Implications of the Carbon Border Adjustment Mechanism for the Iron & Steel sector

/0 Comments/in /by

On October 1st 2023, the Carbon Border Adjustment Mechanism (CBAM) became effective. As a measure to limit carbon leakage, the instrument complements the European Emission Trading System (EU ETS) by establishing a carbon price on imported goods that is equivalent to the carbon price on domestically produced goods. CBAM introduces a set of reporting and compliance obligations for importers of goods into the European Union.

Why is CBAM needed?

In a nutshell, CBAM is a policy instrument aiming to reduce the risk of carbon leakage under the EU ETS, the largest carbon pricing scheme worldwide that covers approximately 40% of the EU’s emissions. Carbon leakage refers to the phenomenon where climate policy restricts the competitiveness of domestic manufacturers compared to foreign producers that underly less stringent policies and can produce in a less expensive but environmentally more harmful way. The risk then arises that industry moves from the regulated jurisdiction to countries with lower environmental standards. Climate policy that does not manage carbon leakage could lead to the relocation of emission-intensive manufacturers abroad. Emissions would be exported instead of mitigated, and the domestic economy remains weakened.

Under the EU ETS, regulated entities, that are subject to the risk of carbon leakage, receive emission allowances free of charge conditional on their emission intensity in relation to a sectoral benchmark. This way, the competitive disadvantage of European climate policy is mitigated. The distribution of free allowances is phased out until 2034 and CBAM serves as a substitute to reduce the risk of carbon leakage for EU’s industry from there on.

What is the mechanism & scope of CBAM?

CBAM starts with a transitional period from October 2023 until end of 2025 with only reporting obligations for importers of certain goods. Importers or indirect customs representatives that transfer any CBAM goods into the EU, are obliged to calculate and report the embedded emissions that occur during the production process of CBAM goods and their precursors according to detailed rules.

The definitive period of CBAM starts in 2026. From then onwards, importers must purchase a proportional amount of CBAM certificates. The price of CBAM certificates is closely linked to the price of emission allowances in the EU ETS, momentarily around 85 Euro per ton of CO2e and expected to range between 100 and 150 Euro by 2030. Any carbon price due for the embedded emissions in countries of origin reduces the number of CBAM certificates to be surrendered (cf. figure 1). This mechanism assimilates the carbon price due for foreign and domestic goods that are sold on the EU market. Compared to the system of free allocations, CBAM not only increases the EU ETS revenues (free allocations of emission allowances are phased out), but also incentivizes ambitious carbon prices and industrial decarbonization abroad.

CBAM currently covers six EU ETS sectors accounting for roughly 50% of emissions in the EU ETS: aluminium, cement, electricity, fertilisers, hydrogen, and iron & steel. For now, in the iron & steel sector, 478 CN goods are combined into 8 aggregated goods categories that share similar production routes, system boundaries and precursors. The CBAM covers mostly emissions of CO2 but includes perfluorocarbons for aluminium products and nitrous oxide for some fertilisers. For the iron & steel sector, only CO2 emissions are relevant.

The European Commission will designate additional products further along the value chain of CBAM goods for potential inclusion in the regulation no later than by the end of 2024. Starting in January 2028 and subsequently every two years, the Commission will evaluate the overall effectiveness of CBAM and deliberate on the potential inclusion of additional sectors within CBAM.

What are the CBAM obligations for importers?

To fulfil their CBAM obligations, importers or indirect customs representatives must register as authorised CBAM declarants prior to the import of CBAM goods into the EU. For each calendar year, regulated companies must calculate the emissions embedded in imports following the methodology set out below and report the results through the CBAM declaration by May 31st in the following year. Within these declarations, the importers may also claim a reduction of CBAM certificates to be surrendered when a carbon price has been effectively paid in the country of origin. The information contained in the CBAM declarations must be validated by third party verifiers that are accredited under the EU ETS regulation. Importers must get access to the CBAM registry, the platform where data on embedded emissions is communicated to authorities and where CBAM certificates are bought, surrendered, and excess certificates are sold back to the authorities.

The obligation to surrender CBAM certificates is phased in until 2034. For the transitional period, no CBAM certificates need to be purchased. Starting with the definitive period in 2026, importers need to surrender CBAM certificates. The number of CBAM certificates to be surrendered, increases proportionally to the phase-out of free allocations in the EU ETS: in 2026 regulated companies have to surrender CBAM certificates for 2.5% of their embedded emissions. This share gradually increases until it reaches 100% in 2034.

How to calculate embedded emissions

The EU defined detailed rules for the calculation of embedded emissions. Generally, CBAM declarants must consider direct emissions from the production process as well as indirect emissions from the generation of energy used in the production process. The CBAM Directive lists some goods (also from the iron & steel sector) for which only direct emissions are to be considered as the production facilities benefit from EU compensation for higher electricity prices due to carbon pricing. For the actual calculation of direct emissions, obliged entities can follow either of the methodologies:

  1. The calculation-based approach where raw materials and inputs used in production are combined with calculation factors such as net calorific values or emission factors.
  2. The measurement-based approach where emissions are determined through continuous measurement of flue gas flow and greenhouse gas concentrations in flue gases.

When CBAM declarants lack the required data to perform the calculations they can revert to default values to be used as emissions factors. Default values are to be published by the end of 2023, the EU has however published a first study indicating the differences in emission intensities among the EU and its trading partners for CBAM goods (cf. figure 2).

Figure 2 GHG emission intensity for CN code 7217 10 – Wires of non-alloy steel. Value for Belarus is based on the secondary production route. Source: Vidovic et al. (2023).

CBAM declarants can also ask their suppliers to register themselves as an operator located in a third country within the CBAM registry. They may apply above calculation methodology to their output and obtain verification according to EU ETS standards. Suppliers can then disclose the information on embedded emissions to CBAM declarants who in turn may use this information within their CBAM declarations.

Which rules apply in the transitional period?

Acknowledging the challenges posed by the CBAM for declarants, the EU gradually implements the mechanism with a transitional period which started October 1st 2023 and ends December 31st 2025. The transitional period aims to function as a trial and educational phase for all involved parties, including importers, producers, and authorities. Its purpose is to gather valuable data on embedded emissions in order to improve the methodology for the definitive period starting January 1st 2026. CBAM obligations are reduced to reporting during the transitional period (cf. figure 3).

To increase the learnings during the transitional phase, instead of annual CBAM declarations, declarants must submit CBAM reports on a quarterly basis. The first report, covering the embedded emissions from the fourth quarter 2023 is to be submitted by January 31st 2024. The calculation and general reporting requirements are however somewhat eased for the transitional phase: In addition to the calculation methodology described above (EU Method), for the transitional period, two additional methodologies are available:

  1. Until December 31st 2024, embedded emissions can be determined through third country national systems such as carbon pricing schemes or monitoring systems whose accuracy and coverage is similar to the EU ETS.
  2. Until July 31st 2024, embedded emissions can be determined using only default values from the EU or elsewhere if calculation methodologies align.

For the transitional phase, all entities must report on both direct and indirect emissions. The exemptions for indirect emissions in the iron & steel sector mentioned above are only valid for the definitive period. Penalties can be imposed in cases where the reporting declarant fails to submit a correct or complete CBAM report or doesn’t rectify errors when initiated, with penalties ranging from EUR 10 to EUR 50 per tonne of unreported emissions.

What are the immediate tasks for companies?

The definitive period is two years away, however, here are the preparations companies should conclude at once to comply with the legal obligations of the transitional period and to get a head start for the definitive period:

  • Identify which of your imports are subject to CBAM regulations. Engage with suppliers and manufacturers to gather emissions data for imported goods. Collect information on carbon pricing schemes in countries of origin for your CBAM goods.
  • Get registered as CBAM declarant or have your indirect customs representative getting registered.
  • Get access to the transitional CBAM registry. This is the interface for regulators and regulated entities for the transitional period.
  • Learn how to handle the CBAM reporting template published by the EU.
  • Establish processes to collect emissions data and set aside personnel capacities to handle CBAM duties.
  • Make use of EU ETS allowance price forecast and embedded carbon projections to assess the medium-term economic implications of CBAM regulations on your supply chain and business.
  • Understand the implications of CBAM on your supply chain and assess your price and regulatory risk in different countries.

With the introduction of CBAM, emission monitoring and reporting along with carbon pricing plays an ever more important role for non-EU producers and importers. While the emission reporting obligations during the transitional period of CBAM are new to many companies and require comprehensive preparation, regulations on CBAM will evolve during the coming years and should be closely monitored by third country and EU producers as well as traders and importers alike. Details on CBAM implementation rules will for example still be required on the treatment of green electricity procurement through power purchase agreements in third-countries or on updated product lists subject to CBAM obligations. Ultimately, companies require a strategic approach towards these new realities of global trade and decarbonization.

Carbon management in Germany (II): emissions, potentials, and costs for CCUS

/0 Comments/in /by

In this second article of the series on carbon capture, use and storage (CCUS) in Germany, carboneer analyses the emission profiles of German industries and associated CCS potentials and costs. Review the first article on the developments around carbon management in Germany from a political and climate perspective here. Follow carboneer to access all articles, covering the general historical and political context of the topic, and highlighting developments and implications for the sectors steel, cement, lime, chemicals, and waste incineration.

Focus on industrial emissions

The energy sector, specifically electricity generation in coal and gas power plants, will most likely be excluded from any CCUS activities as the Carbon Management Strategy (CMS) of Germany is geared towards residual (hard-to-abate) and process-related emissions in the industrial sector. Still, the energy sector is the largest contributor to German CO2 emissions: In 2021 the energy sector emitted 238 Mt of CO2, accounting for 35% of total CO2 emissions. Most of the emissions from existing coal and gas power plants are however expected to be replaced by renewable sources or green hydrogen utilization, therefore limiting the scope for CCUS applications. Some potential however remains, mostly through CCUS applications in waste and biomass power plants.

The focus for CCUS activities will thus be on the industrial sector, the second largest contributor to CO2 emissions in Germany. In 2021, industrial facilities were responsible for 168 Mt of CO2 emissions, accounting for 25% of total CO2 emissions. The largest share of industrial emissions originates from large installations that are subject to the EU Emission Trading System as well as from waste incineration facilities. These installations emitted a total of 137.8 Mt CO2 in 2021 (cf. Figure 1), with largest contributions from steel production (31.5 Mt), waste incineration (23.3 Mt), cement production (20.1 Mt), the production of chemicals (16.9 Mt), and lime (6.4 Mt).

Figure 1: Sectoral shares of German industry (EU ETS facilities) and waste incineration CO2 emissions in 2021 (source: carboneer, data sources: DEHSt (2022), EEA (2022))

The CCS potential in the industrial sector in Germany

Three quarters of emissions in the industry are related to energy use and are to be abated using renewable energy. Approximately one quarter of the industrial emissions are process-related and originate from the utilization of carbon-containing materials in production. Process-related emissions are difficult to avoid and the five major climate neutrality studies for Germany (see part I) highlight the significant role of CCUS for emission mitigation or CO2-recycling in industry.

When calculating the CCS potential, it is important to notice that not all process-related emissions can be captured. Depending on industry and the dispersion of emission sources, the share of capturable emissions ranges from 45% in the chemical industry to 90% for waste incineration facilities. Following this methodology, the amount of technically capturable CO2 emissions from large industrial and waste incineration facilities in Germany amounts to 44.2 Mt (cf. Figure 2).

Figure 2: CCS potential in selected industrial sectors in Germany (source: carboneer)

Considering economic feasibility and alternative technological pathways for decarbonization, the ultimately relevant CCUS potential shrinks even further. While lime, cement, and waste incineration will need to capture CO2 due to a lack of technological alternatives, the use of green hydrogen may be the primary decarbonization route for steel production. The chemical industry will continue to depend on carbon-containing materials to produce basic chemicals, but might shift from fossil to biogenic and atmospheric sources, or build on recycled carbon from other industrial sectors. A more detailed analysis of the different sectors and their CCUS readiness will follow in future articles of this series.

Infrastructure and costs

To enable the transport of captured CO2 to potential storage sites or consumers, suitable infrastructure is necessary. The development of CO2 transport infrastructure is critical for the success of carbon management, and the pace of its development can significantly influence the entire progress of CCUS applications. By 2030, first large-scale CO2 transport infrastructures in Germany are necessary, where the mode of transport will depend on the scale and intended use of the CO2. Rail, trucks, ships, and pipelines can all be viable options. A pipeline connection is particularly useful for large industrial sites and CCUS clusters that generate significant amounts of CO2 to be transported over longer distances to storage facilities. However, for decentralized sites such as lime and cement plants, the most efficient handling of captured CO2 has yet to be identified. Local production of synthetic fuels is one of the possible options. A country-wide CO2 pipeline system connecting all major point sources is unlikely to develop, but pipelines for large industrial clusters will be necessary in the medium to long term. Furthermore, some oil and gas companies are already working on developing pipelines for exporting CO2 generated in Germany to storage sites in the North Sea.

While CCS costs (including capture, transportation, and storage) are relatively homogeneous across sectors, the current unavailability of storage capacity within Germany makes pure CCS implementation relatively expensive (cf. Figure 3) when compared to a country such as the United Kingdom, which has better access to storage sites (e.g. the North Sea). High costs of approximately 200 EUR/t CO2 for CCS applications in Germany already point at the need for incentive and support mechanisms to bring carbon management to an industrial scale.  

Figure 3: Average CCS cost in EUR/t CO2 in Germany and the UK (source: carboneer, data source: CATF, 2022)

Policymakers in Germany have to make the decision whether depleted natural gas reservoirs and saline aquifers in northern Germany and under the German North Sea are suitable CO2 storage sites, or if exporting CO2 through international collaborations and storing it in the North Sea and Norwegian Sea is a more politically acceptable option.

In the upcoming articles of this series, we investigate the attractiveness and readiness of the above industrial sectors for CCS applications based on indicators such as the regulatory framework, competing decarbonization options and other sector specific characteristics.

Carbon management in Germany (I): from zero to climate and industrial necessity

/0 Comments/in /by

This is the first article of a series on the potential of carbon capture, use and storage in Germany that will be published by carboneer over the coming weeks.

In this article, we look at the implications of a climate neutral Germany in 2045 on the demand for carbon management and carbon capture use and storage (CCUS). The topic has long been neglected in public debates but experiences a recent revival. CCUS can serve the dual purpose of (i) supporting the decarbonization of industrial facilities, and (ii) supplying especially the chemical sectors with CO2 as a resource for the production of primary products.

A brief history of carbon capture policy in Germany

While research on large-scale underground CO2 storage started in 2004 at the Ketzin pilot site close to Berlin, industrial carbon management activities (carbon capture, utilization and storage – CCUS) are virtually absent in Germany to the present. The European Union’s Carbon Capture and Storage Directive from 2009 provided its Member States with a framework to implement corresponding national legislation. The German Carbon Dioxide Storage Act (Kohlendioxid-Speicherungsgesetz – KSpG) came into force in August 2012 (cf. figure 1) but failed to establish favourable conditions for CCUS applications.

The storage discussion at that time in Germany was closely linked to the continuation of coal power generation and met strong public resistance. The expansion of renewable energy generation was at the center of potential mitigation pathways and CCUS applications were considered risky especially with regards to cost and safety criteria. Giving in to the general scepticism, the KSpG only allowed for applications with storage capacities below 1.3 million tons of CO2, and most states prohibited underground CO2 storage. No single storage project has been developed until the legal deadline for project submissions by the end of 2016. Currently it is therefore not possible to store CO2 underground in Germany and only a limited amount of capture and utilization projects are operative.

Carbon management has reemerged in the political arena in Germany only recently. The northwestern industrial state of North Rhine-Westphalia published its Carbon Management Strategy in 2021 and the National Carbon Management Strategy is currently being developed by the Federal Ministry for Economic Affairs and Climate Action (BMWK). We covered the national German Carbon Management Strategy in detail in this article.

Figure 1: Timeline and relevant events on carbon management in Germany (source: carboneer)

Carbon Management is a central component of climate neutrality

With tightening climate targets at EU and German level, it is becoming increasingly clear that climate neutrality by mid-century or even 2045 will not be achieved without large-scale capture, utilization and long-term storage of CO2. 

While CCUS experienced a slow uptake in German policymaking, academic research unanimously concludes that carbon management, including carbon capture, utilization and storage, as well as atmospheric carbon removal are necessary to reach climate targets. Since the electricity sector can be largely decarbonised through the expansion of renewables, the focus of carbon management in Germany lies on the industrial sector. Especially process-related emissions are hard to abate and might only be reduced through carbon capture solutions. Figure 2 shows the projections of five research projects on the sources of the CO2 that will be captured in 2045, at the time when Germany seeks to achieve climate neutrality.

Figure 2: CO2-capture according to application and source in 2045 (2050 for BMWK) (source: carboneer, data sources: Agora: Prognos, Öko-Institut, Wuppertal-Institut (2021), BDI: BCG (2021), dena: Deutsche Energie-Agentur (2021), BMWK: Fraunhofer ISI et al. (2022), Ariadne: Luderer, Kost and Sörgel (2021))

Building up the capacity to capture between 35 and 70 Mt of CO2 from different industries, or 5-10% of current German GHG emissions, requires targeted and substantial investments over the coming two decades. Investments will only materialize if determined policy making creates an enabling investment environment and delivers clear rules and guidelines on topics such as:

  • Incentive mechanisms for capture, utilization and storage
  • Transport and storage infrastructure provision and regulation
  • Regulation of CO2 imports and exports
  • GHG accounting (especially in utilization projects)

From waste to resource: how much storage is actually needed?

While we will take a deep dive into different industrial sector’s CCUS conditions and dynamics in upcoming articles of this series, we already want to draw your attention to some insights from our latest analysis. The technical potential across German industries predestined for CCS applications (steel, cement, lime, chemicals, waste incineration) amounts to 40-50 Mt CO2. Here we consider process-related emissions only, as other emission can and must be decarbonised through other solutions, such as renewable energy, electrification, or green hydrogen.

On the other side, the demand for carbon in the chemical industry in Germany in 2045 is estimated to be approximately 50 Mt CO2. This already points to a new paradigm and an industrial ecosystem, where CO2 will not necessarily be sequestered and stored underground in northern Germany, under the North Sea or even being exported to Norway, Denmark, or the Netherlands. Quite the opposite, CO2 might become a scarce a raw material in the industrial carbon cycle pushing the demand for CCU applications. Furthermore, the updated regulation on the EU Emission Trading System allows regulated entities to use CCUS instead of surrendering emission allowances. Undoubtedly, this option further increases the demand for CCUS applications.

Consideration of policy interactions and emerging new industrial paradigms are crucial for a successful carbon management at the national and EU level. Topics that require further analysis are amongst others:

  • Necessary CO2 transport capacity within Germany and Europe
  • Ultimate storage capacities needed across Europe
  • Quality criteria of CO2 for transport and utilization
  • Build-up of capture, transport and storage capacities in sync
  • Development of industrial carbon management clusters

The next article in this series on carbon management in Germany will deal with the current industrial emissions, the CCS potential in those industries and cost estimates for capture, transport, and storage. In the meantime, feel free to reach out with feedback and questions, which we are happy to discuss.

Carbon Management and CCU/S in Germany

/0 Comments/in /by

The German government is currently developing a Carbon Management Strategy for CO2 storage and utilisation. Because, one thing is indisputable: Without the capture, use and storage of CO2 from industrial processes (CCU/S) and the atmosphere, Germany can hardly become climate neutral by 2045. The basis for the Carbon Management Strategy is the new evaluation report on the Carbon Dioxide Storage Act. In this article, we explain the key points and principles of such a strategy.  

The CCU/S nomenclature

For the purposes of consistent nomenclature, we use the term carbon management below as an umbrella term for carbon management that includes CO2 capture, transport, and use (CCU) or storage (CCS) from fossil as well as biological or atmospheric sources as negative emissions or carbon dioxide removal (BECCS and DACCS). Likewise, dealing with other nature-based solutions to remove and reduce greenhouse gas emissions from the atmosphere is part of carbon management (see Figure 1).

Diagram Description automatically generated
Figure 1: Sources and sinks of CO2 emissions of the different components of carbon management (source: carboneer).

The impact on the climate and the technical and economic details of the different technologies and options are complex and require detailed analysis. Feel free to contact us for more information.

Carbon management necessary for climate neutrality

In early January 2023, German Economics Minister Robert Habeck travelled to Norway to explore further cooperation in the field of energy and climate. Among other things, the topic of CO2 capture, transport and storage is to become an important part of the cooperation with Norway. With tightening climate targets at EU and German level, it is becoming increasingly clear that greenhouse gas or climate neutrality by mid-century will not be achieved without large-scale capture, utilisation and, above all, long-term storage of CO2. 

At the same time, the German Federal Ministry of Economics and Climate Protection (BMWK) published the German government’s evaluation report on the Carbon Dioxide Storage Act (KSpG) in December 2022. The KSpG came into force in August 2012 and was intended to test the first demonstration projects for the long-term storage of CO2 in the ground in Germany. Acceptance of CO2 storage in Germany has always been very low in the past, especially as the discourse was strongly linked to the use of CO2 capture at coal-fired power plants and the continued operation of coal power plants. However, by the end of the application deadline for approval of new underground CO2 storage facilities (end of 2016), only one demonstration project had been applied for and been built in Germany. Since no new applications can be submitted after the end of 2016, underground CO2 storage is de facto not possible throughout Germany.

CO2 capture for residual emissions in industry

In the future, the use of CCS at coal-fired power plants in Germany is not expected to play a role due to the planned phase-out of coal. Capture, utilisation or storage of CO2 will however be needed primarily for a climate-neutral industry. Even after the use of renewable energies or electrification, large quantities of process-related CO2 emissions will still be produced, for example in the lime and cement industries or in the steel industry. Carbon is also the starting point for many other important products in the chemical industry and is therefore also needed as a raw material. The long-term scenarios project assumes that around 30 million metric tons of CO2 will have to be captured, transported, reused or disposed of in final storage by industrial plants in Germany even after climate neutrality has been achieved in 2045. Possible locations of capture plants and transport pipelines for CO2 are shown in Figure 2. 

Figure 2: Possible CO2 sinks, sources and transport pipelines in Germany in 2045 (source: Langfristszenarien)

Here, it is noticeable that clusters of CCU/S sites are located in the core areas of German basic and heavy industry. This clustering is mainly due to economic economies of scale for infrastructures for capture, transport but also the potential reuse of CO2. Accordingly, the focus of the German Carbon Management Strategy will be primarily on the industrial sector and not on capture in coal-fired power generation.

In addition to the capture of CO2 at industrial sources, however, the use of carbon removal solutions, i.e., the physical removal of CO2 emissions from the atmosphere, must also be developed. Carbon removal is the only way to offset the greenhouse gas emissions that will continue to occur in 2045, for example from agriculture. At 45-80 million metric tons of CO2, the negative emissions required are actually at a higher level than CO2 emissions to be captured from industrial processes. We have presented the details here and here.

Key principles of the German carbon management strategy

The use of CCU/S in industry will play a role as a decarbonisation option, alongside energy and resource efficiency and the use of green energy sources and electrification of processes. Key findings from the latest climate neutrality studies for Germany (Klimaneutrales Deutschland 2045, Klimapfade 2.0, dena-Leitstudie Aufbruch Klimaneutralität, Langfristszenarien) allow the following assessments:

  • Increase in ambition level of climate targets leads to increased use of CCU/S
  • CO2 capture in the million metric ton range necessary as early as 2030
  • Use of CCS mainly in industry and waste sector
  • Negative emissions from carbon dioxide removal must be scaled up from 2030 at the latest
  • Permanence of CO2 removal and storage by nature-based methods is uncertain and therefore makes technical solutions necessary as well
  • Fossil CCU/S and technical carbon dioxide removal can use the same infrastructures and should be considered in an integrated way
  • Transparent and continuous dialogue needed to ensure societal acceptance for ramp-up of CCU/S
  • Significant amounts of CO2 capture at global level (6-12 Gt/year depending on scenario) also driven by CCS at fossil power plants 

The recently published evaluation report on the KSpG provides the following key recommendations to the German government for revision: Examination and adjustment of regulations of the (cross-border) transport of CO2 and regarding German final storage sites for CO2, the further integration of CCU/S into the European Emissions Trading System (EU ETS), and the development of a clear framework for accounting of negative emissions. The details are to be elaborated in a German Carbon Management Strategy (Figure 3) by the German government, which will be presented during 2023. 

Figure 3: Basic pillars for carbon management in Germany (source: German government, adjusted by carboneer).

Which issues need to be clarified?

The German Carbon Management Strategy first aims to spell out a prioritisation of CCU/S applications. Questions must be answered for which industries and which emissions CCU/S measures are most important in order to use available resources in an appropriate manner. This should go hand in hand with the adaptation of the relevant regulatory framework, for example for approval procedures and the development and financing of (transport) infrastructures. Measures and funding programs in special application areas are also to be developed.

Methodologies for monitoring, reporting and verification (MRV) for CCU/S need to be developed. For example, the accounting of CCU/S in the EU ETS and the accounting for the use of CO2 from different sources (fossil, industrial cycle, biogenic, from the atmosphere) in the chemical industry and in the production of synthetic fuels must be clarified.

In particular, the possibility of transboundary CO2 transport will play a major role across the EU. In this regard, the Norwegian government has already made offers to the EU industry for accommodating their CO2 in underground storages in Norway. The design of pipeline and ship capacities as well as questions of EU network regulation and financing are important issues. The synergy effects of CCU/S clusters between industries as sources and sinks of CO2 must be elicited to find the most efficient solutions when planning infrastructures.

For possible CO2 storage facilities to become a reality also on German territory (probably rather under the seabed than under the mainland), social acceptance for CO2 capture and final storage must be built up. This can only happen through clear and transparent communication regarding the necessity of CCU/S for a climate neutral Europe and Germany.
