This includes emissions trading through voluntary and compliance market credits for Reducing Emissions from Deforestation and Forest Degradation (REDD) and water and pollution trading schemes. For example, environmental pollution quotas for nitrate, phosphorus and/or salt discharges can be traded by low polluters to high polluters for whom the buying of permits is cheaper than installing anti-pollution technology. Despite initial difficulties, projects like the Clean Development Mechanism (CDM) where carbon credits can be generated through afforestation and sold in existing markets indicate a possible way forward on this. The World Bank BioCarbon Fund will purchase emission reductions of 600,000 tC02eq, while the Prototype Carbon Fund purchased 1.3 million tC02eq under a separate agreement in 2002. In addition to the World Bank and Moldsilva (the Republic of Moldova's Forestry Agency), 384 local councils represent the participating rural communities.
