Would you paint your roof white to save the planet?
A new scientific study has stated that if the urban environment was designed to be light reflective, it would prevent the atmosphere becoming hot so we wouldn’t feel the need to turn on our air conditioning, which would save the equivalent amount of carbon emission as removing all cars from the roads for 50 years.
The latest scientific experiment has found that white roofs would reflect the sunlight back into space, reducing global warming. Dark coloured buildings, roofs, roads and even pavements attract heat from the sun which causes the land to warm up, sometimes to unbearable temperatures in cities. For an example, Greece has a considerable amount of white buildings, which reflect the sun light therefore prevents them becoming hot during the long summer season.
It is believed that if all cities in the world made their buildings light reflective, it would reduce carbon emissions up to 150 billion tonnes, and that is where the equivalent of taking the world’s cars off the road for 50 years comes from.
Increasing solar reflectance is also known as ‘albedo’ and is measured on a sale of 0 to 1, where 1 is completely reflective and 0 completely absorbs sunlight.
Researchers imply the ‘albedo’ method as being a cheap way of reducing our carbon emissions as light reflective work on buildings could be done routinely, rather than making a special effort.
