Key messages
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

Conceptual Framework
First best policy adresses individual externalities with optimal solutions

representationin the table. However, the grading P, S, and N is not useful for policy failures as it isalways important to correct them should they be made.

• Cap-and-trade incentivizes reductions with highest marginal abatement cost -> arguably more efficient than command-and-control

• The tighter cap in Phase II was effective since emissions decrease
• Under allocated companies in allowances for 2005 reduced their emissions the most

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
![Page 16: The role of carbon pricing](https://reader036.vdocuments.site/reader036/viewer/2022062222/56816402550346895dd5a488/html5/thumbnails/16.jpg)
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 ?)

Conclusion
The big horse-trading: Burden sharing Effort sharing Initial allocation …Þ There are a lot of pretty un-distorting redistribution
schemesÞ Do not start out in a second best-worldÞ 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
