Change 7 Substance
AI summary:Removes recitals 6c, 6d, and 6e, and adds new provisions on invalidation of allowances from 2034, distribution of releases over three months, and a Commission impact assessment within four years.
Show the text change (9 lines)
Removed:Recital 6 c (new): (6c) The Union might be confronted with sudden and severe disturbances affecting the availability, affordability or security of energy supply due to large-scale blackouts, significant disruptions of electricity or gas systems, natural disasters, deliberate acts of sabotage against European energy infrastructure, geopolitical conflicts, or other exceptional events beyond the control of Member States. In extraordinary circumstances, sharp and temporary increases in allowance prices may aggravate existing economic and social pressures and risk undermining the orderly functioning of the Union's emissions trading system. The changes introduced by this amending Decision are not primarily aimed at enhancing the ability of the market stability reserve to mitigate such exceptional circumstances in the long-term. It is therefore appropriate, for strictly exceptional situations, that a stronger emergency mechanism be assessed by the Commission which would introduce an additional stronger price ceiling for a limited period of time. This needs to be done in a manner that does not negatively affect fulfilment of the Union’s long-term climate objectives as well as the reduction of emissions within the scope of the emissions trading system for the buildings, road transport and additional sectors.
Added:Recital 6 b (new): (6 b) Following the revision of the market stability reserve provided for in this amending Decision, it would be appropriate for the Commission to conduct an impact assessment of the emissions trading system for the buildings, road transport and additional sectors to assess its social impact and its impact on meeting the climate goals, as well as a distributional assessment of the number of vulnerable households for which support has been made available from the Social Climate Fund and the Frontloading Facility by that date, including, as feasible, a breakdown by type of geographical area, by income distribution and by gender which needs to also consider additional measures to ensure both environmental integrity and social fairness within the ETS2.
Removed:Recital 6 d (new): (6d) In order to increase certainty for citizens, before the beginning of the operation of emissions trading for buildings, road transport and additional sectors, it is important that the Commission presents a report to the European Parliament and to the Council assessing whether the excessive price control mechanism referred to in Article 30h(2) of Directive 2003/87/EC is adequate, based on the early auctioning of allowances.
Added:Article 1 – paragraph 1 – point 1, Article 1a of Decision (EU) 2015/1814: (1) In paragraph 3, the second sentence is replaced by the following: ‘From 1 January 2034, 50% of the allowances referred to in that subparagraph that have not been released from the reserve shall no longer be valid. From 1 January 2036, the remaining allowances referred to in that subparagraph that have not been released from the reserve shall no longer be valid.’
Removed:Recital 6 e (new): (6e) In order to enhance predictability and certainty of the Union carbon market for the buildings, road transport and additional sectors, the Commission considers that, if the condition in Article 30h(2) of Directive 2003/87/EC is met again after six months, paragraph 6 of Article 30h should be disapplied in accordance with the procedure set out in paragraph 7.
Added:Article 1 – paragraph 1 – point 4 a (new), Article 1a of Decision (EU) 2015/1814: (4 a) In paragraph 7, the second sentence is replaced by the following: / "‘The volumes to be released from the reserve shall be evenly distributed over a period of three months, starting no later than 30 days after the date on which the conditions were met according to the publication in that regard in the Official Journal of the European Union pursuant to Article 30h(8) of Directive 2003/87/EC.’"
Removed:Decision (EU) 2015/1814
Removed:Article 1 – paragraph 1 – point 4 a (new), Article 1a – paragraph 7 – sentence 2: (4a) In paragraph 7, the second sentence is replaced by the following: / ‘The volumes to be released from the reserve shall be evenly distributed over a period of three months, starting no later than 30 days after the date on which the conditions were met according to the publication in that regard in the Official Journal of the European Union pursuant to Article 30h(8) of Directive 2003/87/EC.’
Added:Article 1 a (new): Article 1a / In Article 3, the following subparagraph is added: / ‘Within four years from the start of the operation of emissions trading for buildings, road transport and additional sectors set out in Chapter IVa of Directive 2003/87/EC, the Commission shall carry out an impact assessment, including a distributional impact assessment, and an evaluation of the environmental, social and economic impact of the remaining allowances in the reserve under Article 1a, and determine the appropriateness of partially or entirely invalidating those allowances. That evaluation shall, where appropriate, be accompanied by a legislative proposal.’

Changed:Recital 3: (3) The analysis carried out of the expected functioning of the reserve, taking into account recent information, indicates that targeted amendments to some parameters would contribute to improving market predictability and to the stability of price movements in the early years of the new system. ThoseIn amendmentsorder shouldfor those amendments not to hinder the Union’s decarbonisation efforts.efforts, further action by the Member States is necessary. According to the European Central Bank, green investment in the Union remains below the levels required to meet the 2030 decarbonisation target, with particularly noticeable shortfalls during the COVID-19 pandemic. Closing this gap will require annual investments of between 2.7 % and 3.7 % of the Union’s 2023 GDP until the end of the decade, especially in the transport sector.target. Therefore, Member States need to remain vigilant against the risk of a green funding gap, particulary following the expiry of the Recovery and Resilience Facility, established by Regulation (EU) 2021/241 of the European Parliament and of the Council1a. / 1a Regulation (EU) 2021/241 of the European Parliament and of the Council of 12 February 2021 establishing the Recovery and Resilience Facility (OJ L 57, 18.2.2021, p. 17, ELI: http://data.europa.eu/eli/reg/2021/241/oj).gap.
