This time the plan to separate the borough's car users from yet more of their cash involves charges for 'drop-off' parking permits at local schools.
And once again they seem set on trying to daub this blatant tax hike as 'green'.
Top charge of £75
At the moment, parents can use a free permit provided by schools allowing them to park on double yellow lines or bays for ten minutes while they deliver or collect their children.
So far, so reasonable.
But the council have announced that, from September, a 'sliding scale' will be used to charge parents for these currently free permits, based on the CO2 emissions produced by their vehicles.
The top charge is reportedly going to be an outrageous £75 for dropping your kids off at school in anything from an average-sized family car upwards.
'Green' paint stripped
While the full details of the sliding scale have not yet been revealed (a bit of standard PR that tries to get the headlines out of the way before the gruesome details are exposed), the council's past form makes it likely that the vast majority of parents driving even the smallest cars will have to fork out extra cash where they don't have to currently.
The council's similar emissions-based scheme for residents' parking permits penalises with greatly increased charges those with cars in tax Band D and upwards.
That includes some models of small city cars like the Mini, Ford Fiesta and Nissan Micra. A very different story beyond the oft-used spin about attacking 'gas-guzzling 4x4s', and one that utterly strips away any claim that the scheme is actually about the environment rather than raising cash yet again from soft-target car users.
Sadly, going by the headlines, "4x4s" are the furthest the spin-vulnerable traditional media ever read into such plans.
Scheme condemned as 'unfair'
The council's plan has been roundly condemned by representatives of parent teacher and car user groups.
Margaret Morrissey of the National Confederation of Parent Teacher Associations has called the scheme "unfair and unrealistic", quite rightly pointing out, "Many families have three or four children, and they need the space to fit child seats that the Government insists on."
And the AA's Paul Watters said: "People carriers are very efficient at getting kids to school, considering many are seven-seaters. It might be a better idea to remove the many smaller cars."
Lib Dem warning
As a Liberal Democrat-run council, Richmond's actions give a worrying indication of what sort of faux-green financial repression car users big and small can expect if the Lib Dems achieve any governing power.
Something for us all to bear in mind with local elections looming and even a general election on the horizon.
But spare a thought for the poor car-using residents of Richmond, who clearly face endless demands on their wallets between now and their next local elections in 2010.
Unless they fight back against blatant rip off tax hikes, even when they are labelled 'green'.
