How a simple change - a nudge - is cutting coffee cup waste: A university campus has cut the use of disposable cups by reducing the cost of all drinks by 25p and charging a fine of 25p per drink to those who don’t bring a reusable cup. Changing from the previous incentive of ‘25p off’ for using a reusable cup to a 25p fine if you didn’t has nudged behaviour in the right direction.
