The campaign to move the UK's clocks forward by one hour, slashing national carbon emissions in the process, could take a major step forward today with the latest parliamentary vote on the proposed Daylight Savings Bill.

The bill, which was tabled by Rebecca Harris MP, has secured significant cross-party support and was first passed by the House of Commons in late 2010.

It subsequently passed through the committee stage with a number of amendments and is today scheduled to move to a full vote. If, as expected, the bill succeeds at its third hearing today it will then pass to the Lords for debate.

The bill would require a full independent review of the impact of moving the clocks forward by one hour. If the review concludes that changing the clocks would be beneficial the government would then order a three-year trial, subject to approval from the devolved administrations of Scotland, Wales, and Northern Ireland.

Proposals to change the clocks have been advanced several times over the past few decades, with environmental groups consistently supporting a plan that according to research could help cut carbon emissions by 500,000 tonnes by reducing the need for electric lighting and lowering peak energy demands.

However, the proposals have never before reached such an advanced stage and campaigners are increasingly confident a trial could be approved by 2015.

Betting experts Ladbrokes today shortened odds for the clocks being changed within three years to ½, making it the first time that the campaign has been odds on to succeed.

The Lighter Later campaign has been driven by the 10:10 group, which has secured the support of a wide coalition of MPs and business leaders, significantly including a number of Scottish groups that in the past have opposed the proposed changes.

All the UK's major road safety organisations have signalled their support for the plan, while the tourism and hospitality industry has estimated that lighter evenings could create up to 80,000 jobs and deliver a £3bn boost to the economy.

Daniel Vockins, campaign manager at 10:10, said that support was growing for the proposed changes.

"The old arguments about milkmen and postal workers needing early-morning sunlight to carry out deliveries are outdated and the move is no longer opposed by these groups," he said. "We need to realign the clocks with the way modern Britain actually lives. More jobs, better sporting opportunities, safer roads and lower carbon emissions are what we need right now. Here's a policy with broad public support that ticks all those boxes and costs virtually nothing to implement. It's a complete no brainer."
