Abstract: We show that individual bellwether investors can trigger large capital market shifts and sharply reduce a socially harmful activity by publicly blacklisting implicated firms. In 2016, Norway’s massive Oil Fund announced that it had divested or begun monitoring coal-intensive companies in its broad, global portfolio. We estimate a roughly 18% relative decrease in targeted firms’ greenhouse gas emissions—comparable to that of the EU Emissions Trading System—alongside decreased coal activity, emissions intensity, market valuations, and satellite-measured air pollution around their facilities. The coal exit swayed other large and scrutinized investors to reallocate away from targeted firms.
