First of all, it is the step code for energy. We'll get there, but with time. It's a question of continuous improvement.
I think you need to support the continued improvement process, and you can accelerate that by investing in the proper R and D with that condition established. You can use LCA to measure it—a life-cycle analysis or something—but what you want to do is make sure that everything that leads to that 2030, and maybe before, is measured, is quantified, and is better than the last iteration. That's what you have to do.
