"One obvious way to help fund a citizen's dividend or guaranteed income would be to levy a carbon tax, and therefore you'd be doing something very positive for the environment. ... I think there's a strong relationship between these two issues. On the one hand we have to take on these environmental challenges, on the other hand we've got this unfolding trend going on which is impacting people's income security and those two are directly related: as long as people perceive that they're not secure economically, they're worrying about paying their rent next month, or they're worried about putting food on the table, they're not gonna be able to focus on longer-term environmental issues. And that's one of the big problems we see with climate change: if you look at surveys of the American people, they acknowledge that climate change is an issue, but it's also absolutely at the bottom of their list of priorities, and the top of their list, of course, is jobs, it's incomes. So I really think that if we want to have meaningful progress on environmental issues like climate change we need to put this whole issue of income security and income inequality first-hand at the top."
