Do you know your GFANZ from your ISSB from your PPCA? Welcome to COP26!
With truly global initiatives to slash the rate of planetary warming hard to come by, governments, companies and civil society groups are banding together in multiple smaller groups to try and accelerate change.
Keeping track of the cornucopia of new clubs and alliances - each with its own, though sometimes overlapping, aims, is a headache both for outsiders and those inside the UN climate conference in Scotland.
Governments have announced each alliance to great fanfare, but behind the scenes, they too are scrambling to keep up.
One official, speaking on condition of anonymity, described updating an announcement repeatedly overnight as more countries were persuaded to join one of the pledges.
Some environmental groups worried important substance was being dropped in such last-minute scrambles, with agreements sounding better than they may turn out to be in practice.
"Assessing their true worth is hugely difficult, especially at speed during a COP meeting," Mohamed Adow, director of climate justice NGO Power Shift Africa, said in a tweet on Thursday, describing the new groupings as "eye candy".
Others saw the barrage of new partnerships and initatives as evidence of greater engagement in an issue sorely neglected for decades. "We've never had as much corporate presence or commitment," US climate envoy John Kerry said.
Group of groups
There's the Glasgow Financial Alliance for Net Zero (GFANZ) - an umbrella group of clubs for insurers, banks, asset managers and other sub-sectors of the finance industry.
They say they represent more than $130 trillion in assets, and will be under pressure to meet the need for an estimated $100 trillion in climate finance over the next three decades.
UN climate envoy Mark Carney chairs that alliance and has also launched another - the Taskforce on Scaling up Voluntary Carbon Markets (TSVCM) to boost private-sector investment in voluntary carbon offset credits.
The International Sustainability Standards Board (ISSB), backed by financial market regulators, was also announced on Wednesday and aims to standardise how companies should report on their climate risk exposure and sustainability practices.
On Tuesday, some companies and governments pledged to use their spending power to fuel research and development of climate technologies under a US-led 'First Movers Coalition' (FMC).
Confused yet? Those groups are just about the money.
On Thursday, themed "Energy Day" at COP26, non-profit groups said they were busy just "untangling" announcements, such as Britain's 'Global Coal to Clean Power Transition Statement' representing various other energy pledges - some old, some new.
Another new group of 20 countries and five development institutions promised to stop financing fossil fuels overseas; it has yet to give itself a name.
Pauline Heinrichs, Policy Advisor at climate thinktank E3G, said the announcements may have taken some unpicking, but really did represent a tipping point in efforts to consign coal to history.
"Seeing major coal-burning economies such as Vietnam, Indonesia, South Korea and Ukraine commit to a coal exit genuinely is the progress we need to see," she said.
There's also the 'Beyond Oil and Gas Alliance' (BOGA), under which countries will commit next week to ending new oil and gas permits and to winding down production.
The Asian Development Bank's pilot Energy Transition Mechanism (ETM), meanwhile, aims to accelerate the retirement of coal in southeast Asia by buying off and retiring coal assets.
Some observers said financial institutions had made unprecedented commitments to align portfolios, products, and services with the Paris Agreement but they were as yet untested.
"We now need to focus resolutely on the quality of promises made by financial institutions, not just their quantity," Ben Caldecott, director of the Oxford Sustainable Finance Group at the University of Oxford, said.
