Politicians expect green public procurement (GPP) to serve as an environmental policy instrument. However, in order for GPP to work as an effective policy instrument, it is important to take into consideration potential suppliers' decisions to participate in the procurement process, the total number of bidders, and the screening of bidders with respect to mandatory green criteria. The aim of this paper is to empirically study GPP in this respect. The analysis presented here is based on data from Swedish cleaning service procurements that are unique in that they contain very detailed information on various environmental standards set by the contracting authorities. We find at best only a weak effect on supplier behavior, and this suggests that the use of GPP in this situation does not live up to its political expectations.
Under the Kyoto Protocol the European Union agreed to reduce emissions of greenhouse gases by 8 percent. The Burden-Sharing Agreement (BSA) redistributes the reduction target among the member states. The purpose of this paper is to evaluate the BSA. To determine if cost efficiency was considered, marginal abatement costs (MACs) are first calculated based on an estimation of the directional output distance function using country production data for 1990-2000. MACs, together with equity indicators, are then regressed on the emission change targets. The main conclusion is that both efficiency and equity were important aspects considered in the settlement.
