This paper argues that new, moreautomatic fundraising approaches promise to be moreeffective than the traditional approach in raising adequateand predictable resources to help developing countriesrespond to global environmental challenges. An annual greenplanet contribution of United States (U.S.) 2 dollars leviedon some polluting activity and paid by applicable individualcitizens of developed countries will raise about twice theamount of resources currently available from bothmultilateral and bilateral sources for global environmentalmeasures in developing countries. The following analysisdiscusses why such a fund-raising approach for protectingglobal commons in developing countries will be superior tothe existing mechanism and why it holds the promise ofsecuring adequate and predictable resource flows in thecoming decades. The present analysis builds on recentexperience with new market-based approaches to domesticenvironmental policy-making in Organization for EconomicCo-operation and Development (OECD) countries. The paperdiscusses various options for levying a global environmentalcharge or user fee with respect to such factors as ease ofimplementation, political acceptability, and fund-raisingpotential. It concludes that a personal green planetcontribution levied annually with car registration renewalmay be the most promising, albeit not the only, option worth considering.
