3. Examining the Environmental Impact of EU-ETS
Introduction
Global warming is defined as an increase
in the Earth’s temperature and is triggered
by a rise in greenhouse gas emissions.
Most of the world’s emissions are attributed to mankind’s large scale use of fossil fuels
Burning fuels such as Coal, Natural Gas, & Oil Produces GHGs to the atmosphere in excess amount.
Leading to Climate Change manifestation – Increase harsh weather conditions, damaging storms, drought & other Global Warming Effects that cause increase economic & health problems for both man & animals

The greenhouse gas most commonly produced by our activities is carbon dioxide (CO2) & is responsible for 63% of man-made global warming. In 2008, CO2 emissions was responsible for 83% of GHGs Emissions in the EU–15 while Methane, Nitrous Oxide & Others recorded the balance 8%, 7% & 2% respectively
In 2008, Energy Sector is the highest emitter of GHGs with 28%. Followed by Transport 21% while Manufacturing, Agriculture and Industries have 13%, 10% and 7% respectively. Waste had 3% & Others 17%.

5. The EU Kyoto Targets
Kyoto Target: - The EU 15 member states has a Kyoto target to reduce their GHGs emissions by 8% in the period compared to its base year (1990) level.

The emission level in the 'base year' is the starting point for tracking progress of domestic emissions for EU-15. The base year is a calculated emission level from which emission reductions will take place (4,247,409). In practice, EU-15 base-year emissions can be considered close to 1990 emissions. The EU-27 does not have a Kyoto target.

6. EU – ETS : Mechanism and Operations
Emissions trading: - market based scheme for environmental improvement that allows parties to buy and sell permits for emissions or credits for reductions.
EU Emissions Trading Scheme: - The EU ETS was launched in 2005 and is the EU's climate change policy tool which helps industries to cut their CO2 emissions. The EU ETS is considered a central instrument for reaching the EU-15 target under the Kyoto Protocol.
Under the scheme, large emitters of CO2 are under an obligation to report their annual CO2 emission and to return an amount of emission allowance that is equivalent to their CO2 emission in that year. On the other hand, if an emitter is able to reduce its CO2 emissions then it is allowed to sell its emission credit and make a profit.
The EU ETS currently covers more than 10,000 installations with a net heat excess of 20 MW in the energy and industrial sectors which are collectively responsible for close to half of the EU's emissions of CO2 and 40% of its total greenhouse gas emissions.
The EU ETS aims to promote reductions of GHGs emissions in a cost-effective and economically efficient manner. The system operates through the allocation and trading of greenhouse gas emission allowances throughout the EU. One allowance represents one tonne of carbon dioxide equivalent.

7. EU - ETS Con’t
Mechanism: - The trading mechanism consists of matching emission buyers and sellers and then settling them by depositing a valid allowance in exchange for the agreed financial consideration. Just like the Stock Market, Companies and individuals can trade using brokers who are listed on the exchange.
Allocation: -
Free Allocation: An overall 'cap', is set by each Member State on the total amount of emissions allowed from the installations covered by the system. The allowances are then distributed by Member States to the installations in the system.
Auctioning: From 2013 emission allowances will be traded on a common auction platform, this will replace the free allocation of allowances generally followed in the first ( ) and second ( ) trading periods.
Pricing: - The actual carbon price is determined by market fundamentals – i.e too many allowances will result in a low carbon price and Vice Versa. For Instance, the average price of carbon was €22/tCO2 in the second half of 2008 but decreased to €13/tCO2 in the first half of 2009.

Phase1
( )
Sum of caps in each
country’s NAP based
on negotiating processes between Member State
governments and the
European Commission playing the role of “enforcer of scarcity”.
• CO2 only
• Power stations, ferrous
metals production,
cement, refineries, pulp
and paper, glass and
ceramics, and all combustion facilities >20MW and some opt-outs
• 42% of the European emission
At discretion of Members States but there is common characteristics:
• Auctioning is little used
• Strong reliance on recent historical emissions
• Expected shortage is
allocated to the power sector
• New entrant/closure provisions is made
Maximum 5%, (only 4 Member States used auctioning, mostly to cover
Administration costs)
CDM and JI allowed excluding
land use. Member States set caps on how many allowances can be imported
Phase 2
( )
country’s NAP aimed
at respecting Kyoto
targets and governed
by European Commission “anti-subsidy” rulings that
prevent allocation exceeding.
• CO2 with some N2O
emitting facilities opt-in
• Sectors: As of phase 1 without opt-outs. Some
combustion facilities
below 20 MW opt-in
• Air travelling is proposed for inclusion in 2011 or 2012.
• Possibly the maritime emissions related
At discretion of Members
States but there is common
characteristics:
• Strong reliance on recent
historical emissions
• New entrant/closure provisions benchmarked
Maximum 13.4%
(UK: 7%, Germany: 8.8%)
As of phase 1
Phase 3
( )
Cap calculated for Europe as a whole decreasing by
1.74%/yr from phase
2 average annual allowances starting in
2010 and aimed to
deliver 21% emission
reduction in 2020 compared to 2005
level and continue
thereafter at the same
rate with a review in 2025
• CO2, nitrous oxide for
acid production and
PFCs for aluminium
• Additional sectors:
non-ferrous metals, rock
wool, gypsum, various
chemicals, CCS related
emissions
• Combustion facilities
above 20MW with
harmonized rules and
derogations below 25MW
• Fully harmonised across
Member States
• No free allocation for power
generators
• 80% free allocation for other sectors in 2013 declining to zero in 2020 unless identified as exposed to carbon leakage
• 5% of the allocations set aside for new entrants
90% of the total allowances
Auctioned revenue is given
to countries in proportion to their verified 2005 emissions. The final 10% is redistributed according to GDP per capita.
• No international
agreement: CER/ERU banking from phase 2 under phase 2
qualifying rules
• International agreement: New
CER/ERU authorized limited
to gap half of the effort between the 20% European
objective of reduction and the 30% objective.

10. Methodology : The Input – Output Model
The input-output analysis was first devised by Wassily Leontief in 1936 to describe how industries are interrelated through producing and consuming intermediate industry outputs in an economy.
In matrix notation, the basic equation is 𝔁 = 𝜜𝔁 + 𝛄 Eq. (1) Where: 𝔁 = the total output required 𝛄 = the final demand/consumption 𝚨 = the matrix of technological coefficient, that represent the input required by another sector to produce its monetary output. Thus, 𝚨𝔁 = the n-vector of intermediate demand.
An environmental extension of the basic IO model can be obtained by introducing a q×m matrix B to show the amount of pollutants emitted to produce one unit output of each industry.
M = B(𝚰 − 𝚨)-1 𝛄 Eq. (3)
Where:
M = the multiplier matrix which shows the total direct and indirect pollutants intensity of each sector.
𝓍 is given by solving Eq. (1):
𝔁 =(𝚰 − 𝚨)-1 𝛄 Eq. (2)
Where:
Ι denotes the m×m matrix &
(𝚰 − 𝚨)-1 = the Leontief inverse
The variation of physical units of energy and CO2 equivalent in final demand is:
m = M 𝛄 Eq. (5)
m = total environmental impact produced by the change in the final demand.

11. Methodology & Data Preparation
The price rises resulting from carbon emission trading are given by:
P = 𝝁u Eq. (4)
Where:
u = the energy-related CO2 intensities
μ = the carbon price on CO2 emissions
P = n-vector with the derived carbon price rate on the goods produced.
Data Preparation
Following the information provided by Eurostat’s ESA 95 input-output tables, the study analyse 22 producing sectors and six types of fossil fuels (Lignite, Peat, Lignite Coke, Natural Gas, Liquid Fuels and Diesel Oil) in the EU-15 member countries.
Figures refer to the year 2005 input-output table and corresponding emission data available for all 15 countries.
Primary energy-use by input-output sector referring to 2005, used in the data base is derived from ESDS/IEA beyond 20/20 web data set (2010 Edition).
The ratio of CO2 emissions to fuel use by sector are easily obtained by dividing the amount of fossil fuel use by the carbon emission from each sector.

15. Conclusion
The study suggests a number of policy adjustments for future EU climate change policy.
Future policy actions should avoid focusing on the actual CO2 emitters but instead adopt strategies that help modify the behaviour of those responsible for CO2 emissions.
Governments must therefore reach their Kyoto targets through emission reductions from policies and measures addressing the sectors not covered by the EU ETS and/or through flexible mechanisms.
The results also signify the need to improve the overall efficiency of the EU energy system, and not only focus on the actual CO2 emitters.
