Buying Guide: The Issues

Appliances consume lots of energy — often as much as one-third of an average household's entire energy budget. The main environmental impacts of appliances include:

  • Energy use, which can lead to the emission of greenhouse gases and other pollutants.
  • Water use, both the water required for operation and the effluent coming out of the appliance.
  • The release of ozone-depleting substances and greenhouse gases, particularly when older appliances are improperly handled after disposal.

Buying Guide: What to look for

  • Always opt for ENERGY STAR qualified appliances when possible.
  • For washers, go for “high efficiency” models. For dryers, look for an automatic shut off feature.
  • For refrigerator/freezer combos, choose top-mounted freezer models without through-the-door ice dispensers.

Buying Guide: What to avoid

  • Avoid older, used appliances — they are less efficient and may contain environmentally harmful chemicals.
  • Avoid top-loading washers that are not labeled “high efficiency.”
  • Avoid bottom-mounted, side-by-side, or French door refrigerator/freezer configurations.
  • Avoid hand-washing dishes — instead, use an efficient dishwasher to save time, money, energy and water.

Scoring Appliances

Overview

Environment scores are assigned to appliances by combining product-level environmental indicators (weighted at 75%) with company-level environmental indicators (weighted at 25%). Product-level scores incorporate the most significant aspects of the overall life cycle impacts of a product, but company-level scores are included to address product-level data gaps.

Product-level scores for this category are based on indicators of

  • Energy use, as measured by annual energy consumption or energy efficiency metrics, appliance type, and appliance features.
  • Water use, as indicated by appliance type and applicable certifications.
  • Certifications of energy and water efficient appliances.

Health scores are not assigned to appliances, because this product category is not associated with human health risks.

Social scores are based on company-level research. Product-level data on social performance are generally unavailable for this category of products, so GoodGuide relies on company-level social scores to characterize the performance of a product on this dimension.
