The Problem

Mercury thermostats can be a major source of mercury contamination in the environment. Mercury is a dangerous neurotoxin. It does not break down in the environment and it bioaccumulates in the tissues of fish, which are then consumed by people. One gram of mercury can contaminate a 20-acre lake. Mercury thermostats, each containing about 3 grams of mercury, have been phased out in California but are still found in many homes and businesses.

Supporting Thermostat Stewardship

In 2008, CPSC and the California Sierra Club co-sponsored AB 2347, the Mercury Thermostat Collection Act. This was the first extended producer responsibility bill to become law in California. The nonprofit Thermostat Recycling Corporation (TRC) was formed to serve as the stewardship organization and to develop a convenient take-back program. Under the law, heating and air conditioning (HVAC) wholesalers must accept mercury thermostats from the public free-of-charge, and contractors who remove mercury thermostats must recycle them.

In February 2013, CPSC and our partner organizations submitted comments on the proposed regulations to implement the new law, which were adopted in May 2013. CPSC and our allies issued this press release on the final rulemaking.
