In 2015, we took the first steps to measure, disclose, and set a baseline for the carbon footprint of our portfolios as an early signatory and ambassador for the Montréal Carbon Pledge, which is overseen by Principles for Responsible Investment. In our 2016 analysis, we add metrics on carbon intensity and weighted average intensity besides total greenhouse gas (GHG) emissions. The results show that Boston Common’s major strategies produce fewer emissions and are less carbon-intensive than their respective benchmarks, primarily due to stock selection rather than allocation. For example, our Sustainable Climate strategy produces 70% fewer emissions and is 62% less carbon-intensive (weighted average) than its benchmark.
In 2017, our International Sustainable Climate Equity and All Country International Equity Strategies generate, respectively, 71% and 59% fewer emissions and are 52% and 34% less carbon intensive than the MSCI ACWIxUS Benchmark.
Our International Equity Strategy generates 47% fewer emissions and is 21% less carbon intensive than the MSCI EAFE benchmark.
Our US Sustainable Climate Equity and US Large-Cap Core Equity strategies generate, respectively, 73% and 70% fewer emissions and are 67% and 61% less carbon intensive than the S&P 500® benchmark.
