What else can I do after purchasing offsets?
Energy is the major driver of climate change at this point, but only because energy usage is pervasive throughout the entire global economy. Your food, your computer, your phone, and even the books you read were all created and brought to you using some form of energy (most likely from fossil fuels). Therefore limiting the usage of energy, and energy-intensive goods, is the single greatest thing an individual can do. On top of using less energy in general, actions such as using super efficient lighting, appliances and vehicles, and purchasing locally sourced items over goods shipped overseas can collectively have a large impact.
