Prince Charles has said the idea of becoming a granddad has spurred on his green beliefs.
In an interview on ITV's This Morning he told presenters Phillip Schofield and Holly Willoughby he was "thrilled" at the prospect of William and Kate having their first child this summer.
He said he did not want the boy or girl to ask him why he had not done more to tackle issues such as climate change.
He said: "I've gone on for years about the importance of thinking about the long term in relation to the environmental damage, climate change and everything else.
"Clearly, now that we have a grandchild (on the way), it makes it even more obvious to try to make sure we leave them something that isn't a total poisoned chalice."
