The enormous, seemingly insurmountable costs of transitioning to a climate-neutral world represent one of the greatest challenges of our time. According to the financial plans of the UN Framework Convention on Climate Change campaign (UNFCCC) Race to Zero will require up to $125 trillion to achieve this goal by 2050. This astronomical sum creates a sense of helplessness and presents us with a global challenge that requires innovative sources of financing, including direct taxation of the industries responsible for the crisis.

Recent in-depth study But a study by the European Commission has revealed some surprising and counterintuitive ways to raise these funds. It turns out that the answer doesn’t necessarily lie in complex global agreements, but in more targeted strategies. This article brings together the key findings from the report, showing how small groups of countries, old legal clauses and even tackling plastic pollution are central to the future of climate finance.

To achieve big goals in climate finance, start small

One of the report’s most surprising conclusions is that „plurilateral“ approaches – coalitions of willing countries – are seen as „most feasible and promising“ for introducing new climate taxes and levies. This finding is in direct contrast to the common assumption that the ideal is global, almost universal agreements involving all countries in the world.

A message This approach is very clearly justified:

Plurilateral implementation of each instrument is considered the most feasible and promising, as it is more likely to be agreed quickly by a critical mass of countries and lead to ambitious outcomes, … as opposed to a global agreement, which tends to be a watered-down compromise, insufficient to achieve the objectives and potentially blocking further negotiations…

The significance of this finding is enormous. Global agreements are often „watered down“ because they have to find the lowest common denominator acceptable to nearly 200 countries, which inevitably stifles ambition. The report suggests that progress does not have to wait for every single country to agree. Instead, smaller, more ambitious groups of states can take the lead, create workable models, show the way for others, and avoid the risk of blocking further negotiations.

The numbers are bigger than you can imagine.

While the political hurdles to implementing new international levies are high, the potential financial benefits for climate action are enormous. The report analyses several instruments whose revenue-generating potential shows that the necessary funds can be raised – often directly from the sectors that contribute most to the climate crisis.

Here are some of the estimated annual revenues:

• Fossil fuel extraction levy: A global levy that would start at the level only 5 USD per ton of embedded CO2, could generate an estimated $215 billion and in 2035, peak at $1,015 billion.
• Tax on extraordinary profits: A one-time temporary global levy of 33 % on extraordinary profits made in 2022 could generate approximately $716.1 billion.
• Drainage from plastic polymers: A global levy, based on the existing EU precedent of €0.80/kg, could mobilise an estimated EUR 22 to 34 billion.

These figures clearly demonstrate that the financial resources to address the climate crisis exist. The key is to create the political will to put in place mechanisms that redirect these resources from polluters to financing solutions.

Ancient legal clauses are a modern climate threat

One of the biggest, yet least known, obstacles to introducing new climate levies is not only political resistance, but also subtle legal texts hidden in old investment contracts. These are the so-called „fiscal stabilization clauses.“.

The report defines them as provisions often found in treaties in developing countries that protect investors by limiting the government’s ability to change tax laws after an investment has been made. In other words, these clauses „freeze“ tax conditions for decades to come. The report makes it clear that these clauses represent „a potentially huge obstacle to the introduction of new levies.“

This insight is crucial because it shows that the path to climate finance requires not only the creation of new policies, but also a form of legal archaeology – that is, uncovering and neutralizing decades-old agreements that were made without regard for the climate and are now actively hindering progress.

Fighting plastic pollution could fund climate action

The report proposes a levy on plastic polymers that would target the production of primary (so-called virgin) plastics from fossil fuels. This idea takes on added importance when we consider the scale of the problem: plastic production has grown from „2 million tonnes in 1950 to 400 million tonnes in 2022“ and is expected to almost triple by 2060.

Such a levy would have two benefits. First, it would generate a „stable and predictable source of finance.“ Second, it would apply the „polluter pays“ principle to an industry whose environmental costs are enormous. This is a transformative idea: we can use a financial mechanism designed to address one major environmental crisis (plastic pollution) to directly fund the fight against another (climate change), creating a powerful narrative of interconnected solutions.

That this is not a theoretical concept is also proven by a real example. The European Union has already introduced the so-called "own resource from plastics", which is a fee of €0.80 for each kilogram of unrecycled plastic packaging waste. This mechanism confirms that plastic taxation is a feasible and functional tool.

Conclusion: The question is not whether we can afford it

As this groundbreaking study shows, the path to climate finance lies not through waiting for a global consensus, but through bold coalitions of the willing, targeted taxation of polluters, and legal confrontations with the remnants of the past. The real message of the report is that the obstacles to climate finance are no longer technical or financial, but almost exclusively political.

When these innovative financial instruments are discussed, the real question becomes not whether we can afford climate action, but whether we can afford the costs of inaction. JRi
