Addressing these barriers requires an integrated approach across environment, economic and social domains, and often close coordination among different levels of government. Clear, stable and credible long-term environmental, energy, transport and infrastructure policy signals are important drivers of investment and innovation (Kaminker, C., et al, 2013; Corfee-Morlot, J., et al, 2012; Criscuolo, C. and C. Menon, 2014; OECD, 2012; and OECD, 2013b). In addition, barriers to investment and innovation can often be addressed with revision to existing policy, regulation and tax settings (Kaminker, C., et al, 2013).
