This concept, termed “widespread however differentiated tasks and respective capabilities” – typically with extra phrases appended, however extra typically simply referred to by the primary 4 phrases or its acronym CBDR – was therefore designated a core precept underpinning worldwide local weather efforts.
Since then, CBDR has been each a key safeguard and a large headache. It has guided work on many modern initiatives, from inexperienced financing to voluntary nationwide emissions targets. However in every case, international locations have argued lengthy and exhausting over what precisely constitutes honest software of the precept.
The tensions are solely set to develop, because the world is difficult pressed to throw extra assets into preventing local weather disasters and stemming temperature rise. Growing nations, accusing their richer friends of falling quick on guarantees, are typically chided in flip for freeriding. Geopolitical rifts additional complicate the image.
The year-end COP29 local weather convention in Azerbaijan will as soon as once more put the precept to the take a look at, particularly because the deadline looms for international locations to settle phrases on a large financing bundle for poorer, climate-vulnerable international locations. There will even be skirmishes over who ought to get to extract or use probably the most planet-heating fossil fuels.
International inexperienced efforts depend on prepared cooperation and shared rules to work, since strict worldwide legal guidelines have confirmed exhausting to formulate and even more durable to implement. So observers fear that discord over the CBDR credo may paralyse international locations when pressing local weather motion is most wanted.
“I feel [CBDR] has light away considerably. I don’t assume it’s talked about as a lot because it must be,” stated Binyam Gebreyes, senior researcher at UK think-tank Worldwide Institute for Atmosphere and Improvement.
Cash guidelines
Disagreements over the justice precept have been particularly obvious over who ought to pay and obtain cash for local weather initiatives. Distrust stems from developed nations being two years late on a promise to supply US$100 billion a yr by 2020, on high of the quantum set in 2009 seen as scandalously low by recipients.
This time spherical, international locations must agree at COP29 to a brand new funding bundle – a “New Collective Quantified Purpose” – which some growing nations have stated should exceed US$1 trillion yearly to be adequate.
“That’s basically operationalising CBDR,” stated Meenakshi Raman, head of programmes at Malaysia-based nonprofit Third World Community. “It isn’t charity, not improvement help, however an obligation that stems from historic accountability,” she stated.
The Azerbaijan COP29 presidency has stated the brand new funding aim is high precedence on the year-end convention. To clinch a deal it’s going to possible need to mediate a years-long debate on who pays. Developed international locations have lengthy referred to as on newly industrialised nations to additionally contribute, given their capability to take action and the steep sum of cash wanted.
Who makes up the contributor base for local weather finance is a substantive subject, and “a deeply geopolitical one”, stated Alden Meyer, senior affiliate at UK thinktank E3G. International locations which have been pressed to contribute embody the Gulf states, Singapore and China, Meyer famous at a latest press briefing on COP29.
The demand for extra paying international locations is just not new, and had additionally been a sticking level at 2022’s COP27 in Egypt the place a brand new “loss and injury” fund to assist poor international locations rebuild from local weather disasters was established. In that occasion, international locations agreed to pool cash from “all kinds of sources”, with out specifying who precisely is required to pitch in. Since then, about US$800 million has been dedicated by over 20 international locations.
Blurring traces
The world used to have a a lot clearer concept of who pays up on local weather points.
In 1992, 43 international locations largely in Europe and North America have been grouped into an “Annex I” checklist of industrialised nations, which have better tasks and capabilities in preventing world warming. An “Annex II” subset with out ex-Soviet states was informed explicitly to supply funding. The remainder of the world was merely “non-Annex I”.
These Annex groupings thus got here to outline how CBDR would work, for a time. The lists have largely remained unchanged since then, aside from newcomer nations which have all joined as non-Annex I members. Turkey left Annex II in 2002.
Immediately, the fortunes of a number of non-Annex I international locations have modified dramatically for the higher – assume South Korea or Qatar. Many on the checklist have seen their emissions balloon as their economies develop.
“The world has moved on from 1992 and rising economies, particularly China, Russia, Brazil and India, now account for a big share of world emissions. But they don’t seem to be required to assist the least developed international locations and small island growing states,” stated Dr Timo Leiter, distinguished coverage fellow on the London Faculty of Economics and a daily observer at world local weather negotiations.

However asking international locations to maneuver as much as Annex I or II to imagine better local weather duties might be troublesome, since this possible requires a unanimous vote. No states have voluntarily put themselves up for the transfer.
Nor does everybody agree on the necessity for such motion. To Raman, historic accountability for local weather change takes priority over current capabilities – so the burden ought to nonetheless fall extra on the current group of early industrialisers.
“The wealthy world acquired wealthy, not as a result of they have been smarter, however slightly that the entire system was geared in direction of an inequity that made the wealthy world wealthy by way of an unconstrained fossil gas period,” she stated.
The deadlock is such that every point out of CBDR in choice texts is contested, observers say of closed-door world negotiations, the place developed international locations favor to not point out the precept an excessive amount of, and never have it linked to the Annex I/ II lists. These groupings have all however disappeared in key local weather choices, together with the landmark 2015 Paris Settlement to restrict world warming to underneath 2°C.
Alternatively, rising economies like China and Saudi Arabia are stated to regularly harp on the precept, buoyed by the ethical excessive floor it may well typically deliver, and its potential to assist deflect claims of local weather accountability.
To some, the entire debate is changing into pedantic.
Disagreements over whether or not the time period CBDR must be included in choice texts “do probably not serve the aim” of the precept, stated Gebreyes, who believes the discussions ought to as a substitute revolve round concrete motion on technical help, concessional finance and incentives for growing nations to ditch fossil fuels.
Neither does CBDR assure advantages to all growing international locations, given the intensely political nature of apportioning and deflecting world local weather burdens.
Not solely has the precept lengthened debates, it has at instances “made growing international locations struggle one another”, stated Kuki Soejachmoen, co-founder of the Indonesia Analysis Institute for Decarbonization, who was previously a part of the nation’s local weather negotiations workforce.
However local weather finance is one space the place the growing world has benefitted general from sticking to CBDR, she added.
Mitigation dilemmas
The CBDR precept additionally rings loud in efforts to rein in world warming, particularly in ditching the usage of fossil fuels.
Whereas clear energy from photo voltaic and wind have turn out to be cost-competitive, growing international locations nonetheless discover it exhausting to modify due to the steep upfront investments concerned. Many states endowed with coal, oil and fuel reserves are additionally reluctant to move on export income.
So some from the developed world are hesitant to press too exhausting for speedy modifications within the International South.
Sadiq Khan, London mayor and chair of the C40 intergovernmental local weather group, stated on the New York Local weather Week final month that “we’ve got to be respectful” in telling the International South to ditch oil, fuel and coal.
“They’ll want extra time and extra of a runway to make the transition,” Khan stated, whereas calling for wealthier international locations to maneuver quicker.
Such pace – even perhaps quicker than what Khan referred to as for – is probably going wanted from developed nations to stay to the CBDR precept and nonetheless preserve world warming in test.
For one, critics level to the hypocrisy that over half of recent oil and fuel licences since 2020 have been permitted in 5 International North international locations: Australia, Canada, Norway, US and the UK.
Most nations within the developed caucus are additionally aiming to hit net-zero emissions by 2050, a yr popularised by science experiences specifying it as a local weather security threshold. However the 2050 deadline works provided that your complete world meets it on mixture.
“You possibly can’t have the UK or the EU aiming for net-zero by 2050; that might imply you bust the carbon price range,” Raman stated.
Such tensions have appeared publicly, albeit briefly, in latest summits. At 2022’s COP27 in Egypt, an early draft of the choice textual content referred to as for developed international locations to achieve net-negative emissions by 2030. In response, European Union chief local weather negotiator Frans Timmermans referred to as for members to “keep actual a bit”. The suggestion was eliminated in subsequent drafts.
CBDR arguments have additionally been fielded exterior of its technical ambit of multilateral efforts underneath the United Nations. The EU has been accused of breaching the precept for taxing imports of energy-intensive merchandise resembling metal and cement to match the bloc’s personal carbon worth. Funds are anticipated to begin in 2026.
Growing international locations have made their frustration recognized because the scheme was being developed. Simply final month, former India metal secretary Dr Aruna Sharma referred to as it “an entire violation of CBDR”, since producers from growing nations are compelled to just accept a typical tax price with no flexibilities afforded based mostly on circumstance. The EU’s tax income can also be not returned to producers, she famous.
Gebreyes stated that the EU’s transfer is “fairly worrying” because it undermines multilateralism and primarily reverses the much-needed movement of local weather finance to growing nations.
“If we begin dropping belief within the multilateral course of, then [countries] are going to say, ‘we don’t want the United Nations, we don’t want its Framework Conference on Local weather Change, we are able to do it on our personal’, solely to understand we’ll fail,” he stated.
No fast repair
Granted, it’s not a lot the CBDR precept that’s being thrown out at the moment, because the fastened nation lists used to outline actual capabilities and tasks. The place emissions reductions targets have been prescribed based mostly on Annex groupings within the ‘90s (and largely failed), international locations at the moment individually set their very own ambitions underneath the phrases of the 2015 Paris Settlement. The idea of local weather justice has additionally turn out to be extra ingrained at the moment, because the disproportionate dangers confronted by poorer international locations turn out to be ever extra obvious.
Extra highly effective growing international locations have began to pitch in. China operates a “South-South” cooperation programme targeted on sustainable improvement. South Korea and the United Arab Emirates, each non-Annex I, have just lately pledged cash in direction of the loss and injury fund.
However the blurred and more and more voluntary notions of what CBDR means at the moment nonetheless worries some observers.
Gebreyes believes that “sooner or later” the world wants an replace to the Annex groupings to raised mirror latest improvement patterns – although for now extra urgent points such because the supply of recent local weather funds must take priority.
“I imagine there is a crucial dialog [to be had] on the place the world is with [development] constructions,” he stated. Future updates mustn’t solely mirror prevailing situations, but in addition make it simpler for groupings to maintain abreast with world improvement patterns, he added.
Soejachmoen agrees that extra readability is required. “I don’t have names of nations in thoughts, however I feel the grouping of developed and growing international locations underneath the UN Framework Conference on Local weather Change ought to think about the progress of improvement of every nation, their pathways of emission reductions per capita and per financial output, in addition to their Human Improvement Index,” she stated.
The controversy over who must be receiving local weather finance at the moment, no less than, seems to be crystallising quicker round two teams, of “least developed international locations” and “small island growing states”, each of which have clearly outlined members.
To Leiter on the London Faculty of Economics, maybe the favored notion of what CBDR entails must be revised.
“CBDR has come to be seen as a synonym for solidarity with growing international locations, however the way in which it was operationalised in 1992 by now really limits the solidarity that probably the most susceptible international locations ought to obtain,” he stated, including that many don’t realise the precept helps main emitters keep away from accountability and thus hurts international locations most in want.
Leiter believes a polluter-pays precept, based mostly on historic emissions, would provide a fairer basis. Formalising one other idea may nicely open a brand new can of worms, although some international locations are showing to gravitate in direction of it. COP29 host Azerbaijan has stated it needs to launch a local weather fund voluntarily seeded by contributions from fossil fuel-producing international locations, with a goal of US$1 billion.
However CBDR itself stays non-negotiable, not after the precept continues to stay on within the Paris Settlement, says Raman. Developed international locations pushing towards the precept now constitutes renegotiation, she provides.
“In an effort to handle inequity, the local weather regime has to respect this precept. In any other case the poor might be even poorer,” she stated.
