Carbon penalty of material substitution again. The person who suggested that stainless steel might be a more environmentally thoughtful choice now points out further that stainless steel has a higher modulus than titanium, so its substitution by a stainless steel sheet of the same bending stiffness, rather than the same thickness, would make more sense. What is the ratio of carbon footprints per unit area when this comparison is made? The previous question has the data you need.
