You’re never going to get the amount of CO2 emitted to go down unless you deal with the one magic metric, which is CO2 per kilowatt-hour.

We should remember that there are nations which meet more than 30 to 60% of their power requirements through the nuclear power system.

All the waste in a year from a nuclear power plant can be stored under a desk.

I remember when I was younger, and in school, our teachers showed us films of plastic in the ocean, starving polar bears and so on. I cried through all the movies. My classmates were concerned when they watched the film, but when it stopped, they started thinking about other things. I couldn’t do that. Those pictures were stuck in my head.

Evolution can go to hell as far as I am concerned. What a mistake we are. We have mortally wounded this sweet life-supporting planet – the only one in the whole Milky Way – with a century of transportation whoopee.

In just a few hundred years, we will have to cover the entire surface of the Earth in solar cells if we want to continue to grow our energy usage.

The universal utilization of water power and its long-distance transmission will supply every household with cheap power and will dispense with the necessity of burning fuel. The struggle for existence being lessened, there should be development along ideal rather than material lines.

What is a farm but a mute gospel?

We should no longer measure our wealth and success in the graph that shows economic growth, but in the curve that shows the emissions of greenhouse gases.

Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.

Nothing is being done to stop the climate and ecological emergency from happening and to secure the future wellbeing for future generations.

The situation the Earth is in today has been created by unmindful production and unmindful consumption. We consume to forget our worries and our anxieties. Tranquilising ourselves with over-consumption is not the way.

The reality is gas prices should be much more expensive then they are because we’re not incorporating the true damage to the environment and the hidden costs of mining oil and transporting it to the U.S. Whenever you have an unpriced externality, you have a bit of a market failure, to the degree that eternality remains unpriced.

If you think in terms of a year, plant a seed; if in terms of ten years, plant trees; if in terms of 100 years, teach the people.

Obviously Tesla is about helping solve the consumption of energy in a sustainable manner, but you need the production of energy in a sustainable manner.

We will have to leave this planet, and we’re going to leave it, and it’s going to make this planet better.

It is good to realize that if love and peace can prevail on earth, and if we can teach our children to honor nature’s gifts, the joys and beauties of the outdoors will be here forever.

I personally have stopped flying. I have stopped eating meat and dairy.

I was born in London in England in 1934. I went through, as a child, the horrors of World War II, through a time when food was rationed and we learned to be very careful, and we never had more to eat than what we needed to eat. There was no waste. Everything was used.

I’ve actually made a prediction that within 30 years a majority of new cars made in the United States will be electric. And I don’t mean hybrid, I mean fully electric.

As soon as a redwood is cut down or burned, it sends up a crowd of eager, hopeful shoots, which, if allowed to grow, would in a few decades attain a height of a hundred feet, and the strongest of them would finally become giants as great as the original tree.

The reason we should do a carbon tax is because it’s the right thing to do. It’s economics 101, elementary stuff.

What is the use of a house if you haven’t got a tolerable planet to put it on?

Taking bold action on climate change simply makes good business sense. It’s also the right thing to do for people and the planet. Setting a net-zero GHG emissions target by 2050 will drive innovation, grow jobs, build prosperity, and secure a better world for what will soon be 9 billion people.

I resigned from the Marine Corps and flying in 1974, even though I loved them both. I quit because I no longer wanted to fight for peace. Instead, I believe we can build a more sustainable peace by working for prosperity.

The extraction of oil, coal and minerals brought, and still brings, a cost to the environment.

There aren’t many things that are universally cool, and it’s cool not to litter. I’d never do it.

We should all grow our own food and do our own waste processing, we really should.

Treatment without prevention is simply unsustainable.

A diplomatic solution that puts significant and verifiable constraints on Iran’s nuclear program represents the best and most sustainable chance to ensure that America, Israel, the entire Middle East will never be menaced by a nuclear-armed Iran.

Even if producing CO2 was good for the environment, given that we’re going to run out of hydrocarbons, we need to find some sustainable means of operating.

To shake your rump is to be environmentally aware.

I think it is a good thing to buy less and choose well – it’s good for the environment and to be fair it’s also good for me because my clothes are quite expensive.

It’s not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it’s a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.

I talk to fashion designers and say I want some money to save the rainforest, and they say, ‚Oh, I agree with you completely Vivienne. Yes, climate change, it’s definitely happening,‘ but they don’t feel that they can do anything about it; they don’t even think ‚Well let’s stop it!‘

By stopping flying, you don’t only reduce your own carbon footprint but also that sends a signal to other people around you that the climate crisis is a real thing and that helps push a political movement.

Economists treat economics as if it is a pure science divorced from the facts of life. The result of this false accountancy is a willful confusion under cover of which industry wreaks its havoc scot-free and ignores the environmental cost.

Even if the economy crashes, we will still burn oil.

Many people, especially in the U.S., see countries like Sweden or Norway or Finland as role models – we have such a clean energy sector, and so on. That may be true, but we are not role models.

We have got to change our ethics and our financial system and our whole way of understanding the world. It has to be a world in which people live rather than die; a sustainable world. It could be great.

At Virgin, we have always backed the power of the entrepreneur and inventor to find solutions to tricky problems. Why should climate change and the battle against carbon be any different?

War contributes greatly to global warming, which shouldn’t surprise us. All those bombs going off, all those rockets, all those planes and helicopters. All that fuel of various kinds being used. It pollutes the air and water of this very fragile and interconnected planet.

In 1961, the United States began chemical warfare in Vietnam, South Vietnam, chemical warfare to destroy crops and livestock. That went on for seven years. The level of poison – they used the most extreme carcinogen known: dioxin. And this went on for years.

We are at a time in history where everyone with any insight of the climate crisis that threatens our civilisation – and the entire biosphere – must speak out in clear language, no matter how uncomfortable and unprofitable that may be.

I think California has the best energy.

A business that makes nothing but money is a poor business.

The effects of climate change are real and must be acted on.

There is a sufficiency in the world for man’s need but not for man’s greed.

I think there are more politicians in favor of electric cars than against. There are still some that are against, and I think the reasoning for that varies depending on the person, but in some cases, they just don’t believe in climate change – they think oil will last forever.

Every once in a while, I get mad. ‚The Lorax‘ came out of my being angry. The ecology books I’d read were dull… In ‚The Lorax,‘ I was out to attack what I think are evil things and let the chips fall where they might.

The threat to the planet is us. It’s actually not a threat to the planet – it’s a threat to us.

Any fool can destroy trees. They cannot run away; and if they could, they would still be destroyed – chased and hunted down as long as fun or a dollar could be got out of their bark hides, branching horns, or magnificent bole backbones.

More businesses should be following Apple’s stance in encouraging more investment in sustainability.

We could have saved the Earth but we were too damned cheap.

The trouble with energy farming is that the energy isn’t always where you want to use it, and it isn’t always when you want to use it.

I did this book ‚Harvest for Hope,‘ and I learned so much about food. And one thing I learned is that we have the guts not of a carnivore, but of an herbivore. Herbivore guts are very long because they have to get the last bit of nutrition out of leaves and things.

The environment is everything that isn’t me.

I have a company, and I’ve got to think about that. I’m trying to do my best there, and that’s a much harder task. We recycle as much as possible, and we conserve. But I’ve always been one to save everything – I even walk up stairs on the very inside or the very outside to not wear out the tread.

There are thousands of ways to take action. For example, plant trees, pick up litter, join an organisation or movement that makes a difference and especially try to influence adults and put pressure on people in power.

To me, a leader is someone who holds her- or himself accountable for finding potential in people and processes. And so what I think is really important is sustainability.

It’s obviously tricky to convert cellulose to a useful biofuel. I think actually the most efficient way to use cellulose is to burn it in a co-generation power plant. That will yield the most energy and that is something you can do today.
