After masses of emails, meetings, and organisations lining up to support decarbonisation of our electricity supply, MPs supporting it narrowly lost the vote on Tuesday. The Government's majority was reduced to just 23, so the amendment would have passed if just 12 more Lib Dem backbenchers had voted in line with their party's official position. Seven Tories also followed Tim Yeo's lead and voted for his amendment. Find out how your MP voted below.
The amendment is not yet dead - with such a close vote the Lords will look at it carefully. A Lords rebellion would not necessarily mean that George Osborne would give in and adopt the target, but it could result in a stronger commitment to clean energy than is currently in the bill.
The campaign for clean energy by 2030 has also helped strengthen the climate movement in this country, and we will be working with our allies to build on this momentum.
Thank you to everyone who campaigned so hard over the past months for this.
