Characteristics

Brighter Planet is performing this calculation based on the following characteristics of this pet as provided in the request:

Characteristic Input Interpretation

Calculation

This calculation uses version ef8bb2e of Brighter Planet's pet carbon model.

Calculations are performed adaptively, so methodology will vary depending on pet characteristics. Impact values, listed below, are based on a number of input factors, which in turn are based on others, and so forth. In each case, the methodology used in the calculation is specified, and, wherever possible, the source code of the method is displayed.

  1. Carbon

    Conclusion: 755.3 kg

    Method: from diet size.

    (((active_subtimeframe.days * diet_size) * diet_emission_intensity) + (ANNUAL_VETERINARY_EMISSION * (active_subtimeframe / timeframe.year)))

  2. Diet emission intensity

    Conclusion: 6.274006446051712e-07

    Method: default.

    Species.weighted_average(:diet_emission_intensity, :weighted_by => :population)

  3. Diet size

    Conclusion: 3272083.4430364543

    Method: from weight.

    ((weight * marginal_dietary_requirement) + fixed_dietary_requirement)

  4. Marginal dietary requirement

    Conclusion: 118093.0239792151

    Method: default.

    Species.marginal_dietary_requirement_fallback

  5. Fixed dietary requirement

    Conclusion: 0.0

    Method: default.

    0.0

  6. Weight

    Conclusion: 27.707677666145255 kg

    Method: default.

    Species.weighted_average(:weight, :weighted_by => :population)

  7. Active subtimeframe

    Conclusion: 2012-01-01/2013-01-01

    Method: from acquisition and retirement.

    Timeframe.constrained_new(acquisition.to_date, retirement.to_date, timeframe)

  8. Acquisition

    Conclusion: 2012-01-01

    Method: from retirement.

    [timeframe.from, retirement].compact.min

  9. Retirement

    Conclusion: 2013-01-01

    Method: from acquisition.

    [timeframe.to, acquisition].compact.max
