New York State Department of Environmental Conservation Issues State-Wide Guidance Using the IWG SCC

  • Application

    For use by state agencies, in particular for "describing the global value of policies, programs, or projects or for estimating global damages in an assessment of benefits and costs."1

  • Date

    November 2020
  • Details

    The Climate Leadership and Community Protection Act ("CLCPA") directs the the New York State Department of Environmental Conservation ("DEC") to establish a value of carbon for use by state agencies.2

    On October 28, 2020, DEC published its draft guidance, Establishing a Value for Carbon: Guidelines for Use by State Agencies. The Department specifically recommends "the use of the U.S. Interagency Working Group’s (IWG) damages-based value of carbon, also referred to as the social cost of carbon dioxide, methane, and nitrous oxide."3  

  • SCC Value(s)

    DEC recommends that agencies use a range of discount rates from 1% to 3% or a central value using a discount rate of 2% or 2.5%.  For year 2020 emissions, this means a value of carbon dioxide of $53-421 per ton, with a central value of $79-125 per ton; a value of methane of $1,527-6,578 per ton, with a central value of $2,036-2,782 per ton; and a value of nitrous oxide of $19,084-140,766 per ton, with a central value of $27,989-44,727 per ton.4
