Polls show that most people now understand that climate change is real — so you’re less likely to have to fight that battle at the Thanksgiving table this year. But what, your cranky uncle wants to know, are we going to do about it?

We think the answer is to move to a 100% clean future, which is a bold goal, but one we need since climate change is such a big problem. Here’s how to explain it over pie.

What is a 100% clean future?

A 100% clean future means we don’t produce any more climate pollution than we remove — resulting in net zero pollution. To do that, we need a lot more clean energy, and cost-effective ways to take climate pollution out of the air. We have to get started now, make big progress over the next ten years and get to 100% clean by 2050.

How will it work?

A 100% clean future is practical and achievable because it lets us have a mix of energy sources, as long as the overall balance is zero pollution. So pollution still produced by some factories, for example, will be balanced out by having bigger forests or farming practices that remove carbon from the air. New carbon dioxide removal technologies could pull carbon pollution directly out of the atmosphere, too. They’re not cost-effective yet, so we need more research and development.
