One example would be from our report on carbon pricing, in which we identified some weaknesses in, essentially, the fairness between the industrial price and the retail or consumer price, especially as regards small businesses and indigenous peoples. Those are the examples we gave there. An increased stringency on the industrial side of the carbon pricing may have an important impact. That's one example but, again, it's a choice for government to make as to whether they want to increase the stringency.
Of course, regulations are another example of where stringency can be increased and, essentially, ambition be ratcheted up, as experience is gained with the application of regulations. Both carbon pricing and regulations are areas where stringency could be included, if that's the will of the government.
