Science Based Targets

When you select Absolute Contraction as the target setting in Emissions Reduction Target, the system calculates the targets from base year to target year.

Fields

• Emissions Reduction Target (EmssnReductionTarget)

  • Target Setting Method (TargetSettingMethod)
  • Target Year Emissions (TargetYearEmissions)
  • Target Year (TargetYear)
  • Target Emissions Change Percentage (TargetEmssnChangePercentage)
  • Category (Category)
  • Target Setting Method (TargetSettingMethod)
  • Absolute Contraction Percentage (AbsoluteContractionPercentage)
  • Custom Absolute Contraction Percentage (CustomAbsoluteContractionPct)
  • Base Year Emissions (BaseYearEmissions)
  • Base Year (BaseYear)

• Annual Emissions Reduction Target (AnnualEmssnRdctnTarget)

  • Target Emissions (tC02e) (TargetEmissions)
  • Target Year (TargetYear)
  • Emissions Reduction Percentage (EmissionsReductionPercentage)
• Emissions Reduction Commitment (EmssnRdctnCommitment)
  • Commitment Type (CommitmentType)

Calculations

• EmssnReductionTarget.Target Year Emissions

  EmssnReductionTarget.Target Year Emissions = AnnualEmssnRdctnTarget.Target Emissions (tC02e) where AnnualEmssnRdctnTarget.Target Year = EmssnReductionTarget.Target Year

• EmssnReductionTarget.Target Emissions Change Percentage

  EmssnReductionTarget.Target Emissions Change Percentage = AnnualEmssnRdctnTarget.Emissions Reduction Percentage where AnnualEmssnRdctnTarget.Target Year = EmssnReductionTarget.Target Year

• AnnualEmssnRdctnTarget.Target Emissions (tC02e)

  Conditions

  • If EmssnReductionTarget.Category = "Science Based" and EmssnReductionTarget.Target Setting Method = "Absolute Contraction" and EmssnRdctnCommitment.Commitment Type = "1.5° Celsius"

    Then EmssnReductionTarget.Absolute Contraction Percentage = 4.2%

  • If EmssnReductionTarget.Category = "Science Based" and EmssnReductionTarget.Target Setting Method = "Absolute Contraction" and EmssnRdctnCommitment.Commitment Type = "2° Celsius" or "Well Below 2° Celsius"

    Then EmssnReductionTarget.Absolute Contraction Percentage = 2.5%

  • If EmssnReductionTarget.Target Setting Method = "Absolute Contraction" and EmssnReductionTarget.Absolute Contraction Percentage="Custom"

    Then EmssnReductionTarget.Absolute Contraction Percentage = EmssnReductionTarget.Custom Absolute Contraction Percentage

  • If EmssnReductionTarget.Target Setting Method = "Absolute Contraction", click Save to create Annual Emission Reduction Target records for each year from base year to target year and AnnualEmssnRdctnTarget.Target Emissions and AnnualEmssnRdctnTarget.Emissions Reduction Percentage for the target year are added in EmssnReductionTarget.

  If EmssnReductionTarget.Absolute Contraction Percentage = 4.2%, then Percent = 0.042

  If EmssnReductionTarget.Absolute Contraction Percentage = 2.5%, then Percent = 0.025

  If EmssnReductionTarget.Absolute Contraction Percentage = Custom, then Percent = (EmssnReductionTarget.Custom Absolute Contraction Percentage / 100)

  If Var A = AnnualEmssnRdctnTarget.Target Emissions (tC02e) for base year + 1 = EmssnReductionTarget.Base Year Emissions - (Percent * EmssnReductionTarget.Base Year Emissions)

  Var B = AnnualEmssnRdctnTarget.Target Emissions (tC02e) for base year + 2 = A - (Percent * A)

  The AnnualEmssnRdctnTarget.Target Emissions (tC02e) for all years from base year + 1 to AnnualEmssnRdctnTarget.Target Year are calculated.

  For example, if EmssnReductionTarget.Absolute Contraction Percentage = 4.2%, EmssnReductionTarget.Base Year = 2021, and AnnualEmssnRdctnTarget.Target Year = 2030, then here's how the AnnualEmssnRdctnTarget.Target Emissions are calculated:

  Table 1. Calculate AnnualEmssnRdctnTarget.Target Emissions (tC02e)

  Target Emissions (tC02e)	2020	2021	2022	2023	2024	2025	2026	2027	2028	2029	2030
  	1455385	1394259	1335700	1279601	1225857	1174371	1125048	1077796	1032528	989162	947617

• AnnualEmssnRdctnTarget.Emissions Reduction Percentage

  If var X = EmssnReductionTarget.Base Year Emissions

  then AnnualEmssnRdctnTarget.Emissions Reduction Percentage for base year + 1 = (Base Emissions in Base Year + 1 - X) / X

  Emissions Reduction Percentage for base year + 2 = (Base Emissions in base year + 2 - X) / X

  The AnnualEmssnRdctnTarget.Emissions Reduction Percentage for all years from base year + 1 to AnnualEmssnRdctnTarget.Target Year are calculated.

  For example, if EmssnReductionTarget.Absolute Contraction Percentage = 4.2%, EmssnReductionTarget.Base Year = 2021, and AnnualEmssnRdctnTarget.Target Year = 2030, then here's how the AnnualEmssnRdctnTarget.Emissions Reduction Percentage are calculated:
