That's an excellent question. Unfortunately, I don't know what is meant by a risk-based approach. What kind of risk is enough to trigger a lawsuit? Unfortunately, this information is often not available. Unless you're the people who make and implement policy, you can't know what their intentions are behind it.
That being said, I come back to my point. I think the key to reducing the commission of environmental offences is prosecution and enforcement. Since there are few measures in place to enforce the act, there are areas that avoid enforcement. Clearly, the system isn't doing its job of deterring offences, so choices have to be made, but I think we need to move away from warnings. There are a lot of warnings, and very few prosecutions are brought.
For example, in 2016-17, 2,721 warnings were issued and 26 criminal investigations were initiated. So we need to work on that. As I said, administrative monetary penalties fulfill some of the objectives of enforcement, such as promptness, but also the application of penalties.
