Parameters:

Name Type Description Default
cumulative_co2_emissions Series

Cumulative CO2 emissions from aviation over time [GtCO2].

 required
gross_carbon_budget_2050 float

Gross carbon budget allocated to aviation over 2020-2050 [GtCO2].

 required

Returns:

Name Type Description
carbon_budget_consumed_share float

Share of carbon budget consumed by aviation up to 2050 (%).
