Consumer concerns over ethical and environmental issues associated with cocoa production are a potential threat to its position. These concerns have given rise to certification. Certification dictates the way cocoa can be produced and consequently affects producers�?? incomes and environmental services. The expected profitability, yield, and environmental impact of Rainforest Alliance certified shade-grown cocoa production (RA-Cocoa) is estimated and compared to an extensive shaded production system (Ext-Cocoa) and an intensified full sun production system (High-Tech). Ext-Cocoa represents most cocoa production systems in Ghana, while High-Tech is promoted by the government as a tool for attaining its target output of 1 million tons. Under the baseline assumptions High-Tech was the most profitable; RA-Cocoa generated positive returns, while Ext-cocoa was a break even proposition. Simulation of different policy scenarios did not affect the rank order of the baseline outcome. The Ext-Cocoa yield was 28% of the RA-Cocoa yield, which was 78% of the High-Tech yield. The environmental services maintained at the plot level of RA-Cocoa production system are greater than those of the High-Tech production system. However, the 228,000 ha of additional forest land required to produce 1 million tons with RA-Cocoa questions which system would impact environmental services the least
