We requested specialists from around the globe for his or her response to the outcomes of this yr’s UN local weather summit, COP26, together with the Glasgow Local weather Pact agreed by all 197 international locations attending the talks. Right here’s what they needed to say concerning the offers that had been made. (This web page might be up to date as reactions are available in.)
Offers and targets
A place to begin for future motion.
The Glasgow Local weather Pact is just not excellent, however nonetheless strengthens the Paris settlement in a number of methods. Acknowledging that there isn’t a secure restrict for world warming, the Pact resolves to restrict world warming to 1.5°C, as a substitute of the Paris textual content of “effectively under 2°C”. Crucially it additionally delivers a powerful framework for monitoring commitments in opposition to real-world progress.
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 international locations would supply a minimum of US$100 billion a yr of economic help to assist growing international locations adapt to mounting storms and droughts – a pledge that also has not been met – and the transition to wash power was supposed to begin 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 sequence 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 sequence of bulletins by states, cities and companies on a variety 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. The pact now explicitly “requests events to revisit and strengthen” their 2030 targets, which means 1.5°C is down however not out.

Greenhouse fuel emissions
Progress on slicing 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 due to this fact president of COP26 wished 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 world warming to 1.5°C is on life help – it has a pulse nevertheless it’s practically lifeless.
Earlier than COP26, the world was on monitor for two.7°C of warming, based mostly on commitments by international locations, and expectation of the modifications in expertise. Bulletins at COP26, together with new pledges to chop emissions this decade, by some key international locations, have decreased this to a finest estimate of two.4°C.
Extra international locations additionally introduced long-term web zero targets. One of the vital necessary was India’s pledge to achieve web zero emissions by 2070. Critically, the nation stated it will 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 whole utilization, decreasing its emissions in 2030 by 1 billion tonnes (from a present whole of round 2.5 billion).
A world warming by 2.4°C remains to be clearly very removed from 1.5°C. What stays is a near-term emissions hole, as world emissions look more likely to flatline this decade somewhat than exhibiting 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 it is advisable to know concerning the Glasgow Local weather Pact
Fossil gasoline finance
Some progress on ending subsidies, however the closing deal fell brief.
An important outcomes from COP26 might be immediately associated to 2 “F-words”: finance and fossil fuels. Shut consideration must be paid to pledges for brand spanking new finance for mitigation, adaptation, and loss and injury. However we should keep in mind the opposite facet of the equation — the pressing want to chop off funding for fossil gasoline initiatives. Because the Worldwide Vitality Company made clear earlier this yr, there isn’t a room within the 1.5℃ carbon funds for any new investments in fossil fuels.
The dedication from greater than 25 international locations to close off new worldwide finance for fossil gasoline initiatives by the top of 2022 is without doubt one of the largest 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 choice would name on events to “speed up the phasing-out of coal and subsidies for fossil fuels.” In response to the United Nations, eliminating all fossil gasoline subsidies would scale back world carbon emissions as much as 10% 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 choice 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 gasoline lobbyists are permitted to attend.

COP26 leaves too many loopholes for the fossil gasoline trade. Listed below are 5 of them
A declaration on deforestation, nevertheless it isn’t binding.
Nature was an enormous 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 international locations 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 selections somewhat than voluntary declarations for necessary outcomes. Donors pledged US$1.7 billion to help Indigenous peoples and native communities’ forest stewardship. Twenty-eight of the biggest client and producer international locations of beef, soy, cocoa and palm oil mentioned a roadmap figuring out areas of labor to deal with deforestation in commodity provide chains.
Nevertheless, declarations can distract from the negotiated outcomes of the UN course of. For nature, an necessary final result included within the closing 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 position of nature is crucial to boost the inclusion of ecosystem restoration in international locations’ local weather commitments. But, nature alone can not ship the 1.5°C aim with out different efforts, together with phasing out coal and fossil gasoline subsidies, offering enough finance to growing international locations, and defending human rights.

Forests cannot deal with all of the net-zero emissions plans – corporations and international locations count on nature to offset an excessive amount of carbon
Massive pledges to spice up electrical automobiles.
COP26 gave extra consideration than ever to transportation, with blended outcomes because of the mess of worldwide aspirations and nationwide politics. Transport is the biggest emitter of greenhouse gases in lots of international locations and, after renewable electrical energy, the second most necessary technique for reaching web zero emissions.
Greater than 30 international locations and 6 automakers pledged to finish gross sales of inner combustion automobiles by 2040. The listing had some notable no-shows – together with the US, Germany, Japan and China, and the 2 largest automotive corporations, Volkswagen and Toyota – however was nonetheless spectacular. The shift to electrical automobiles was already unequivocal. Electrical automobiles (EVs) reached 20% of gross sales in Europe and China in latest months, and each are headed for full electrification of latest vehicles by 2035 or so.
The transition to electrical and hydrogen vehicles is about to observe the same path. Fifteen international locations agreed to work towards transitioning all new vehicles 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 the same 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 attainable for brief flights and smaller planes. The US, UK and others agreed to advertise sustainable aviation fuels. It’s a begin.
Some lament the deal with EVs additional locking in car-centric residing. However to cut back greenhouse gases, car electrification (together with hydrogen) is the simplest and financial method to decarbonize transportation – by far.

COP26: Seven causes world transport is so exhausting to decarbonise
Cities and buildings
Now firmly on the agenda in nationwide plans and world 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 accountable 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 crucial local weather answer”.
There are actually 136 international locations which have included buildings as a part of their local weather motion plans (generally known 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 growth methods established, which dictate how we construct our homes, workplaces and neighborhood amenities. The very fact cities create over 70% of energy-related emissions reinforces their significance. So count on native authorities to take a extra energetic position in future.
It’s clear that “embodied carbon” and “Scope 3 emissions” will turn into on a regular basis language for building fairly rapidly, so ensure you be taught what they imply.
Away from the formal agenda, the most important stress was the controversy between expertise and consumption. Plenty 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 way in which we design buildings so that they use supplies which can be intrinsically low-carbon, comparable to timber, and to eat much less assets basically.
However no doubt, the most important win is the precise 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 position 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 international locations to align their constructing laws with a low carbon future.

Discussions relied on unproven applied sciences.
COP26 featured a whole bunch of commitments to energy previous coal and pure fuel and provide simply transitions to staff and communities, principally with a deal with renewable power transitions.
Nevertheless, one concern I’ve popping out of COP26 is that discussions are sometimes selling applied sciences that aren’t at the moment market prepared or scalable, particularly nuclear small modular reactors, hydrogen and carbon seize and storage.
In response to the Worldwide Vitality Company, 38 applied sciences are prepared for deployment proper now, together with photo voltaic photovoltaic, geothermal and wind energy. But none has been deployed on the scale we have to obtain 1.5℃. Renewable power, at the moment 13% of the worldwide power system, wants to achieve 80% or extra.
Globally, a transition to renewable power will price between US$22.5 trillion and US$139 trillion. What’s wanted are insurance policies that help a mixture of improvements, speed up the scale-up of renewable power and modernize energy grids — together with the appropriate for customers and residents to generate energy to promote to their neighbours and the grid. Additionally they have to help enterprise fashions that provide income to communities and jobs for these in industries in transition.

Science and innovation
Low-carbon metal, concrete and subsequent era biofuels obtained a lift.
Science and Innovation Day at COP26 noticed fascinating new schemes introduced, and three had been notably necessary.
First, the UK, Germany, Canada, India and the United Arab Emirates fashioned an initiative for growing low carbon metal and concrete, to decarbonise building. Their acknowledged aim is net-zero metal and concrete for public initiatives by 2050, with an earlier 2030 goal but to be introduced. That’s an thrilling undertaking, as building supplies like these contribute about 10% of greenhouse fuel emissions.
Second, a aim of making low-carbon well being care programs was additionally introduced, with 47 international locations becoming a member of that initiative. Whereas the aim of web zero healthcare by 2050 is welcome, it’s hardly a further dedication. If a nation achieves web zero, its well being system may have met that criterion anyway.
Third, Mission Innovation is a collaboration between governments geared toward accelerating applied sciences that may cut back emissions. The Netherlands and India are main a welcome bio-refinery program, aiming to make bio-based various fuels and chemical substances economically enticing.
Much less helpful is the “carbon dioxide removing” undertaking, led by Saudi Arabia, US and Canada. Its aim is a web annual discount of 100 million tonnes of CO₂ by 2030. As world emissions are actually 35 billion tonnes a yr, this undertaking goals to extend fossil gasoline use by capturing solely a token, tiny fraction.
