New York City’s greenhouse gas emissions as one-ton spheres of carbon dioxide gas

In 2010 New York City added 54 million metric tons of carbon dioxide (equivalent) to the atmosphere, but that number means little to most people because few of us have a sense of scale for atmospheric pollution.

Carbon Visuals ( and Environmental Defense Fund ( wanted to make those emissions feel a bit more real – the total emissions and the rate of emission. Designed to engage the ‘person on the street’, this version is exploratory and still work in progress. Mayor Bloomberg’s office has not been involved in the creation or dissemination of this video.

NYC carbon footprint:

54,349,650 tons a year = 148,903 tons a day = 6,204 tons an hour = 1.72 tons a second

At standard pressure and 59 °F a metric ton of carbon dioxide gas would fill a sphere 33 feet across (density of CO₂ = 1.87 kg/m³: If this is how New York’s emissions actually emerged we would see one of these spheres emerge every 0.58 seconds.

Emissions in 2010 were 12% less than 2005 emissions. The City of New York is on track to reduce emissions by 30% by 2017 – an ambitious target.

Tracking Our Footprint follows families in the United States, India and Cameroon to examine how energy is used in three economies: industrialized, emerging, and developing. This documentary explores options to manage carbon emissions from energy use while providing adequate access to energy for the worlds growing populations.

Imagine that aliens landed and gifted us a clean, limitless energy source. And instead of killing each other over this technology, we decided to immediately transform the world into a carbon-free society. This wonderous source would power our homes, industries, cars and planes, and humanity’s annual rate of carbon pollution would almost instantly fall to zero. So if we kicked our carbon addiction tomorrow, what would that mean for global warming?

What is a Carbon Footprint

Learn what a carbon footprint is and how that relates to climate change. Be Conscious. Make an Impact. Be Rewarded.

Greenhouse gases absorb heat when they interact with sunlight, they are the reason earth has a climate.

Your carbon footprint is the total of all of the greenhouse gas produced by what you do and by the energy spent making the things you buy.

The place you live…
The car you drive…
the clothes you wear…
the food you eat…
even that cup of morning coffee…
all consume energy…

And they all add to your carbon footprint

Just like the water cycle…
there is a natural carbon cycle present in our atmosphere.
Carbon is the building block of life on earth…
and there is a natural carbon cycle between animal life,
and oceans
which is known to have kept carbon in balance for hundreds of thousands of years.

This cycle has been known to be in balance for over 800,000 years
With natural atmospheric carbon ranging between 180 and 280 ppm

Carbon levels relate very closely to global temperatures as you can see from the data over the same time period.

However, since the Industrial Revolution,
human activity has dramatically increased the amount of carbon being released…
and it is more than the natural cycle can handle…
meaning the carbon cycle is becoming increasingly out of balance.

If our emissions continue to climb, our temperatures are sure to follow. The good news is we can take action to make changes because we know why this is happening.

This is happening because of our use of fossil fuels
Fossil fuels contain carbon that has been outside of the carbon cycle for millions of years.
So every time we use fossil fuels, we are increasing the amount of carbon that is in the active carbon cycle.

The impact: a buildup of Greenhouse Gas leading to climate change
