To bridge the gap, advanced-country governments are leveraging their limited public funds to catalyze private-sector investment. At the same time, developing countries are rapidly increasing their contributions to green finance, with domestic clean-energy financing in non-OECD countries having surpassed OECD-country levels in 2008.
尽管如此，去年绿色投资规模只有2,540亿美元——这意味着每年的缺口将近7,500亿美元。为了弥补这一缺口，发达国家政府正在用有限的公共资金促进私人部门投资。与此同时，发展中国家对绿色金融的贡献正在快速增加，非经合组织国家的国内清洁能源融资规模在2008年便已超过经合组织国家。
