As we’ve been arguing here since March, the year that policymakers select as the deadline for global emissions must peak is the key short-term variable to watch at Copenhagen. So what is the deadline, assuming we want to limit global average warming to 2 degrees C?
Well, David and I would like to see policymakers agree that emissions should peak right now, given that emissions have fallen so much as a result of the credit crunch. The development NGOs who are most active on climate change – Oxfam, Christian Aid and Tearfund, as well as Avaaz – are a little more cautious than that, arguing that emissions should peak by 2015; but they’re still basically on the same page as the IPCC, which said in its last Assessment Report (pdf - see table at the foot of page 15) that to limit global average warming between 2.0 and 2.4 degrees Celsius, global emissions must peak between 2000 and 2015. Chair of the IPCC Rajendra Pachauri has also said that 2015 is the deadline.
Astonishingly, though, the main federation of environmental NGOs – the Climate Action Network – says that any time up to 2017 is fine. WWF International agree. TckTckTck used to say 2017 too (as I noted when they published their policy position); they’ve subsequently revised their target to 2015, but still have documents on their website using the old date. (Nothing like a consistent message, eh?)
Be very clear: this isn’t just hair-splitting. Once the peak date for emissions slides beyond 2015 and towards 2020, according to the IPCC, we’re heading for a world that’s not 2.0-2.4 degrees C warmer, but 2.4-2.8 degrees C. That is what the environmental NGOs are arguing for. Shortly before they spend a fortnight calling everyone else at the Copenhagen summit “fossil of the day“. It’s breathtaking.
So, if you can’t make it to the summit but still want a way to take action and make your voice heard ahead of Copenhagen, how about this. First thing on Monday, get in touch with any environmental NGOs you support. Ask them their position on the global peak emissions date. And if it’s any later than 2015, then cancel your subscription.
I’m not kidding. Policymakers aren’t the only ones at Copenhagen who need to be held to account. If the green NGOs can’t get their figures right on something this fundamental, this basic (even as the development NGOs manage it just fine) then they need to – what’s that phrase from the Bali summit? – “leave it to the rest of us; please, get out of the way“.
