The Government has made a huge investment in renewable energy and energy efficiency and will continue to do so, Tony Blair has insisted
Mr Blair was responding to a question on climate change during this week's PMQs.
He said the UK had made "dramatic reductions" in its emissions of harmful greenhouse gases and was due to meet and exceed its Kyoto targets.
It was essential though, he went on, that all future measures were "practical and workable".
Last week the PM said a window of just 10 to 15 years remains to take action on global warming before we pass a "catastrophic tipping point".
Mr Blair lent his support to Energy Saving Week yesterday by revealing that he's turned the Downing Street thermostat down by one degree and is using energy-efficient light bulbs throughout Number 10.
