Climate-aligned investing and ESG investing are frequently used interchangeably — but they use different data, apply different methodologies, and produce materially different portfolios. ESG investing uses aggregate third-party ratings from providers like MSCI or Sustainalytics to assess governance risk. Climate-aligned investing targets companies based on real-world warming trajectories, harm-category revenue exclusions, and net-zero commitment credibility. A company can score highly on an MSCI ESG rating while still deriving significant revenue from fossil fuels or weapons manufacturing.
