London Congestion Charge: Buy 76-100g/km car NOW to get 3 years free of charge

Whether you think the London Congestion Charging Zone is a great way to clean up the air quality of the capital or just another way to tax motorists, you’re going to struggle even more to avoid it after the emission exemption levels are changed on 1st July so only cars emitting 75g/km CO2 or less will be exempt from the charge, Boris says the new lower level is necessary because car makers have worked their socks off to produce small diesel cars with the ability to hit the magic sub 100g/km emissions level in recent years, and that means London is suffering from air pollution as a result. The only answer, apparently, is to drop the limit to 75g/km or less to make those ‘dirty’ diesels pay their way. By reducing the limit to 75g/km you are effectively only allowing EVs and Plug-ins an exemption from congestion charging, thereby moving their emissions off to wherever the electricity they use is produced.
