APIs solve this by standardising how systems communicate, ensuring consistent data flows from HR, facilities, procurement, and supply chain management platforms.

Understanding the Four ESG Data Types

ESG data encompasses distinct categories that organisations must track systematically Brightest:

Environmental Data captures emissions (Scope 1-3), energy consumption, water usage, and waste generation. Modern platforms use established emissions factors from IEA, DEFRA, and EPA Pulsora, or customised calculations for specific facilities and regions, ensuring accurate carbon footprint mapping.

Social Data measures workforce diversity, labour practices, health and safety metrics, and community impact. Companies gather these through employee feedback systems, supplier assessments, and stakeholder surveys Manifest Climate, providing qualitative and quantitative insights into workplace culture and social responsibility. Comprehensive assessment frameworks incorporate these data points, stakeholder engagement, and controversy analysis to quantify ESG performance and risks.

Governance Data tracks board composition, executive compensation, business ethics, and compliance frameworks. These metrics increasingly influence investor decision-making, as ESG scores help organisations identify potential risks like labour disputes or human rights violations Nordic APIs.

Financial Data complements traditional ESG metrics by calculating intensity ratios and performance indicators, enabling companies to benchmark their company’s ESG performance against industry peers using both qualitative and quantitative data whilst assessing the material ESG factors that impact long-term value creation. Revenue metrics are also used to assess ESG indicators, such as the percentage of revenue tied to specific industries or the alignment of revenue streams with sustainability standards.

How to Collect Data for ESG: Modern Methodologies
