A Swedish-based think tank is launching a new credit card in collaboration with the UN Climate Change Secretariat and Mastercard that will give individuals a means to lower their carbon footprint the hard way. The credit card will cut off your spending — actually disapprove a transaction — because you have reached your carbon limit for the year. According to Fast Company, each person’s limit is based on a country-specific calculation of how much carbon an individual can “emit” and still stay on track with the 2030 goal to cut emissions in half. Mathias Wikström, one of the co-founders, said of the inspiration for the card, “I mean, people will react to it like, ‘Oh, so you want me to stop spending?’ No, not necessarily. I want you to start understanding.” Talk about putting your money where your mouth is.
