Speaking at last Wednesday’s BIEE
Climate Policy Seminar Boris Lagadinov of Sandbag, the Brussels
and London based think-tank that addresses climate issues, gave an excellent summary
description of the development of the EU Emissions Trading Scheme (ETS), its
successes and shortcomings, and the prospects for remedying its defects in the
2020s, notably the status of Phase 4 (2021-2028) reforms and the overlap with
other policies. The presentation is available online (at least to BIEE members),
but the
fuller version of his analysis is also readily available on
the Sandbag website. It is an excellent exposition and I will not try to repeat
its detail, but rather aim to concentrate on some of the lessons and
implications discussed at the seminar and that we might draw from the ETS
experience.
The broad picture is well
known. The EU ETS has achieved compliance with its targets, largely as the
result of initially very undemanding targets (a result of extensive industry lobbying) combined with
recession induced falls in demand, but it has in the view of most commentators
wholly failed to produce carbon prices that are likely to have any significant
effect in reducing emissions, let alone incentivise the kind of transformative
change that is required across the energy sector or more broadly in the economy
or in lifestyle choices. In other words it provides no incentives for economy
wide decarbonisation.
Boris outlined the structural
reform measures associated with so-called “backloading” and the creation of a
Market Stability Reserve (MSR), but the scale of the surplus in the ETS stands
at about 3 billion tonnes in 2016 and Sandbag expect this to rise to about 4
billion tonnes by 2020. In broad terms this is about a full year’s EU emissions, but about two years for emissions falling within the scope of the scheme. The
reform proposals may be structurally sensible but the Sandbag analysis
indicates there is no real prospect that they will lead to a significant
increase in carbon prices any time soon.
In terms of fundamentals, the
EU ETS is a highly oversupplied system. Emissions have fallen much faster than
the “cap”, but it is quite clear that this has been entirely due to other
factors including the impact of so-called “overlapping policies” such as
national policies for the power sector, and for energy efficiency. It is very hard
to argue therefore that EU achievements in reducing emissions owe very much, if
anything, to its flagship policy, the ETS.
For economists, for whom adequate
pricing of the emissions externality is usually assumed to be one of the
simplest and most efficient and effective policies, this is a difficult pill to
swallow. In global terms the EU ETS was one of the earliest and is the world’s
largest attempt at using price and market mechanisms to control emissions. But
the outcome is that, in one of the largest players in the world economy, the
carbon price is having little impact and playing little or no part in policy.
And it now appears condemned to irrelevance for at least the next decade.
There is therefore a clear
contrast between the lofty ambitions of Paris, which the EU (including the UK)
have endorsed, and the reality of this core EU policy. And there are some clear
practical and philosophical lessons to learn, both in the EU and for other
regional schemes.
1 The
first is the importance of being clear about objectives. The required level of
long term global emissions reduction may be a clear target, but “region EU”
contributions, defined over relatively short time periods were always at best a
partial reflection of the real objective, which is to set in motion the massive
changes required in moving to a low carbon economy. It was and remains the case
that the long term objective requires very substantial transformative change,
and that the incentive of a significant carbon price should be playing a major
role in this. Failure of the EU ETS to deliver meaningful prices should therefore
have been interpreted as an early signal that the short and medium term targets
were far too slack and were certainly not consistent with EU ambitions to be a
global leader on climate.
2 Cap
and trade mechanisms are badly suited to the cumbersome and inflexible nature
of much of EU decision taking, demonstrated by the slow and inadequate progress
of MSR and related reforms. Cap and trade is intrinsically inflexible, given
the need to provide participants with some degree of confidence in the rules
and duration of the market. What is needed is policy instruments with the
ability to adjust to events, such as the recession, over reasonably short
timescales. Adaptive mechanisms permit a learning process. In this context
using price directly as a policy instrument (through a carbon tax) could have
been a much more effective policy instrument.
Unsurprisingly member states
with high levels of ambition have developed their own policies. These include
“floor prices” for carbon in order to support low carbon investments, but also
other direct interventions. It has been claimed that, paradoxically, these
so-called “overlapping policies” will in some instances give rise to implicit
“costs of carbon reduction” an order of magnitude higher than the actual carbon
price that would emerge even from a reformed ETS. Whatever the truth of this, the weakness of the
ETS means that we are likely to see more rather than fewer “overlapping
policies”.
These unilateral initiatives
have also led on to further disputes over policy. It can be argued that they
have undermined the carbon price and the ETS, and this finds its expression in
one conventional view that additional measures do not decrease cumulative
emissions, since they merely substitute for reductions that would otherwise
have occurred within the EU ETS “carbon bubble”. Sandbag analysis of this
argument, often described as the
waterbed effect, and the growing scale of ETS surpluses,
suggest that the waterbed myth is entirely fallacious, but that has not stopped
the myth giving rise to some damaging public policy consequences.
One example was the
objection on competition policy grounds to
proposed closure of five coal power plants in the Netherlands, as part of a national agreement to
move towards cleaner energy. Since this was to be done on the basis of an
agreement between producers, it hit problems of competition law. The companies
pleaded a “public interest” defence, namely reduction in CO2 emissions. However
the Dutch competition authority concluded that the agreement was in violation
of the cartel prohibition, arguing that the proposal would not reduce CO2
emissions, as claimed by the producers, since the redundant emission rights
would be sold on the open market and would therefore only be relocated. In
other words the “waterbed myth” was used
to obstruct an “overlapping” policy that would have resulted in a real and
immediate emissions reduction.
Inter
alia this shows that the impact of policy failures can go beyond simple failure
to achieve expectations, and can act as a barrier to other effective initiatives.
Regular readers of this blog will be aware of my opposition to the UK’s exit
from the EU, but the EU ETS has not proved to be a good example of successful
EU policy. It may still be sensible for the UK to participate post Brexit, in
the hope of its ultimate reform, but the UK will clearly need to continue its
own policy initiatives, as it has to date.
There are numerous
other issues for energy and decarbonisation policy that will spring from
Brexit, and that is the subject of the next Climate Policy Seminar, on 5th
April when Anthony Froggatt of Chatham House and Owen Bellamy of the Committee
on Climate Change are addressing the topic of “Brexit and Decarbonisation”
