Rigorous research undertaken by Manchester University demonstrated that a 10% increase in a capital city's tree cover would reduce a city's surface temperature by as much as 3-40 Celsius.

In response to this data, and as part of the London Plan - Spatial Development Strategy, a programme of street tree planting is now underway across London. This important aspect of the urban greening programme means that, over the next forty years, millions of trees will be planted in London's streets.

Whilst doing this it has been decided to test out a range of urban greening programmes. The resultant variations in temperature reduction outcomes will be noted so as to identify the optimum regime to adopt.

As a consequence of this programme it can be clearly seen that street tree planting counteracts the impact of climate change.
