Next month, the latest annual United Nations climate extravaganza, COP27, will take place in Sharm el-Sheikh, Egypt. Last year it was in Glasgow. Next year it will be held in (drum roll please) … Dubai!
These big climate events have been around a long time. Since 1995, there has been a climate COP (short for “Conference of the Parties”) every year except 2020, when it was postponed due to the Covid pandemic. Over the years, the COP roadshow has traveled far and wide. From Berlin to Buenos Aires, Kyoto to Cancun, and Bali to Marrakesh, the COPs have criss-crossed the globe with the aim of finessing new agreements to see off the specter of climate change.
These annual summits generate a lot of interest. The most recent in Glasgow attracted tens of thousands of participants. World leaders and celebrities often jet in and join the throng, while the global media reports every move in the corridors of power and concerned citizens protest outside. And yet the COPs are only the tip of the proverbial iceberg when it comes to UN-sponsored climate meetings.
If you add the several preparatory meetings in the lead-up to the COPs, plus a host of workshops and other events by various expert technical groups, you’re easily looking at several dozen gatherings every year.
Each event is supposed to help us move the needle on climate change, keeping our warming world within the 1.5°Celsius threshold beyond which we face potentially catastrophic consequences. But what, exactly, do all of these many meetings accomplish? Are they really worth all this time and effort?
There are plenty of arguments against letting the climate circus continue its endless circuit. For a start, science tells us that in spite of all the many meetings held, we’re still on a dangerous path. Groups like Carbon Action Tracker estimate that we’re currently on track for somewhere between 1.8-2.7°C, with the lower number representing their most optimistic—and least likely—scenario. This is clearly well above where we need to be.
Another common complaint is that UN climate COPs are mostly just talking shops; in Greta Thunberg’s words, too much “blah, blah, blah” and not enough action. For all the millions, even billions, of words uttered at these events, they can often end in acrimony with little of substance agreed. Surely, the money used to hold these summits could be better spent on something else?
Even when agreement is reached, say the critics, there is no guarantee governments and other stakeholders will keep their pledges. History is littered with broken promises and diplomatic treaties that aren’t worth the paper they’re written on.
These arguments are all credible and we don’t disagree with any of them. But here’s the thing. For all their weaknesses and flaws, these summits actually matter a lot.
First, the United Nations climate process has definitely moved the needle when it comes to our response to climate change. When the UN climate treaty was first signed in 1992, it triggered a wave of national laws, policies, and regulations that have rippled out across every country on earth. This process has started to shift almost every aspect of our modern economic system away from 200 years of reliance on fossil fuels.
Take our global energy systems, for instance. From being a niche market in the 1990s that could not compete on cost with coal, oil and gas-generated electricity, in 2020 solar power became the cheapest source of electricity in history. The technology behind both solar and wind have moved on in leaps and bounds since the 1990s, thanks in large part to the flow-on effects of international lawmaking.
The much-maligned Kyoto Protocol of 1997, now largely superseded by the 2015 Paris Agreement, brought the private sector firmly into the equation, launching carbon markets and spurring private sector investment that has begun to reshape our global economy away from its reliance on fossil fuels.
From electric vehicles to power generation to building design, the number of changes catalyzed by our international work on climate change are too many too list. Probably the best metric for judging the UN climate summits, however, is their impact on long-term global warming.
In recent years, projections for the expected long-term warming have fallen from as much as 4-6°C before the Paris Agreement was inked, to around 1.8-2.7°C now, assuming we implement pledges made at UN summits. And while anything above 1.5°C is still very, very bad and the need for more action remains urgent, it’s not as unimaginably catastrophic as those higher numbers would be.
That’s not to say the UN climate process can’t be improved. Some people would like to see them shrunk back to their size in the early days, when just a couple of thousand people—key negotiators and a smaller number of other stakeholders—met in person. This, they say, would render it more manageable, reduce the carbon footprint, and make it less of a “circus.”
