Calculate a ration component's contribution to carbon dioxide (CO2) emissions from pesticide manufacture

Source: R/core_model_emissions_ration.R
calc_co2_ration_pesticides.Rd

Calculates the contribution of an individual feed component to carbon dioxide (CO2) emissions from pesticide manufacture in feed production, using feed-specific emission factors weighted by the component's share in the ration.

Usage

calc_co2_ration_pesticides(feed_ration_fraction, co2_feed_pesticides)

Arguments

feed_ration_fraction

Numeric. Proportion of a specific feed component in the total ration, expressed as its fraction of diet dry matter intake (fraction). Within each herd_id and cohort, proportions should sum to 1.

co2_feed_pesticides

Numeric. Carbon dioxide (CO2) emission factor of a feed component, representing CO2 emissions from pesticide manufacture in feed production, expressed per kilogram of dry matter intake (g CO2/kg DM).

Value

Numeric. Contribution of an individual feed component to the diet-level average carbon dioxide (CO2) emission factor from pesticide manufacture in feed production (g CO2/kg DM).

Details

The contribution is computed as:

$$diet\_co2\_feed\_pesticides = feed\_ration\_fraction \times co2\_feed\_pesticides$$
