2011 deadlines specified in section 701(1), 701(2) or 
706(a) would substantially reduce compliance costs, the 
Administrator may extend, by rule, any of the compliance 
deadlines for emissions reductions that fall in 2009, 2010, 
or 2011 by one or two additional years. If the Adminis-
trator promulgates such an extension, the same extension 
may also apply to the deadline for allowance distribution 
specified in section 704(d)(1)(B)(ii). Any such extension 
shall not affect the 2020 cap on emissions specified in sec-
tion 701(2). 
‘‘(j) DEFINITION.—In this section, the term ‘covered 
entity’ means an entity covered by the cap under sub-
section (a)(1). 
‘‘SEC. 705. ADDITIONAL AUTHORITY TO REGULATE GREEN-
HOUSE GAS EMISSIONS. 
‘‘(a) ADDITIONAL REGULATIONS.—The regulations 
promulgated under section 703(a) may include additional 
regulations to reduce emissions of greenhouse gases from 
any source or sector, irrespective of whether the source 
or sector is described in section 704(b)(1). Regulations 
under this section may include emissions performance 
standards, efficiency performance standards, best manage-
ment practices, technology-based requirements, and other 
forms of requirements.

istrator’s authority to regulate greenhouse gas emissions 
pursuant to other provisions of law in effect on the date 
of the enactment of the Safe Climate Act of 2007. 
‘‘SEC. 706. GREENHOUSE GAS EMISSIONS STANDARDS FOR 
MOTOR VEHICLES. 
‘‘(a) IN GENERAL.—The regulations promulgated 
under section 703(a) shall include regulations under sec-
tion 202 setting standards for greenhouse gas emissions 
from motor vehicles. These standards shall reduce such 
emissions at least as quickly and at least as much (on an 
average vehicle basis) as the standards adopted by the 
California Air Resources Board at its September 23–24, 
2004 hearing (California Code of Regulations, title 13, 
sec. 1961.1). 
‘‘(b) REVISION OF STANDARDS.—Not later than Jan-
uary 1, 2014, and every 5 years thereafter, the Adminis-
trator shall promulgate regulations revising such stand-
ards to further reduce greenhouse gas emissions from 
motor vehicles, taking into account the reductions needed 
to achieve the emission reduction targets promulgated 
pursuant to section 701, as well as the technological feasi-
bility 
of 
achieving 
tighter 
standards 
of 
various 
stringencies.

CARBON
DIOXIDE
EQUIVALENT.—The 
term ‘carbon dioxide equivalent’ means the quantity

count the global warming potentials published by the 
Intergovernmental Panel on Climate Change. 
‘‘(2) GREENHOUSE GAS.—The term ‘greenhouse 
gas’ means— 
‘‘(A) carbon dioxide; 
‘‘(B) methane; 
‘‘(C) nitrous oxide; 
‘‘(D) hydrofluorocarbons; 
‘‘(E) perfluorocarbons; 
‘‘(F) sulfur hexafluoride; or 
‘‘(G) any other anthropogenically-emitted 
gas that is determined by the Administrator, 
after notice and comment, to contribute to glob-
al warming to a non-negligible degree.
