-It's not a moral issue...
More than 400 taxis in Beijing are now powered by electricity rather than fuel and liquid petroleum gas. By
the end of 2012, the city will have 5,000 electric vehicles on its roads in a bid to reduce carbon emission.
"But is eco-friendliness always a boon? When University of Toronto researchers Nina Mazar and Chen-Bo Zhong recently looked into this, they found that under certain circumstances, green products can license us to act immorally.
Through a series of experiments, Mazar and Zhong drew the following distinction between two kinds of exposure to green: When it’s a matter of pure priming (i.e., we are reminded of eco products through words or images), our norms of social responsibility are activated and we become more likely to act ethically afterwards. But if we take the next step and actually purchase the green product (thereby aligning our actions with our moral self-image), we give ourselves the go-ahead to then slack off a little and engage in subsequent dishonest behavior."
