The video above is a visual representation of the amount of carbon dioxide generated in New York City every day. The data is from a study conducted by Major Michael Bloomberg’s Office of Long Term Planning and Sustainability.

The visuals rely on the assumption that one ton of CO2 would fill a sphere 33 feet across – the large, blue orbs in the video. For artistic effect, each of the spheres emerge at the same spot in downtown Manhattan.

After the first hour of emissions (1:35), we can see the gas bubbles gathered at half the height of the Empire State Building. After a day (1:48), the bubbles have almost covered the building and its surrounding area. After a year (1:60), the entire island is buried. In this way, it is clear that the carbon footprint of New York City is enough to literally bury itself in unhealthy gas.

Carbon footprints can be generated by a person, family, building, organization, company, or country. The average carbon footprint per household in the US is 48 tons CO2 equivalent per year. The global average is around 10 tons CO2 equivalent per year.  The largest factors to this high carbon footprint are transportation, followed by housing, food, and goods. Of these factors, the largest contributor to carbon footprint is gasoline consumption. The most important part to remember is that for the average person, your carbon footprint is the total set of greenhouse gas emissions caused by your travels, purchases, and activities.

 

Removed from our daily lives, the largest hidden contributor to carbon footprint is the emissions generated by power sources. The United States has several techniques and fuels to supply electricity that each generates different amounts of carbon. Coal, oil, and natural gas understandably generate the highest amounts of CO2 equivalents per kilowatt hour. Nuclear, wind, and hydroelectric sources produce very little CO2 equivalents. In fact, wind and hydroelectric power only produce carbon emissions during construction and maintenance operations.

 

How can you reduce your carbon footprint? Consider the main categories:

 

Transportation:

  • Commit to driving less.
  • Consider purchase of a fuel efficient, hybrid, or electric vehicle.
  • Even better – use public transportation.

Housing:

  • Consider where your home’s electricity and heating come from, and investigate switching to a better source, such as geothermal.
  • Increase home insulation for the winter and use fans instead of air condition during the summer.

Food:

  • Buy local!
  • Avoid red meat, dairy, and seafood products.

Goods:

  • The larger the size of the product, the larger the footprint will be.
  • Glass is worse than aluminum – aluminum is highly recyclable.
  • Both glass and aluminum are preferable to plastic.
  • Use your own containers, mugs, cups, and utensils instead of disposables.
  • Consider purchasing used clothing.

 

What else can you do?

  • Purchase carbon offsets that can be used to fund research into sustainable development.
  • Purchase efficient equipment to reduce demand on energy sources.
  • Use less water – shorter showers, smart irrigation, limited lawn watering and car washing.

 

Overall, be conscious of the energy and materials that go into your activities and try to adjust accordingly. Each step you take is one closer to a cleaner tomorrow.

One Comment on “New York City’s Carbon Footprint

  1. We came across this video this week and we thought it is a great tool to visualise more clearly our carbon emissions. It is impressive the amount of carbon we produce in just one year. That’s why it is extremely important to try to reduce them, as you said.
