    Sec. 45-26. Environmentally preferable procurement.
    (a) Definitions. For the purposes of this Section:
        (1) "Supplies" means all personal property, including
    
but not limited to equipment, materials, printing, and insurance, and the financing of those supplies.
        (2) "Services" means the furnishing of labor, time,
    
or effort by a contractor, not involving the delivery of a specific end product other than reports or supplies that are incidental to the required performance.
        (3) "Environmentally preferable supplies" means
    
supplies that are less harmful to the natural environment and human health than substantially similar supplies for the same purpose. Attributes of environmentally preferable supplies include, but are not limited to, the following:
                (i) made of recycled materials, to the
            
maximum extent feasible;
                (ii) not containing, emitting, or producing
            
toxic substances;
                (iii) constituted so as to minimize the
            
production of waste; and
                (iv) constituted so as to conserve energy and
            
water resources over the course of production, transport, intended use, and disposal.
        (4) "Environmentally preferable services" means
    
services that are less harmful to the natural environment and human health than substantially similar services for the same purpose. Attributes of "environmentally preferable services" include, but are not limited to, the following:
                (i) use of supplies made of recycled
            
materials, to the maximum extent feasible;
                (ii) use of supplies that do not contain,
            
emit, or produce toxic substances;
                (iii) employment of methods that minimize the
            
production of waste; and
                (iv) employment of methods that conserve
            
energy and water resources or use energy and water resources more efficiently than substantially similar methods.
    (b) Award of contracts for environmentally preferable supplies or services. Notwithstanding any rule, regulation, statute, order, or policy of any kind, with the exceptions of Sections 45-20 and 45-25 of this Code, State agencies shall contract for supplies and services that are environmentally preferable.
    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.
