“The deal’s dead.” These have been the words of my chief negotiator, roughly six years ago, in the middle of the night in the final hours of the sleep-deprived Copenhagen summit. I was standing in my bedroom as I took his call, about to go to bed for the initial time in 36 hours. Thanks to the efforts of a quantity of nations into the night and the subsequent day, it turned out the deal wasn’t really dead, and one thing did survive.

But in truth, it is what has happened in the years after Copenhagen that produced it not fairly the disaster it appeared at the time. Slowly, steadily, the unwieldy, spatchcock UN process has rumbled on. Lessons have been learned from that chaotic episode. The concept that we must construct an agreement bottom-up with nations creating person pledges, first conceived at Copenhagen, has turn into more severe, and every single massive emitter has place a single forward.
And now we approach next week’s Paris climate talks, the most essential summit considering that Copenhagen, in a drastically far better location than we feared back in 2009. However, we are not where we want to be.
The science is even much more unequivocal than it was six years ago. Just to take one example, 2015 appears like being the hottest year on record by some distance. We at times speak about the need to stay away from unsafe warming of the planet as if it is a theoretical notion, but its effects are already here, with approaching 1 degree of warming so far.
On the other side of the ledger, technologies has thrown us a lifeline. The expenses of wind and solar energy have come down far faster than anyone dreamed of. The constructive side of human ingenuity is holding its personal in the fight against its destructive side. And it is now demonstrably the case that the fight against climate alter can be job-creating, not destroying, according to the Confederation of British Business and numerous other individuals.

And what about political will? Climate adjust seems much less politically fashionable as an issue. But China and the United States have moved forward a lengthy way from exactly where they had been at Copenhagen.
We have moved from a planet where everybody stated it was an individual else’s problem, to one particular where every person knows this can be only be solved collectively. We are not in a globe of enterprise as usual.
That is the very good news. And in many senses the Paris summit appears set to represent success: each significant nation taking genuine action to reduce emissions, a substantially various path from where we would be without that action. Paris will also repeat the international commitment produced at Copenhagen to limit warming to 2 degrees.
But the bad news is that the pledges will nevertheless be quick of what is needed. In reality, the commitments for 2030 would take us towards something like a three-degree globe. That would imply larger temperatures than at any time in the final three million years, with potentially dramatic effects of intense heatwaves, flooding and climate refugees across the globe.
So what can be done? Just like at Copenhagen, what matters as much as Paris is what occurs afterwards. That is why nations are rightly searching for to build an upwards ratchet mechanism into the agreement. If these pledges are the start, not the final word – a prelude to higher ambition – then we can nevertheless keep away from the most unsafe effects of international warming.
What does this imply for Britain? The final Labour government introduced the Climate Adjust Act, with all-party support for an 80% reduction in emissions by 2050 – the initial nation in the world to legislate for such deep, lengthy-term cuts. It is vital we stay on track for this objective, including creating the appropriate decisions about the period to 2030 which will face the government in the coming months.
But what the science now tells us is that we will need to go additional and see a full finish to the accumulation of further greenhouse gases in our atmosphere. The globe will need to have to move to zero emissions at some time in the second half of the century, as President Obama and the other G7 leaders, like David Cameron, have rightly acknowledged. A point will come when the total carbon budget for the planet will basically be utilized up.
Paris need to be the start of a journey of the whole world towards this objective
And right here is the relevance as far as Paris is concerned: every single excess tonne of carbon we emit among now and 2030 brings the date when we need to have to get to “net zero” emissions forward – the point at which any remaining emissions are balanced out by the capturing of carbon.
Is zero emissions even practical, and can it be completed without closing down our economy? The answer to each queries is a powerful yes. Certainly, top company leaders such as Ratan Tata as effectively as Paul Polman of Unilever have lately called on globe leaders to adopt a zero emissions purpose in Paris.
So how can it be carried out in the UK? It is about a one hundred% clean power supply. It is about creating our power system a lot more efficient and productive. It is about the proper infrastructure. And, to cancel out residual emissions from agriculture and business, it is about capturing carbon from the atmosphere, for instance via reforestation and by the use of carbon capture and storage technology.
Currently cities and businesses are adopting the zero emissions objective. The appropriate step now would be for Britain to become the very first main nation to enshrine net zero emissions in law, with the date determined by advice from the independent Committee on Climate Change.

This would be consistent with the government’s help for zero emissions at G7 level and would show our determination to face up to this existential challenge. It will supply an essential framework for company and government so that we make the appropriate decisions now on key power and infrastructure issues. And it will inspire the inventors, engineers and companies that can provide on this challenge.
From my conversations with folks across the Home of Commons, like the Liberal Democrats, the SNP, Caroline Lucas of the Greens and Conservatives such as Nick Hurd and Graham Stuart (chair of Globe, the international parliamentarians group on climate alter), it is clear there is cross-party assistance.
Paris must be the begin of a journey of the whole globe towards this purpose. And far from this commitment holding Britain back, we can be a leader once more on climate alter. Leadership which does not mean harm to our economy, but will put us ahead in the race for the new jobs, firms and benefits of this new planet.
I hope the government will support this initiative. We can construct an alliance, place aside our celebration differences as we have before, and seize this moment.
