The Merton Rule: a review of the practical, environmental and economic effects

10% of energy use from renewable sources

The Merton Rule is the name given to a policy first implemented by the South London Borough Council in 2003, requiring new-build developments to provide 10% of their energy use from renewable sources.

This NHBC Foundation review is an attempt to evaluate the claims of those with differing standpoints, to show which of the various scenarios produce the greatest long-term reduction in emissions, and to assess some practical measures which could be used to achieve these.
