Low Carbon Indexes - MSCI

MSCI Low Carbon Indexes

The MSCI Low Carbon Indexes are intended to help identify potential risks associated with the transition to a low carbon economy while representing the performance of the broad equity market. Launched in 2014 they are the first index series designed to address two dimensions of carbon exposure: carbon emissions and fossil fuel reserves.

MSCI Low Carbon Indexes can be split into two index suites:

  • The MSCI Global Low Carbon Target Indexes re-weight stocks based on their carbon exposure in the form of carbon emissions and fossil fuel reserves. The indexes are designed to achieve maximum carbon exposure reduction and achieve 0.3% (30 basis points) ex ante tracking error target while minimizing the carbon exposure relative to their parent indexes.
  • The MSCI Global Low Carbon Leader Indexes aim to achieve at least 50% reduction in the carbon footprint of the parent index by excluding companies with the highest carbon emissions intensity and the largest owners of carbon reserves (per dollar of market capitalization). They also aim to minimize the tracking error relative to their parent index.


  • The indexes are designed to address two dimensions of carbon exposure – carbon emissions and fossil fuel reserves.
  • They aim to have a low tracking error relative to the parent index.
  • The indexes’ stock selection process utilizes MSCI ESG Carbon Metrics and ESG Research.
