A brand-new online environmental tool from Low Impact Living, the Impact Calculator, measures the many footprints of a household’s lifestyle. With it, families can assess their specific carbon, energy, water, trash, wastewater and stormwater-runoff amounts. Then, by entering the Zip code and home size, it encapsulates in one number the overall environmental footprint compared with a typical home in the region, suggests green home and lifestyle projects and saves a profile, along with project notes, for future reference.
