Over 2023, an often-tumultuous year on many fronts, the MSCI ESG and MSCI Climate Indexes met or exceeded their stated objectives. Let’s take a closer look.
MSCI ESG Indexes
The MSCI ESG Indexes are constructed to reflect various investor motivations, such as excluding controversial stocks, integrating ESG considerations while maintaining a risk profile similar to the parent index, selecting the highest-rated ESG stocks in each sector or maximizing an index’s ESG score while limiting tracking error to the parent index.
A review of the 2023 performance of the flagship MSCI ESG Indexes shows that the MSCI SRI Indexes had the greatest return dispersion across regions — a 10.5% spread between the U.S. and Japan — while the MSCI ESG Focus Indexes had the lowest variability — a 1.1% difference between the U.S. and emerging markets (EM).
2023 performance of the flagship MSCI ESG Indexes across regions
During 2023, the MSCI ESG Indexes’ returns were positively impacted by the volatility and downward trend in oil prices and the effect on the Global Industry Classification Standard (GICS®)[1] energy and utilities sectors. The performance of the Magnificent Seven, thanks in part to the growth in artificial intelligence, boosted returns in the information-technology (IT), communication-services and consumer-discretionary sectors. Given the outperformance of the MSCI ACWI ESG Screened and MSCI ACWI SRI Indexes, we examined these in greater detail to understand how their methodologies impacted their returns.
Two sectors and stock-specific return boosted performance
The MSCI ACWI ESG Screened and MSCI ACWI SRI Indexes had the highest average active exposure to the IT sector, and both had the lowest active exposure to the energy sector. The MSCI ESG Indexes are constructed to avoid sector concentration, but because the MSCI ESG Screened Indexes also apply a 30% reduction in carbon emissions relative to the parent index, they were underweight in the energy sector. In contrast, the MSCI ACWI SRI Indexes are designed to be sector-neutral, but sharp price movements between index rebalances can create sector underweights or overweights.

Our performance attribution shows that within the IT sector, IT services and software and semiconductor companies boosted returns of the MSCI ACWI ESG Screened and MSCI ACWI SRI Indexes. The energy sector’s oil and gas exploration and production companies also contributed positively. And although these sectors added to the outperformance of both indexes, the Magnificent Seven accounted for about 30% of the return of the MSCI ACWI Screened Indexes and most of the stock-specific return of the MSCI ACWI SRI Indexes.

A range of ESG profiles are on offer
Compared to their parent index, the MSCI ACWI ESG Indexes offer different combinations of value- or constraints-based considerations and integration of financially relevant MSCI ESG Ratings — for example, higher ESG scores (except for the MSCI ACWI ESG Screened Indexes[2]) and lower red-flag ESG controversies.

A closer look at the sector-level performance of the MSCI ACWI SRI Index shows that the weighted-average ESG score for the IT sector was the highest among all sectors at the end of 2023.

MSCI Climate Indexes
Like the MSCI ESG Indexes, the MSCI Climate Indexes are constructed to represent one or more of the following investor goals: reduce carbon emissions, manage climate risks, increase exposure to green revenue and align with net-zero objectives. Over 2023, the MSCI ACWI Climate Action and MSCI ACWI Climate Change Indexes outperformed the MSCI ACWI Index by 2.7% and 6.5%, respectively.

While various industries, including software and semiconductors, contributed to the active return of the MSCI ACWI Climate Indexes, the performance of the Magnificent Seven generated most of the stock-specific return.[3] In Japan and EM, value stocks outperformed during the year, negatively impacting those regions’ MSCI Climate Action, MSCI Climate Change and MSCI Climate Paris Aligned Indexes because they underweighted value stocks, which tend to have higher carbon emissions.[4]
We compared several metrics that, while not common to all indexes, can help us understand current levels of decarbonization, percentage of companies disclosing targets aligned with the Science Based Targets initiative (SBTi) and percentage of revenues derived from green businesses. As of December 2023, compared to their parent index, all of the MSCI ACWI Climate Indexes had lower carbon intensity, higher green revenues (except for the MSCI ACWI Low Carbon Leaders Index) and higher SBTi-approved targets (except for the MSCI ACWI Low Carbon Leaders and ACWI Low Carbon Target Indexes).

MSCI ESG and Climate Indexes met or exceeded stated objectives
In 2023, even as markets experienced the growth of the Magnificent Seven and felt the impact from ongoing volatility in the oil market, the MSCI ESG Indexes continued to meet their stated objectives, including maximizing ESG score while limiting tracking error or selecting the highest-rated ESG stocks by sector. And for the year, the MSCI Climate Indexes showed lower carbon emissions and, generally, a larger percentage of revenues from green businesses when compared to their parent index.
