One must know whom to trust

Sir, – To be fair, Dr Charles Wardrop now presents a more reasonable position (Letters, October 29).

However, he describes the health effects of vehicle pollution as just conjecture.

I prefer the opinions of professors of environmental health, toxicology, paediatrics respiratory and environmental medicine, public health experts, data scientists and statistical professionals, all of whom are on the committee on the medical effects of air pollution (COMEAP), that officially advises the UK Government.

They are, if anything, likely to be conservative in their opinions.

There are also the judges of the UK Supreme Court who have adjudicated that the UK Government is in breach of the law on this issue.

Whether a ban on cars is the right thing to do is not something I have said. I did notice this appeared to be the editorial position taken by the New Scientist.

I would say that the UK Government’s decision to now reduce incentives for the least polluting cars is just perverse.

I do agree with Charles Wardrop’s concern about the hazards of cycling.

It doesn’t help that Scottish Government planning guidance is directly contrary to robust, peer reviewed, journal published science on this issue.
