The carbon price is coming for your general waste. Northern Ireland is on a different clock.
On 26 August, the UK Government confirmed that energy-from-waste plants in Great Britain will not start paying for their carbon emissions in 2028, as had been planned. No new date was given.
Across much of the UK, that was read as a reprieve. In Northern Ireland, it changes less than it seems.
Under the Windsor Framework, energy-from-waste facilities in Northern Ireland come under the EU’s Emissions Trading System, not the UK’s. In July, the European Commission proposed putting a carbon price on burning waste from 2031, phased in to the full cost by 2034.
That matters more here than almost anywhere else in the UK. Between January and March this year, for the first time on record, Northern Ireland’s councils sent more waste for energy recovery than they sent for recycling.
The problem we thought we had solved
For most of the last two decades, the waste question for Northern Irish businesses was simple: keep it out of landfill.
On that measure, the region has done remarkably well. In early 2007, more than three-quarters of council-collected waste went to landfill. In the first quarter of 2026, it was 4.9%. Landfill tax, now £130.75 a tonne, made sure the economics pointed the same way.
The waste that left landfill did not disappear. Most of it became fuel. Residual waste is processed into refuse-derived fuel (RDF) and used to generate electricity, and energy recovery now handles 47.2% of council-collected waste in Northern Ireland.
For many businesses, the general waste bin has therefore become a settled cost line. Divert from landfill, report a good diversion rate, move on. That assumption now has a shelf life.
Carbon pricing is reaching the waste sector
An emissions trading system works simply. Large emitters must hold an allowance for every tonne of carbon dioxide they release, and those allowances are bought and traded at a market price.
When waste is burned for energy, roughly half the carbon released is biogenic, from food, paper and wood, and is not counted. The other half is fossil carbon, mostly from plastics and synthetic textiles. Industry analysis puts the fossil element at around half a tonne of CO₂ for every tonne of residual waste treated.
Bring energy from waste into a carbon market, and that fossil carbon acquires a price.
Two systems, two clocks
In Great Britain, the plan was to include energy from waste in the UK scheme from 2028. That is now on hold, with the Government saying only that a new timeline will follow “in due course”.
Northern Ireland is different. Both the UK ETS Authority and DAERA have confirmed that, under the Windsor Framework, it is the EU’s scheme that applies to waste incineration here. Northern Ireland’s facilities have been monitoring and reporting their emissions under EU rules since January 2024.
The European Commission’s proposal would phase in the obligation to pay from 2031: a quarter of emissions that year, rising each year to the full amount by 2034. It is still a proposal and must be agreed by the European Parliament and member states. The UK and EU are also negotiating to link their carbon markets, which could change how the two timetables fit together.
So the honest position is this. The date is not fixed. The direction is.
Why “zero to landfill” is no longer the full answer
For a decade, landfill diversion has been the headline waste metric in sustainability reports and tender responses. It is about to become an incomplete one.
A carbon price on energy recovery does not ask whether your waste avoided landfill. It asks what your residual waste contains. Two businesses can both report near-total landfill diversion and face very different carbon costs, depending on how much plastic is in their general waste.
The Chartered Institution of Wastes Management estimates that plastic packaging accounts for around 70% of the fossil carbon in residual waste. In other words, the material that drives the carbon cost is often the material that could have been separated in the first place.
None of this makes energy recovery the wrong answer. For waste that genuinely cannot be recycled, it remains far better than landfill. The problem is waste that ends up in the general bin by default.
What the numbers suggest
Nobody can yet say precisely what this will add to a waste bill. Free allowances, pass-through rules and the carbon price itself are all still to be settled. But the scale can be sketched.
EU carbon allowances were trading at about €82 a tonne in early October. At around half a tonne of fossil CO₂ per tonne of residual waste, that implies a carbon cost in the region of €41 per tonne at full phase-in, at today’s price. This is an illustration, not a forecast.
Analysis commissioned by SUEZ for the planned GB scheme reached a similar conclusion: including energy from waste in carbon pricing could raise treatment costs by around 50%.
Northern Ireland’s exposure is also higher than its recycling record suggests. The Climate Change Act (Northern Ireland) 2022 requires at least 70% of waste to be recycled by 2030. Councils recycled 50.4% of the waste they collected in 2024/25, while the share going to energy recovery keeps rising.
What this means commercially
Cost. Residual waste will increasingly be priced on what is in it, not just how much of it there is. Streams that are marginal to separate today, such as plastic film or rigid plastics, may become cheaper to recycle than to send for recovery.
Contracts. A multi-year waste contract signed in 2027 or 2028 could still be running when carbon costs begin. Finance and procurement teams should know how a change in law would be passed through before they sign, not after.
Reporting. Waste emissions sit in Scope 3 for most businesses. Once fossil carbon carries a market price, it becomes a cost line as well as a reported figure, and boards and auditors will ask how it is calculated.
Procurement. Much of the plastic in a business’s residual waste arrives as supplier packaging. Packaging specifications become a waste-cost decision.
Reputation. “Zero to landfill” will remain a useful claim. On its own, it will look increasingly thin to customers and investors who understand carbon.
What businesses should be doing now
The phase-in date gives Northern Irish businesses time. The ones that use it well will start with measurement, not bins.
