Climate Pledges Are Improving. The Development Model Behind Them Is Not

The latest round of national climate pledges contains a modestly encouraging signal: the projected emissions curve is beginning to bend downwards. It also exposes a more difficult problem. Governments are promising cleaner economies without consistently financing the electricity grids, industrial upgrades, climate resilience and affordable capital needed to build them.

This is why the global climate settlement remains misaligned even when individual targets appear more ambitious. Emissions cuts are being negotiated internationally, energy security is managed nationally, private investors demand commercially viable returns, and communities experience climate change through food prices, unreliable electricity, flooding, heat and lost livelihoods. Each part of the system operates according to a different timetable and set of incentives.

The result is not simply an ambition gap. It is an execution model that asks poorer countries to expand energy access, industrialise, adapt to physical climate damage and reduce emissions simultaneously, often while paying substantially more for capital than wealthier economies. Rich countries, meanwhile, continue to measure progress largely through territorial emissions and finance commitments that say little about whether recipient countries can build functioning low-carbon economies.

According to the latest UN assessment, the national climate plans submitted by 113 parties would reduce global greenhouse-gas emissions in 2035 by approximately 12 percent from 2019 levels. That is progress, but it remains far from a pathway compatible with the Paris Agreement’s most ambitious temperature objective.

The UN Environment Programme estimates that full implementation of current national pledges would still place the world on course for approximately 2.3°C to 2.5°C of warming this century. Existing policies, rather than promises, point towards roughly 2.8°C.

The distinction between pledges and policies is where much of the climate debate now belongs.

A target is not an investment programme

Nationally Determined Contributions, or NDCs, are the central mechanism through which countries state what they intend to do under the Paris Agreement. They are politically important, but they are not necessarily detailed delivery plans.

A government can announce a 2035 emissions target without having resolved how new electricity generation will connect to the grid, who will finance industrial retrofits, how households will afford cleaner heating or transport, or what will replace the tax revenue and employment associated with fossil fuels.

This creates a recurrent problem. Climate targets are judged according to their numerical ambition, while implementation depends on institutions, planning rules, supply chains, engineering capacity, public consent and finance. A pledge may look credible in an international submission but prove difficult to execute through the country’s existing budget, energy system and administrative capacity.

The European Union illustrates both sides of the problem. It has binding legislation, carbon pricing, renewable-energy rules and a large internal market capable of supporting investment. Yet even Europe is struggling with slow permitting, grid congestion, industrial competitiveness and the political distribution of transition costs.

For emerging economies, the constraints are more severe. India must decarbonise a rapidly expanding power system while meeting rising demand from households, industry, transport and digital infrastructure. Brazil combines an unusually clean electricity mix with emissions pressures from land use, agriculture and deforestation. South Africa must reduce its dependence on coal while managing electricity shortages, municipal weakness and employment in mining regions.

These are not diluted versions of the same European transition. They are different development problems.

A credible climate framework therefore cannot judge countries only by how quickly they promise to reduce emissions. It must also examine whether those promises are compatible with energy access, fiscal capacity, employment, industrial development and resilience to climate damage.

Clean-energy capital is growing, but not where it is needed most

Global energy investment reached an estimated $3.3 trillion in 2025, with spending on clean technologies substantially exceeding investment in fossil-fuel supply. On the surface, this suggests that capital is moving in the right direction.

The geographical distribution tells a less reassuring story. Much of the clean-energy investment is concentrated in China, advanced economies and a relatively small group of established emerging markets. Countries with the fastest-growing populations, greatest energy deficits and highest climate vulnerability frequently receive the least affordable capital.

The International Energy Agency estimates that annual clean-energy investment across emerging and developing economies outside China must rise from approximately $270 billion to around $870 billion by the early 2030s merely to meet existing national energy and climate commitments. A pathway consistent with limiting warming to 1.5°C would require approximately $1.6 trillion a year.

The shortage cannot be explained by a lack of renewable resources or project demand. Many African, Asian and Latin American countries have excellent solar, wind, hydroelectric or geothermal potential. The problem is the cost and structure of finance.

A solar project that is commercially attractive at a 5 percent cost of capital may become unviable at 12 or 15 percent. Currency risk, political uncertainty, weak utilities, limited transmission infrastructure and expensive local borrowing can raise the cost of otherwise mature technologies. Investors may prefer another solar project in a wealthy market, where returns are lower but contracts, grids and currencies are more predictable.

Climate policy often assumes that falling technology costs will solve this problem. They help, but cheap solar panels do not compensate for an insolvent electricity buyer, an unavailable grid connection or debt denominated in a foreign currency.

This is the first major misalignment: the countries expected to add the most infrastructure frequently face the highest financing costs.

Climate finance is rising, but adaptation remains secondary

Developed countries provided and mobilised $136.7 billion in climate finance for developing countries in 2024, according to the OECD. This exceeded the longstanding $100 billion annual commitment for the third consecutive year, although the target was originally supposed to have been met in 2020.

Reaching the target late is better than not reaching it. Yet the headline total conceals several weaknesses.

Adaptation accounted for only about one quarter of the finance in both 2023 and 2024, down from approximately one third in 2020. Most of the public climate finance was also provided through loans rather than grants.

Loans can be appropriate for revenue-generating infrastructure such as renewable electricity, efficient transport or industrial equipment. They are far less suitable for many adaptation projects. A sea wall, heat-health programme, drought-monitoring system or flood-resistant local road may prevent enormous losses without producing a direct commercial revenue stream.

Poor and climate-vulnerable countries can therefore be placed in the perverse position of borrowing to protect themselves from damage to which they contributed relatively little. Where public debt is already high, governments must choose between resilience, healthcare, education and other essential expenditure.

This is the second misalignment: finance is structured most readily around projects that can repay investors, while some of the most socially valuable climate investments do not generate cash flows.

The imbalance also distorts what gets built. Solar farms with predictable electricity contracts attract more attention than drainage systems, agricultural extension services or urban heat planning. Mitigation remains essential, but a financing architecture that systematically favours bankable emissions projects over resilience will leave vulnerable communities exposed to damage that is already unavoidable.

Energy transition plans frequently ignore the grid

Political announcements tend to focus on generating technologies: more wind, more solar, more nuclear power or a phase-out date for coal. Electricity systems, however, are networks rather than collections of power plants.

New generation requires transmission lines, local distribution networks, storage, flexible demand, digital controls and dependable institutions capable of balancing supply. A country can auction large amounts of renewable capacity and still fail to deliver the electricity if the network cannot connect or absorb it.

Grid investment is particularly important because electrification lies at the centre of most decarbonisation strategies. Transport, heating and some industrial processes are expected to shift towards electricity while data centres and expanding cities add further demand. The electricity system must therefore become cleaner at the same time as it becomes larger and more complex.

This creates long lead times. Solar and wind projects can sometimes be developed relatively quickly, but major transmission infrastructure may take years to plan, permit and construct. Local opposition, fragmented regulation and shortages of equipment or skilled workers can delay projects further.

A climate pledge that assumes rapid electrification without a corresponding grid plan is therefore incomplete. So is an investment strategy that funds generation because it produces an identifiable return but neglects networks whose benefits are distributed across the wider economy.

The same problem appears in developing countries where utilities may be financially weak. Governments can attract private generation investment, but investors will remain cautious when the public or state-linked buyer cannot reliably pay for the electricity.

This is the third misalignment: climate policy often specifies what should generate the power without resolving how the system will deliver and pay for it.

The transition is being measured nationally but experienced locally

National emissions inventories are indispensable, but they can hide how transition costs and benefits are distributed.

Closing a coal-fired power plant may improve a country’s emissions trajectory while eliminating one region’s economic base. Introducing a carbon price may encourage cleaner investment but increase transport or heating costs for households without viable alternatives. Restricting land use may protect forests while reducing the income of communities that have few other assets.

These tensions do not invalidate climate action. They determine whether it survives politically.

A transition programme becomes vulnerable when governments announce the environmental objective before building the social settlement around it. Compensation is then introduced reactively after prices rise, jobs disappear or opposition hardens.

The more durable approach begins with the local economic question. Which jobs will be affected? What replacement industries are commercially plausible? Who owns the relevant land and infrastructure? Can workers reach new employment? Will households have affordable alternatives before a tax, ban or closure takes effect?

South Africa’s coal transition demonstrates the complexity. The country must reduce emissions from a carbon-intensive electricity system, but it must also improve unreliable power supplies and protect communities dependent on coal. International finance packages can support the shift, yet funding becomes politically fragile when local stakeholders see plant closures more clearly than they see replacement employment, grid improvements or community investment.

A mathematically efficient emissions pathway can therefore be politically and socially inefficient. Governments that ignore this may meet resistance not because voters deny climate risk, but because the proposed route concentrates costs on identifiable groups while presenting benefits as distant and collective.

This is the fourth misalignment: climate targets are aggregated nationally, while disruption is concentrated geographically and socially.

Development cannot be treated as an obstacle to decarbonisation

The climate debate sometimes assumes that rising energy demand in developing countries is the problem to be contained. That approach is neither politically credible nor ethically defensible.

Hundreds of millions of people still lack reliable electricity. Many more depend on energy systems that cannot support modern manufacturing, healthcare, refrigeration, education or digital services. Economic development will require more power, transport, housing and industrial output.

The relevant question is not whether these countries should consume more energy. It is how new demand can be met with cleaner, more efficient and more resilient systems than those used during earlier industrialisation.

That requires wealthy economies and multilateral institutions to treat development finance, climate finance and industrial policy as connected rather than separate agendas. A country cannot operate a low-carbon industrial strategy if it cannot finance ports, grids, schools and public administration. Nor can it maintain political support for conservation if rural communities do not share in the economic value created by protected land or carbon markets.

Policies should therefore be judged by their ability to produce several outcomes together: lower emissions, dependable energy, greater resilience, productive employment and rising living standards. A programme that achieves one objective while materially undermining the others is unlikely to remain durable.

This does not mean every climate policy must satisfy every development goal. It means governments should recognise the trade-offs rather than obscuring them behind aggregate targets.

What a credible climate pledge should contain

The next generation of climate plans must become more operational. A target should be accompanied by a capital plan showing what must be built, who is expected to finance it and what policy changes are required to make the investment viable.

Governments should separate projects that can attract commercial investment from those requiring concessional finance or grants. A utility-scale renewable project with a dependable buyer should not be financed in the same way as coastal protection for a low-income community. Treating both as a generic climate-finance requirement leads either to excessive public subsidy for profitable assets or chronic underfunding of essential public goods.

Energy plans should include transmission, distribution, storage and system-management requirements rather than listing only generation targets. They should also identify the cost of capital assumed in official modelling. A pathway built on financing conditions that the country cannot obtain is not a credible pathway.

Climate finance providers should report not only the amount committed but the amount disbursed, the proportion delivered through grants, the currency and repayment terms, and the development outcomes achieved. Counting a loan at face value can exaggerate the support received by a country that must repay both principal and interest.

Just-transition measures should be designed before closures and price reforms, not after resistance emerges. This requires local labour-market analysis, regional investment plans and transparent decisions about who bears the cost.

Finally, governments should distinguish clearly between unconditional climate actions they can finance domestically and conditional actions that depend on international assistance. This would make the global financing gap more visible and reduce the tendency to treat every unfulfilled commitment as a failure of national political will.

The world does not lack climate targets

The international climate process has succeeded in establishing a common direction. Nearly every government now accepts some version of the transition towards lower emissions and greater resilience. The weakness lies in translating that consensus into an investable, socially durable development model.

Current pledges, even if fully implemented, remain insufficient to prevent dangerous warming. Yet simply demanding a higher percentage reduction from every country will not solve the underlying problem. More ambitious targets unsupported by grids, institutions, affordable finance and public legitimacy may widen the distance between diplomatic commitments and physical delivery.

The next phase of climate policy must therefore be judged less by the elegance of its targets and more by whether it can answer practical questions. Can the electricity be delivered reliably? Can vulnerable countries finance resilience without worsening their debt burden? Can workers and communities see an economic future beyond high-carbon industries? Can private capital be directed towards places where development needs are greatest rather than merely where risk is lowest?

Until those systems are aligned, the world will continue producing climate pledges that improve on paper while falling short in the economies and communities expected to implement them.
