2Outline
- CO2 emission reduction strategy
- Failure of voluntary commitments
- Effectiveness of price mechanism
- Separate environmental externalities from
technology policy (learning externalities) - The European Emission Trading Scheme
- Impact of updating (conditional allowance
allocation) - Impact of free allowance allocation to new
entrants - Border tax adjustment to allow auction of
allowances and higher CO2 prices
3European strategy to reduce CO2 emissions
- European Climate Change Program 2000
- Bonn/Marrakech/EU required delivery of Kyoto
targets - After criticising US, policymakers had to show
action - Failure of voluntary commitments in 1990
4Instrument I Industry self regulation Example
Germany
- CO2 2000 industry promised 20 Mtones reductions
by 2005 so far only increase - Industry option to avoid renewables legislation
by achieving quota (1990) - Education quotas at firm level
- Price stability with Euro introduction
- Self-regulation of energy sector
- Cigarette advertising/ product labelling

to improve energy efficiency 87 of CCLA firms
had taken action or were planning to do so

CO2 pricing is unlikely to unlock new renewable
technologies. But reduces costs of strategic
deployment programs.
11Technology cost reductions with deployment
12Technology Policy separate from CO2 trading
- Renewable contribution
- Quotas EU commitment 13.9 (97) to 22 (10)
- Implemented using national policy
- So far only feed in delivered (DK, D, ES)
- Some renewable RDD programs
- Transport of energy / transport fuel
- H2, 2 bil.Euro in 6th framework/ in US 1.7 bil.
- Carbon Sequestration/nuclear perceived as
marginal - Public concerns about leakage

13Emission Trading Scheme and Kyoto
- ETS independent of Kyoto entering into force
- ETS set up to comply with Kyoto targets
- Russian signature (seems quite secure)
- Would start Kyoto
- Will Russia/Ukraine oversupply?
- CO2 allowance trade only at state level
- Review if member state import more than 6 of
allowances. - Limit imports to keep carbon price up
- US participation would increase carbon price
14The ETS System A Four Level Approach
Cap defined by EU Burden Sharing
Different cap options (modeling, voluntary
agreements, distance to target)
Different cap options (Flat rate, sector specific
caps)
Different Allocation options. Most likely
common formula extra allocation
Ref Matthes, Oeko Institute
15Average cap and BAU emissions compared to Kyoto
commitment for 2006
Source ECOFYS, The BAU numbers are in most cases
indicated in the National Allocation Plan. If BAU
was not available in NAP, but needed to be
derived from other sources, this is indicated by
using an open circle, instead of a closed circle.
If it was not possible to derive a BAU, no circle
is given for that specific country.
16Issues about the NAPs
- Incentive for countries to allocate more rights
- Value of rights for national industry/auction
- Impact on EU emission price -gt cost of
inappropriate adjustment - Objective of Commission to implement mechanism on
time (January 2005)
17Allocation plans
- Political economy buy in of companies
- SO2/NOx In US lump sum to incumbents.
- CO2 higher value politicians equity concern
- Explicit updating
- NAPs defined till 2007, Kyoto till 2012
- Implicit updating regarding future allocation
- New Entrant provisions
- Regional competition or Coal support?

Scarcity value of capacity decreasing. To ensure
profitability of technology 1, dct/dµ gt 0
- Investment in both technologies is increased
(while scarcity value positive) - Allowance price and for dA/dctgt0 emissions
increase.

- Low emission technology is displaces by high
emission technology and total capacity increases. - Allowance price and emissions are increased.
33Impact of Allocation Rules on UK Wholesale Prices
Price reflects energy-weighted average wholesale
power price across UK assuming a CO2 price of
10/tonne. Source ICF Consulting, March 2004.
34Impact of competing countries not participating
- Concerns for competitiveness of EU industry
- Could particularly affect location decisions
- Hence provisions for allocation of allowances to
new entrants in NAPs (for 2005-2007) - Distortions of technology choice (Germany)
- Distortions of location choice (between
countries) - Long-term commitment reduces policy options
- How many reserves to retain for entrants?
- Updating provisions reduce effectiveness
35Requirement to implement stringent policy
- Emission trading only works if
- No updating allowance priceopportunity cost
- Minimise allocation to new entrants
- EU Energy intensive industry will lobby against
high CO2 prices if they are unilateral - US Energy intensive industry will increase lobby
against CO2 constraints if they can free ride - We need border tax adjustment
36Border Tax Adjustment for CO2 allowance costs
- Reimburse exporter for allowance costs
- Add import tax for avoided CO2 allowance costs
- Allows for internalisation of externalities
- Treatment similar to value added tax
- Other regions can apply it (e.g. Canada)
- But product not process based
- Focus on energy intensive component
- Small transaction costs
- Based on best available technology
- Simple monitoring / tariff setting
- WTO compatible
37Conclusion
- ETS in place and starting January 2005
- Covers emissions from large installations
- Technology policy separate (and needs to be)
- To get industry buy in Free allocation
- Politicians then required Updating
- New entrant allocation
- Result are likely
- Allowance prices look higher -gt dont be fooled!
- Distortions in investment decisions.
- Border tax adjustment could allow for higher CO2
price levels.
