ABC chairwoman Ita Buttrose has suggested the public broadcaster and other corporations should consider ways to make their boards more ethnically diverse and criticised politicians who do not respond to climate change concerns as "blinkered".

Ms Buttrose said an ABC survey of 50,000 people that found the majority of Australians were concerned about issues like the environment and the broadcaster was trying to work out how to incorporate those interests into its coverage.

"Much of the media is white and we're not all white," Ms Buttrose said on ABC Radio National on Tuesday morning.

Ms Buttrose said the issue of ethnic diversity was one for all corporate leaders.
