The overall volume of greenhouse gases that can be emitted by the power plants, factories and other fixed installations covered by the EU emissions trading system (EU ETS) is limited by a 'cap' on the number of emission allowances. The EU ETS cap for the aviation sector has been separately calculated. Within the overall Europe-wide cap, companies receive or buy emission allowances which they can trade as needed.
Each allowance gives the holder the right to emit
Allowances are allocated and auctioned specifically to aircraft operators. Airlines can use either aviation or general EU emissions allowances for compliance; however fixed installations can only surrender aviation allowances for their emissions from 2021 onwards.
Since the beginning of phase 3 of the EU ETS (2013-20), an EU-wide cap on emissions is set centrally.
The cap for 2013 from fixed installations was set at 2,084,301,856 allowances. During phase 3, this cap decreases each year by a linear reduction factor of 1.74% of the average total quantity of allowances issued annually in 2008-2012. This amounts to a reduction of 38,264,246 allowances each year.
The linear reduction factor was set in line with the EU-wide climate action targets for 2020 – the overall 20% emissions reduction target and the EU ETS sector-specific 21% emissions reduction target relative to 2005.
In phase 4 (2021-2030), the cap on emissions will be subject to an annual linear reduction factor of 2.2% in line with the 2030 targets – the overall -40% emissions reduction target and the EU ETS specific -43% emissions reduction target relative to 2005. The increased reduction factor of -2.2%, results in an annual reduction of 48,380,081 emission allowances, in the period 2021-30.
Around 38 million allowances have been issued to the aviation sector annually since 2013, following a reduction in scope to apply to flights within the European Economic Area. This is considerably below the actual verified CO2 emissions from such flights, which have increased from 53.5 million tonnes CO2 in 2013 to 64.2 million tonnes in 2017. From 2021 onwards, the same linear reduction factor that applies to stationary installations, -2.2% annually, will apply to these allocations.
The EU ETS cap is the total amount of emission allowances to be issued for a given year under the EU Emissions Trading System (EU ETS). Since each allowance represents the right to emit one tonne of CO2 - or an amount of another greenhouse gas giving the same contribution to global warming as one tonne of CO2 - the total number of allowances, i.e. the “cap”, determines the maximum amount of emissions possible under the EU ETS.
In July 2010, the Commission adopted a decision that determined the cap for 2013 based on the current scope of the EU ETS, ie the installations covered in the 2008-2012 period. The second decision, adopted today, takes into account the extended scope of the EU ETS as from 2013.
The EU ETS covers installations performing specific activities. Since its launch in 2005 the system has covered, above certain capacity thresholds, power stations and other combustion plants, oil refineries, coke ovens, iron and steel plants and installations producing cement, glass, lime, bricks, ceramics, pulp, paper and board. As for greenhouse gases, it currently covers only carbon dioxide emissions, with the exception of the Netherlands and Austria, which have opted to include emissions from nitrous oxide ( N2O) emissions from some specific installations.
As from 2013, the scope of the ETS will be extended to include other sectors and greenhouse gases. Inter alia, more CO2 emissions from installations producing bulk organic chemicals, hydrogen, ammonia and aluminium will be included, as will N2O emissions from the production of nitric, adipic and glyocalic acid production and perfluorocarbons from the aluminium sector. Installations performing activities which result in these emissions will be included in the EU ETS as from 2013.
The cap for the year 2013 has been determined at 2,084,301,856 allowances..
This figure is based on the national allocation plans of Member States for the period from 2008 to 2012 but also takes into account the extended scope of the EU ETS as from 2013 as well as installations 'opted in' to the system by Member States from 2008. It is composed of the following elements:
From this quantity, the quantity of allowances that represent the effect of installations opted out from the EU ETS would need to be deducted. The corresponding amount deducted was 4,751,898.
The initial cap published by the Commission in October 2010 was 2,039,152,882 allowances.
Since the cap for 2013 is calculated from the midpoint of the period 2008 to 2012, i.e. 2010, the linear reduction factor of 1.74% (in absolute figures: 38,264,246 allowances) had to be applied three times (in 2011, 2012, 2013), in order to arrive at the total absolute Union-wide quantity of allowances (cap) for 2013, i.e. 2,084,301,856 allowances.
The figure representing the quantity of allowances to be issued in accordance with the National Allocation Plans has been established applying the same methodology as used in the Commission's July decision. Basically, it means that the total quantity actually available in the period from 2008 to 2012 has been added up and divided by five. However, as set out in this Decision, additional information has been taken into account, mainly related to new entrants and closed installations. As a consequence, the corresponding figures are now slightly higher than those indicated in the July decision.
The figure representing the effect of the opt-ins has been established in a similar manner as the figure above, i.e. the relevant annual average for 2010 has been calculated by adding up the total amount of allowances opted in for the period from 2008 to 2012 and dividing it by the relevant number of years.
In order to determine the quantity of allowances by which the cap has to be adjusted in order to reflect the extended scope of the EU ETS as from 2013, Member States had to ensure that operators of installations carrying out activities that will be included in the EU ETS only from 2013 onwards submitted duly substantiated and independently verified emissions data..
Member States had to notify duly substantiated data to the Commission by 30 June 2010. The data notified to the Commission cover different years of verified emissions and are therefore not easily comparable. The Commission had to establish an approach with a view to providing a level playing field for all installations included in the EU ETS as from 2013. To this end and for the purpose of establishing the Union-wide quantity of allowances for 2013, the Commission assumed that installations to be included as of 2013 had undertaken the same level of emission reduction efforts as those installations already included before 2013. For this reason, the linear reduction factor of 1.74% was applied to the annual average figure from the midpoint of the period covered by the verified emission data notified by each Member State. The outcome would represent the level of emissions in 2010, had the installations concerned already been included in the EU ETS.
|Member State A|
|Period covered by verified emission data||2005||2006||2007|
|Verified emission data||1250||1230||1120|
|Annual average verified emissions of reported period||(1250 + 1230 + 1120) / 3 = 1200|
|Adjusted average verified emissions of reported period (figure to be taken into account for cap 2013)||1200 – (1200 x 0,0174 x (2010 – 2006)) = 1116|
Member States have collected the necessary data from installations performing activities which will be included in the EU ETS as from 2013. These data had to be independently verified before the operators of the relevant installations submitted them to the competent authorities of their respective Member State (for which the deadline was 30 April 2010). Where Member States found these data duly substantiated, they could notify them to the Commission by 30 June 2010. On the basis of these notifications, the Commission took into account the extended scope of the EU ETS as from 2013.
In practice and to a large extent yes. However, marginal fine-tuning is likely to be needed over time, for the following potential reasons:
For these reasons, final figures for the 2013 cap may thus not be available before 2013. However, in order to keep the public informed, the Commission will update the figures in 2011 or later. These updates should lead only to marginal changes in the overall quantity of allowances available from 2013 onwards.
The cap will decrease each year by 1.74% of the average annual total quantity of allowances issued by the Member States in 2008-2012. In absolute terms this means the number of allowances will be reduced annually by 37,435,387. This annual reduction will continue beyond 2020 but may be subject to revision not later than 2025.
If the EU decided to move to a 30% reduction target the cap would need to be revised. Today's decision reflects the 20% reduction target from 1990 levels as enshrined in current legislation. This translates into a 21% cut in emissions from installations in the EU ETS by 2020 compared with 2005 levels.
The cap for the aviation sector is determined separately, and is around 38 million allowances annually between 2013 and 2020. The actual emissions from aviation activities within the European Economic Area are considerably higher, around 64 million tonnes in 2017, and airlines purchase allowances from the overall EU ETS, as specified in the EU Directive including aviation in the EU ETS
