Green Infrastructure in Urban Areas

Key Message

The impact of urban heat islands could be decreased by 2.5°C by increasing the amount of green space in town and cities.

Purpose

The information paper provides members of RICS and their clients with background information on the issues surrounding the delivery and promotion of green infrastructure.

Evidence

The impact of urban climate change could be reduced by as much as 2.5°C by increasing the amount of green space in town and cities.

Temperatures in urban areas are currently up to 6°C higher than rural areas and more should be done to alleviate this growing problem.

Current climate change predictions suggest that summer temperatures in the UK may rise by up to 3.5°C by 2050 and urban areas are particularly susceptible. However, by sustainably increasing the amount of green space and planting vegetation on roofs and walls in urban areas, the impact of the ‘urban heat island effect’ could be reduced by as much as 2.5°C.

Green space in towns and cities is being eroded, as playing fields, gardens and general green space increasingly make way for roads and new development. Removing just ten per cent of the green space from a built-up area could see maximum temperatures increase by as much as 7°C.
