@Jimmy Re: 30m quid on removing greenhouse gases?
You're right, although someone should be factoring in the number of people who can charge at home or at work, as they won't be using public chargers so much. If anyone has stats for the number of people who drive long distances (which for a typical EV is over 100 miles), that would determine roughly how many rapid chargers are needed.
But yes, woeful is the right word to describe the current so-called charging "network".
