In the effort to slow the pace of global warming, researchers and policy makers are encouraging the use of lighter colors for rooftops and streets worldwide. Dark, non-reflective surfaces which are common for asphalt and asphalt shingles, absorb heat from the sun and create a "heat-island" effect, plus a greater need for air conditioning. Lighter surfaces would reflect the sun’s rays back to outer space, reducing ground-surface temperatures and overall energy requirements.

Trees a 'low-cost' solution to air pollution and biodiversity loss in cities

Editor, Ecologist
Native woods and trees in urban areas, including gardens, provide haven for wildlife, reduce air pollution, surface run-off and flooding Reversing the declining numbers of native trees and woods in cities would provide numerous benefits at 'relatively little cost', says a report from the Woodland Trust. As well as access to green space, the report, 'Greening the Concrete Jungle', says trees provide a wide range of free ecosystem services including reducing the risk of surface water flooding and improving air quality that could save millions in flood defence and healthcare costs.

The results were overwhelmingly positive, so we are glad to know we are doing a pretty good job. Of course, there is always room for improvement.
