**body:**

(a) Clean heat targets shall align with the statewide greenhouse gas emission
reduction goals set forth in § 25-7-102(2)(g), C.R.S., and shall be consistent with
§ 40-3.2-108, C.R.S., et seq.
(b) Baseline emissions, system-wide emissions, and reductions in emissions shall
be calculated in accordance with rules 4525 through 4528.
(c) Baseline.
(I) The utility shall calculate a baseline level of emissions for calendar year
2015, calculated in accordance with rule 4527.
(II) The utility shall exclude the emissions of customers, and to the extent
practicable identify those customers and their associated load, that report
their own greenhouse gas emissions to the United States Environmental
Protection Agency under applicable federal law.
(d) Targets.
(I) The following clean heat targets apply for a gas distribution utility:
(A) four percent reduction in greenhouse gas emissions in calendar
year 2025 as compared to a 2015 baseline, of which not more than
one percent (one-fourth of the emission reductions required to meet
the 2025 target) can be from recovered methane;

(B) 22 percent reduction in greenhouse gas emissions in calendar year
2030 as compared to a 2015 baseline, of which not more than five
percent (five-twenty seconds of the emission reductions required to
meet the 2030 target) can be from recovered methane;
(C) 41 percent reduction in greenhouse gas emissions in calendar year
2035 as compared to a 2015 baseline; and
(D) a jurisdictional gas utility’s clean heat plan may exceed the
recovered methane caps set forth above in subparagraphs (A) and
(B) if the Commission finds that the utility otherwise could not cost-
effectively meet the clean heat targets and that exceeding the
recovered methane caps is in the public interest.
(II) No later than December 1, 2032, the Commission, in consultation with the
Air Pollution Control Division, shall determine the mass-based clean heat
targets for years 2040, 2045, and 2050 using the 2015 baseline pursuant
to § 40-3.2-108(11), C.R.S.
(e) For clean heat targets beginning in year 2035, the maximum amount, if any, of
each target reduction in greenhouse gas emissions that may be from recovered
methane shall be determined by the Commission if such maximum levels
promote investment in Colorado communities, reduce greenhouse gas
emissions, are cost-effective, and are in the public interest.
