We don't have a figure right now. We're desperately looking into the matter right now, but it's hard to overlook. When you talk to transportation companies, they are charging more to transport anything.
Frankly, because we are a large country with only 40 million people, you have to look at logistics. Our logistical system is not that efficient. It's very costly and it requires more energy. When it requires more energy, the carbon tax is actually added to that. That's why we need to look at the compounding effect of the carbon tax across the supply chain. Right now, we haven't seen anything looking at that issue.
