repeated with modern evaluation methods. In 2015 road safety campaigner Paul A. Singh and former police Chief Constable Keith Hellawell campaigned for the cessation of British Summer Time after research into Department for Transport data showed that it could lead to a reduction in pedestrian road accidents especially for children. 10:10's "Lighter Later" campaign, in addition to publicising the risk reductions described above, also highlights the potential energy benefits of Single/Double Summer Time, arguing that the change could "save almost 500,000 tonnes of CO2 each year, equivalent to taking 185,000 cars off the road permanently". These proposals are opposed by some farmers and other outdoor workers and by many residents of Scotland and Northern Ireland, as it would mean that in northern Britain and Northern Ireland the winter sunrise would not occur until 10:00 or even later. However, in March 2010, the National Farmers' Union indicated that it was not against Single/Double Summer Time, with many farmers expressing a preference for the change. Other opponents of daylight saving measures say that darker mornings, especially in Scotland, could affect children going to school and people travelling to work. A YouGov poll taken in March 2015 suggested that 40% of the people surveyed would prefer an end to the practice of changing the clocks, while only 33% wanted to keep it (the rest were indifferent or not sure). A recent YouGov survey showed that 44% would prefer to keep changing the clocks as now and 39% backed having constant summertime. 56% were against stopping changing the clocks in Scotland. Sunrise would be as late as 10 a.m. in the winter in northern parts. It is feared that colder icier roads combined with people still half asleep in the dark is bad for health and safety. Current statute and parliamentary attempts at change The current arrangement is now defined by the Summer Time Order 2002 which defines BST as "the period beginning at one o'clock, Greenwich mean time, in the morning of the last Sunday in March and ending at one o'clock, Greenwich mean time, in the morning of the last Sunday in October." This period was stipulated by a directive (2000/84/EC) of the European Parliament which required European countries to implement a common summer time (as originally introduced in 1997, in Directive 97/44/EC). In part because of Britain's longitudinal length, debate emerges most years over the applicability of BST, and the issue
