Quotes about Emissions

Correct me if I'm wrong, but isn't driving around on a bus and having a campfire kind of adding to the environment problem?

Domesticated cows deliver more greenhouse gases to the atmosphere than do all the world's vehicles—autos, trucks, trains, aircraft, ships—combined.

What the Paris agreement now does is say to China and India and other countries that are potentially polluting, come on board. Let's work together so you guys do the same thing.

If I hear that Quito, Ecuador, is doing something to have a whole area of town that's zero emissions, and we're thinking about that in Los Angeles' downtown, I'm like, 'I better catch up.'

Eighty percent of air pollution comes from plants and trees.

the math suggests you'd need somewhere around 50 acres' worth of trees, planted in tropical areas, to absorb the emissions produced by an average American in her lifetime. Multiply that by the population of the United States, and you get more than 16 billion acres, or 25 million square miles, roughly half the landmass of the world.

The reason the world emits so much greenhouse gas is that—as long as you ignore the long-term damage they do—our current energy technologies are by and large the cheapest ones available. So moving our immense energy economy from "dirty," carbon-emitting technologies to ones with zero emissions will cost something.

Because every bit of carbon we put into the atmosphere adds to the greenhouse effect. There's no getting around physics.

To sum up, the path to zero emissions in manufacturing looks like this: Electrify every process possible. This is going to take a lot of innovation. Get that electricity from a power grid that's been decarbonized. This also will take a lot of innovation. Use carbon capture to absorb the remaining emissions. And so will this. Use materials more efficiently. Same.

2. What's Your Plan for Cement? If you're talking about a comprehensive plan for tackling climate change, you need to consider everything that humans do to cause greenhouse gas emissions.

We already know the emissions number; it's 51 billion tons each year. As for the cost of removing a ton of carbon from the air, that figure hasn't been firmly established, but it's at least $200 per ton. With some innovation, I think we can realistically expect it to get down to $100 per ton, so that's the number I'll use. That gives us the following equation: 51 billion tons per year x $100 per ton = $5.1 trillion per year

Fifty-one billion is how many tons of greenhouse gases the world typically adds to the atmosphere every year.
