Greenhouse gases trap heat and make the planet warmer, contributing to the problem of global climate change. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.
Since 2007, PDCCC has reduced its total greenhouse gas emissions from energy by approximately 22%. Emissions result directly from the campuses consumption of natural gas and propane as well as indirectly from the consumption of electricity generated by fossil fuel sources.
These avoided emissions, about 351 Metric Tons of CO2 per year, are equivalent to:
- The emissions savings of taking more than 71 passenger cars off the road per year.
- The amount of CO2 absorbed annually by 284 acres of forest.
- The emissions attributed annually to 17.5 single-family homes.
