Latest London CO2 reduction target: Getting Planning Permission just got a bit tougher

23 04 2014

In 2005 the Greater London Authority adopted “The Merton Rule”. This planning policy, previously applied by the London Borough of Merton, required developers to offset 10% of the annual predicted CO2 emissions from a new development by using renewable technologies.

In Chapter 5 of London’s response to Climate Change 2011, the Mayor set out his strategy to achieve an overall reduction in London’s CO2 emissions of 60 per cent (below 1990 levels) by 2025.

Year Improvement on 2010 Building Regulations

2010-13 25 per cent

2013-16 40 per cent

2016 –31 Zero carbon

From April 2014, for developments of more than 5 dwellings or 500m2, the London Boroughs have started applying the 40% target. Considering the increasingly stringent Building Regulations, this represents an overall CO2 reduction of c.55% since 2006.

You may have heard of the “Energy Hierarchy”. This approach encourages the designer to wring out energy savings and hence reduce CO2 emissions at every stage.

1. Be Clean: Use less energy

2. Be Mean: Use energy more efficiently, and finally

3. Be Green: Use renewable energy.

The Draft Sustainable Design and Construction SPG provides guidance on suitable techniques to incorporate into your development.

To get Planning Permission the development must meet the latest CO2 emission reduction targets. A detailed Energy Assessment prepared in accordance with GLA guidance on preparing energy assessments will have to be submitted with the Planning Application.

The Stilwell Partnership has been preparing Energy Assessments since the requirement was first introduced in 2005. Over the last 12 months our low carbon solutions have enabled planned developments to meet London’s CO2 emission reduction target and reduce predicted annual CO2 emissions by 300 tonnes.
