Sustainable Finance Taxonomy: Classifying Green Investments

By Climate Finance Team

Sustainable finance taxonomies are classification systems that define which economic activities qualify as environmentally sustainable. These frameworks are essential for preventing greenwashing and directing capital toward genuine climate solutions.

The EU Taxonomy

The EU Taxonomy Regulation established a comprehensive classification system with six environmental objectives: climate change mitigation, climate change adaptation, sustainable use of water, transition to a circular economy, pollution prevention, and protection of biodiversity. Activities must make a substantial contribution to at least one objective without significantly harming the others.

Global Taxonomy Development

Following the EU's lead, numerous jurisdictions are developing their own sustainable finance taxonomies. Countries including China, South Korea, Singapore, and South Africa have published or are developing classification systems, though approaches vary significantly in scope and stringency.

Practical Implications

For financial institutions, taxonomy alignment affects product labeling, reporting obligations, and investment strategies. Companies must assess which of their activities qualify as taxonomy-aligned and disclose this information to investors and regulators.

Challenges in Implementation

Implementing taxonomies requires robust data collection, consistent interpretation of technical screening criteria, and adequate verification processes. The complexity of assessment, particularly for companies with diverse activities, remains a practical challenge.
