One simple idea unites almost all environmental economists.
It is the importance of pricing external costs – the social and environmental
damage caused by greenhouse gas emissions – into markets so that users and
consumers are forced to recognise and pay for these costs at the point of use,
and not allowed to fall instead on the public at large or on future
generations.
Unfortunately a simple implementation of such an approach
runs head first into some major political realities. The first is that the
level of pricing applied to fossil fuels that would be necessary to reduce
emissions quickly or substantially is high, and would be a major economic shock
both to many industries and consumers. The industries affected tend to be
extremely vocal. The second is the observation that any resulting price increases
are most likely to have a disproportionate
impact on poorer consumers.
Just to illustrate the point the European Union’s emissions trading
scheme (the ETS) has over long periods produced carbon prices of significantly
less than €15 per tonne, in a period when the price
at which key technology transformations occur has appeared to be much higher,
around €70 or more. Even more significantly it is now widely recognised that
the world is so far from reaching safe climate targets that it will have to
contemplate large scale sequestration of CO2, ie extraction from the
atmosphere, with much higher costs, probably at least €200 per tonne (best available
current technology puts this figure at around €600 per tonne).
Failures of the ETS reflect many factors, including industry
lobbying and the post crisis recession, but they certainly include weak
political will in relation to higher carbon prices.
Carbon Fee and
Dividend
Citizens’ Climate Lobby[1]
has proposed a carbon fee and dividend approach, in which the whole of of the revenue
from a “carbon fee” is returned directly to households as a monthly dividend.
The idea is that the majority of households will receive more in
dividend than they pay in increased energy costs. This feature protects family
budgets, frees households to make independent choices about their energy usage.
The higher fuel prices spur innovation in low-carbon products.
The scheme would include border adjustments[2] to
protect UK businesses, levying import fees on products imported from
countries without a price on carbon, along with rebates to UK industries
exporting to those countries. This would discourage businesses from relocating
where they can emit more CO2 and incentivise other countries to adopt similar
carbon pricing policies.
In fact this idea is part of a family of similar ideas aimed
at shifting the burden of taxation towards “green taxes” which seek to redress
existing market failures that comprehensively fail to address environmental
problems. The counter part to these socially beneficial taxes is a reduction in
other forms of taxation, and related concepts include “revenue neutral carbon
taxation” and the notion of a carbon “wealth fund”, promoted in an
earlier blog on this site by Adam Whitmore.
The case for action
I believe there will be numerous points of detail to get
right, whatever new approach is adopted, and I have a few concerns on
specifics.
·
Border adjustment taxes look fine in principle,
but the administrative detail in their application looks formidable, and they
would still have to comply with international rules on trade.
·
CCL propose a gradual increase in tax on carbon,
starting from quite low numbers. As discussed in another page on this site, the
stark message of the science is that the highest cost attaches to early
emissions, since they are both cumulative and bring forward climate milestones.
·
Getting both the macroeconomics and the
redistributive consequences right will be challenging, both technically and
politically.
·
The idea of a wealth fund, as opposed to
immediate revenue neutrality, may be the preferable route.
Despite these concerns I am more and more convinced[3]
that more effective action on carbon pricing is essential, and that its
combination with a redistributive agenda in domestic politics is probably the
best available way to break the current logjams on climate policy.
