I imagine it's for safety and cars run off their batteries. Post Brexit there is an opportunity to make our laws ensure all aspects of travel are more environmentally friendly and world leading.

Will that happen?

Not with this government. Wasted opportunity.

How much does it add to global warming?

So the hundreds of millions of cars in Europe having their lights on all the time emitting heat will not generate a lot of heat! All because some official in the EU decrees it.

That's totally incorrect. Evidence is clear that such schemes all over the world cause changes in behaviour. You're suggesting the congestion charge has had zero impact on volume of vehicles in the congestion zone (in fact you've said numbers have gone up).

Multiple sources report the impact, here is just one:

To suggest otherwise ignores fact. Data shows that the only class of vehicle showing increased activity in CC zone and wider central London and delivery vehicles due to rise in e-commerce, something that can be easily tackled by using delivery hubs around London rather than simply doing single drops offs.

Removing laws and targets set by the EU that require reductions in greenhouse gas emissions and improvements in air quality will definitely make things worse and pretending otherwise is wilful ignorance.

To turn a blind eye to the opportunities will make Brexit a failure.

More needs to be done, not less as this government would like.

Here is this government's priority: [Link]

Wasting our money in a bid to avoid tacking the crisis in air quality and pollution.

I believe the criteria for T-charge is based on a car's "Euro" rating. So has to be at least Euro-4, rising to Euro-6 in a few years to avoid the charge. The Euro ratings are also designed to become more stringent over time.

This demonstrates the issue. We could be more bold by having much better UK car ratings and stopping high polluting vehicles from going into urban areas once we leave the EU. The government could though forget about it and allow dangerous vehicles where they like.

There are huge numbers of schools in London in areas with illegally high and dangerous levels of pollution. These also happen to be schools with higher percentages of free school meals and the report was only recently published, having been suppressed by Boris:

Serious problem, which requires serious solutions. Outside the EU I think we stand at serious risk of it getting worse, but there is real opportunity to make it better.

You need data! Surely a learned chap like you can accept that lights generate heat?
