2.6 The ETS Directive
The Emissions Trading System Directive (ETS Directive) establishes the EU Emissions Trading System (EU ETS). The ETS Directive also falls under the EEA Agreement. There are connections between the EU ETS and CCS and their respective directives. In short, the EU ETS creates a system where certain operators must own emission allowances for GHG they produce and emit. Annex I of the ETS Directive sets out which activities that are included in EU ETS and includes both activities such as power generation but also the capturing and transportation by pipeline of CO2 from installations covered by the Directive and the geological storage of CO2 in a storage site. Article 12(3a) of the ETS Directive sets out that an obligation to surrender allowances shall not arise in respect of emissions verified as captured and transported for permanent storage to a facility for which a permit is in force in accordance with the CCS Directive. Since under the CCS Directive, only storage facilities in the EEA can obtain a permit, storage outside the EEA cannot comply with the requirements of Article 12(3a).
The EU ETS may provide economic feasibility for CCS applied to emissions from fossil fuels in the EU provided that the price of emission allowances (called EU Allowance Units, EAUs) is sufficiently high relative to the cost of CCS. The EU ETS is based on allowances rather than credits and thus does not provide incentives for BECCS regardless of the EAU price. Allowing the use of BECCS credits for the purpose of compliance in the EU ETS would require significant revisions not only to the EU ETS, but also to the effort sharing regulation (ESR) and the land use, land use changes, and forestry (LULUCF) Directive.
Through an Implementing Regulation (Monitoring Regulation), the Commission has set out rules for the monitoring and reporting of GHG emissions and activity data pursuant to the ETS Directive. According to article 49 of the Monitoring Regulation, CO2 originating from fossil CO2 in activities covered by the ETS Directive that is not emitted from the installation but instead transferred to a capture installation, a transport network or a storage site is to be subtracted from the emissions of the installation. A “transportation network” is defined in the Monitoring Regulation as it is in the CCS Directive, namely as “the network of pipelines, including associated booster stations, for the transport of CO2 to the storage site”. This clearly does not include transportation by shipping. The consequence is that CO2 that is captured and transported through shipping is not eligible to be subtracted from the emissions of the installation. This is of particular significance in a Nordic context as according to current plans, a significant part of the transportation of captured CO2 will be through shipping.
As part of the ongoing revision of the ETS Directive, however, the Commission has proposed to extend the provision for transport of CO2 for geological storage “by pipelines” to all means of transport. It is however not until CO2 has been transferred from other means of transport to a transportation network that is fixed to a storage site that the capturing installation can subtract the CO2. Furthermore, a paper from the Commission published in 2022 states that “for concrete cases, the Commission, already today applies a broad interpretation so that the transfer of captured CO2 to a ship or a truck does not prevent the right to subtract the CO2 when it is later on transferred from the ship or the truck to a pipeline transport network or directly to a storage site. When that later transfer from the ship or truck to the network or storage site is completed, the capturing installation can subtract the CO2 according to Article 49 (a) (ii) or (iii) of the Monitoring and Reporting Regulation 2018/2066”. It is also worth noting that the TEN-E regulation (Annex II) acknowledges ship as one mode of CO2 transport along with pipeline, barge, truck and train.
In a letter to the Commission, Norway has asked if the transfer of captured CO2 to a ship or a truck prevents the right to subtract the CO2 when it is later transferred from the ship or the truck to a pipeline transport network or directly to a storage site. The Commission answered that in view of article 49 of the Monitoring Regulation and the ETS Directive, an operator should be allowed to deduct any CO2 intended for an offshore storage facility from its emissions, which is consistent with the position presented in the paper from the Commission published in 2022. A second question that Norway posed to the Commission in the letter was if CO2, regardless of fossil or biogenic origin, can be subtracted from the emissions of the installation as long as it does not exceed the installation's total amount of produced fossil CO2. The Commission answered that that captured CO2 from biological origin may not be subtracted from the emissions of the installation as there is no legal ground in the ETS Directive to support this. The Commission further states that article 49(1) of the Monitoring Regulation makes it clear that this is not possible “("The operator shall subtract from the emissions of the installation any amount of CO2 originating from fossil carbon […]")”. The Commission deems however, that other instruments could address the issue of and create incentives for BECCS in a more efficient way.
In conclusion, as of the wording of the ETS Directive and the Monitoring Regulation captured CO2 of biogenic origin from one installation cannot be deducted from the CO2 emissions from the same installation. However, contrary to the direct wording of the ETS Directive and the Monitoring Regulation, captured fossil CO2 transported by other method than pipeline, such as by ship, intended to be stored in a sub-seabed geological formation, can be deducted from the installations emissions from where it came as soon as it is stored.
Questions have been raised concerning the distribution of risk and liability between parties, e.g., Weber (2020). As noted by Weber, when CO2 is transported by pipeline, the CO2 producers’ risk goes, in accordance with the provisions of the ETS Directive and the Monitoring Regulation, to the storage operator as soon as the CO2 is handed over. However, the current regulation does not provide the same clarity when other modes of transportation are involved. A paper from the Commission published in 2022 clarifies that in order to make the calculation consistent in the case of a “CCS value chain” (i.e. several installations together performing the capture, transport and geological storage of CO2), the receiving installation has to add that CO2 to its emissions, before it may again subtract the amount transferred to the next installation or to the storage site. In other words, the liability for emissions caused by the operation of CO2 capture, transport or storage in the CO2 value-chain is transferred from one ETS installation to the other, without regard to the EEA country they are located in. Any leakage from storage is thus accounted as an emission by the storage operator, and also reported by the country where the storage site is located, in its national GHG inventory.
