We requested specialists from world wide for his or her response to the end result of this yr’s UN local weather summit, COP26, together with the Glasgow Local weather Pact agreed by all 197 nations attending the talks. Right here’s what they needed to say in regards to the offers that had been made. (This web page can be up to date as extra reactions are available in.)
Offers and targets
A place to begin for future motion.
The summit was pitched because the final probability to “preserve 1.5°C alive” – holding temperatures to lower than 1.5°C above their pre-industrial ranges. 2020 was additionally supposed be the yr when developed nations would supply a minimum of US$100 billion a yr of monetary help to assist creating nations adapt to mounting storms and droughts, and the transition to wash power was supposed to start out being rolled out.
Maybe involved that nationwide targets collectively had been nowhere close to ok to maintain 1.5°C alive – we had been heading for extra like 2.4°C at finest – the UK authorities used its presidency programme to complement these targets with a collection of press-friendly bulletins of non-binding pledges to chop methane emissions, finish deforestation and part out coal.
These had been additional supplemented by the “race to zero” initiatives, a collection of bulletins by states, cities and companies on a spread of decarbonisation approaches.
Whereas these are real makes an attempt at local weather motion, success hinges on whether or not these developments can swiftly make into raised nationwide commitments inside the subsequent yr.

Greenhouse gasoline emissions
Progress on chopping emissions, however nowhere close to sufficient.
The Glasgow Local weather Pact is incremental progress and never the breakthrough second wanted to curb the worst impacts of local weather change. The UK authorities as host and subsequently president of COP26 needed to “preserve 1.5°C alive”, the stronger aim of the Paris Settlement. However at finest we are able to say the aim of limiting international warming to 1.5°C is on life assist – it has a pulse nevertheless it’s practically lifeless.
The Paris Settlement says temperatures needs to be restricted to “properly beneath” 2°C above pre-industrial ranges, and nations ought to “pursue efforts” to restrict warming to 1.5°C. Earlier than COP26, the world was on monitor for two.7°C of warming, based mostly on commitments by nations, and expectation of the modifications in know-how. Bulletins at COP26, together with new pledges to chop emissions this decade, by some key nations, have lowered this to a finest estimate of two.4°C.
Extra nations additionally introduced long-term web zero targets. One of the crucial essential was India’s pledge to succeed in web zero emissions by 2070. Critically, the nation stated it might get off to a fast begin with an enormous enlargement of renewable power within the subsequent ten years in order that it accounts for 50% of its complete utilization, lowering its emissions in 2030 by 1 billion tonnes (from a present complete of round 2.5 billion).
A world warming by 2.4°C continues to be clearly very removed from 1.5°C. What stays is a near-term emissions hole, as international emissions look prone to flatline this decade reasonably than displaying the sharp cuts essential to be on the 1.5°C trajectory the pact requires. There’s a gulf between long-term web zero targets and plans to ship emissions cuts this decade.

5 issues you’ll want to know in regards to the Glasgow Local weather Pact
Fossil gas finance
Some progress on ending subsidies, however the remaining deal fell brief.
An important outcomes from COP26 can be straight associated to 2 “F-words”: finance and fossil fuels. Shut consideration needs to be paid to pledges for brand new finance for mitigation, adaptation, and loss and harm. However we should bear in mind the opposite facet of the equation — the pressing want to chop off funding for fossil gas initiatives. Because the Worldwide Power Company made clear earlier this yr, there isn’t any room within the 1.5℃ carbon funds for any new investments in fossil fuels.
The dedication from greater than 25 nations to close off new worldwide finance for fossil gas initiatives by the tip of 2022 is without doubt one of the greatest successes to come back out of Glasgow. This might shift greater than US$24 billion a yr of public funds out of fossil fuels and into clear power.
There was additionally short-lived hope that the COP determination would name on events to “speed up the phasing-out of coal and subsidies for fossil fuels.” In line with the United Nations, eliminating all fossil gas subsidies would cut back international carbon emissions as much as 10 per cent by 2030. Sadly earlier than the pact was agreed, the textual content on coal was watered down, the phrase “phasing out” was changed with “phasing down”, and the weasel phrase “inefficient” was inserted earlier than “subsidies for fossil fuels.”
The truth that not even a weak reference to fossil fuels can survive within the determination textual content speaks volumes about how divorced the COP course of is from the realities of the local weather disaster. And that is unlikely to vary so long as fossil gas lobbyists are permitted to attend.

COP26 leaves too many loopholes for the fossil gas trade. Listed here are 5 of them
Cities and buildings
Now firmly on the agenda in nationwide plans and international deal.
On the very least COP26 has put the constructed surroundings extra firmly on the agenda with a full day dedicated to it – it solely rated half a day at Paris in 2015 and earlier than that had little formal acknowledgement. Given buildings are answerable for 40% of worldwide carbon emissions many argue they need to obtain much more consideration, with the World Inexperienced Constructing Council stating they need to be “elevated to a essential local weather resolution”.
There at the moment are 136 nations which have included buildings as a part of their local weather motion plans (referred to as NDCs), up from 88 on the final main COP. As NDCs are the authorized mechanism COP depends on, that issues.
Native governments are, basically, extra engaged with the constructed surroundings than nationwide governments. That is the place planning and constructing laws are permitted and improvement methods established, which dictate how we construct our homes, places of work and neighborhood amenities. The actual fact cities create over 70% of energy-related emissions reinforces their significance. So anticipate native authorities to take a extra lively function in future.
It’s clear that “embodied carbon” and “Scope 3 emissions” will turn into on a regular basis language for building fairly shortly, so be sure to study what they imply.
Away from the formal agenda, the largest rigidity was the talk between know-how and consumption. A number of trade teams at COP26 had been speaking about decarbonising metal and concrete manufacturing with new, and as but unproven, applied sciences. We do want that, however extra importantly we have to change the best way we design buildings so that they use supplies which might be intrinsically low-carbon, akin to timber, and to devour much less assets basically.
However doubtless, the largest win is the particular reference to power effectivity within the adopted textual content of the Glasgow Local weather Pact. That is the primary time power effectivity has been explicitly referenced within the COP course of, and power effectivity is the important thing motion the place buildings have a disproportionate function in mitigating local weather change.
Article 36 calls on governments to “speed up the event, deployment and dissemination” of actions together with “quickly scaling up” power effectivity measures. Be aware the urgency of the language. There may be now a authorized crucial for all nations to align their constructing laws with a low carbon future.

Huge pledges to spice up electrical autos.
COP26 gave extra consideration than ever to transportation, with combined outcomes because of the mess of worldwide aspirations and nationwide politics. Transport is the biggest emitter of greenhouse gases in lots of nations and, after renewable electrical energy, the second most essential technique for reaching web zero emissions.
Greater than 30 nations and 6 automakers pledged to finish gross sales of inside combustion autos by 2040. The record had some notable no-shows – together with the US, Germany, Japan and China, and the 2 largest automotive firms, Volkswagen and Toyota – however was nonetheless spectacular. The shift to electrical autos was already unequivocal. Electrical autos (EVs) reached 20% of gross sales in Europe and China in latest months, and each are headed for full electrification of latest automobiles by 2035 or so.
The transition to electrical and hydrogen vans is about to comply with an identical path. Fifteen nations agreed to work towards transitioning all new vans and buses to zero emissions by 2040. California already requires 70% of gross sales in most truck classes to be zero emissions by 2035. China is on an identical trajectory. These are non-binding agreements, however they’re made simpler by the roughly 50% drop in battery prices because the Paris accord.
Aviation is harder as a result of electrification is at the moment solely doable for brief flights and smaller planes. The US, UK and others agreed to advertise sustainable aviation fuels. It’s a begin.
Some lament the concentrate on EVs additional locking in car-centric residing. However to cut back greenhouse gases, car electrification (together with hydrogen) is the best and financial method to decarbonize transportation – by far.

A declaration on deforestation, nevertheless it isn’t binding
Nature was a giant theme at COP26, and the significance of Indigenous peoples’ rights and tackling commodity provide chains that drive deforestation had been broadly recognised throughout the convention.
Over 135 nations signed a declaration agreeing to halt and reverse forest loss and land degradation by 2030, though Indonesia subsequently backed away from the dedication, underscoring the significance of binding choices reasonably than voluntary declarations for essential outcomes. Donors pledged US$1.7 billion to assist Indigenous peoples and native communities’ forest stewardship. Twenty-eight of the biggest client and producer nations of beef, soy, cocoa and palm oil mentioned a roadmap figuring out areas of labor to deal with deforestation in commodity provide chains.
Nonetheless, declarations can distract from the negotiated outcomes of the UN course of. For nature, an essential end result included within the remaining Glasgow Local weather Pact is that it “emphasizes the significance of defending, conserving and restoring nature and ecosystems to attain the Paris Settlement temperature aim, together with via forests and different terrestrial and marine ecosystems”.
Such recognition of the function of nature is essential to boost the inclusion of ecosystem restoration in nations’ local weather commitments. But, nature alone can’t ship the 1.5°C aim with out different efforts, together with phasing out coal and fossil gas subsidies, offering ample finance to creating nations, and defending human rights.
