The nuclear approach I'm involved in is called a traveling-wave reactor, which uses waste uranium for fuel. There's a lot of things that have to go right for that dream to come true - many decades of building demo plants, proving the economics are right. But if it does, you could have cheaper energy with no CO2 emissions.

The struggle against poverty in the world and the challenge of cutting wealthy country emissions all has a single, very simple solution... Here it is: Put a price on carbon.

Al Gore

By fundamentally changing how we design the places and systems that enable our daily lives, we can slash emissions way beyond the immediate carbon savings - because our own personal emissions are just the tip of a vast iceberg of energy and resources consumed far from our view.

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.

Carbon zero simply means that the emissions you are releasing either are zero or balance out to zero.

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.

Alex Steffen

Achieving net zero carbon emissions by 2050, identifying treatments to diseases like cancer, and harnessing the power of robotics and artificial intelligence to support everyday tasks are all within our grasp. The first country that gives birth to these discoveries will change life as we know it.

The government believes that we will need to take the step of enshrining the Paris goal for net zero emissions in U.K. law. The question is not whether but how we do it.

EPA's Affordable Clean Energy rule (ACE), would restore the states' proper role under the Clean Air Act and our system of federalism. Our plan would allow states to establish standards of performance that meet EPA emissions guidelines.

Let's make sure that when companies make investments to reduce emissions that they're rewarded for that and encouraged to do more.

Are we better off if we displace jobs and investments to other countries and global emissions go up? I say no. Let's bring that production here and have less emissions globally because we can make things more efficiently and cleaner.

I believe those that produce the least emissions in autos will also be those who have the greatest success worldwide.

Angela Merkel

We have to ensure politically that what's doable can indeed by translated into law, but what's not doable mustn't become European law. Otherwise, the auto industry will work somewhere with higher carbon emissions - and we can't want that.

The methods that EPA introduced after 1970 to reduce air-pollutant emissions worked for a while, but over time have become progressively less effective.

The media when it focuses on climate change at all, does so in terms of carbon emissions and how to reduce them. Only rarely do our leaders advance arguments about adapting our environment and our economy to the effects of climate change that are already inevitable.

In the Labour Party we are absolutely united in our belief that shipping must define its 'fair share' of tackling climate change, and develop an emissions reduction plan for the sector.

Whilst the developed world may say it wants to see much greater commitment to reduce greenhouse gas emissions, this may only be politically feasible if there is strong support for adaptation measures in those countries at greatest immediate risk.

If we are serious about moving toward energy independence in a cost-effective way, we should invest in solar energy. If we are serious about cutting air and water pollution and reducing greenhouse gas emissions, we should invest in solar energy.

Bernie Sanders

For every $1 billion we invest in public transportation, we create 30,000 jobs, save thousands of dollars a year for each commuter, and dramatically cut greenhouse gas emissions.

There is no question that global warming will have a significant impact on already existing problems such as malaria, malnutrition, and water shortages. But this doesn't mean the best way to solve them is to cut carbon emissions.

Bjorn Lomborg

The best scientific evidence suggests temperatures are rising, and the best scientific evidence suggests man-made anthropogenic carbon emissions have some substantial thing to do with that. However, does that mean the trend will continue forever? We don't know.

Bret Stephens

If someone wants to do a carbon fee and someone else wants to do a cap on emissions or a renewable portfolio standard, we don't start labeling each other as more or less progressive.

Brian Schatz

The sun doesn't shine at night, and wind power is highly variable. To meet our emissions goals, we're going to have to grasp every arrow in the quiver, and nuclear is one of those arrows.

Burton Richter

Many are outspoken about the climate crisis, but conveniently ignore the fact that support for fossil fuels is not just incompatible with curbing emissions but dangerously counterproductive.

Caroline Lucas

With pollution from traffic a major source of greenhouse gas emissions, we should be building a transport and planning system that makes car-free travel for shorter distances the norm for the majority.

Caroline Lucas

It is impossible to talk about slowing climate change without talking about reducing CO2 emissions. Equally, it is impossible to talk about adapting to climate change without considering how we will feed ourselves. And it is out of the question that we can adapt agriculture without conserving crop diversity.

Cary Fowler

Under the Paris agreement, every one of the 147 signatories issues what is called an 'intended nationally determined contribution' (INDC), which amounts to a promise that the nation will take certain actions to reduce greenhouse-gas emissions by a certain date.

Charles C. Mann

I want a Mini-Cooper because it's fuel efficient, emissions efficient and all that stuff. It's small and better for the environment. I think that will be my next car.

The Clean Air Act of 1970 was designed to control air pollution on a national level by authorizing the development of comprehensive regulations to limit emissions.

Christine Todd Whitman

If Britain was to close down altogether overnight, then China would take up the slack of carbon emissions in two years. If America closed down, just the growth in China's emissions would replace America's emissions in 12 years.

Christopher Monckton

The greenhouse effect of carbon-dioxide emissions does produce gentle warming if it is not counteracted by unpredictable natural phenomena, but it cannot be measured directly against the volume of such emissions.

Conrad Black

Senator Hillary Clinton is attacking President Bush for breaking his campaign promise to cut carbon dioxide emissions, saying a promise made, a promise broken. And then out of habit, she demanded that Bush spend the night on the couch.

Craig Kilborn

As expanding economies continue to grow, the one source of energy that we can develop rapidly, cheaply and with next-to-no emissions is nuclear energy.

Craig Stevens

We actually all care about the environment, and most people believe in climate change and believe that mankind has something to do with that - how much is scientifically debatable, but there is some effect and we all have an interest in reducing carbon emissions, just having cleaner air, cleaner oceans. It's something we can get behind.

Dan Crenshaw

This is the way that I like to phrase it: we want to focus on 100% of the problem, and you can only focus on 100% of global emissions if you have technology that is exportable, clean, reliable, and cheap.

Dan Crenshaw

The environmental benefits of hydrogen are also outstanding. When used as an energy source, hydrogen produces no emissions besides water. Zero polluting emissions, an amazing advance over the current sources of energy that we use.

Dan Lipinski

Prominent scientists have become increasingly convinced that the connection between carbon emissions and rising temperatures is real, but skeptics have whole truckloads of studies to demonstrate the opposite.

David Ignatius

Many countries - as well as cities, states and provinces - are taking global warming seriously and are working to reduce emissions and shift to cleaner energy sources.

David Suzuki

We happen to believe that emissions going into the atmosphere are not good for us as humans or Mother Earth.

Dick Durbin

Reducing and removing greenhouse gas emissions spares our planet from the well-documented degradation that we are witnessing on a global basis.

Dick Durbin

Denmark, the Netherlands and Germany have detailed plans to cut their greenhouse emissions by 20 to 50 percent.

Donella Meadows

Alongside energy efficiency, renewables and abatement, I believe safe nuclear power, with manageable waste, can play an important role in reducing greenhouse gas emissions, as long as it is cost competitive with other low carbon generation.

Ed Davey

By leading on a strong emissions reduction target, the U.K. is persuading others on the need for member states to have the freedom and flexibility to develop their own energy mix to achieve these ambitious reductions.

Ed Davey

Climate change threatens the wellbeing of every person around the world and can only be addressed through a global response to reduce emissions.

Ed Davey

Smart cities are those who manage their resources efficiently. Traffic, public services and disaster response should be operated intelligently in order to minimize costs, reduce carbon emissions and increase performance.

Eduardo Paes

The pace of global warming is accelerating and the scale of the impact is devastating. The time for action is limited - we are approaching a tipping point beyond which the opportunity to reverse the damage of CO2 emissions will disappear.
