We Designers are the ones with the wherewithal to understand the several connections between disciplines. It’s fair then that we ought to take the lead in making sure that products (and services) are designed responsibly. While Designers do have a responsibility towards justifying the fees they take from their clients, they have a much larger responsibility to the clients’ customers.
Design should be used to create the spark, not just to fight the fire.
The highest value comes from a designer’s work when products she designs can keep users delighted, safe and comfortable while simultaneously ensuring the planet is safe and well.
