A national climate policy in the USA?
• Obama Administration target in US INDC:
– Reduce overall US emissions 26-28% below 2005
level by 2025
– US-China joint announcement (2014); for an early
advocacy of this path, see Stewart & Wiener,
Reconstructing Climate Policy (2003)
• How to achieve this target?
– New law? In the meantime: under older Clean Air
Act (CAA), US Environmental Protection Agency
(EPA) regulations – section 111 “Clean Power
Plan” and more – following the US Supreme Court
decision in Massachusetts v. EPA (2007)
Massachusetts v. EPA (U.S. Supreme Court, 2007)
• Mass. et al. asked EPA to list GHGs under CAA 202 (mobile sources).
• EPA (in G.W. Bush administration) denied this petition, arguing:
– GHGs are not “air pollutants” under CAA. Too big an issue to be covered
under CAA without clear language (FDA v. Brown & Williamson doctrine).
– CAA is poorly suited to regulating GHGs.
– GHGs are a subject of international negotiations, foreign policy concerns.
• US Sup.Ct. held (5-4): GHGs are “air pollutants” under CAA 202.
– Dissent by Justice Scalia: “air” vs. “atmosphere” ?
– GHGs are presumably also covered under other sections of the CAA.
– EPA must confront “endangerment” finding for GHGs.
• It is unclear when EPA can decline to undertake an endangerment evaluation.
Can EPA set priorities among pollutants under CAA?
– EPA issued Endangerment Finding in December 2009 (Obama admin.).
Upheld in Coalition for Responsible Regulation v. EPA (DC Cir., June 2012).
• EPA’s authority reaffirmed in AEP v. Connecticut (US Sup.Ct. 2011).
– Held: tort/nuisance claims are displaced by EPA’s authority under CAA
U.S. Clean Air Act (CAA) Enacted 1970, amended 1977, 1990
Some key sections:
• 101 – Purpose
• 108 – Listing “criteria air pollutants”
• 109 – National Ambient Air Quality Standards (NAAQS)
• 110 – State Implementation Plans (SIPs)
• 111 – New Source Performance Standards (NSPS) – plus existing sources under 111(d)
• 112 – Hazardous Air Pollutants (HAPs) (air toxics)
• 202 – Mobile sources (automobiles, trucks) (also airplanes)
• 115 – International reciprocity
• 615 – Stratospheric Ozone
Major EPA rules on GHGs, so far
• GHG Reporting Rule (2009) (new legislation!)
• Mobile sources: fuel economy standard (2010)
– Under CAA. Hence application of “PSD”; Tailoring Rule
– Airplane emissions: EPA endangerment finding, June 2015
• Electric power – “electric generating units” (EGUs)
– President’s climate action plan, June 2013
– New sources: CAA 111(b) rule, proposed January 2014
– Existing sources: CAA 111(d) rule, “Clean Power
Plan,” proposed June 2014 (… final rule July 2015 ?)
• State plans due in 2016 (later if multi-state)
• EPA review of state plans …

EPA “Clean Power Plan” seeks to help achieve the US INDC target of 26-28% below its 2005 level by 2025 – by reducing the US electric power sector 30% below its 2005 level by 2030 (one of the policies included in the blue line labeled “Core Ambition”).
28%
2005 level
EPA “Clean Power Plan” is based on CAA §111 –
“New Source Performance Standards” (NSPS)
• §111(b) authorizes EPA to set emissions standards for new and modified pollution sources
– NSPS are set for each source category; within each category, standards may vary according to class, type, size of source
– NSPS are “performance standards” (not “design standards”); EPA does not mandate specific technology. An NSPS “reflects the degree of emission limitation achievable through the application of the best system of emissions reduction [BSER] which (taking into account the cost of achieving such reduction and the non-air quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated.”
• §111(d) authorizes EPA to regulate existing sources –
– if they would be covered by a 111(b) NSPS if they were new
– if they are not also being regulated under §109 or §112
EPA has proposed 2 rules for GHGs per§111
• New sources: In January 2014, EPA proposed a standard for GHGs
from new electric generating units (EGUs) under 111(b). BSER:
• For natural gas EGUs: emissions rate 1000 lbs/MWh, i.e.
about the same rate as recent new gas EGUs.
• For coal EGUs: 1100 lbs/MWh, lower than recent coal
“Well, one of the challenges that we have … is to explain the difference between
regulating under this section of the Clean Air Act and what Congress might do to
adopt a cap-and-trade program or a market-based solution. This is not that. This is
111(d), which looks at what can we do to get some best practices out there to reduce in
this particular sector, which is just the fossil fuel fired plants. …
“Building blocks, and it’s basically shifting to cleaner supplies and getting the waste
out of the system, whether it’s at the facility or more generally, and it’s pretty simple.
We looked at what other states have been able to do, what their progress is, how
they’ve been able to take advantage of it, what kind of pace that it takes to do these
things. And we took a moderate approach to each one [state], so that they’d have
flexibility to take whatever approach they wanted, relying more heavily on building
block two than one than three. And then we gave each state a goal, and that’s how we
articulated the overall reduction we would achieve.
“Now, there are many states that have wanted us to recognize actions that have
happened earlier. And we’re looking at that, and we’ll take those comments very
seriously, but the one caution I would sort of lay down at this point is it’s not going to
look like a cap-and-trade program. This is not about carbon offsets. This is not about
achieving a particular national target. It never was. It is about applying the Clean Air
Act in a way that’s going to be legally defensible, but still be aggressive in terms of
achieving the reductions.” (emphases added)
Carbon prices under the EPA 111(d) “Clean
Power Plan”
• EPA forecast of carbon prices in the year 2030
(under Proposed version of rule) ($/ton CO2e):
• State-by-state mode: range from $0 (in California) to
$101 (in West Virginia).
• Multi-state mode: range from $24.64 to $32.77.
• Narrower range of prices in multi-state mode implies
that promoting emissions trading markets across states
would be more cost-effective.

• Note: the Final Rule may differ (July 2015 ?).
Toward a US national carbon market via 111(d)?
1. EPA’s proposed rule invites multi-state plans – Trading could occur within several multi-state markets – like RGGI, and
California/Quebec/Ontario. And, they could link among each other.
– Like “clubs” at international level – exclusive benefits? Federal power.
2. Each state plan could allow national trading – without
expressly enacting it – by adopting key “common
elements” (Monast, Profeta, Tarr & Murray, NI PB, March 2015):
– the same unit of compliance as other states (e.g. mass-based)
– a common (or linked) tracking system
– recognizing reduction credits from other regulated sources
– other features not too different among states (e.g. price collar)
3. EPA could adopt a national “FIP” …
4. EPA could issue a Final rule that creates a market …
§ 111(d) and State Implementation Plans (SIPs)
• Under §111(d)(1), EPA must use a “procedure similar” to §110. (how “similar”?)
• Under §110, each state of the USA must:
– Submit a State Implementation Plan (SIP) to EPA that provides for “implementation, maintenance, and enforcement” of the National Ambient Air Quality Standard
(NAAQS) within that state. (But under §111, there are no NAAQS; instead, the SIPs must achieve the “standard of performance” per the BSER.)
– Adopt its SIP within 3 years after EPA promulgates NAAQS (or any revision)
– Adopt emission limitations and other control measures (to meet NAAQS or other standards)
– Adopt air quality monitoring and reporting systems
– Adopt enforcement mechanisms
– Adopt adequate provisions to prohibit interstate spillovers
Toward a US national market: from SIPs to
Federal Implementation Plans (FIPs)
• EPA could create a national market through a “FIP.”
– Voluntary opt-in (as in NOx trading 1998-2008; CAIR 2005)
– Mandatory (as in SO2 trading market 1990) ?
• §111(d)(2) authorizes EPA to adopt FIPs, if EPA
finds that a state plan is not “satisfactory.”
• Similarly,§110(c)(1) also provides that EPA shall promulgate
a FIP, within two years of:
– (a) EPA finding that the State has failed to submit a SIP, or did not
satisfy the minimum criteria in its SIP, or
– (b) EPA disapproving of a SIP submission, in whole or in part (unless
the State corrects the deficiency and EPA approves the revision).
• “FIP” is defined in§302(y) to include economic
incentives, allowance trading, and auctions.
(Could EPA use other CAA sections ?)
• Why use §111 vs. other sections of CAA ? – Can EPA use both 111 and 109 (or 112) ? No: 111(d)(1) precludes.
– What about using only 109 ? (NAAQS; cost.) Or 112 ? (MACT; cost.)
– EPA is already using 202 (mobile sources), GHG reporting rule, etc.
