LONDON-The UK will not meet its climate change targets without a revolution in home heating, a think tank says.

A report from the cross-party Policy Connect says gas central heating boilers also threaten the UK’s clean air goals.

But a poll conducted among MPs suggests that most do not consider pollution from home heating to be a priority.

That is despite the fact 14% of UK greenhouse gases come from our homes, a similar level to emissions from cars. In major cities gas boilers are also a main source of nitrogen dioxide emissions.

The government wants low-carbon heat systems to be standard for all new homes built after 2025.

But that will still leave the vast majority of existing homes in the UK with polluting heat systems.

A spokesman for the Treasury said a plan to support the move to sustainable heating systems would go out to consultation later this year.
