The problem
Ocean acidification (caused by the uptake of atmospheric CO2 by the ocean) has increased more than 25 percent since pre-industrial times (based on observations over 30 years), and is expected to reach 100-150 percent by the end of the century. This growing acidification, along with overfishing and coastal eutrophication, is having serious consequences for marine life and ocean sustainability. Billions of people depend on oceans for their livelihood and food source, requiring greater efforts to conserve oceans. Corporations are critical to this effort, including through their overall climate efforts (such as reducing GHG emissions and other pollutants), direct use of ocean resources (such as fishing and shipping industries), engagement with supply chain partners on climate change and use of ocean resources, and participation in international efforts to address ocean use and climate change
How companies are rated
Ethos is using 253,526 unique data points since 2017 to rate companies, stocks and funds on healthy oceans, including from these metrics:
Financial performance
r =
Company ratings 1-yr return
Top 10 for healthy oceans
Top 50 for healthy oceans
S&P 500 Index
Bottom 50 for healthy oceans
Bottom 10 for healthy oceans
Healthy oceans has a slight positive correlation (
) with financial returns, meaning companies that perform better in this impact area tend to perform slightly better financially
