class ITR.portfolio_aggregation.PortfolioAggregationMethod(*args, **kwds)

Bases: enum.Enum

The portfolio aggregation method determines how the temperature scores for the individual companies are aggregated into a single portfolio score.

TETS = 'TETS'

MOTS = 'MOTS'

EOTS = 'EOTS'

ECOTS = 'ECOTS'

AOTS = 'AOTS'

static is_emissions_based(method: PortfolioAggregationMethod) → bool

Check whether a given method is emissions-based (i.e. it uses the emissions to calculate the aggregation).

Parameters:

method – The method to check

Returns:

static get_value_column(method: PortfolioAggregationMethod, column_config: Type[ITR.configs.ColumnsConfig]) → str

class ITR.portfolio_aggregation.PortfolioAggregation(config: Type[ITR.configs.PortfolioAggregationConfig] = PortfolioAggregationConfig)

Bases: abc.ABC

This class is a base class that provides portfolio aggregation calculation.

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 PortfolioAggregationConfig class and overwriting one of the parameters.

_calculate_aggregate_score(data: pandas.DataFrame, input_column: str, portfolio_aggregation_method: PortfolioAggregationMethod) → pandas.Series

Aggregate the scores in a given column based on a certain portfolio aggregation method.

Parameters:

• data – The data to run the calculations on

• input_column – The input column (containing the scores)

• portfolio_aggregation_method – The method to use

Returns:

The aggregates score
