Because the implementation of some technologies reduces emissions for multiple years, Natural Gas STAR allows certain activities to count
towards a company’s emission reductions beyond the initial year of implementation. Natural Gas STAR designates the maximum length of time
that these reductions may accrue as “sunset dates.” The Appendix lists these sunset dates. Companies can report the corresponding methane
emission reductions each year up to the allowable sunset date. Or, companies may wish to report reductions only once for the implementation
year, and have EPA automatically apply the sunset date and count those emissions for the allowable number of years.
In addition to reporting methane emissions reductions, you are welcome to include other information about your company’s participation in
Natural Gas STAR in the “Additional Program Accomplishments” section of this form. The Natural Gas STAR Program will use any information
entered in this section to recognize the efforts and accomplishments of outstanding partners.
