Bases: ITR.portfolio_aggregation.PortfolioAggregation

Lookup the companies in the given portfolio and determine whether they have a SBTi approved target.

Parameters:

  • config – A class defining the constants that are used throughout this class. This parameter is only required if you’d like to overwrite a constant. This can be done by extending the PortfolioCoverageTVPConfig class and overwriting one of the parameters.

  • cta_file_path – Optional path to a user-provided CTA file. If set, the file will be used instead of downloading from the internet.

c: Type[ITR.configs.PortfolioCoverageTVPConfig]
cta_file_path = None
_enrich_sbti_validated(company_data: pandas.DataFrame) → pandas.DataFrame

Load the CTA file and enrich the company data with the sbti_validated status. Skipped if sbti_validated is already populated in the data.

get_portfolio_coverage(company_data: pandas.DataFrame, portfolio_aggregation_method: ITR.portfolio_aggregation.PortfolioAggregationMethod) → float | None

Get the TVP portfolio coverage (i.e. what part of the portfolio has a SBTi validated target). Loads the CTA file and enriches company data with sbti_validated status before computing coverage, unless sbti_validated is already populated.

Parameters:

  • company_data – The company as it is returned from the data provider’s get_company_data call.

  • portfolio_aggregation_method – PortfolioAggregationMethod: The aggregation method to use

Returns:

The aggregated score
