Design of skyscraper cities leads to more pollution, says study

City pollution is soaring in summer because vast swathes of paving and brick retain too much heat at nigh, and tall buildings block the cooling winds that should clear airborne pollutants, researchers say.

Town planners across the world must change tactics to improve air quality, according to the report by the National Center for Atmospheric Research. Greener cities with more lakes and ponds would have less pollution, even if carbon dioxide emissions from cars and homes stayed the same, said the US group.

‘The night-time temperature would be lower and winds would become stronger, blowing the pollution out to sea,’ it added.

The international study was held to examine reports of falling air quality in fast-growing cities, particularly those near coasts. The key reason was found to be manmade – but not the usual suspects of global warming and increasing CO2 emissions. Instead, the paving over of green spaces and bigger building projects was blamed.

In Houston, Texas, for example, ‘the developed area has a major impact on local air pollution’, said the group. ‘If the city continues to expand, it is going to make the winds even weaker in the summertime and that will make air pollution much worse,’ the report added.

Houston’s authorities have tried to tackle air pollution with strict carbon dioxide emission targets. Other cities have taken similar steps, including London with its congestion zone and bike hire scheme.

However, the capital is also building its tallest skyscraper, the Shard. The report will be published in the Journal of Geophysical Research later this month.

I completely agree with you. Especially in Western countries, where skyscrapers are planned to be environmentally sustainable.

I posted the article but it doesn't mean I agree with it.

It's good the Shard is starting to be associated with London.

Ideally we should have high density development with skyscrpapers and a lot of green space around. But that never happens. It's always every square inch of ground covered then high rises added on top of that.
Cities are heat islands. The only way to help is to plant thousands of trees that specifically will thrive in an urban environment.
Certain trees are also amazing at negating polution.
In the American South standing under a Live Oak can be like being in air conditioning. But they obviously won't grow in the UK.

I am fortunate to live in Charleston, SC which is on the Atlantic Ocean and has a very large harbor with 3 Rivers surround it.(water temp can be 86-90 degrees!)
In the Summer it is 5 degrees(fahrenheit) cooler than 10 miles inland, because of the harbor. But at night it can be 5 degrees warmer because the ocean temps keep the city warmer. ie: 100 degrees inland, 95 degrees in the city during the day. visa versa at night.
We also have a beachhouse house on a nearby island and it can be 10 degrees cooler than inland, but at night it can be brutally hot and unbearable.
We have had nights where the temp never dropped below 86 degrees.
And our front yard(ocean side) can be 5 degrees cooler than our backyard.
We have mitigated the temp in our backyard by planting trees.

It is interesting how many microclimates there can be in not just a few miles, but even a hundred feet.

From the junction of Druid Street and Tower Bridge Road, messing about with another £25 eBay lens - a Canon FD 135mm f/2.5
