We study how government green procurement policies influence private-sector demand for similar products. Specifically, we measure the impact of municipal policies requiring governments to construct green buildings on private-sector adoption of the US Green Building Council's Leadership in Energy and Environmental Design (LEED) standard. Using matching methods, panel data, and instrumental variables, we find that government procurement rules produce spillover effects that stimulate both private-sector adoption of the LEED standard and investments in green building expertise by local suppliers. These findings suggest that government procurement policies can accelerate the diffusion of new environmental standards that require coordinated complementary investments by various types of private adopter.JEL Codes: L15, Q58, Q55, O33.Keywords: Public procurement, green building, quality certification, environmental policy. * We thank Melissa Ouellet and Mark Stout for their outstanding research assistance and Tom Dietsche for providing and interpreting data from the US Green Business Council.

The US Environmental Protection Agency and the European Union, for example, have developed environmentally preferable purchasing guidelines for goods ranging from paint, paper, and cleaning supplies to lumber and electricity. Various state and local governments have taken similar steps.
1These procurement policies often have the stated goals of encouraging cost-reducing innovation among suppliers and spurring private demand for green products (Brander et al. 2003;Marron 2003). The European Union, for example, justifies its environmental procurement policy not only on the basis of leveraging government demand to "create or enlarge markets for environmentally friendly products and services" but also on the basis of stimulating "the use of green standards in private procurement" (Commission of the European Communities 2008: 2). To date, there has been little evidence on whether these targeted government procurement policies produce the intended spillover effects. This paper provides some initial evidence by measuring the impact of municipal green building procurement policies on the private-sector adoption of green building standards.We examine whether green building requirements that apply only to municipal buildings accelerate the use of green building practices b...
