Green Claims in Online Gambling, and How to Check Them

Renewable power, certificates and offsets are three different commitments written as one sentence. What can actually be verified in an online casino's environmental claims - and what Erabet publishes on the subject.

Environmental language arrived in online gambling the way it arrived everywhere else: as a page, not as a change. Operators describe themselves as green, carbon-neutral, powered by renewables, paperless by design. Some of that reflects a decision somebody made and paid for. Most of it is a sentence. The difference is not a matter of opinion — it is visible in how a claim is worded, and almost all the work lies in knowing which words carry an obligation.

Where the energy actually goes

An online casino is not one machine, and its footprint splits into four parts that behave differently. The first is ordinary platform compute: accounts, wallets, databases, random number generation, the site itself. By the standards of the internet this is a mid-sized transactional application — not trivial, not remarkable.

The second is live dealer content, and on the operator side it is the heavy one. A live table is a physical studio with lighting, cameras and staff present around the clock, feeding a continuously encoded video stream to every seated player. Measuring the energy cost of an hour of streaming is genuinely contested, because the answer depends on how encoding, network transport and the viewer's device are split, so I will not attach a number to it. The ranking is safe even where the numbers are not: live tables dominate, slots barely register.

The third is the player's device and connection, which nearly every operator footprint excludes — defensible, but it means a published total is not the total. The fourth applies only if the site settles payments on a blockchain, and depends entirely on which network.

«Powered by renewables» is three claims in one sentence

When a company says it runs on renewable energy, it can mean any of three things, and the phrasing rarely distinguishes them.

Generation contracted to match the load. On-site generation, or a power purchase agreement signed for specific capacity. The strongest version, because the company has caused something to be built or kept running.

Unbundled certificates. Renewable energy certificates, guarantees of origin and their regional equivalents: the environmental attribute of renewable generation somewhere on the grid, bought separately from the electricity itself. The electrons arriving at the building are whatever the local grid delivered that hour. Legitimate accounting, and also the weakest form of the claim, because it is usually matched annually rather than hourly — so a site can be «one hundred per cent renewable» on paper while drawing from fossil generation on a still winter night.

Offsets. Not about electricity at all, but a payment for emissions reductions or removals elsewhere, used to net off the company's own. Quality varies enormously, and the two questions that decide it — whether the reduction would have happened anyway, and whether it lasts — concern the specific project, not the word «offset».

The phrase to look for is hourly or 24/7 matching as against annual matching; a company that has done the harder thing says so, because it costs more. Underneath sits a second question: an operator renting cloud capacity or colocation space is repeating somebody else's claim, and whose it is, on what terms, is fair to ask.

PUE: the one number that can actually be compared

Power usage effectiveness is total facility energy divided by the energy delivered to the computing equipment inside it. A value of 1.0 is the theoretical floor, meaning every unit of power reached a server; everything above it is cooling, conversion losses, lighting and the building. A facility at 1.5 spends half again as much energy as its servers consume in order to keep them running; at 2.0 it spends as much on the building as on the computing.

PUE is worth knowing because it is defined by a published standard, measured rather than asserted, and means the same thing in two different countries — close to unique in this field. Its limits matter as much. It is a ratio, so it says nothing about total consumption, and nothing about the carbon intensity of the grid: an efficient building on a coal-heavy grid scores well. It is sensitive to where the measurement boundary is drawn and to whether the figure is an annual average or the best hour of a cold month. And a casino almost never owns its data centre, so a PUE in a gambling company's materials is a supplier's number passed along.

Proof-of-work, proof-of-stake and the one documented difference

Blockchains differ in energy use by design rather than by efficiency. A proof-of-work network secures its ledger by making block production expensive: participants compete by performing enormous volumes of computation, and the security budget is spent, literally, as electricity. That is the mechanism working as intended, which is why it does not fall as hardware improves — better hardware simply raises the competition. Proof-of-stake replaces the race with capital at risk: validators are selected to propose and attest to blocks, and misbehaviour costs them their stake. No competition to win means no hashing load to pay for.

The size of that difference is one of the few figures here worth quoting, because it is documented and public: Ethereum switched from proof-of-work to proof-of-stake in September 2022, and the change reduced the network's electricity consumption by roughly ninety-nine per cent. Not a projection or a target, but a step change in a live network, measured after the fact.

For a player this cashes out narrowly. If the footprint of a deposit matters to you, the network you send it over matters far more than the brand you send it to, and no casino can claim credit either way. The payment mechanics themselves — what crypto speeds up, what it costs and what it leaves untouched — I worked through in the piece on crypto in casinos.

Paperless is a rounding error

«We have gone paperless», «digital receipts», «no printed statements» — in a business born digital that never issued a paper statement. Such claims describe the absence of something that was never there: they cost nothing, change nothing, and exist because they are easy to write. The working rule is that a commitment costing the company nothing and requiring no decision is communication rather than policy. That is not the same as calling it dishonest; it is simply not evidence. The same goes for a tree planted per registration unless the accounting behind it is published.

How to tell a report from a brochure

Six things separate a disclosure that can be checked from one that cannot, and none requires technical knowledge to spot.

• A stated boundary. What is counted and what is excluded — player devices, streaming delivery, third-party game studios. A report that does not draw its own edges cannot be compared with anything.
• A method and a base year. Which accounting standard, which emission factors, and whether electricity is reported market-based, location-based or both. A report giving only market-based figures is describing its contracts rather than its grid, and that one detail explains many perfect scores.
• Absolute numbers beside the ratios. Intensity improvements and total growth are compatible: energy per player session can fall while total consumption rises. A report offering only per-unit figures has chosen the flattering half.
• Named verification. Third-party assurance, its level stated and the assurer named. «Independently verified» with no name attached is a phrase, not an audit.
• A date. An undated sustainability page is one nobody has maintained since it was written.
• A legal entity taking responsibility. A commitment with no identifiable party behind it commits nobody.

One missing item proves nothing. All six missing means there is nothing to examine, whatever the page says about the planet.

What Erabet publishes on this

Applying that checklist to the brand this site covers takes very little time, because there is nothing to apply it to. As of 23 September 2026 the operator publishes no environmental claim of any kind: no sustainability page, no report, no statement about energy, hosting, data centres or the networks it settles payments on. There is no green record here to praise and none to criticise — there is an absence. That is worth stating plainly, because the opposite mistake is common: review sites reward brands for language that costs nothing to write and penalise the ones that stayed quiet, which gets the incentives backwards. Silence is not a failing grade; it is an absence of information.

The surrounding context is more informative than the silence. The same site names no legal entity anywhere, and its footer reads «© 2026 .» — a year, a space and a full stop, with the company name that belongs between them missing. Its terms cite a Curaçao master licence numbered 8048/JAZ; the licence holder's own validator, checked the same day, replied that it cannot verify the licensing status of the site. An operator that has not published who it is was never going to publish its energy mix, and if it did, the disclosure would carry precisely the weight of its source. The rest of what the site does and does not say is set out in the review.

The short version

Live video, not slots, is where an online casino's own energy goes, and blockchain settlement is a separate load depending on the network rather than the brand. «Renewable» covers contracted generation, annually matched certificates and offsets — three very different commitments written as one sentence. PUE is the only readily comparable number, and it belongs to a data centre operator rather than a casino. The proof-of-work to proof-of-stake difference is real and documented; paperless operations are worth approximately nothing. Everything else depends on whether the claim arrives with a boundary, a method, a date and a name.

A reassuring story repeated often enough starts to function as evidence long before anyone checks it — the same mechanism that kept gambling superstitions alive for centuries, which I went through in the piece on ancient gambling myths. The correction is identical in both cases: ask what would have to be true, then ask who published it.
