ساعت 20:30 به وقت محلی روز سی و یکم مارس مصادف با 12 فروردین ساعت خاصی بود که به "ساعت زمین" معروف بود. در این لحظه بنا بود در حرکتی نمادین یک ساعت کلیه وسایل برقی خاموش شوند تا به این ترتیب به کنترل گرمایش زمین و تغییر اقلیم کمکی شود.
این حرکت را صندوق جهانی حمایت از طبیعت (World Wide Fund for Nature (WWF)) در سال 2007 مطرح نمود که از سال 2010 هم سازمان ملل به آن حرکت پیوست و یک ساعت کلیه وسایل برقی خاموش شدند. در سال جاری 135 کشور و 5200 شهر در این حرکت مشارکت نمودند.
اما به راستی با یک ساعت خاموش کردن وسایل برقی می شود به فکر محیط زیست بود!!
SPOTLIGHTING SUSTAINABILITY, THE UN GOES DARK FOR EARTH HOUR 2012
New York, Mar 31 2012 3:05PM
The United Nations will today turn off the lights for one hour at its Headquarters in New York and other facilities around the world in observance of “Earth Hour”, an annual global event that seeks to raise awareness on the need to take action on climate change.
Secretary-General Ban Ki-moon said in a statement that the UN was turning off its lights “in solidarity with men, women and children – 20 per cent of all humankind – who live with no access to electricity.”
Mr. Ban, who in September launched an initiative to achieve universal and sustainable access to this vital resource, called Earth Hour “a symbol of our commitment to sustainable energy for all,” and underscored the need to “fuel our future with clean, efficient and affordable energy.”
Earth Hour, launched in 2007 in Australia by the World Wide Fund for Nature (WWF), calls for people, organizations and cities to turn off their non-essential light for one hour starting at 8:30 p.m. local time.
This is the third year that the United Nations joins hundreds of millions of people around the world in switching off the lights. Last year, more than 5,200 cities and towns in 135 countries participated in the event.
While the actual hour is a symbolic call to action on climate change and not intended as an energy-saving measure, event organizers are asking people to “go beyond the hour” and take meaningful steps to reduce their energy consumption after the light go back on.
Secretary-General of the UN Sustainable Development conference (Rio+20) that will take place this June in Brazil, Sha Zukang, said Earth Hour is an event that helps people think about the need to take actions that promote sustainable development.
“We cannot continue business as usual. We need to rethink the way we use our resources, how we promote well-being and protect the environment. We need to pursue new ideas,” Mr. Zukang said.
On Saturday, March 31 at 8:30pm EST, hundreds of millions of people, businesses, and governments around the world will unite to celebrate Earth Hour by switching off lighting and electronics to raise awareness for climate change and other sustainability issues.
Earth Hour is an event organized by the World Wildlife Fund and is considered the largest environmental event in history. Hundreds of millions of people, businesses, and governments around the world unite to switch off lighting and electronics to raise awareness for climate change and other sustainability issues.
The GEF – as one of the largest public funders of climate change projects – is inviting you to join our GEF secretariat staff by switching off your computers, monitors, printers, other electronics and office lights at work before you are leaving for the weekend. At home, on Saturday evening the only thing you have to do to be part of the environmentally sensitive global community is to switch off your lights for one hour. It's an easy, energy-saving signal to the world.
We will do it, and we are counting on you to do it too....
Last year, more than 5,200 cities and towns in 135 countries participated by switching off their lights ––sending a powerful message for action on climate change. During previous Earth Hours, the lights have been turned out at iconic landmarks such as the Eiffel Tower and the Giza Pyramids, as well as in major cities such as Sydney, Australia, and Toronto, Canada.

For the GEF, it's more than an hour, it's part of its 20 year old mandate: The GEF/UNEP en.lighten initiative is one good example for that.
Electricity for lighting accounts for almost 20% of electricity consumption and 6% of CO2 emissions worldwide. If not addressed immediately, global energy consumption for lighting will grow by 60% by the year 2030. If all developing and emerging countries join the en.lighten initiative, CO2 emissions from lighting can be reduced by almost half.
The phase-out of inefficient incandescent lamps and their replacement with higher efficiency light bulbs, such as light emitting diodes (LEDs) or compact fluorescent lamps (CFLs), is one of the easiest and most cost effective ways to significantly reduce carbon emissions. The UN Environment Programme (UNEP) /Global Environment Facility (GEF) en.lighten initiative has been established as a globally coordinated effort to accelerate the transition to efficient lighting to reduce the threat of global climate change.
Despite improvements in technology and the looming climate threat, most developing and emerging countries around the world have not taken steps towards the switch to energy efficient lighting. Making the transition would significantly impact the ability to use existing power without having to build new and expensive generation facilities. For example, India would be able to provide power to 35 million homes, and South Africa to 4 million homes, from the electricity saved from replacing all existing incandescent lamps with energy efficient alternatives.
En.lighten is a top prioritty for lighting industry leaders Philips and Osram Sylvania who are providing substantial technical and financial resources to promote this effort.
En.lighten and its partners have targeted 2016 for the global phase-out of inefficient lighting products. Providing expert technical and policy guidance to countries will help to meet this date and ensure that replacement bulbs meet global quality standards and that used bulbs are disposed of in an environmentally sound way. So far, a total of 30 countries from four continents have joined the Global Partnership Program and more countries are expected to join soon, with your help.
So take the challenge now! Show your support for the switch to energy efficient lighting to reduce the threat of global climate change and improve the quality of life for people. Everyone around the world should be able to look forward to a brighter and more sustainable future.
It's as easy as turning off your lights during Earth hour. Then let that be a reminder to replace any inefficient light bulbs with new efficient ones!
