A challenge for the positive alignment ESG approach is the diversity of ESG ratings methodologies.

Diversity of ESG ratings methodologies (B): Different ESG rating agencies use various methodologies, criteria, and weightings to assess and score companies. This diversity can lead to inconsistent ratings for the same company, making it challenging for investors to align their portfolios positively based on ESG criteria. The lack of standardization in ESG ratings methodologies can create confusion and difficulty in accurately comparing ESG performance across companies.

Relative complexity of implementation (A): While implementing a positive alignment approach can be complex, it is the diversity in ratings methodologies that poses a more significant challenge.
