4. Does UK ETS have a separate Registry account?
Yes, the UK ETS registry is used to record the below information under UK ETS only:

> Free allowance allocations
> Annual verified aviation emissions
> Allowance transfers
> Allowance surrenders

The registry administrator will open an Aircraft Operator Holding Account (AOHA) in the UK ETS registry after the UK ETS regulator has issued and confirmed the Emissions Monitoring Plan (EMP). The administrator will contact the aircraft operator accordingly. This is the aircraft operator’s responsibility to maintain the AOHA and nominate two authorized representatives for the AOHA.

5. Would offsets be included in the UK ETS?
No, offsets are not to be included in the UK ETS. Currently, emissions are compensated using allowances that are eligible units that can traded through the UK ETS registry.

The use of Offsets for CORSIA emissions reported to the UK authority is still under consideration.

6. What is the UK ETS’s aviation cap on emissions?
The Authority have decided to reset the UK ETS cap for 2021-2030 to make the UK ETS consistent with UK’s trajectory towards Net Zero by 2050.
