Green Asset Ratio (GAR) - ESG Reporting Definition and Explanation
The Green Asset Ratio (GAR) is a key regulatory ESG metric for European financial institutions, measuring the proportion of environmentally sustainable assets within a bank's total balance sheet for robust ESG reporting.
Why the Green Asset Ratio is Critical for SMEs
Since 2024, large European banks have been required to disclose this metric transparently within their ESG reporting. For SMEs, this creates substantial pressure on their core banks, which now prefer to grant loans to companies that can demonstrate sustainability in line with EU Taxonomy criteria. Businesses lacking ESG transparency risk poorer credit ratings and higher interest rates.
How Bank Disclosure Requirements Cascades Down to SMEs
Although the GAR is primarily a banking requirement, it trickles down to small and medium-sized enterprises through three key mechanisms:
Banks require reliable ESG data from borrowers to classify loans as "green"
Banks offer preferential terms and conditions for sustainable finance
The GAR creates direct comparability between banks for investors and regulators
The Technical Foundation: EU Taxonomy
GAR calculations are based on the EU Taxonomy. For a loan to qualify as "green", three criteria must be met: a substantial contribution to environmental objectives, compliance with the "Do No Significant Harm" (DNSH) principle, and adherence to minimum safeguards for labour and human rights.
