Although it’s important to change your habits to cut your carbon dioxide footprint, you can also use your money to reduce CO2. This Earth911 quiz asks you about two financial instruments that let you pay for the sequestration of CO2 directly or buy clean energy: carbon offsets and renewable energy certificates (RECs). Test your knowledge of how these financial tools can help you reduce your carbon footprint.
Making smart sustainable choices requires practice. Earth911’s weekly sustainability quiz helps you hone your ability to recognize earth-friendly products and services. Through your daily choices — from transportation mode to purchases to waste disposal — you can make a positive difference.
