I don't doubt this, but it's weird how they never come up with masculinity as the explanation for why the predominantly male leaders of the oil and gas, logging, and mining industries continue to kill the earth.

like i'm not gonna shit on a field of research i don't have experience in, but like these are the behaviors they studied (not directly, but through mechanical turk survey):

The description included five feminine PEBs (line drying washed clothes, decorate a room with light colors that reflect daylight, recycling, buy new clothes from a sustainable designer brand, and use reusable shopping bags), five neutral (buying energy efficient CFL and LED bulbs; unplug your chargers, which draw current when the devices battery is full; opening windows rather than using air-conditioning; use safety razors instead of disposable ones; and paying bills online), or five masculine PEBs (donating to a waterfowl sportsman’s group, adhere to a vehicle maintenance plan, keep car tires at the proper pressure, caulking windows and doors, and using online video gamesrather than purchasing video game disks;

Activism is briefly mentioned as a masculine behavior in the intro, but otherwise not included in this study. In fact the focus of the study isn't on what actions are necessary to protect the environment and how our gendered social conditioning might hinder that, so much as on trying to determine where gender might be hiding in the broad field of potentially pro-environmental behaviors.
