High school students can investigate the link between everyday actions at their high school, greenhouse gas emissions and climate change. Using EPA’s Climate Change Emission Calculator Kit (Climate CHECK) students can learn about climate change, estimate their school’s greenhouse gas emissions and conceptualize ways to mitigate their school’s climate impact. Students gain detailed understandings of climate-change drivers, impacts, and science; produce an emission inventory and action plan; and can even submit the results of their emission inventory to their school district.
