Determinants of environmentally-oriented government procurement in Singapore

Purpose: This study aims to identify the critical determinants of environmentally-oriented government procurement in Singapore. Research approach: Through extensive literature review, this study has identified four determinants of sustainable procurement: integrated product attributes (IPA), waste management (WM), organisation systems and processes & policies (OSPP) and organisational values (OVAL). A multiple regression using SPSS is employed to assess the relationships between the four determinants of environment-oriented government procurement practices. Findings and Originality: Results of the correlation analysis show that all six correlations among the four determinants are positive and significant which broadly support that the determinants should be implemented in combination. Although, the coefficients of correlation between environmentally-oriented procurement practices and each of the four determinants were positive and significant, the results of multiple regression analysis showed that only organisation systems and processes & policies (OPSS) and organisational values (OVAL) have positive and significant relationships with environmentally-oriented practices. Research impact: This study contributes valuable insights into the determinants of sustainable procurement in public organizations in Singapore. Both managers and researchers should find it useful that decisions to procure environmentally-oriented products are influenced mainly by organisation systems, processes and policies and organisational values.
