806 farmers were surveyed in Nicaragua, Costa Rica & Guatemala, using COSA® format to determine the socio economic and environmental impact of coffee certification. 40 farmers from each certification (organic, fair trade (FT), Rainforest Alliance (RA), CAFE Practices (CP) and Utz Certified) were interviewed and compared with 80 non-certified farmers on each country. Results showed better performance of environmental indicators (Carbon footprint) in organic farms. Economic impacts were affected by farm altitude and size. RA and CP certified farms were in general larger farms (> 10 has), with higher production costs and but higher productivity resulting in greater income per hectare. Utz, Organic and FT were smaller farms, with lower production costs and lower productivity. Guatemala did not show differences in certified vs conventional sales prices for any seal. Although organic farms had on average the best coffee price they had one of the lowest income due to low productivity.
