Everyone’s definition of a “green” product varies across factors incorporating ethical, organic, fossil fuel free, local production, energy efficiency and more. Your own definition will be a weighted mix of these factors. You might eat only organic food but not be willing to restrict your self to garments made from organic cotton. Ensuring your personal care products aren’t tested on animals might take priority over the water efficiency of your washing machine.
A number of organisations define standards and maintain certifications of products across these areas. They’re a great quick guide to finding products that meet your own personal “green” criteria.
