Climate change is a global problem. The planet is warming because of the growing level of greenhouse gas emissions from human activity. If this trend continues, truly catastrophic consequences are likely to ensue from rising sea levels, to reduced water availability, to more heat waves and fires.
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?
Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.
hen the price of carbon reaches $100 a tonne, then it will become an economically viable business proposition to start taking CO? out of the atmosphere and sequestering it underground.
Burning natural gas will not save us from climate change. It's the same as burning any other carbon-based fuel.
I enjoy punk, the attitude as well as the music, but I don't feel like I have to be a carbon copy of it and invite all this controversy, just to be punk rock.
Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organise themselves into a professor of chemistry? What's the motive?
One of the best ways of reducing both CO2 emissions and poverty in the South would be to strengthen the existing, decentralised demographic pattern by keeping villages and small towns alive. This would allow communities to maintain social cohesion and a closer contact with the land.
I think we need to price carbon; there's no question about it. The way we do it needs to be based on science and not political debates and attacks, and that's why I'm drawing on experts and best practices from around the world.
The most effective way to reduce your carbon footprint is to fly less often. If everyone took fewer flights, airline companies wouldn't burn as much jet fuel.
Global warmers predict that global warming is coming, and our emissions are to blame. They do that to keep us worried about our role in the whole thing. If we aren't worried and guilty, we might not pay their salaries. It's that simple.
Using Waze, they're saving time on the road, money on gas, and emissions into the environment - a proposition they really can't turn down. But more than that, drivers use Waze because they feel they are part of a community, working together to overcome the global headache that is traffic.
What the world needs most for its stability, and what the U.S. needs for its national security, is economic growth, which is driven first and foremost by expanded carbon use.
Most reputable scientists agree that climate change is real and that the effects are likely to be bad. But nobody can say for sure exactly what 'bad' means. The safest and most equitable way out of this horrific mess is simple: cut fossil-fuel emissions.
A national carbon tax would devastate an already struggling American economy, force the cost of gas at the pump to jump even higher, and kill millions more jobs here at home.
Here's the truth: even if countries like the United States curb our emissions, if growing countries like India - with soaring energy needs - don't also embrace cleaner fuels, then we don't stand a chance against climate change.
I'm anti-tax, but I'm pro-carbon tax.
On the path to a low-carbon, clean-energy future, we need cleaner, non-intermittent sources of power that will allow us to keep the lights on when the wind isn't blowing or the sun isn't shining.
Do not, under any circumstances, belittle a work of fiction by trying to turn it into a carbon copy of real life; what we search for in fiction is not so much reality but the epiphany of truth.
I did a lot of work on energy efficiency at the White House. By the time I left we had taken the equivalent of six hundred cars a year off the road in reduced greenhouse gas emissions just in the White House complex.
I'm passionate about caring for this planet. I'd like to bring awareness to ways that individuals can reduce their carbon footprints without waiting for governments to change things on a policy level.
But reducing harmful emissions, abating our dependence on foreign oil and developing alternative renewable energy sources have benefits that go beyond environmental health, they improve personal health, enhance national security and encourage our nations economic viability.
Investigations during the last few decades have brought hydrogen instead of carbon, and instead of CO2 water, the mother of all life, into the foreground.
The body can endure compromise and the mind can be seduced by it. Only the heart protests. The heart. Carbon-based primitive in a silicon world.
Grief is an element. It has its own cycle like the carbon cycle, the nitrogen. It never diminishes not ever. It passes in and out of everything.
The home is the planet. Unless you're a Martian, you know, we're sharing the planet. And - and the emissions don't stop and CO2 doesn't stop with the border between France, Spain or between Canada and the United States.
We have at most ten years—not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions.
There's a lot of evidence that shows that if we push as hard as we need to for net-zero emissions, we'll find ourselves with cities that are more secure, healthier, and have more economic opportunity - are frankly better cities to live in - than if we settle for the status quo.
Cities generate most of the global economy, and most of its energy use, resource demands and climate emissions. How we build cities over the next decades will largely determine whether we can deliver a bright green future.
If the knowledge of the cost of the carbon tax in itself would cause injury to the Canadian economy, then that cost must be even worse than we have imagined.
The fact is that any carbon legislation is designed to make us not use coal. So if you're a state that has a lot of coal, you're going to get hammered.
Australia has suffered a decade of drought, epic floods, a Category 5 cyclone, and a plague of locusts. But just because Aussies have the biggest carbon footprint in the world, it doesn't mean they're stupid.
To be able to transform societies and economies to low-carbon ones was an amazing challenge. To influence and to facilitate such an important transformation in the world would be like witnessing something of industrial revolution proportions.
I wouldn't have voted for the war in Iraq, which has cost us trillions we could have been spending on a carbon-free economy, affordable college, and single-payer health care.
If we don't cut carbon's money pipeline, we will pay for their gasoline with floods, droughts, fires, super storms, drowned cities, mass extinctions, wars, and collapsing civilizations.
If we got more efficient with electric grid capacity, we would substantially reduce our carbon footprint, and people would be likely to copy us.
About half of all potential future global warming emissions from United States fossil fuels lie in oil, gas and coal buried beneath our public lands, controlled by the federal government and owned by the American people - and not yet leased to private industry for fuel extraction.
The sooner the US puts a cap on our dangerous carbon pollution, the sooner we can create a new generation of clean energy jobs here in America.
I do not believe we can effectively move Australia to a lower emission economy, which is what we need to do if we're going to make a contribution to a global reduction in greenhouse gases, without putting a price on carbon.
Ultimately, I do want us to be a transformative government. I want, when we've left, for people to say we're not just clean-green anymore: we're carbon neutral, or we're striving to be.
We've built a company that distributes a pair of eyeglasses to someone in need for every pair sold; that purchases carbon offsets; and that hosts mentoring programs at the office.
One of the reasons that people, many people, many environmentalists are critical of President [Barack] Obama's policies towards global warming is on the one hand he says the right things and he says he's committed to trying to reduce our current emissions.
We need robust sustainability regulations for shipping that are internationally recognised and respected. This will ensure shipping plays its part in the global transition to carbon neutrality.
If you had a carbon tax, you'd have less cars and more bicycles, more people getting around on foot and by public transport.
I enjoy punk, the attitude as well as the music, but I don't feel like I have to be a carbon copy of it and invite all this controversy just to be punk rock.
Even if we can solve the carbon problem for coal, it is still a non-renewable resource. At some point, coal supplies will drop.
There are some really wealthy hedge fund billionaires in San Francisco who have pledged a lot of money for Democratic candidates to argue for cap and trade and carbon tax and all these things.
The U.S. has a proud history of cleaning up our air through technological innovation. We did it with leaded gas, acid rain and countless other pollutants, and we can do it with carbon pollution, too.
Julianne Moore and Michael Keaton began in 1980s soap operas and 1970s sitcoms, respectively, such ancient history by show business standards that you need carbon dating to measure their careers.
By taxing CO2, firms and households would have an incentive to retrofit for the world of the future. The tax would also provide firms with incentives to innovate in ways that reduce energy usage and emissions - giving them a dynamic competitive advantage.
Proponents of efficiency standards argue that they save consumers and businesses money, reduce energy use, and reduce emissions. But families and businesses already understand how energy costs impact their lives and make decisions accordingly.
I've got an electric little motorcycle that I go to the supermarket with every day, and it's powered by the solar panels, so it's really got a zero carbon footprint.
Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen, and nitrogen struggle for billions of years to organize themselves into a professor of chemistry? What's the motive?
Wall Street is littered with clever plans to use financial instruments to change behavior - carbon trading, for example. Some have changed the world, and others failed miserably.
Both San Francisco and New York are taking bold, sweeping action to reduce emissions, make our infrastructure more resilient and improve the health of our people. We are also leading the charge against those who continue to deny the existence of climate change.
We're not a manufacturer, or an airline, but we do use energy. Printing and publishing newspapers, producing films and television programs, operating 24-hour newsrooms. It all adds carbon to the atmosphere.
The targets we all agree on - every country in the world except the U.S., Nicaragua, and Syria - will have targets under the Paris Agreement. So everyone knows what the targets should be, and then we can have a difference of opinion on exactly how these emissions will be reduced.
Many people say that this is not an easy issue, we cannot just say that this is how it is, it's not black and white. But I say that this is black and white. Either we stop the emissions or we don't. There are no gray areas when it comes to survival.
We're going to make sure there is a strong price on carbon right across the country, and we're hoping that the provinces are going to be able to do that, in a way, for themselves.
I'd like to see a little more action on the energy side of things. I've been pushing for some kind of a carbon tax for years, and it seems to me we've had lots of opportunities to do it.
