We requested consultants from all over the world 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 nations attending the talks. Right here’s what they needed to say in regards to the offers that have been made. (This web page will probably be up to date as reactions are available.)
Offers and targets
A place to begin for future motion.
The Glasgow Local weather Pact shouldn’t be good, however nonetheless strengthens the Paris settlement in a number of methods. Acknowledging that there is no such thing as 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 “properly beneath 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 likelihood to “maintain 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 offer at the very least US$100 billion a yr of economic assist to assist growing nations adapt to mounting storms and droughts – a pledge that also has not been met – and the transition to wash power was supposed to start out being rolled out.
Maybe involved that nationwide targets collectively have been nowhere close to ok to maintain 1.5°C alive – we have been heading for extra like 2.4°C at greatest – 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 have 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 throughout the subsequent yr. The pact now explicitly “requests events to revisit and strengthen” their 2030 objectives, that means 1.5°C is down however not out.

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 “maintain 1.5°C alive”, the stronger objective of the Paris Settlement. However at greatest we are able to say the objective of limiting world warming to 1.5°C is on life help – it has a pulse however it’s almost useless.
Earlier than COP26, the world was on monitor for two.7°C of warming, primarily based 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 diminished this to a greatest estimate of two.4°C.
Extra nations additionally introduced long-term internet zero objectives. One of the essential was India’s pledge to achieve internet zero emissions by 2070. Critically, the nation mentioned it could 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 world emissions look prone to flatline this decade somewhat than displaying the sharp cuts essential to be on the 1.5°C trajectory the pact requires. There’s a gulf between long-term internet zero objectives and plans to ship emissions cuts this decade.

5 issues you could know in regards to the Glasgow Local weather Pact
Fossil gasoline finance
Some progress on ending subsidies, however the closing deal fell brief.
A very powerful outcomes from COP26 will probably be immediately associated to 2 “F-words”: finance and fossil fuels. Shut consideration needs to be paid to pledges for brand spanking new finance for mitigation, adaptation, and loss and harm. However we should keep in mind the opposite aspect of the equation — the pressing want to chop off funding for fossil gasoline tasks. Because the Worldwide Vitality Company made clear earlier this yr, there is no such thing as a 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 gasoline tasks by the tip of 2022 is among the greatest successes to return 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 resolution would name on events to “speed up the phasing-out of coal and subsidies for fossil fuels.” Based on the United Nations, eliminating all fossil gasoline subsidies would cut 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 resolution 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, however 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 have 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 somewhat than voluntary declarations for essential outcomes. Donors pledged US$1.7 billion to help Indigenous peoples and native communities’ forest stewardship. Twenty-eight of the most important shopper and producer nations of beef, soy, cocoa and palm oil mentioned a roadmap figuring out areas of labor to sort out deforestation in commodity provide chains.
Nevertheless, declarations can distract from the negotiated outcomes of the UN course of. For nature, an essential end 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 objective, together with via forests and different terrestrial and marine ecosystems”.
Such recognition of the function of nature is crucial to reinforce the inclusion of ecosystem restoration in nations’ local weather commitments. But, nature alone can’t ship the 1.5°C objective with out different efforts, together with phasing out coal and fossil gasoline subsidies, offering satisfactory finance to growing nations, and defending human rights.

Forests cannot deal with all of the net-zero emissions plans – firms and nations count on nature to offset an excessive amount of carbon
Large 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 most important emitter of greenhouse gases in lots of nations and, after renewable electrical energy, the second most essential technique for reaching internet 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 the same 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 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 present solely potential 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 scale back greenhouse gases, automobile electrification (together with hydrogen) is the simplest and financial method to decarbonize transportation – by far.

COP26: Seven causes world transport is so onerous 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 setting 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 resolution”.
There are actually 136 nations which have included buildings as a part of their local weather motion plans (often called NDCs), up from 88 on the final main COP. As NDCs are the authorized mechanism COP depends on, that issues.
Native governments are, typically, extra engaged with the constructed setting than nationwide governments. That is the place planning and constructing rules are accredited and improvement methods established, which dictate how we construct our homes, workplaces and group services. The very fact cities create over 70% of energy-related emissions reinforces their significance. So count on native authorities to take a extra energetic function in future.
It’s clear that “embodied carbon” and “Scope 3 emissions” will turn out to be 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 controversy between know-how and consumption. A lot of trade teams at COP26 have 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 in order that they use supplies which might be intrinsically low-carbon, akin to timber, and to eat much less sources typically.
However no doubt, the largest 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 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. Notice the urgency of the language. There’s now a authorized crucial for all nations to align their constructing rules with a low carbon future.

Discussions relied on unproven applied sciences.
COP26 featured a whole bunch of commitments to energy previous coal and pure gasoline and provide simply transitions to staff and communities, largely with a concentrate on renewable power transitions.
Nevertheless, one concern I’ve popping out of COP26 is that discussions are sometimes selling applied sciences that aren’t at present market prepared or scalable, particularly nuclear small modular reactors, hydrogen and carbon seize and storage.
Based on 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 present 13% of the worldwide power system, wants to achieve 80% or extra.
Globally, a transition to renewable power will value 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 suitable for customers and residents to generate energy to promote to their neighbours and the grid. Additionally they have to help enterprise fashions that supply income to communities and jobs for these in industries in transition.

Science and innovation
Low-carbon metal, concrete and subsequent technology biofuels obtained a lift.
Science and Innovation Day at COP26 noticed attention-grabbing new schemes introduced, and three have been significantly essential.
First, the UK, Germany, Canada, India and the United Arab Emirates shaped an initiative for growing low carbon metal and concrete, to decarbonise building. Their said objective is net-zero metal and concrete for public tasks 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 gasoline emissions.
Second, a objective of making low-carbon well being care programs was additionally introduced, with 47 nations becoming a member of that initiative. Whereas the objective of internet zero healthcare by 2050 is welcome, it’s hardly a further dedication. If a nation achieves internet zero, its well being system may have met that criterion anyway.
Third, Mission Innovation is a collaboration between governments aimed 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 different fuels and chemical compounds economically enticing.
Much less helpful is the “carbon dioxide elimination” undertaking, led by Saudi Arabia, US and Canada. Its objective is a internet annual discount of 100 million tonnes of CO₂ by 2030. As world emissions are actually 35 billion tonnes a yr, this undertaking goals to delay fossil gasoline use by capturing solely a token, tiny fraction.
