Over two weeks in November, world leaders and nationwide negotiators will meet in Scotland to debate what to do about local weather change. It’s a posh course of that may be laborious to make sense of from the surface, nevertheless it’s how worldwide legislation and establishments assist remedy issues that no single nation can repair by itself.
I labored for the United Nations for a number of years as a legislation and coverage adviser and have been concerned in worldwide negotiations. Right here’s what’s occurring behind closed doorways and why individuals are involved that COP26 may not meet its objectives.
In 1992, international locations agreed to a global treaty referred to as the United Nations Framework Conference on Local weather Change (UNFCCC), which set floor guidelines and expectations for international cooperation on combating local weather change. It was the primary time nearly all of nations formally acknowledged the necessity to management greenhouse gasoline emissions, which trigger international warming that drives local weather change.
That treaty has since been up to date, together with in 2015 when nations signed the Paris local weather settlement. That settlement set the objective of limiting international warming to “nicely under” 2 levels Celsius (3.6 F), and ideally to 1.5 C (2.7 F), to keep away from catastrophic local weather change.
COP26 stands for the twenty sixth Convention of Events to the UNFCCC. The “events” are the 196 international locations that ratified the treaty plus the European Union. The UK, partnering with Italy, is internet hosting COP26 in Glasgow, Scotland, from Oct. 31 by way of Nov. 12, 2021, after a one-year postponement as a result of COVID-19 pandemic.
Why are world leaders so targeted on local weather change?
The U.N. Intergovernmental Panel on Local weather Change’s newest report, launched in August 2021, warns in its strongest phrases but that human actions have unequivocally warmed the planet, and that local weather change is now widespread, fast and intensifying.
The IPCC’s scientists clarify how local weather change has been fueling excessive climate occasions and flooding, extreme warmth waves and droughts, loss and extinction of species, and the melting of ice sheets and rising of sea ranges. U.N. Secretary-Basic António Guterres referred to as the report a “code pink for humanity.”
Sufficient greenhouse gasoline emissions are already within the ambiance, and so they keep there lengthy sufficient, that even below probably the most formidable state of affairs of nations rapidly decreasing their emissions, the world will expertise rising temperatures by way of no less than mid-century.
Nonetheless, there stays a slim window of alternative. If international locations can reduce international emissions to “web zero” by 2050, that would deliver warming again to below 1.5 C within the second half of the twenty first century. The way to get nearer to that course is what leaders and negotiators are discussing.
What occurs at COP26?
Throughout the first days of the convention, round 120 heads of state, like U.S. President Joe Biden, and their representatives will collect to display their political dedication to slowing local weather change.
As soon as the heads of state depart, nation delegations, usually led by ministers of atmosphere, have interaction in days of negotiations, occasions and exchanges to undertake their positions, make new pledges and be part of new initiatives. These interactions are based mostly on months of prior discussions, coverage papers and proposals ready by teams of states, U.N. workers and different consultants.
Nongovernmental organizations and enterprise leaders additionally attend the convention, and COP26 has a public aspect with classes targeted on subjects such because the impression of local weather change on small island states, forests or agriculture, in addition to exhibitions and different occasions.
The assembly ends with an consequence textual content that each one international locations conform to. Guterres publicly expressed disappointment with the COP25 consequence, and there are indicators of bother heading into COP26.
What’s COP26 anticipated to perform?
Nations are required below the Paris Settlement to replace their nationwide local weather motion plans each 5 years, together with at COP26. This yr, they’re anticipated to have formidable targets by way of 2030. These are often called nationally decided contributions, or NDCs.
The Paris Settlement requires international locations to report their NDCs, nevertheless it permits them leeway in figuring out how they scale back their greenhouse gasoline emissions. The preliminary set of emission discount targets in 2015 was far too weak to restrict international warming to 1.5 levels Celsius.
One key objective of COP26 is to ratchet up these targets to achieve web zero carbon emissions by the center of the century.
One other goal of COP26 is to extend local weather finance to assist poorer international locations transition to wash vitality and adapt to local weather change. This is a vital challenge of justice for a lot of growing international locations whose individuals bear the most important burden from local weather change however have contributed least to it. Rich international locations promised in 2009 to contribute $100 billion a yr by 2020 to assist growing nations, a objective that has not been reached. The U.S., U.Okay. and EU, among the many largest historic greenhouse emitters, are rising their monetary commitments, and banks, companies, insurers and personal traders are being requested to do extra.
Different targets embody phasing out coal use and producing options that protect, restore or regenerate pure carbon sinks, comparable to forests.
One other problem that has derailed previous COPs is agreeing on implementing a carbon buying and selling system outlined within the Paris Settlement.

Are international locations on monitor to satisfy the worldwide local weather objectives?
The U.N. warned in September 2021 that international locations’ revised targets have been too weak and would go away the world on tempo to heat 2.7 C (4.9 F) by the top of the century. Nonetheless, governments are additionally going through one other problem this fall that would have an effect on how they reply: Power provide shortages have left Europe and China with value spikes for pure gasoline, coal and oil.
China – the world’s largest emitter – has not but submitted its NDC. Main fossil gasoline producers comparable to Saudi Arabia, Russia and Australia appear unwilling to strengthen their commitments. India – a important participant because the second-largest shopper, producer and importer of coal globally – has additionally not but dedicated.
Different growing nations comparable to Indonesia, Malaysia, South Africa and Mexico are essential. So is Brazil, which, below Javier Bolsonaro’s watch, has elevated deforestation of the Amazon – the world’s largest rainforest and essential for biodiversity and eradicating carbon dioxide from the ambiance.
What occurs if COP26 doesn’t meet its objectives?
Many insiders consider that COP26 received’t attain its objective of getting sturdy sufficient commitments from international locations to chop international greenhouse gasoline emissions 45% by 2030. Meaning the world received’t be on a easy course for reaching net-zero emissions by 2050 and the objective of protecting warming below 1.5 C.
However organizers keep that protecting warming below 1.5 C remains to be potential. Former Secretary of State John Kerry, who has been main the U.S. negotiations, stays hopeful that sufficient international locations will create momentum for others to strengthen their discount targets by 2025.

The price of failure is astronomical. Research have proven that the distinction between 1.5 and a couple of levels Celsius can imply the submersion of small island states, the loss of life of coral reefs, excessive warmth waves, flooding and wildfires, and pervasive crop failure.
That interprets into many untimely deaths, extra mass migration, main financial losses, giant swaths of unlivable land and violent battle over sources and meals – what the U.N. secretary-general has referred to as “a hellish future.”
