Think about it like this - the airline only operates that route because it knows it can make a profit from it. As a business class pax you're contributing a lot more of the profit incentive than the average economy pax and therefore have to assume more of the environmental impact.
In a more simple sense, you're taking up more of the available resource on the flight (cabin space & weight)
