2035 climate pledges
Belém was supposed to be a celebration of ambitious new emissions pledges which would keep alive the Paris Agreement goal of holding warming to 1.5°C. Nations were originally due to submit their 2035 pledges (formally known as Nationally Determined Contributions) by February, with an extension given to September after 95 per cent of countries missed the deadline.
When pledges finally arrived in September, they were broadly underwhelming. Only half the world’s emissions were covered by a 2035 pledge, meaning the remaining emissions gap could be very significant. Australia is pledging cuts of 62–70 per cent from 2005 emissions levels.
That’s not to say there’s no progress. A new UN report suggests countries are bending the curve downward on emissions but at a far slower pace than is needed.
How negotiators handle this emissions gap will be a litmus test for whether countries are taking their Paris Agreement obligations seriously.
Rise of the courts
Even as some countries back away from climate action, courts are increasingly stepping into the breach. This year, the International Court of Justice issued a rousing Advisory Opinion on states’ climate obligations under international law, including that national targets have to make an adequate contribution to meeting the Paris Agreement’s temperature goal. The court warned failing to take “appropriate action” to safeguard the climate system from fossil fuel emissions — including from projects carried out by private corporations — may be “an internationally wrongful act”. That is, they could attract international liability.
It will be interesting to see how this ruling affects negotiating positions at COP30 over the fossil fuel phase-out. At COP28 in 2023, nations promised to begin “transitioning away from fossil fuels in energy systems”. If countries fail to progress the phase-out, accountability could instead be delivered via the courts. A new judgement in France found the net zero targets of oil and gas majors amount to greenwashing, while lawsuits aimed at making big carbon polluters liable for climate damage caused by their emissions are in the pipeline.
An Australia/Pacific COP?
A big question to be resolved is whether Australia’s long-running bid to host next year’s COP in Adelaide will get up. The bid to jointly host COP31 with Pacific nations has strong international support, but the rival bidder, Turkey, has not withdrawn.
If consensus is not reached at COP30, the host city would default back to Bonn in Germany, where the UN climate secretariat is based.
Outcome unknown
As climate change worsens, these sprawling, intense meetings may not seem like a solution. But despite headwinds and backsliding, they are essential. The world has made progress on climate change since 2015, due in large part to the Paris Agreement. What’s needed now on its tenth anniversary is a reinfusion of vigour to get the job done.
