44 Ill. Adm. Code 500.1145
Environmentally Preferable Procurement
Section 500.1145 Environmentally Preferable Procurement
State agencies shall contract for supplies and services that
are environmentally preferable, as that term is defined in 30 ILCS 500/45-26.
If,
however, contracting for an environmentally preferable supply or service would
impose an undue economic or practical hardship on the contracting State agency,
or if an environmentally preferable supply or service cannot be used to meet
the requirements of the State agency, then the State agency need not contract
for an environmentally preferable supply or service. Specifications for
contracts, at the discretion of the contracting State agency, may include a
price preference of up to 10% for environmentally preferable supplies or
services.
