Let me answer a little carefully.
I think it is true that you probably want to have a multi-faceted approach, but policy-makers should be careful about how much emphasis they place on non-pricing approaches, because they tend to be very expensive.
We wrote a report at the Ecofiscal Commission called “Supporting Carbon Pricing”, which was all about the kinds of non-pricing policies that complement a carbon price. Not all policies do. Some policies just don't work that well to complement a carbon price, and some do it at very high cost, but some do it well. I would encourage policy-makers not to just go for the multi-faceted approach, but to go for the low-cost package.
Our work suggests that a carbon price will be by far the most important element of that overall package.
