After negotiations extending beyond the conference’s scheduled conclusion, governments at COP27 in Egypt reached an agreement early today that developing countries have demanded for decades: the creation of a dedicated fund to address loss and damage caused by climate change.
The phrase sounds bureaucratic, but the argument underneath it is relatively straightforward. Climate policy has traditionally concentrated on two categories. The first is mitigation, meaning reducing greenhouse-gas emissions so future warming is smaller. The second is adaptation, meaning preparing societies for climatic changes that can no longer be avoided through measures such as flood defences, drought-resistant agriculture or more resilient infrastructure. Loss and damage concerns what happens after those strategies are insufficient: homes have already disappeared, crops have already failed, coastlines have already been lost or communities have already been displaced.
At COP27, governments agreed to establish new funding arrangements and a dedicated fund for developing countries particularly vulnerable to those losses. A transitional committee will now have to recommend how the fund should actually operate before next year’s climate conference.
That last sentence is the important one.
Governments have agreed on the principle.
They have not solved the political economy.
Who pays? How much? Who qualifies? What counts as climate-related damage? Should money arrive as grants or loans? Should China contribute? Should India? Should financing reflect historical emissions, current emissions, national income or some combination? How should governments distinguish climate damage from losses caused partly by poor domestic planning? How can funding reach vulnerable citizens without disappearing into corrupt or ineffective institutions?
Those questions determine whether today’s agreement becomes a genuine redistribution of climate risk or another impressive announcement followed by inadequate implementation.
This is where climate justice becomes difficult because moral arguments are easier to construct than allocation formulas.
The strongest argument for loss-and-damage finance begins with an externality. Greenhouse gases mix globally in the atmosphere. Emissions produced in Manchester, Mumbai, Houston or Shanghai contribute to climatic changes that do not respect national borders. The person experiencing the eventual damage may have contributed almost nothing to producing it.
Pakistan’s floods this summer made that problem unusually visible. Tens of millions of people were affected by catastrophic flooding in a country whose historical contribution to accumulated global emissions is tiny compared with the industrialised economies that became wealthy through two centuries of fossil-fuel-intensive development.
A Pakistani family losing its home does not receive a lower repair bill because most of the carbon contributing to global warming was emitted elsewhere.
Climate change separates the location of production from the location of damage.
Ordinary political institutions are poorly designed for that problem because governments remain nationally accountable. A British government collects taxes from British citizens and is judged by British voters. Asking those citizens to finance reconstruction thousands of kilometres away requires explaining why the cost belongs partly to them.
The climate-justice argument answers that historical emissions create a degree of responsibility.
That principle has substantial moral force.
Turning it into numbers is considerably harder.
Suppose historical emissions determine responsibility. How far backwards should we calculate? Industrialisation began before modern governments understood the climatic consequences of coal. Should emissions produced in 1850 carry the same moral weight as emissions produced after climate science became clear? Should responsibility belong to the country where carbon was emitted or to consumers elsewhere who purchased the goods produced using that carbon?
Even national boundaries create complications. Britain’s industrial revolution occurred under political institutions and territorial arrangements different from today’s United Kingdom. India’s colonial-era emissions occurred while India was governed by Britain. Should those emissions be assigned territorially to India or politically to the imperial power controlling much of the economy?
The arithmetic contains history.
That makes supposedly technical accounting politically contested.
Current emissions create another problem. China is now the world’s largest annual emitter of carbon dioxide, while India is also a major and growing emitter in absolute terms. Yet their historical per-capita contributions remain far below those of several wealthy industrialised countries, and their per-capita incomes remain much lower.
So which principle should dominate?
Historical responsibility points towards wealthy industrialised states.
Current emissions increase the importance of China and other emerging economies.
Ability to pay points towards rich countries.
Population-adjusted fairness changes the comparison again.
There is no scientifically determined answer because the choice between those metrics is partly ethical.
Climate science can estimate emissions and warming.
It cannot determine how responsibility should be distributed between generations and countries.
Politics has to do that.
This is why climate negotiations move so slowly. Governments are not simply arguing about whether climate change exists. They are bargaining over potentially enormous distributions of wealth and development opportunities.
Every emissions target implies something about who can use the remaining atmospheric carbon budget.
Every financing commitment implies taxpayers somewhere transferring resources elsewhere.
Every adaptation programme implies priorities among competing projects.
Climate diplomacy is therefore economic distribution conducted internationally.
The loss-and-damage fund makes that distribution more explicit than before.
There is another difficult question: what counts as damage caused by climate change?
A cyclone occurs in a warming world. Climate change may have increased its intensity or rainfall, but cyclones existed before industrialisation. A drought destroys crops, but poor irrigation also contributed. A flood destroys thousands of homes, but some were built on floodplains where construction should never have been permitted.
How should responsibility be divided?
Attribution science is becoming increasingly sophisticated and can estimate how climate change alters the probability or severity of particular extreme events. But governments cannot realistically conduct a multi-year scientific attribution study before providing emergency assistance after every disaster.
Funding mechanisms therefore need rules that operate under uncertainty.
This creates a risk in both directions.
Set the evidentiary threshold too high and vulnerable countries struggle to receive money precisely when they need it.
Set it too low and almost every natural disaster becomes eligible for international climate compensation regardless of domestic policy failures.
The solution will probably require recognising shared causation.
Climate change can increase the hazard while domestic governance determines vulnerability.
Neither explanation cancels the other.
This is the argument I made after Pakistan’s floods, and COP27 makes it institutionally important. Wealthy countries should not use poor governance in developing states as an excuse to ignore climate responsibility. Developing-country governments should not use climate responsibility as an excuse to ignore poor land-use planning, infrastructure failures or corruption.
A flood can be intensified by global warming and worsened by domestic policy simultaneously.
Finance should be designed around that reality rather than searching for one exclusive culprit.
The form of finance matters too.
If a poor country experiences a climate disaster and responds by borrowing money, the disaster increases its debt burden. Higher debt servicing then reduces fiscal space available for adaptation, making the country more vulnerable to the next disaster.
The cycle becomes self-reinforcing.
This is why many developing countries argue that loss-and-damage finance should rely heavily on grants rather than loans. A country that contributed little to the underlying climatic problem should not necessarily become more indebted because it happens to be geographically vulnerable to that problem.
That argument is particularly powerful for small island states. Some face rising sea levels that threaten land, freshwater supplies and eventually the viability of communities themselves. Lending them money to cope with a problem largely produced elsewhere can appear economically absurd.
But grants create the political problem on the donor side. Taxpayers in wealthy countries need to accept transfers from which they receive no immediate visible domestic benefit.
This is where the climate argument needs to become more sophisticated than guilt.
There are self-interested reasons for wealthy countries to finance resilience elsewhere. Climate disasters can increase migration pressures, disrupt supply chains, destabilise governments, create humanitarian crises and reduce global economic growth.
Helping vulnerable states adapt is therefore partly insurance against international instability.
Justice and self-interest can point in the same direction.
Policy is often more durable when they do.
There is also a question of whether China should contribute. The traditional structure of climate negotiations divides countries partly according to categories created in the early 1990s, when China was much poorer and contributed a far smaller share of global emissions than it does today.
The world economy has changed dramatically since then.
Any durable climate-finance system will eventually need to recognise that the category “developing country” contains economies with radically different capabilities.
China and Chad are both outside the traditional developed-country category.
Their fiscal capacities are not remotely comparable.
The same applies, to a lesser extent, across the wider emerging world.
A principle created to reflect historical inequality can become increasingly inaccurate if institutional categories never update.
But updating cannot simply mean wealthy Western countries shifting obligations onto emerging economies once those economies become large enough to compete economically.
Historical responsibility does not disappear because China industrialised later.
The eventual financing formula therefore probably needs multiple dimensions: cumulative emissions, contemporary capacity, current emissions and vulnerability.
That will be politically ugly.
It may also be more defensible than a binary division designed thirty years ago.
India occupies an especially interesting position. It is already one of the world’s largest total emitters because of its enormous population, yet its per-capita emissions remain substantially below those of the United States and several other wealthy countries. Hundreds of millions of Indians still have living standards far below those in developed economies.
Demanding that India decarbonise according to exactly the same historical timetable as countries that became wealthy through unrestricted fossil-fuel use would therefore be difficult to justify.
At the same time, India’s future emissions matter enormously for whether global temperature goals remain achievable.
Climate justice cannot therefore mean allowing developing countries simply to repeat the carbon-intensive development path of today’s wealthy states.
There is not enough atmospheric space.
The solution has to involve making cleaner development economically attractive enough that countries do not have to choose between poverty reduction and climate mitigation.
That requires technology, investment and finance.
Again, wealthy-country climate commitments should not be understood only as compensation.
They are part of the infrastructure required for a feasible global transition.
COP27’s outcome is less impressive on mitigation. Governments reaffirmed the objective of limiting warming to 1.5°C, but the conference did not produce the dramatic increase in emissions-cutting ambition that climate scientists and many governments wanted. UN Secretary-General António Guterres concluded that the world still required a major increase in climate ambition.
That creates a slightly uncomfortable possibility: international climate politics may become better at discussing how to compensate for climate damage while remaining inadequate at preventing the damage from increasing.
Loss-and-damage finance is necessary.
It is not a substitute for mitigation.
If global emissions remain high, the scale of future loss becomes too large for any realistic fund to compensate.
This is an important economic point. Insurance cannot solve a risk whose probability and severity continue increasing indefinitely.
Eventually the premium becomes unaffordable.
Climate finance therefore needs three connected pillars rather than competing priorities: reduce future warming, adapt to unavoidable warming, and compensate for losses that neither strategy prevents.
Mitigation reduces the size of the future liability.
Adaptation reduces exposure.
Loss-and-damage finance distributes the residual cost.
Treating them as alternatives misunderstands the system.
The politics nevertheless encourages competition between them because financial resources are finite. Every billion dollars spent on reconstruction is a billion not spent somewhere else unless governments increase total climate finance.
Developing countries therefore reasonably worry that a new loss-and-damage fund could simply relabel existing development assistance rather than provide genuinely additional resources.
That would weaken today’s achievement substantially.
If a government moves £1 billion from an adaptation programme into a newly branded loss-and-damage fund, the headline changes while total support does not.
Accounting therefore becomes political again.
“New and additional” finance sounds like administrative language.
It determines whether vulnerable countries actually receive more resources.
The fund will also need strong governance. Climate justice does not require writing blank cheques to governments simply because their citizens are vulnerable.
Corruption hurts the intended beneficiaries most.
If international financing disappears through patronage networks, wealthy-country taxpayers become more sceptical of future contributions and vulnerable communities remain unprotected.
Accountability therefore strengthens rather than undermines climate justice.
The challenge is designing accountability without recreating paternalistic relationships in which donor governments effectively control recipient-country policy.
Developing countries have long criticised international financial institutions for conditionality that can constrain domestic political choices.
Loss-and-damage finance could reproduce similar tensions if wealthy donors attach extensive policy conditions to every transfer.
There needs to be enough oversight to ensure money reaches its intended purpose without converting climate finance into another instrument of political control.
That balance will be difficult.
The institutional structure of the fund may therefore matter almost as much as its eventual size.
Who gets voting power?
Donors?
Recipients?
Multilateral institutions?
How are projects selected?
Can communities apply directly?
How quickly can money be released after disasters?
Does funding prioritise the poorest countries or the largest absolute damages?
Every design choice creates winners and losers.
This is what happens when moral principles become institutions.
Ambiguity disappears.
Somebody has to write the formula.
Perhaps that is why today’s agreement should be celebrated cautiously.
For decades, vulnerable countries argued that the international climate system focused heavily on emissions reduction while failing to acknowledge that some climate harms were already unavoidable and disproportionately imposed on countries with little responsibility for causing them.
COP27 has finally accepted the principle that dedicated funding should address those losses.
That is significant.
But institutions should be judged by transfers, not declarations.
How much money enters the fund?
Who contributes?
How quickly does it reach communities after disasters?
Does it supplement rather than replace existing climate finance?
Does it reduce the debt burden created by reconstruction?
Those numbers will determine whether Sharm el-Sheikh becomes a turning point or another conference remembered mainly for the wording of its final declaration.
There is also a broader international-relations consequence. Climate change is shifting bargaining power towards the Global South because wealthy states cannot construct a credible climate regime without developing-country participation.
India, Pakistan, African states, small island countries and other developing economies are not merely recipients of Western climate policy.
They are negotiating actors.
The G77 and China pushed loss and damage onto the political agenda because their collective participation matters to the legitimacy of the entire climate process.
This is the same multipolar dynamic I discussed after the G7 summit in June.
Power is becoming more dispersed, and international institutions increasingly have to accommodate demands from countries that previously possessed less agenda-setting capacity.
That does not eliminate inequality in international politics.
The United States and European Union still possess vastly greater financial resources than vulnerable developing states.
But vulnerable countries can exercise coalitional power.
Individually, a small island state has little economic leverage over Washington.
Collectively, developing countries can make an international climate agreement politically impossible to present as legitimate without addressing their concerns.
Institutions therefore create forms of power that do not map directly onto GDP.
COP27’s loss-and-damage agreement is partly the result.
The irony is that the fund becomes necessary because another form of international cooperation has been insufficient. Governments have known about climate change for decades and still have not reduced emissions fast enough to prevent increasingly serious damage.
Today’s agreement is therefore both progress and evidence of failure.
Humanity has accepted that some losses can no longer be avoided.
That should produce solidarity.
It should also produce urgency.
A world that becomes excellent at compensating climate disasters while continuing to make them more severe would not constitute successful climate governance.
The best loss-and-damage fund is one that eventually needs to spend less than feared because mitigation and adaptation worked.
We are nowhere near that world yet.
For Pakistan, small island states and other vulnerable countries, the argument is no longer hypothetical. Homes, infrastructure and livelihoods are already being lost.
The question has moved from whether wealthy countries possess some responsibility to what that responsibility costs.
That is where political principles become serious.
It is easy to say climate change is a global problem.
It is harder to decide who receives the invoice.
COP27 has finally agreed that the invoice cannot simply remain with whoever happened to be standing where the climate disaster landed.
Now governments have to decide how to divide it.
