Why do we need to put a price on carbon emissions?

Why do we need to put a price on carbon emissions?

To address climate change and its associated costs, governments must implement carbon pricing mechanisms like carbon taxes and emissions trading schemes to hold polluters accountable for their emissions and fund future climate solutions; this promotes responsible investing and incentivizes a transition to green finance and renewable energy. Without carbon pricing, society bears the burden of pollution's heavy price tag.

If governments fail to implement effective carbon pricing, there is nobody to pay for the cost of pollution. Instead, they are left for future generations to handle. 

The heavy price of CO2

Many damages to compensate for 

Global warming causes harm in countless ways, and the damages we must address come in many forms and sizes:

  • Rising Sea Levels: Melting ice caps and glaciers are causing sea levels to rise, threatening coastal communities with increased flooding and erosion.
  • Extreme Weather Events: More frequent and severe storms, heatwaves, and wildfires are linked to climate change, resulting in devastating impacts on lives, infrastructure, and economies.
  • Biodiversity Loss: Rising temperatures and habitat destruction are causing many species to become endangered or extinct, disrupting ecosystems that provide vital services to humanity.
  • Agricultural Disruption: Changes in climate patterns affect crop yields, leading to food shortages and higher prices.

The future also comes with a carbon price tag

Addressing the climate crisis is not only about compensating for past mistakes but also about securing funds for the future. The Institute for Climate Economics estimates that there is a €813 billion climate funding gap to fill between 2024 and 2030. This gap is the difference in the financial resources needed to meet climate goals and the amounts that are actually invested to fight global warming.

To pay the bill, we must first put a price on carbon 

Since carbon emissions are a negative externality, if there is no governmental intervention, polluters will keep polluting, leaving society to deal with the resulting damages. In a free market, there is no economic incentive for CO2 emitters to compensate for their actions. To fix this, we need a carbon pricing system based on the 'polluter pays' principle, where those who release carbon emissions cover the costs of their actions.

The many ways to price carbon 

Carbon pricing mechanisms can take various forms, each with its own structure, size, and effectiveness:

  • Emissions Trading Schemes (ETS): An emissions trading scheme is a market-driven approach to controlling pollution by setting a cap on emissions and allowing businesses to buy and sell emission allowances.
  • Carbon Taxes: A carbon tax is a fee on the carbon content of goods and is proportional to the related volumes of CO2 - there is no limit on how much carbon can be emitted within an economy. 
  • Voluntary Carbon Markets: These allow businesses and individuals to purchase carbon credits to offset their own emissions. Those are structured through projects with the purpose of reducing, spring, or removing carbon from the atmosphere.

Without a price on CO₂ introduced by regulators, we will continue to see our homes flooded and our infrastructure destroyed; polluters must be held accountable for their actions.

UKAs and EUAs: Why Hold Both When You're Already Invested in European Carbon

If you're already invested in European EUAs, do you need to bother with UK UKAs? Short answer: yes. Long answer: the two markets are correlated at around 80% over time, but that correlation hides distinct dynamics (political, industrial, calendar-based) that make UKAs both linked and differentiated from EUAs. That's precisely what makes the combination interesting: an EUA core for liquidity and depth, a UKA satellite for political catch-up and the associated risk premium. Here's why.

What is the Climate Impact of a UKA? One Tonne of CO₂ Pulled Off the Market, Measured and Verifiable

Holding a UKA does something simple and radical: it takes one right-to-emit tonne of CO₂ off the UK market. Not an offset, not a voluntary credit, not a tree-planting promise. A regulated allowance, accounted for by the State, that exits the system the moment a non-compliance investor holds it. It's what we call an additional climate action: measurable, verifiable, legally framed. Here's how it works, and why this impact is one of the most robust in today's climate-finance landscape.

The UKA-EUA Convergence Play: Anatomy of a Catch-Up in Motion

May 2025, London summit: Keir Starmer and Ursula von der Leyen formally state their intention to link the UK ETS to the European system. A new term has been circulating among carbon analysts ever since: the Convergence Play. The mechanic is simple: UKAs trade today around 20% below EUAs, a discount that has already partially closed since May 2025. The residual mechanical upside is around +20 to +25%. Here's how it works, why it's happening now, and what the Swiss-EU precedent teaches us.
