The state of Missouri is attempting to change its green cleaning legislation from encouraging green cleaning in K-12 schools to requiring it.

The Missouri House of Representatives introduced House Bill 1602 in February, which would mandate all school districts to purchase cleaning supplies approved by Green Seal, EcoLogo and the EPA’s Design for the Environment program. The legislation would also apply to “environmentally sensitive” cleaning equipment.

Under the proposed legislation, districts would be able to annually opt out of the program if they could prove that transitioning to a green cleaning program would not be economically feasible.

The state’s current legislation was passed in July 2008 and currently outlines green cleaning guidelines and specifications and recommends — but not requires — purchasing criteria and best practice policies.
