CARBON CALCULATOR

About the Calculator


This carbon footprint calculator has been developed to help members of the Oregon State University community understand the connection between their everyday actions and their carbon emissions. This is an important step in Oregon State University’s initiative to be carbon neutral by 2025.

This calculator is based on a calculator developed by Santa Clara University. For more information, please visit their website.

More information about the carbon emissions coefficients and calculations behind the calculator can be found here.

Why are there no solid waste questions? Direct disposal emissions from solid waste in Corvallis are negligible for a few reasons. About 10 miles North of Corvallis, the Coffin Butte landfill captures methane, which substantially reduces emissions associated with waste. Additionally, the OSU Corvallis campus composts and recycles enough tons of waste per year to counteract most of those emissions.

But what’s more important? While it’s great we have minimal waste disposal-related emissions, what really matters is purchasing and consumption – they have a significantly larger impact on your carbon footprint. So focus on reducing how much you consume, which will in turn create less waste! Buy used clothes and furniture, purchase food in bulk, print less, etc! More tips on reducing your footprint can be found in the “Next Steps” tab.

Now that you have your results, how can you reduce emissions? Fortunately, there are some simple choices most people can make to easily reduce their individual carbon emissions. Collectively, these contributions will help our community do its part.

Think about trying some of the following actions. Start with the easiest one or two, and challenge yourself to add additional actions each month.

  • Have a meat free day once a week.
  • Use a re-usable water bottle to drink tap water.
  • Carpool or take public transit for a few commute trips each week.
  • Buy second-hand clothing to minimize your supply chain emissions.
  • Purchase carbon offsets to account for airplane travel.
  • Wash your clothes in cold water and run large loads to save both water and energy.
  • Volunteer on campus and in the community! Plant trees, restore habitat, etc.
  • Swap out incandescent lights for LEDs or CFLs to see up to 83% energy savings! Use natural light whenever possible.
  • Turn off lights, TVs, and other electronics when they aren't in use.
  • Clean the lint trap in your dryer after every load.
  • Enable energy saving options on your computer and cell phone.

In addition to individual action to reduce carbon emissions, collective action is important! The OSU Sustainability Office has launched a Carbon Planning Toolkit to assist OSU departments in planning to reduce carbon emissions and strengthening climate awareness through education, research and outreach. You can participate by establishing a team within your department to implement the toolkit. For more information or help with the Toolkit, or day to day actions, contact the Sustainability Office at sustainability@oregonstate.edu.
