The ETS does largely what it is supposed to do
Credibility is key
Do not start out in a second best-world
More analysis is needed to convince MS that they gain from a “first-best + redistribution” world

• Cap-and-trade incentivizes reductions with highest marginal abatement cost -> arguably more efficient than command-and-control
Zachmann, Abrell, Faye (2011)
But, ETS prices lower than expected

• The tighter cap in Phase II was effective since emissions decrease
• Under allocated companies in allowances for 2005 reduced their emissions the most
Zachmann, Abrell, Faye (2011)
Profit Margin 2004-2005 2004-2008
Impact of EU ETS -0.53 -0.51 *
Under allocated firms (AF<1)
Impact of EU ETS -0.22 -1.95 *
Over allocated firms (AF>1)
Impact of EU ETS 2.14* 2.32 *
But, Huge Windfall Profits
Overallocated firms have benefited significantly from the EU ETS in terms of profitability
Underallocated Firms did lose
Overall effect surprisingly slightly negative

5. Conclusion
Details, Details, Details …
There are a number of details that determine the performance of the EU ETS– Cap
– Initial allocation
– Coverage
– Dealing with leakage
– Locking in prices
– …
All of them are disputed
Detail 1 – Cap
Present– ~2 bn allowances
– -1.74 %
Future– Keep the path and
– Change the path now (e.g., 2020, 30%)
– Change the path in the future (e.g., 2030, 40%)
Detail 3 – Coverage
Widen: Inclusion of more sectors in the ETS
Deepen: strengthen the long-term price signal in the ETS
Enlarge: link to foreign systems
Detail 4 – Leakage
Indirect leakage cannot be tackled
Proposals for direct leakage: – Free allowances
– Border adjustment taxes (imports or imports+exports)
– Carbon consumption tax
– Allowance based system
Risks:– Trade wars (see aviation)
– Industrial policy
– Overly complex mechanisms (calculating life-cycle emission ?)
Detail 5 – Fixing prices
Different price targets
Floor price, price Collar, price Ceiling
€0-€100
Fixed or moving limit
Methods
Taxes
Managing the annual or period cap

Distributive Effects of European Climate Policy
The three main policies (RES, ETS, EE) affect member states differently

ETS: Central Europe has the highest potential for reducing emissions but is also most vulnerable

RES: Differing Support levels

Conclusion
The big horse-trading:
Burden sharing
Effort sharing
Initial allocation
…
Þ There are a lot of pretty un-distorting redistribution schemes
Þ Do not start out in a second best-world
Þ More analysis is needed to convince MS that they gain from a “first-best + redistribution” world
Example: De-risking low-carbon investments
Public bank auctions put options to investors
Investor will choose a hedging strategy
Investor get‘s payoff if carbon price is too low
ETS exposure on the balance sheet of public banks increases credibility of the ETS for all mkt participants
