We stand at a crossroads on energy policy in the United States. Our dependence on oil is costing consumers at the pump, draining the economy, endangering our national security, and polluting the environment. For better or worse, the decisions our elected

Executive Summary
At the direction of their governors, representatives of nine
Northeast states (Connecticut, Delaware, Maine, Massachusetts, New
Hampshire, New Jersey, New York, Rhode Island and Vermont) are
currently working to develop a regional cap-and-trade system designed
to limit emissions of carbon dioxide (the leading global warming gas)
from power plants in the region. The process, known as the Regional
Greenhouse Gas Initiative (RGGI), holds the promise of significantly
reducing the Northeast’s contribution to global warming.
A
number of stakeholders in the RGGI process have suggested that the
region allow owners of power plants to purchase “offsets” (reductions
in global warming emissions made at other facilities outside the region
or at facilities other than the fossil fuel power plants regulated
under the program) to ease compliance with the program or to help
achieve further reductions. Supporters of this approach claim that
allowing the use of offsets will reduce the cost of global warming
emission reductions while achieving similar environmental benefits and
broadening the reach of the program to other sectors of the economy.
However,
allowing offsets to be used to comply with a regional power-sector
emission cap could undermine otherwise significant gains in reducing
carbon dioxide emissions from power generating facilities. There are
three main reasons for the Northeast to resist a liberal approach to
offsets in setting rules for the cap-and-trade program:
1. Offsets reduce the certainty of achieving real emission reductions.
•
Rules for the use of offsets typically require that offsets deliver
emission reductions that are real, surplus, permanent, quantifiable and
enforceable. Assuring that offsets meet these criteria is very
difficult. For example: - Emission reductions may
not be “real” if reductions claimed in one location are simply shifted
elsewhere. (For example, as a result of a manufacturer reducing
production in one location but increasing it in another location).
-
Emission reductions may not be “surplus” if the reductions would have
occurred anyway. (For example, through the planned replacement of aging
equipment with a more energy-efficient model.)
- Emission
reductions are not easily enforceable if they occur outside the region
or in a sector of the economy that is not vigorously regulated.
•
Assuring compliance with these criteria through aggressive monitoring
and verification efforts drives up the administrative costs of the
program. Failing to do so reduces the certainty of achieving
environmental benefits.
2. Offsets reduce the associated benefits of achieving emission reductions within the region.
•
Requiring that emission reductions be achieved at power plants within
the region (as opposed to through the purchase offsets from elsewhere)
would encourage the renovation, repowering or closure of some of the
region’s oldest, dirtiest and least-efficient power plants.
• In
2000, approximately half of all carbon dioxide emissions from power
plants in the RGGI region came from just 20 power plants. These plants
produced twice as much carbon dioxide per unit of power produced as the
regional average. They also emitted:
- 38 percent of the
region’s power-sector emissions of mercury—a neurological toxicant that
has triggered fish consumption advisories nationwide
- 64 percent of the region’s power-sector emissions of sulfur dioxide, which causes acid rain
- 47 percent of the region’s power-sector emissions of smog-forming nitrogen oxides
While
other air pollution control programs mandate reductions in emissions of
these pollutants, the renovation, repowering or retirement of these
plants could reduce the overall need for and thus cost of installing
emission controls.
• A strong regional carbon cap without
offsets could provide further momentum in the region’s efforts to
achieve a cleaner, more reliable electric system by making greater use
of renewable energy and improved energy efficiency. One recent study by
Synapse Energy Economics found that such an approach—if adopted
nationally—would reduce carbon dioxide emissions while generating $36
billion annually in savings by 2025.
3. Offsets will dull, not enhance, momentum for emission reductions in other sectors of the economy.
•
Supporters of offsets claim that allowing other sectors of the economy
to participate in the power-sector program will create the foundation
for future emission reduction efforts in those sectors. However,
cap-and-trade systems may not be the most appropriate means to reduce
emissions in some portions of the economy with large climate impacts
and could delay other policies that would be more effective—further
limiting the precedent-setting potential of an offset program. Indeed,
providing financial rewards to entities outside of the power sector
that reduce their greenhouse gas emissions could create a disincentive
for those entities to accept a mandatory emissions cap later on.
•
Achieving real, quantifiable emission reductions in the electric sector
in the Northeast would set a powerful example that such reductions are
achievable – and encourage the development of programs that produce
similar results in other regions and other sectors of the economy.
The
Northeast should tread carefully before allowing the use of offsets to
comply with a power-sector carbon dioxide emission cap. Specifically:
•
The Northeast governors and their staff involved in the RGGI process
should stick with their originally stated goals and principles by not
incorporating the use of offsets until after the core cap-and-trade
program is designed and the model rule is adopted. As the original
Action Plan for the process sets forth, offsets should be considered
simultaneously with expansion of the cap to other sources.
•
States should first determine the cap level they can achieve without
the use of offsets. Offsets should only be considered if the carbon
dioxide cap adopted through the RGGI process is strong—requiring
emission reductions of at least 10 percent below current levels by 2010
and 25 percent below current levels by 2020.
• Should offsets
eventually be included in a later phase of the program, the Northeast
should adopt a conservative approach, requiring that:
-
Offsets be generated only within states participating in the
cap-and-trade program. Offsets from outside RGGI will be difficult to
enforce and allowing them will reduce the incentive that other states
have to join the program. In addition, dollars paid by consumers in the
RGGI states should go towards emissions reductions and investments here
at home.
- Strong provisions be established to assure that offsets represent real, surplus emission reductions.
-
Nuclear power projects and other environmentally damaging technologies
not be eligible for offsets or otherwise obtain a market advantage for
being zero emitting in any cap-and-trade system.
- Offsets be
limited to no more than five percent of the total number of emission
allowances issued. This would allow for demonstration of the viability
of an offsets program while limiting the potential damage that a poorly
designed program could inflict.
- The benefits of offsets be
shared equally between those covered by the cap and the environment.
For example, a decision to allow 10,000 tons of offsets should be
paired with a reduction in the cap of 5,000 tons.
