Re: Climate policy options (Docket No. 04-CCAC-1 and Docket No. 04-IEP-1B)
To the Climate Change Advisory Committee:
I am encouraged that the last
meeting of the CCAC (
The Swedish program uses a
feebate-type regulatory instrument (aka. “Refunded Emission Payments”,
or REPs)
to motivate NOx emissions reduction from regulated power plants.
Emission
charges (“fees”) from plants with worse-than-average emissions
performance are
used to finance subsidies (“rebates”) for plants with
better-than-average
performance, creating a competitive market incentive to reduce
emissions. The
program is entirely incentive-based and is revenue-neutral. There is no
mandated emissions limit; instead the policy only mandates an
“emissions price”
that controls the level of fees and rebates. Nevertheless, the program
has motivated
power plant operators in
The NOx program was enacted in 1990 (and took effect in 1992), and had the objective of achieving 35% reduction in NOx emissions from large combustion plants by 1995. However, the industry responded by immediately reducing emissions, so that the 35% target was already achieved in 1993; and by 1995 the average emissions intensity of regulated plants had decreased by 60% relative to 1990 levels [2, 3]. Costs related to emissions abatement and monitoring turned out to be lower than expected, so smaller plants were incorporated in the program in 1996 and 1997; and NOx emissions from Swedish coal-fired power plants in 2000 have been estimated to be about four times less than typical U. S. emissions, on a per-MWh basis (or about nine times less if cogeneration heat is included in the comparison) [4]. The feebate-induced electricity cost increase has been estimated to be only $0.0004/kWh [5].
A primary advantage of feebates
over cap-and-trade is that their market incentives operate to minimize
emissions. Both approaches function to make emissions reduction
profitable
(from rebates or emissions trading), creating market incentives for
firms to
improve their emissions performance. In the case of feebates, a firm’s
improved
emissions performance will tend to increase the competitive pressure on
other
firms to also reduce their emissions. With cap-and-trade, however, the
better-performing firms’ actions enable other firms to increase
their emissions. (The sale of tradable emission credits
allows buyers to increase their emissions, offsetting any
market-incentivized
emissions reduction.) Thus, under a cap-and-trade system the market
incentives
provide no environmental benefit; they merely operate to minimize
regulatory
compliance costs.
An additional advantage of feebates relative to cap-and-trade is that they eliminate the possibility of emissions price spikes and volatility, because the feebate emissions price is directly regulated.
The California
Assembly just recently passed AB 1365, which establishes a near-term
objective
of achieving 7% reduction of GHG emissions in
AB 1493’s regulations are structured as a tradable performance standard (similar to cap-and-trade), but it is questionable whether this approach can actually achieve “maximum feasible and cost-effective reduction” of vehicular greenhouse gas emissions, as specified by the legislative mandate. CARB based the regulations on an extremely cost-conservative interpretation of the mandate. For example, “cost-effectiveness” was defined on the basis of a $1.74/gal fuel price (in 2004 dollars), which is assumed to apply over the 16-year life of a vehicle purchased after 2009. And hybrid vehicles, which represent one of the fastest growing automotive product segments, were considered to be “infeasible” for the purpose of determining the standard. This extreme cost-conservatism was necessary because although the legislative policy objective is to ensure cost-effectiveness, the standard-based regulations do not directly control costs – they control emission levels. Regulators have to predict what emission level will satisfy cost and feasibility constraints many years or decades in the future; and the emission caps must be set high enough to accommodate the uncertainty inherent in such projections. By contrast, there is no such predictive uncertainty with feebates because the emissions price, which limits feebate-induced abatement costs, is directly controlled by regulation.
The U. S. Acid Rain program also illustrates the effect of cost uncertainty in limiting regulatory effectiveness. The 1990 Clean Air Act Amendments were passed with the expectation that aggregate annual compliance costs for SO2 abatement would be as high as 5.9 billion dollars, but actual costs have turned out to be only about 1 billion dollars [7]. Had the costs been accurately predicted, SO2 caps could have been set at much more ambitious levels. Moreover, the costs of more stringent emission limits would certainly be justified by the benefits. Even ignoring the acid rain problem (which hasn’t yet been solved [8]), the human health benefits would far outweigh additional costs. For example, scrubbers can remove SO2 for under $300/ton, whereas the health benefits of SO2 abatement are estimated at $7,300/ton [9]. But even with such a dramatic return on investment, the Acid Rain program provides no incentive to further reduce emissions, because its cap-and-trade mechanism functions to minimize compliance costs, and not to minimize emissions.
Under a feebate-type
system such as
Presently,
climate-change initiatives at both the federal level and state level
are
focused almost exclusively on cap-and-trade-type approaches, but
feebate-type
policies represent a viable alternative that could overcome the
practical
limitations of cap-and-trade. (Environmental effectiveness is not the
only problem
with cap-and-trade – there are also issues related to initial allowance
allocation,
administrative complexity, and transaction costs.) The
Sincerely,
Kenneth C. Johnson
