The Prime Minister will reportedly announce a "Plan for motorists" on Monday, which includes allowing cars the greater use of bus lanes.
The Government has announced £80m of funding for the sector through Bus Service Improvement Plans+.
Representatives from Stagecoach East, Dews Coaches, A2B and Whippet joined together with trade association CPT to highlight that if everyone switched just one car journey a month to bus, there would be a billion fewer car journeys and a saving of 2 million tonnes of carbon dioxide per year.
