As global warming gets worse every year, more people are becoming concerned about their impact on the environment and their personal carbon footprint, which is the total greenhouse gas emissions that humans emit. Earth Hero was created by a global group of volunteers who decided to come together to address the climate emergency. You start by filling out a short survey to get a profile of where your carbon emissions come from, and then you can choose emission reduction goals based on relative global averages and recommendations from the Intergovernmental Panel on Climate Change.
