ESG Sentiment detection


The esg-sentiment detector aims at categorizing ESG (Environmental, Social and Governance) news, social media posts or CSR (Corporate Social Responsibility) reports as negative or positive based on the actions or statements attributed to entities like companies, countries or institutions.

The detector also extracts the references to the above entities found in the text along with ESG data plus summary ESG performance data for the whole input document.

Hence, the detector aims at providing the users with an insightful ESG overview of a company, or set of companies, in order to add more context and useful information to structured data, which may be misleading if considered without any further reference.


Categorization works in a similar way to document classification and is based on a taxonomy.


Unlike the API resources dedicated to document classification, this is an information detector and the category tree of its taxonomy is not obtainable with API self-documentation resources like for document classification taxonomies, so it is indicated below.

The category tree includes all of the three macro areas of the ESG analysis, each of which is divided into a positive and a negative cluster for sentiment analysis purposes. A detailed layer of sub-categories for each macro area defines the relevant topics.

1000 Environment
    1100 Positive
        1110 Climate Impact
        1120 Biodiversity and Environmental Footprint

        1210 Climate Impact
        1220 Waste and Emissions Management

    • Biodiversity and Environmental Footprint: (positive/negative) engagement towards the preservation of biodiversity and the use of natural resources.
    • Environmental Opportunities: (positive only) innovations adopted by a company in order to protect the environment and fight climate change, as well as new business projects aiming at preserving the environment.
    • Waste & Emissions Management: (positive/negative) management and reduction of waste production and emissions other than CO2.
    • Environmental Crime: (negative only) illicit activities affecting the environment.

  • Social sub-categories:

    • Human Capital: (positive/negative) social quality of the working environment.
    • Workplace Safety and Product Safety: (positive/negative) refers to the security guaranteed on the workplace and the safety guaranteed for the product or service from the consumer's perspective.

    • Diversity and Inclusion: (positive only) inclusiveness and equality initiatives in terms of rights and representativeness.

    • Legal Compliance: (positive/negative) compliance with the relevant legislation.
    • Product Stewardship: (positive/negative) engagement towards product quality.

Along with the third level categories, the corresponding second and first level categories are always found in the categorization output. This allows you to see how the scores of the leaf categories are transmitted to the higher level categories in order to compute the overall sentiment indicators present in the ESG_SENTIMENT record of the extraction output (see below).
Only the third level categories, however, are directly triggered by the input text, so they are the only ones for which the positions to be highlighted in the text are provided.



The information extraction activity of the detector finds and returns records of extracted information. Each record contains data fields and its structure—the possible fields—is called template.
A template can be compared to a table and the template fields to the columns of the table, as shown in the following figure.


The detector extracts references found in the input text to entities performing ESG-related actions or making ESG-related statements.
Each extraction is a record of the ENTITY template with one or more occurrences of the following fields:

Field Description
entity Entity name
CO2_emission_cut CO2 emissions reduction (percentage)
CO2_emission_increase CO2 emissions increase (percentage)
certification_obtained An ESG certification
date Date of CO2 or pollution reduction/increase
inference Anaphora of the entity name
pollution_increased Emissions increase, other than CO2 (percentage)
pollution_decreased Emissions reduction, other than CO2 (percentage)
waste_increased Waste production increase (percentage)
waste_decreased Waste production decrease (percentage)
sanction Amount of money due by an entity because of code or law infringements


The detector also extracts summary ESG performance indicators for the whole document. They are records of the ESG_SENTIMENT template with these fields:

Field Description
overall_score Overall ESG sentiment score (no range)
overall_sentiment Overall sentiment polarity, either positive or negative based on the sign of overall_score
environment_performance_score Environment score
environment_sentiment Environment sentiment polarity, either positive or negative based on the value and sign of environment_performance_score
social_performance_score Social sentiment score (no range)
social_sentiment Social sentiment polarity, either positive or negative based on the value and sign of social_performance_score
governance_performance_score Governance sentiment score (no range)
governance_sentiment Governance sentiment polarity, either positive or negative based on the value and sign of governance_performance_score
sum_environment_rules Diagnostic information
sum_social_rules Diagnostic information
sum_governance_rules Diagnostic information
