Hi, I am a MSc student at Vrije Universiteit Amsterdam. I am looking into the EU ETS data, especially about freely allocated allowances, total allowances, and verified emissions.
However, when I download verified emissions and freely allocated allowances for all stationary installations on aggregate level, it is not the same as when I download the emissions per activity type, and then add the total verified and freely allocated emissions for all activity types.

Interestingly, the total amount of freely allocated allowances on the aggregate level is about twice as high as when I sum them for all activity types.

The verified emissions just differ in both ways, not by a specific fraction.

Now I was wondering, how is this possible, am I doing something wrong, or is there a better way to get this information?

See below the links to the data.

Then, another question relating to the Union Registry: What is exactly the meaning of Allocation_20xx? Is that the total allocation (free+auctioned+bought?), or something else? Same question for Verified_emissions_20xx, these numbers do not seem to coincide with the dataviewer. What data source is the most reliable one?

You would help me a great deal if you have answers to my questions. Thanks a lot in advance and have a great day.

Kind regards,

Dear Rene,

Thank you for contacting the European Environment Agency (EEA).
We acknowledge receipt of your request and will get back to you as soon as possible.

Dear Rene,

As you may have noticed the issue that you spotted was swiftly resolved by our IT team.

As regards your question on the Union Registry, we suppose that you refer to the Verified Emissions Excel file from the Union Registry documentation site. The information which is available from the Commission – both on that file and on EUTL ( – only includes free allowances. There is no information on auctioned amounts or even bought amounts of operators. You can only see surrendered amounts in information from the commission: every EUA which has been surrendered and which was not allocated for free has been bought – either directly from auctions or indirectly from other operators / bank institutes – whoever sells EUA. Information on bought amounts from operators from the latest three years is not available publicly.
The EEA data viewer adds the information of auctioned amounts, which is an important feature.
There are also small differences (e.g. for verified emissions) that always occur if you compare information with different extraction dates (when the data was extracted from the registry). Please note that the extraction date for our data viewer is the first working day of May, while some of the Commission files are from mid-April.

We hope that this may clarify the issue.

With kind regards,

Dear EEA Enquiry Service,

Thanks a lot for your response. I indeed saw updated data viewer, great!
I do not fully get what you mean, sorry. Is it correct to say that surrendered emissions are the total actually emitted emissions for an installation? And an installation will need to "own" that many allowances, which can either be gotten for free, or bought via auctions (direct) or indirect (via operators/bank institutes)?

About the Union registry: I am indeed referring to that one. In case that one is only about free allowances, what is the difference between for example "Verified Emissions_2019" and "Allocation_2019". I still do not understand where that difference comes from. If I want to see how many free allowances a company has gotten, which column is best to look at?

Hope to receive your answer!

Kind regards,
René de Koning

One additional question: "EU Allowance Deletion" in the column "Acquiring Account Identifier", does that equal the total emitted emissions per installation? Or what is the definition of this?

Thanks a lot for your effort, amazing!!

Dear M. Rene de Koning,

Verified emissions are the actual emissions from operators (i.e. companies or installations) in the context of the EU ETS. In order to be compliant, the operators must surrender a number of allowances (EUA) equal to these emissions. That’s why for the majority of operators: verified emissions = surrendered allowances.

Allocation_2019 are the EUA allocated for free to operators. If an operator surrenders more EUA than its allocation, it means they bought units. Therefore, the difference between verified emissions and allocation can be mainly due to 1) the operator trading or deleting EUA; 2) the operator not being able to surrender enough EUA to cover their emissions (non-compliant) or 3) a combination of both.

The EU Allowance Deletion is a system to remove allowances from the system. The idea is that by removing EUAs the pool becomes smaller and stimulates a general reduction in emissions. In our opinion, it has nothing to do with emissions per installation.

We hope that this answers your questions.
