While Gen Z worries about the environment, their parents and grandparents are far more likely to take steps to address climate change, according to research by the Oliver Wyman Forum. Climate Catalysts, about 13% of the global population, have spent years recycling, buying carbon offsets, and writing to government officials. But as the severe weather has worsened, they’ve grown more disappointed by the lack of progress by world leaders.

This largely 35-and-older urban crowd isn’t waiting any longer. Climate Catalysts expect companies to use their brands to engage in social issues. Almost 75% of them avoid companies that don’t work to stop climate change, and 46% plan to boycott companies that don’t change.
