The Government will slash the distance of car journeys and clamp down on parking spaces as part of its climate action plan, it is understood.
The plan, which will set out how the Government will achieve the agreed sectoral emissions targets and the overall target of a 51% reduction by 2030 and net zero by 2050, will be published on Wednesday.
The Cabinet will meet on Wednesday afternoon to sign off on the plan.
While it is understood there is no specific commitment to congestion charges within the plan, the Government is considering them as one of their options.
They would only be brought in where there are viable alternatives to cars, including good public transport and active travel.
