Renewable energy supplier Good Energy has urged the BBC to devote more time and resources to informing its audience about climate change.
In an open letter to the director of the corporation, Lord Tony Hall, the founder and CEO of Chippenham-based Good Energy, Juliet Davenport, described climate change as "the most significant crisis facing humankind today."
While praising the BBC for its recent documentary Climate Change: The Facts, she pointed out that it was the broadcaster's first programme on the issue in 10 years.
She also welcomed new guidance on climate change reporting for BBC journalists, which would be supported by a one-hour training session, but questioned whether it was enough.
And she reminded the director general of an interview broadcast on radio 4 last month, during which presenter John Humphrys hectored former Labour leader Ed Miliband, who was launching the cross-party climate change task force. Listeners accused the presenter of "belligerence" and "hectoring".
In her letter, she called for the broadcaster to discuss the solutions to climate change, as well as the problems.
"Recent research from BAFTA on environmental coverage in one year of UK television showed a tendency to emphasise the problems over the solutions," she wrote.
"Mentions of climate change and global warming, for example, far outweighed those of electric cars or solar power. However, these technologies have an equal role to play in understanding the impacts of our changing world."
