Disruption is expected in Central London between Sunday 6 October and Sunday 20 October, as Extinction Rebellion once again take to the streets.
The council is working with the police, Transport for London and other agencies to highlight the impact on residents and businesses.
It is expected that the area around Trafalgar Square, Whitehall and Parliament Square, will experience significant disruption, and bridges may be blocked.
The group have previously come to public attention for obstructing roads and blocking access to buildings, via non-violent civil disobedience.
Increased traffic congestion is highly likely to have an impact on deliveries and refuse collection, but the council will do everything it can to continue business as usual.
We will work with the police to make sure that access for businesses and residents is prioritised and facilitated wherever possible.
Cllr Tim Mitchell, Westminster City Council cabinet member for environment and city management, said: “The right to lawful protest in public spaces is part of our democracy.
“The Metropolitan Police is the lead agency for protests and demonstrations, but we are working closely with them to minimise impact to residents and businesses as much as we can.
“Climate change is a leading concern for our residents. As a council we have already made strides with our environmental campaigns, like #DontBeIdle, the first diesel surcharge, a schools’ clean air fund and more EV infrastructure than other London borough. But there is much more to be done.”
