Bottom-up innovation adoption of green public procurement in the United States

Climate change and its outcomes are complex issues facing communities worldwide. Among policy options to address such issues, existing scholarship focuses mainly on regulatory policies. An innovative market-based policy option is green public procurement (GPP), which may induce private companies to voluntarily switch to more environmentally friendly products. The study examines the adoption and diffusion of GPP practices among local governments under the influence of state governments which may have distinct environmental policies and efforts. By drawing on data from an original national survey and supplemental sources and by employing a multilevel regression approach, this paper highlights GPP as an innovative, yet often overlooked, environmental policy option and strategic management tool. Results suggest a bottom-up, grassroots GPP adoption mechanism, emphasising local initiatives, strategic planning, and vision in sustainability advancement.
