Discussion

Sam Dewinski:

The fairest judgment is mixed. COP has been more successful at building institutions and changing political expectations than at delivering emissions reductions on schedule. The Paris Agreement created a nearly universal system of national climate plans, transparency reporting and five-year global stocktakes. That is a major diplomatic achievement, but it does not impose a centrally enforced emissions cap or automatic penalties. COP has created accountability; it has not created a world government capable of implementation.

Kate Burvish:

Climate finance shows the same pattern. Developed countries reported 132.8 billion dollars in 2023 and 136.7 billion in 2024, exceeding the earlier 100-billion-dollar annual goal. But that goal was supposed to be met in 2020, and the totals combine public finance with private finance mobilized by public interventions, including different mixes of grants and loans. The headline is progress, but the practical questions are whether money is affordable, accessible and directed toward the countries and projects with the greatest need.

Sam Dewinski:

There were important breakthroughs as well. COP27 created funding arrangements and a fund for loss and damage in vulnerable developing countries, and COP28 operationalized them. COP28 also produced the first negotiated language calling for a transition away from fossil fuels, alongside calls to triple renewable capacity and double the rate of efficiency improvement by 2030. Those commitments changed the political vocabulary. They are not, however, a binding fossil-fuel phaseout schedule, and the loss-and-damage fund still depends on capitalization and access.

Eric Arcan:

The physical record is less reassuring. The first global stocktake found that progress had been made, but collective efforts were insufficient and the world was not on track for the Paris goals. Renewable deployment is accelerating, yet current-policy forecasts put 2030 capacity at roughly 2.6 times 2022 levels, short of the tripling target. So this is not total failure. It is a process that has helped accelerate investment while still missing its own timetable.

Red Velhouse:

So the recurring gap is between negotiated direction and the domestic work of building, financing and operating the system. Sam, is that a familiar pattern in international politics?

Sam Dewinski:

Very familiar. International systems often establish reporting rules and recurring reviews before they produce matching outcomes. Those procedures matter because they change what governments must explain to one another and to their publics. But climate policy has a long implementation chain: permitting, utility regulation, industrial policy, finance and public acceptance all have to align. No international body can order a transmission line or close a coal plant. Institutions without domestic execution become elaborate reminders of what governments promised.

Kate Burvish:

And aggregate finance can coexist with practical failure. Organisation for Economic Co-operation and Development reporting put support for low-income countries at 9.6 billion dollars in 2024, below the 20 percent share associated with an earlier commitment to least-developed and low-income countries. Developing countries therefore ask whether money is a grant or a loan, how quickly it can be accessed, whether it adds debt and whether it supports adaptation, where commercial returns are often weak. The dispute is about the quality and distribution of capital, not just volume.

Red Velhouse:

That brings us to COP31’s implementation agenda. The presidency is promoting a voluntary 35-by-35 pledge to raise electricity’s share of final energy consumption from about 21 percent to 35 percent by 2035. Eric, what has to happen for that to be more than another target?

Eric Arcan:

Electrification is only as useful as the system behind the plug. Electric vehicles, heat pumps, industrial equipment and electric cooking require transmission, distribution, storage, system-strength investments and reliable generation. The International Energy Agency estimates that annual global grid investment must rise by about 50 percent from roughly 400 billion dollars today by 2030. In some markets, renewable generation is already being curtailed because the grid cannot move or balance it. Generation can outrun the network’s ability to use it.

Kate Burvish:

That is where the cost debate often goes wrong. Levelized cost of electricity, or LCOE, measures the average cost of generating electricity from an individual project. The International Renewable Energy Agency, or IRENA, reported about 34 dollars per megawatt-hour for new utility-scale onshore wind in 2024 and about 43 dollars for new solar photovoltaic power. It said 91 percent of newly commissioned utility-scale renewable capacity was cheaper than the cheapest new fossil alternative on that measure. Those are strong results, but they are not a complete electricity-system bill.

Eric Arcan:

Exactly. Low project-level generation cost is not the same as reliable electricity delivered every hour. Solar falls after sunset, wind can be weak across a broad region, and both may produce when the grid has little room. A whole-system comparison may require transmission, interconnection, grid reinforcement, balancing, reserves, storage, demand response, firm capacity and the cost of curtailment. Some upgrades would be needed for any modern grid, but infrastructure required to make electricity useful still has to be counted.

Red Velhouse:

When people ask whether renewables can compete with fossil fuels without subsidies, the answer depends on what they mean by compete. Kate, take the new-generation comparison.

Kate Burvish:

For many new-build projects, they can. Lazard’s 2025 United States estimates put unsubsidized utility solar at roughly 38 to 78 dollars per megawatt-hour and onshore wind at roughly 37 to 86 dollars. Its ranges for new coal were about 67 to 179 dollars and for combined-cycle gas about 41 to 116 dollars. These are illustrative, not universal, but they explain why solar and wind can beat new fossil generation where resources are good, grid access is reasonable and financing is manageable.

Eric Arcan:

The claim becomes more conditional when we ask for firm supply. Lazard estimated solar paired with four-hour storage at about 50 to 131 dollars per megawatt-hour and wind paired with four-hour storage at about 44 to 123 dollars. Those ranges can overlap fossil generation, but four hours does not guarantee supply during a multiday wind lull, a prolonged winter event or a seasonal shortage. Batteries are valuable, but they do not turn variable output into unlimited firm power.

Kate Burvish:

Financing can be as decisive as technology. Wind and solar pay most costs up front and have minimal fuel costs, while gas generation carries more costs through fuel over time. High interest rates and country risk therefore hit renewables disproportionately, especially in emerging economies. Guarantees, concessional finance and currency-risk protection can lower that barrier. They can address market failures that otherwise make a socially valuable project look unbankable.

Eric Arcan:

Geography matters too. Onshore wind and solar at high-quality sites with nearby grid capacity are the clearest unsubsidized cases. Offshore wind is more conditional: IRENA put its 2024 global weighted-average LCOE at about 78 dollars per megawatt-hour, higher than its averages for onshore wind and solar. It may still make sense where land is scarce or diversity is valuable, but it faces greater construction, supply-chain and interest-rate risks. There is no single renewable price or fossil price.

Red Velhouse:

Critics say system costs prove renewables are not really cheap. Supporters say grid and storage spending is overdue modernization needed for electrification anyway. Which part of each argument survives?

Eric Arcan:

Both sides identify part of the problem. Higher shares of variable renewables can require more transmission, flexibility, reserves and storage, and can reduce the market value of additional output when it arrives simultaneously. But grids, interconnections and demand flexibility are also infrastructure for electrification, resilience and energy security. The rigorous question is which investments are caused by a renewable project, which would be needed anyway, and which options provide reliability at least cost.

Red Velhouse:

Energy security makes the choices harder. Conflict can disrupt oil and gas markets, while governments still need dependable energy. How should policymakers avoid turning emergency measures into long-term lock-in?

Eric Arcan:

Separate emergency reliability from permanent lock-in. Efficiency, domestic renewables, storage, diversified generation and stronger grids can reduce exposure to imported-fuel shocks. But systems cannot be redesigned overnight, and a government facing a crisis may subsidize fossil fuels to keep people warm and factories operating. The danger is when temporary measures become permanent infrastructure. Every investment should improve reliability now while preserving affordable options for a cleaner system later.

Kate Burvish:

Affordability must be part of that test. High interest rates and country risk can raise the cost of capital for renewable projects, even when their operating costs are low. That can make a project appear unbankable in an emerging economy while a gas project benefits from established fuel markets or different financing conditions. Guarantees, concessional finance and currency-risk protection can reduce that barrier, but policymakers still need to ask whether support improves access and reliability at a reasonable public cost.

Red Velhouse:

What should viewers watch for at COP31 if they want evidence of implementation rather than another declaration?

Sam Dewinski:

Look for an observable trail: national plans tied to 35-by-35, permitting reforms, grid milestones and finance arrangements with clear responsibilities. The strongest agreements are not necessarily the ones with the most dramatic sentences. They are the ones that establish reporting, review and follow-up, making evasion more visible.

Kate Burvish:

For finance, watch the terms rather than only the total. Are grants and concessional finance increasing? Are guarantees lowering borrowing costs? Are low-income countries receiving a larger share? Are projects reaching construction? The inherited framework includes a developed-country-led goal of at least 300 billion dollars annually for developing countries by 2035 and a broader call to scale total finance toward 1.3 trillion. Those figures have different scopes, and neither proves that electricity or adaptation is affordable.

Eric Arcan:

For energy, watch whether renewable targets are paired with transmission, distribution, storage, system strength, demand flexibility and reliable capacity. Renewables are already cost-competitive without direct subsidies for much new generation, especially solar and onshore wind in good locations. But the stronger claim that they are always cheaper for reliable electricity service is not supported by plant-level LCOE. The winning system delivers affordable power through calm nights, cloudy weeks, construction delays and unexpected demand.

Red Velhouse:

COP’s record is neither a clean success nor an empty exercise. It built a nearly universal reporting and review framework, created important political signals on fossil fuels and renewables, and eventually exceeded the earlier 100-billion-dollar climate-finance target. It also missed deadlines, left finance uneven and insufficiently accessible, and failed to put the world on track for its temperature and deployment goals. On costs, unsubsidized solar and onshore wind can compete with new fossil generation in many favorable applications. But reliable electricity is a system service, so grids, financing, storage, flexibility, firm capacity and external costs matter. COP31 is testing whether diplomacy can connect those facts to infrastructure that is actually financed and built.
