain's carbon emissions have fallen by around 20% over the last two decades, partly as a result of manufacturing moving overseas. But this data does not include the emissions produced in the making and transportation of goods we import to the UK.
The Committee on Climate Change report found that when emissions 'embedded' in the goods we consume are taken into account, there has actually been a 10% rise since 1993.
The report concludes that official figures should continue to track only the emissions produced within UK borders since this is what other countries do, but that imports should also be monitored.
