Have you ever been given a choice to offset your carbon footprint while on a flight? I came across that question a few times, at times when I did not care much about the planet. Like many I suppose, I thought spending time and effort towards my work, health, and family were of more significance, ignoring the fact that I had a responsibility towards the planet where I was living. During a recent trip to Hong Kong from Singapore, however, when I am more conscious about my lifestyle choices, something struck my mind related to carbon offsetting.
