It generates 30 of greenhouse gas emissions.

Net greenhouse gas emissions down 82 percent in absolute tonnage.

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

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.

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.

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

CO2 emissions.

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.

The scientists tell us and they're only guessing that we've got to reduce greenhouse gas emissions by one half, and do it as fast as possible.

Industrial emissions cause air pollution.

Another action which was just taken independently by a shipping company itself was initiated because of concerns the shipping company had about greenhouse gas emissions with global warming.

They grow strawberries in their greenhouse.

I grow orchids in my greenhouse.

So, these are the greenhouse tents.

So it's a bit counterintuitive, but by collecting methane and burning it, which converts it into carbon dioxide, you're actually dramatically reducing the greenhouse gas emissions from the landfill.

CO2 emissions from the life cycle.

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

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.

My grandfather's greenhouse was also completely destroyed.

That's exactly what the Seawater Greenhouse produces.

A greenhouse effect. Everything is burning up.

(I don't know why there are pine cones in your greenhouse. Maybe the greenhouse is in a forest.)

And so I get to think of places that have nothing to do with Google's core business, but where we can really have a big impact in reducing greenhouse gas emissions.

CO2 emissions by four percent a year...

CO2 emissions are pouring into the atmosphere.

I'm not saying we shouldn't cut emissions.

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

So this technology, 3D printing, and new design rules really help us to reduce the weight, which is the biggest issue in aircraft design, because it's directly linked to greenhouse gas emissions.

Green carbon, which is the deforestation and agricultural emissions, and blue carbon together comprise 25 percent of our emissions.

I used to pick strawberries at his greenhouse.

And even with global warming if you can see these blue lines, the dotted line shows that even if emissions of greenhouse gasses stopped today, the next decades will see rising sea levels.

like slowing emissions, are intrinsically slow, because it takes time to build all the hardware we need to reduce emissions.

So we have this incredible presence today of agriculture dominating our planet, whether it's 40 percent of our land surface, 70 percent of the water we use, 30 percent of our greenhouse gas emissions.

It will occur without adding any more greenhouse gasses.

Into the small hall of the greenhouse. Please. You...

California emits only seven percent of U.S. CO2 emissions.

But what we're missing is also some other emissions

1 4 of the world's carbon dioxide emissions are from America its per capita emissions are also the greatest in the world.

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.
