After two hard-fought weeks of negotiations, the Glasgow climate change summit is, at last, over. All 197 participating countries adopted the so-called Glasgow Climate Pact, despite an 11th hour intervention by India in which the final agreement was watered down from “phasing out” coal to “phasing down”.
In an emotional final speech, COP26 president Alok Sharma apologised for this last-minute change. His apology goes to the heart of the goals of COP26 in Glasgow: the hope it would deliver outcomes matching the urgent “code red” action needed to achieve the Paris Agreement target.
At the summit’s outset, UN Secretary-General António Guterres to “keep the goal of 1.5℃ alive”, to accelerate the decarbonisation of the global economy, and to phase out coal.
The goal of the Paris Agreement is to limit global temperature rise to well below 2℃ this century, and to pursue efforts to limit warming to 1.5℃. Catastrophic impacts will be unleashed beyond this point, such as sea level rise and more intense and frequent natural disasters.
Despite the Australian government’s recent climate , this nation’s 2030 target as in 2015. If all countries meagre near-term targets, global temperature rise would be on track for up to 3℃.
Technically, the 1.5℃ limit is still within reach because, under the Glasgow pact, countries are asked to update their 2030 targets in a year’s time. However, as Sharma said, “the pulse of 1.5 is weak”.
India is the world’s emitter of greenhouse gases, after China and the United States. The country relies heavily on coal, and coal-powered generation is expected to each year to 2024. India was the most prominent objector to the “phase out” wording, but also had support from China.
And US climate envoy argued that carbon capture and storage technology could be developed further, to trap emissions at the source and store them underground.
Carbon capture and storage is a controversial proposition for climate action. It is not proven at scale, and if captured emissions stored underground will eventually return to the atmosphere. And around the world, large-scale underground storage locations exist.
And it’s hard to see this expensive technology ever being cost-competitive with renewable energy.
Despite the shortcomings, COP26 led to a number of important positive outcomes.
The world has taken an unambiguous turn away from fossil fuel as a source of energy. And the 1.5℃ global warming target has taken centre stage, with the recognition that reaching this target will require rapid, deep and sustained emissions reductions of , relative to 2010 levels.
What’s more, the pact emphasises the importance to mitigation of nature and ecosystems, including protecting forests and biodiversity. This comes on top of a side deal struck by Australia and 123 other countries promising to end deforestation by 2030.
Nations are also invited to revisit and strengthen the 2030 targets as necessary to align with the Paris Agreement temperature goal by the end of 2022. In support of this, it was to hold a high-level ministerial roundtable meeting each year focused on raising ambition out to 2030.
The is also cause for cautious optimism.
Despite the world not being on track for the 1.5℃ goal, momentum is headed in the right direction. And the mere fact that a reduction in coal use was directly addressed in the final text signals change may be possible. But whether it comes in the small window we have left to stop catastrophic climate change remains to be seen.
