Take the pledge to wash at 30°

Did you know that washing at 40° uses more than double the amount of energy than washing at 30° and yet more than half of British households are keeping their washing machines running at high temperatures?

Last year, research carried out by Ariel and the Energy Saving Trust revealed that 60% of British households, in pursuit of whiter whites and stain free clothes, are keeping their washing machines running at high 40° temperatures, using more than double the energy needed for doing laundry. Despite huge improvements by detergent makers to enable washing at cold temperatures, homeowners are still using more than double the energy needed for doing laundry at 40° compared to a cold wash (lower than 30°).

For every pledge made, Ariel will donate £1

To try and help change this, Ariel is supporting our Earth Hour pledges, where we ask people to change one thing in their everyday lives that will help protect our planet. They’ll be supporting a pledge to wash at 30° and will be generously donating £1 to WWF for every pledge made online using the #EarthHourUK hashtag or via our website from 5th March, up to a value of £145,000.

Washing at 30° is a simple way to save a considerable amount of energy and reduce our carbon footprints. Just to give you an idea, if every household in the UK turned their washing from 40° to 30° for one year, it would save CO2 emissions equivalent to powering 1550 homes for an entire year.  And if every household in Greater London switched from 40° to 30° throughout the year, they could save enough energy to rotate the London Eye 2.3 million times.

Use your #VoiceForThePlanet

Your pledge might seem fairly small individually, but as this shows, millions of people taking these actions together will have powerful impact. To use your #VoiceForThePlanet and make a pledge please click here.

While you don’t need to buy P&G products to take part in the campaign, Ariel is helping us reach millions of people and draw attention to critical environmental issues. WWF has been working with P&G since 2008 in the US, where WWF-US has been helping P&G reduce the impacts of its operations on the environment.
