手机上网看足球赛的碳排放与开车10公里相当

【手机上网看足球赛的碳排放与开车10公里相当】用手机或平板电脑通过3G流量看一场球赛的碳排放比用Wi-Fi信号高10倍;并与以汽油为燃料的汽车行驶10公里所产生的碳排放相当。但是相比于看电视,由于屏幕较小,Wi-Fi信号连接的情况下,比看电视的碳排放小8倍。使用LED屏幕看比赛最节省能源。

Watching TV on a phone using mobile data produces the same carbon emissions as driving 10 miles in a CAR

  • Carbon Trust compared the emissions produced when people stream shows on a mobile phone or tablet
  • It discovered that streaming a football match over 3G had a carbon footprint ten times higher than when the same show is streamed over Wi-Fi
  • This is the equivalent of driving 10 miles in a petrol car

Streaming a football match on a smartphone or tablet using mobile data produces the same amount of carbon emissions as driving a petrol car for 10 miles, claims a new study.

However watching the match when connected to Wi-Fi produces eight times less emissions than when the same sporting event is watched on a television set.

According to figures from the Carbon Trust, the most environmentally-friendly way to watch shows, films and events per viewer is by sharing a screen with other people either at home or in the pub.
Whereas going to see a game live at the stadium produces the most carbon of the lot, particularly for an away game, due to the added impact of transport.

The reports claim watching a match on LED screens is most energy efficient, followed by LCD and then plasma.

It is estimated that this Sunday’s FA Community Shield at Wembley between Manchester United and Wigan will produce 5,160 tonnes of carbon dioxide.

This is the equivalent of the annual energy emissions of around 1,000 homes.

The research found that when watching alone, the lowest carbon way to view football is by using a smartphone or tablet connected to broadband.

Emissions can be as much as eight times lower than watching on television, mostly due to the smaller size of the screen.

In Britain, 27 per cent of smartphone owners and 63 per cent of tablet owners are now using their device to watch live TV.

For the upcoming season both Sky and BT are offering apps that allow football to be watched on personal devices and each device and screen sizes can vary in energy consumption.

However, watching on a plasma screen could result in lifetime emissions a third higher than a similar sized LED television.

A laptop could result in less than half the emissions compared to watching on a desktop computer.

During the 2010-11 season The FA reduced its own carbon footprint by more than seven per cent, compared to 2008-09 and the organisation achieved the Carbon Trust Standard.

Michael Rea, chief operating officer at the Carbon Trust, said: 'Our work helping teams, broadcasters and the telecoms industry to continuously reduce their environmental impact will in turn help to reduce the impacts of fans when they are watching football.'

Roger Maslin, managing director of Wembley Stadium, said: 'We are continuing to find new ways to reduce our environmental impacts.

'Only a small part of the total carbon emissions associated with a game at Wembley are in our direct control, so we are calling on fans to do their bit and help to shrink the carbon bootprint of watching football.'
