Online marketplace eBay and the Environment Agency (EA) have collaborated to remove adverts for vehicle parts – such as catalytic converters – from sellers who do not hold the necessary permits.
The clampdown saw 10 traders suspected of selling without the correct permissions being suspended. Over half of those sellers then applied for the correct permits.
The Vehicle Recyclers’ Association (VRA) said there were ‘hotpots’ of illegal sellers in Yorkshire, the West Midlands and Lancashire.
Police forces across the UK have also been alarmed by a rise in the theft of catalytic converters.
eBay said it is contacting around 20,000 active sellers to encourage them to trade legally. It is also requiring traders to display EA permit numbers when listing second-hand car parts.
