About TerraPass

The TerraPass story

TerraPass is the brainchild of Dr. Karl Ulrich at the University of Pennsylvania. Along with 41 of his students, Karl launched TerraPass in October 2004 as a way to help everyday people reduce the climate impact of their driving. Within its first year, TerraPass registered over 2,400 members, reduced 36 million pounds of CO2, and earned countless national press and blog articles.

Soon after this, TerraPass expanded its focus to address greenhouse gas emissions from other important sectors, such as flying and energy consumption.  Around the same time, we began reaching out to corporations and institutions (such as universities) that wanted to take responsibility for their respective impact on climate change.

Since then, TerraPass has helped more than 1,000 businesses and other institutions, as well as hundreds of thousands of individuals, take responsibility for their impact on the climate.  This has resulted in implementation of dozens of renewable energy and greenhouse gas destruction projects that in aggregate have reduced greenhouse gases in our atmosphere equivalent to billions of tons of carbon dioxide.  Click here to see our latest Climate Action Update.

Who we are

TerraPass is a multi-disciplinary team of individuals dedicated to the fight against climate change.  Our mission is to provide the resources necessary for companies and individuals to understand and take responsibility for their climate impact.  We do this in a number of ways:

  1. We provide educational tools and resources such as online carbon footprint calculators.  We also help businesses and institutions prepare more detailed or complex carbon footprint analysis;
  2. We help create, implement, and operate customer-funded emissions reduction projects at facilities such as dairy farms and landfills.  Learn more about our projects here;
  3. We work with businesses and institutions to develop custom renewable energy solutions for their operations.


But TerraPass isn’t just us it’s you too, because we wouldn’t be able to do what we do without the support of others who also want to take action on climate change.
