Greenhouse gases (GHG) are chemical compounds that have always been in our atmosphere and help regulate the temperature of our planet. This includes carbon, methane, etc. These gases are what has allowed life to exist and thrive on this planet. These gases and their amount are directly connected to the temperature and overall climate of the Earth.

Since the 1880s humans, through the burning of fossil fuels and changes in land use patterns, have put significant quantities of GHG into the atmosphere. This is causing an enormous shift and change in the Earth’s climate and the Earth’s ability to support a healthy, safe planet and habitat for people. To address this vulnerability and the impacts of climate change we need to reduce the emissions of greenhouse gases.  Addressing and reducing GHG emissions requires a holistic approach because of how embedded carbon and fossil fuels are in all aspects of society. Every part of society needs to reduce emissions and look to decarbonize.
