Plans for 100 'green neighbourhoods' will be laid out today by Hilary Benn, environment secretary, as the government faces criticism for failing to cut carbon emissions from Britain’s old housing stock. Financial Times

Benn will invite areas to enter a national competition to become green neighbourhoods, which would have to commit themselves to rapid cuts of 60% in emissions to help the UK meet its environmental targets. These areas are likely to include old terraced houses, which could benefit from improved insulation and other measures.

The move is part of a package of measures to be announced today, including a new helpline for people who want to make their homes more energy efficient.
