Declan's kicked off what's to be a year-long series for us this morning, introducing us to our Breakfast 'low carb' family.
The idea has nothing to do with chips - and everything to do with emissions.
We have challenged the family, the Hawksworths who live in Castle Donington, to see if they can reduce their emissions (they got in touch when we asked for volunteers just before Christmas).
We'll return once a month to see how they get on and also, more importantly to explore some of the issues around climate change and global warming.
But it's fair to say we also had some scepticism around the science of global warming, with a few people getting in touch to dispute whether it is really a serious issue.
On the science, we have pledged to explore those questions, with the Hawksworths helping put the questions.
Others felt that it was unfair to single out a family for our 'low carb' challenge - we should be "going after big business" instead.
My answer to that final point is that we do - and will continue to - question businesses on their environmental credentials.
Last week, we challenged the boss of Marks and Spencer, Stuart Rose, on the issue of food miles.
Declan frequently puts similar questions to the CEOs and chairmen who visit his studio.
Finally, some got in touch wondering why we cover so many stories relating to the environment, CO2 emissions and recycling.
"Frankly I am sick of listening to Breakfast going on and on about green issues", was one such comment.
Maybe we do too much of it? And we must certainly think about the sheer volume of such stories we cover. But we get an enormous response every time we do.
