CO2e emissions are equivalent emissions of all the greenhouse gases and particles that cause warming and converted to CO2.

We're greenhouse gases. You ain't going nowhere.

It generates 30 of greenhouse gas emissions.

Net greenhouse gas emissions down 82 percent in absolute tonnage.

These greenhouse gases trap heat near the earth through a naturally occurring process called the greenhouse effect

This is a U.S. statistic about the impact of greenhouse gases.

And we know that levels of greenhouse gases are rising too.

Five percent of our greenhouse gases are produced by mowing our lawns.

H is for habitat destruction, including climate change forced by greenhouse gases.

Scientists now believe that the greenhouse effect is being intensified by the extra greenhouse gases that humans have released

Greenhouse gases are a byproduct of this process, and are released through waste.

As I said, 18 percent of greenhouse gases are attributed to livestock production.

What is the exact relationship between levels of greenhouse gases and planetary temperatures?

But don't we already know what we need to know about greenhouse gases?

This is what the U.K. government target on carbon and greenhouse emissions looks like.

The big opportunity to reduce greenhouse gas emissions is actually in urbanizing the suburbs.

It's the single largest emitter of greenhouse gases of any human activity in the world.

Now, many of the people who participate in Earth Witness would focus on ecological problems, human caused or otherwise, especially environmental crimes and significant sources of greenhouse gases and emissions.

Usually when we think about the atmosphere, we think about climate change and greenhouse gases, and mostly around energy, but it turns out agriculture is one of the biggest emitters of greenhouse gases too.

The oil produced from either method produces more greenhouse gas emissions than any other oil.

Eighteen percent of our contribution to greenhouse gas emissions worldwide is the result of deforestation.

Steel represents about three percent of man's greenhouse gas emissions, and concrete is over five percent.

You only have a limited amount of money, you want to reduce greenhouse gases, so you want to apply the dollars in ways that reduce greenhouse gases the most while creating the most employment possible for that investment.

But they're also materials with very high energy and very high greenhouse gas emissions in their process.

In my particular job, I'm trying to have the biggest impact in terms of reductions of greenhouse gases.

Of course, since the greenhouse gases are still building up, it takes more and more ice each time.

Noble gases

Because California was the first state in this country to mandate 25 percent reduction of greenhouse gases by 2020.

So what we're doing is, we're taking the most concentrated greenhouse gas sink, twice as much greenhouse gases are sequestered in the boreal per acre than the tropical rainforests.

CO2 emissions.

If those plants die, they decompose, and tiny microorganisms break down those carbohydrates and again, release greenhouse gases as a byproduct.

So if you think about that, eight percent of our contribution to greenhouse gases today comes from those two materials alone.

It's a greenhouse.

Almost half of our greenhouse gases are related to the building industry, and if we look at energy, it's the same story.

It records the annual rise and fall of greenhouse gases and temperatures going back before the onset of the last ice ages.

And that is now what we're trying to do, and working with this large cities group to fight climate change, to negotiate huge, big, volume deals that will enable cities which generate 75 percent of the world's greenhouse gases, to drastically and quickly reduce greenhouse gas emissions in a way that is good economics.

Although much remains to be learned about global warming, many organizations advocate cutting greenhouse gas emissions to reduce the impact of global warming.

Now, even lower emissions!

It's about energy emissions.

limit on carbon emissions.

And with our hyper consumption of those animals producing greenhouse gases and heart disease, kindness might just be a bit of a red herring.

Liquids are heavier than gases.

Let's start focusing on gases.

Meanwhile, readings taken from ice cores show that the greenhouse gases carbon dioxide and methane have hit their highest value in the last 420,000 years.
