I share your concerns, especially when it comes to borders. More and more, the European Union is taxing carbon at the border.
Here, the official opposition does not support putting a price on pollution. We wouldn't be any farther ahead, though, since agricultural and other exporters would be hit by other countries' carbon taxes. Instead of paying a carbon tax here and reinvesting that money in our own economy, we would just be giving it to the Europeans and Americans. That's what our policy would look like when those measures came into force.
