Climate change was mentioned on British TV less times in a year than cats, picnics and cake, analysis has found.
Subtitles of 128,719 programmes, excluding news, over a year were analysed by Deloitte for the British Academy of Film and Television Arts (BAFTA) and TV sustainability project albert.
The findings, which revealed climate change is only mentioned slightly more times than zombies, coincided with the launch of a new guide to help industries weave more environmental messages into programmes.
The research claimed climate change was mentioned 3,125 times, while other “green” terms such as clean air and food waste only got a few hundred mentions each.
Compared to this, cats were mentioned 14,454 times, picnics on 5,949 occasions, cake 46,043 times and Brexit 68,816 times.
Pippa Harris, chairwoman at BAFTA, said: "The TV industry's call to address climate change is clear.
"Reducing our impact is a given, but our real opportunity lies in the programmes we make, and in our ability to use powerful human stories to connect audiences with the world around them.
The results of the resarch found climate change was mostly mentioned when discussing the environment rather than being brought into conversation from other topics.
The report was published as Planet Placement, a guide to challenge and inspire the industry to weave sustainability messages into on screen content regardless of genre.
Aaron Matthews, head of industry sustainability at albert, said: "We must think creatively and look for other ways to bring sustainability messages to our screens that are both optimistic and inspirational.
"I look forward to revisiting this data in a year or two, to see how things have changed."
