Purchases of socially responsible products are the lowest in Australia (29.1%), according to the report, although it said consumers in Japan (20.9%) are least likely to consider whether a merchant acts "ethically" when shopping.
Across the region, an average of 64% bought products based on fair trade principles, 58.8% bought products which are environmentally friendly while 47% purchased products that donate a portion of their sales to a good cause.
Chinese shoppers (68.3%) are the most likely to buy products from a merchant they consider to be ethical, followed by consumers in Thailand (68%) and Malaysia (64.3%).
Commenting on the report, Georgette Tan, group head of communications at MasterCard Asia/Pacific, said: "People in emerging markets are increasingly concerned about the impact of rapid growth on the environment and society.
"It is not surprising that they are more likely to think of the supply chain and ethics of a merchant when deciding what to buy and where to shop."
