Polyester polyols for use in low-VOC polyurethane compositions are disclosed. The polyester polyols are the reaction product of at least one aliphatic polycarboxylic acid, at least one alkoxylated polyalcohol having a functionality of 2.0 or greater, and one or more polyalcohols other than an alkoxylated polyalcohol. The polyester polyols can be formulated into polyurethane compositions to obtain a polyurethane having a low VOC content. The polyurethane composition is particularly suitable for polyurethane coating applications.
