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.— Bill Gates
Valuable Co2 Emissions quotations
The climate system is constantly readjusting naturally in a large way - more than we would ever see from CO2. The CO2 kick [impact of CO2 emissions] is extremely small compared to what is happening in a natural way. Within the framework of a proper study of the sun-climate connection, you don't need CO2 to explain anything.
I think all countries need to aim to cut the CO2 emissions per person, taking account of externalities like imports and exports.
Even if you accept the theory of man-made climate change, wind turbines are a rotten way to reduce CO2 emissions, or to improve energy security.
CO2 emissions have been increasing, but the rise in air temperature stopped around 2001. Climate change is due in large part to naturally occurring oscillations.
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.
We face the gravest threat that civilization has ever confronted.
It's global in nature and requires a global solution. Increased CO2 emissions anywhere, whether from China or the United States or from one of the countries that is burning its forests like Brazil or Indonesia.
The European Union and environmental advocacy groups use global warming hysteria to advance their own special agendas. The European Union recognizes any significant reduction in CO2 emissions by the United States will significantly reduce its economic output, thereby bringing it closer to the inferior output of European nations.
I think any public policy that doesn't account for the fact that most CO2 emissions don't come from the United States, but they come from other countries, is a flawed policy. So let's not unilaterally tax our power, our people, to solve a global problem.
It's important to see things in perspective.
Automobile traffic is responsible for only 12 percent of total CO2 emissions. One should be able to point this out without being accused of changing the subject.
By using vertical space more effectively, you not only make more room for greenery but shorter commutes also mean less pressure on CO2 emission problems and by freeing up time now spent on unproductive commuter trains, people would have more options in their lives.
We need to reduce CO2 emissions in 10 to 15 years by 80 percent in order to avert catastrophic effects. ... What are catastrophic effects? A three degree centigrade climate change rise that will result in 50 percent species extinction.
Undoubtedly, at the moment, the major cause of CO2 emission is what happens in developed countries.
For me the two biggest issues are climate change and animal welfare/animal agriculture. And oddly enough animal agriculture is such a contributor to climate change. According to the United Nations, 25% of climate change comes from animal agriculture, so every car, bus, boat, truck, airplane combined has less CO2 and methane emissions than animal agriculture.
With this information, in light of the increasing human demands on vegetation, it is my personal opinion that capping CO2 emissions or reducing them to some prior level would be akin to 'biting the hand that feeds us.
I am not at all convinced that human emissions of CO2 are adding to global warming.... I remain to be convinced about the theory of anthropogenic global warming.
Does it make more sense to provide air conditioning or to limit CO2 emissions.
I vote for more air conditioning in these susceptible regions.
We can no longer completely avoid anthropogenic climate change.
At best, limiting the temperature rise to two degrees is just about possible, according to optimistic estimates. That's why we should spend more time talking about adjusting to the inevitable and not about reducing CO2 emissions. We have to take away people's fear of climate change.
It is in fact necessary to reduce CO2 emissions.
There is no reason why we shouldn't spend our vacations on (the North Sea island of) Sylt instead of in the Seychelles, or drive more economical cars - for the sake of preserving increasingly scarce resources if nothing else. But that won't enable us to stop climate change. As long as China, India and the United States continue the way they have been, what we Germans do is more or less irrelevant.
European carmakers pledged to reduce CO2 emissions by 25 percent from 1995 to 2008. We kept our word and reduced the value even more. This is not the result of short-term gimmickry. We decided years ago to develop the relevant models and engines, otherwise we wouldn't be able to offer them today.
Statistics compiled by the German Federal Motor Transport Authority highlight how successfully we have reduced fuel consumption. A few years ago, the CO2 emissions for the BMW brand were at well over 200 grams per kilometer. In 2009, that number was at 159 grams. This puts us below our direct competitors.
Naturally, we will continue to offer very powerful vehicles in the future.
Nevertheless, no other manufacturer has reduced the CO2 emissions of its fleet as substantially as the BMW Group.
What is the environmental policy of the Republican Party? When I ask that question, I get a blank stare, if I'm president of the United States, we're going to address climate change and CO2 emissions in a business-friendly way.
To reduce modern climate change to one variable, CO2, or a small proportion of one variable - human-induced CO2 - is not science. To try to predict the future based on just one variable (CO2) in extraordinarily complex natural systems is folly. Yet when astronomers have the temerity to show that climate is driven by solar activities rather than CO2 emissions, they are dismissed as dinosaurs undertaking the methods of old-fashioned science.
It seems that, notwithstanding the dramatic increases in manmade CO2 emissions over the last decade, the world's warming has stopped.
We don't know what's causing climate change on this planet.
And the idea of spending trillions and trillions of dollars to try to reduce CO2 emissions is not the right course for us.
