How Vertical Greening Can Help Alleviate Global Warming

Temperatures in Europe hit new highs this summer. According to an analysis conducted by the Copernicus Climate Change Service (C3S), an organization that aims to support adaptation and mitigation policies of the European Union by providing authoritative information on climate change, June and July this year ranked as the hottest months in recorded history.

Hong Kong, too, has seen temperatures rising. We saw the warmest Lunar New Year on record this year. And in 2018, we witnessed the month of May recording temperatures in excess of 33 degrees for 16 days, the maximum such stretch since the Hong Kong Observatory began keeping records.

The record-breaking warmth has been attributed to global warming. Not only does global warming lead to higher temperatures, it also brings extreme weather that affects people’s livelihood. Last year, super typhoon Mangkhut struck Hong Kong, causing devastation that included loss of more than 40,000 trees.

To mitigate the global warming problem, there is consensus that one of the things that must be done is to expand the urban greening areas. In recent years, Hong Kong has actively expanded its green belts, planted more trees and promoted vertical greening in different districts.

A 250-meter greening wall along Yeung Uk Road in Tsuen Wan has effectively reduced traffic noise and aesthetically improved the environment. Elsewhere, a green wall of the storm water storage tank at the Tai Hang Tung Recreation Playground in Sham Shui Po district has won many design awards, and has become a hotspot for photo shoots.
