A coalition of activists has designated 22 September as a global day of action against hydraulic fracturing.
The "Global Frackdown," as it is billed, will aim to "send a message to elected officials in our communities and across the globe that we want a future fueled by clean, renewable energy, not dirty, polluting fossil fuels," said a statement from Food and Water Watch, which is coordinating the event.
Organisers are planning loosely affiliated events including protests, airings of the anti-fracking "Gasland" film and charity races.
The gatherings are taking place in places including the US, Europe and South Africa.
Many environmentalists are deeply concerned about the impacts of shale drilling, including the hydraulic fracturing process used to stimulate production, on local water and air supplies.
Vocal activism has helped to slow down or in some cases place bans on the process.
