Around 25,000 delegates will descend on Glasgow, UK, for COP26, a climate conference like no other. As a key player at one of the most important climate summits that preceded it, Ed Miliband has a better insight than most on what those people will experience.
Miliband, who is currently shadow business secretary for the UKâs Labour Party, was the nationâs climate minister at the COP15 climate summit in Copenhagen in 2009, which was widely seen as a flop for failing to make a breakthrough on global action to curb emissions.
With 197 countries and blocs party to the UN Framework Convention on Climate Change, which oversees the climate talks, Miliband likens the process to 190-dimensional chess.

âI think people underestimate â and I fear the UK government has underestimated â the complexity of the process,â he says. âItâs not like any other international summit, itâs not coming out with a pre-prepared communiquĂ©. Of course, thereâs been negotiations, but itâs a relatively chaotic process. Itâs a process that requires unanimity.â
He recalls the then UK prime minister Gordon Brown negotiating with other leaders through the night in 2009 to end a deadlock and agree a three-page document, the Copenhagen Accord. âGordonâs parting words for me before he left for London the next morning were, âIâm glad weâve got this, but donât screw it upâ, except he didnât use the words âscrew it upâ.â
But late that day, things went awry. âThat night, as I was going to bed, Pete [Betts, then the UKâs chief climate negotiator] rang me while I was standing in my pants in my hotel room and said âitâs all going down the toilet. The agreement is an empty shellâ.â Miliband, both worried about the geopolitical ramifications and Brownâs reaction, rushed back to the conference centre.
There, he found a Sudanese diplomat giving a speech comparing the accord to the Holocaust. With the UKâs microphone not working, Miliband took the US one to say: âWe canât have come this far and just junk the agreement.â

One infamous moment near the end of the Copenhagen summit was captured in a photo of a stony-faced Barack Obama, Angela Merkel and other world leaders crammed into a small, windowless room. âI was on the edge of that picture, the story of my life,â laughs Miliband, who was leader of Labour when it was defeated at the UKâs 2015 general election. âIt felt quite anarchic. There was very little control over who was and who wasnât in the room. I remember Obama being there and could see him thinking âwhat am I doing thereâ.â
On his overall memory of Copenhagen, Miliband says: âItâs such a blur. My memory is no sleep. Endless meetings.â He recalls nearly running into the then Russian president, Dmitry Medvedev, at one point and asking him if he would increase his climate targets.
âIt sounds a bit anarchic, but thereâs a reason why itâs so difficult. This matters hugely to so many countries and youâre trying to do a really difficult thing [mitigate climate change],â says Miliband.
COP26 faces its own set of challenges, mainly how to put the world more closely on track for the 2015 Paris Agreementâs promise to âpursue effortsâ to hold global warming to 1.5°C and âwell belowâ 2°C. Current government plans would see global emissions rise by 16 per cent by 2030, rather than fall by 45 per cent as is needed for a chance to stay under 1.5°C.
Miliband says: âI think weâre a long way off where we need to be. And I think the truth is weâve got to push as hard as we possibly can to get the 2030 numbers up. But weâve got to tell the truth. This is a question of maths.â
Being honest about the reality of emissions is crucial â not to âcast a downer on everybodyâ, he says, but to remind countries that they should commit to returning as soon as next year with new emissions plans, rather than waiting until 2025 as is currently agreed.
Nonetheless, he doesnât think Glasgow will be a repeat of Copenhagenâs failings. âI donât think itâs comparable to Copenhagen. Weâre not going to have another Copenhagen. The political will, the business will is too strong. Itâs not going to fall apart.â
