Catalyst for Improving the Environment

Why We Did This Review

We initiated this evaluation to
independently test ENERGY
STAR products to determine
whether their energy-efficient
performance complied with the
ENERGY STAR program's
required specifications.

Background

The U.S. Environmental
Protection Agency (EPA)
established the ENERGY
STAR Labeling Program as an
innovative approach to
environmental protection.

More than 2,400 manufacturers
and over 40,000 individual
product models across
60 product categories are
ENERGY STAR qualified.
In 2007, EPA reported that the
ENERGY STAR program
helped Americans save
180 billion kilowatt-hours,
about 5 percent of U.S.
electricity demand, and
prevented the emission of
40 million metric tons of
carbon equivalents of
greenhouse gases.

ENERGY STAR Program Integrity Can Be
Enhanced Through Expanded Product Testing

What We Found

Almost all of the ENERGY STAR products in our test sample met, and in most
cases exceeded, the program's performance standards. However, selected non-
ENERGY STAR products performed comparably to, and in some cases better
than, ENERGY STAR products. That level of product performance affects the
ENERGY STAR label's image as a trusted national symbol for environmental
protection through superior energy efficiency.

In addition, the performance results of ENERGY STAR and non-ENERGY
STAR products call into question the assumptions used to calculate energy
savings and greenhouse gas reductions attributed to this program. Without an
enhanced testing program, including the testing of non-ENERGY STAR
products, EPA cannot be certain ENERGY STAR products are the more energy-
efficient and cost-effective choice for consumers.

What We Recommend

We recommend that EPA verify estimated energy savings and greenhouse gas
reduction calculations using a market-based performance-testing program that
includes testing non-ENERGY STAR products.

We also recommend that EPA revise the ENERGY STAR Website to include the
established standard alongside qualifying product performance data and to
provide a summary listing of the highest performers.

The Agency disagreed with our conclusions but concurred with both
recommendations.
