Yes. This is a significant challenge, I have to say.
The approach we've recommended in our guidance material is that in the absence of specific regulation or policy direction, we feel that it's nonetheless important to consider the greenhouse gas component as one of the environmental effects of concern. So we ask that the environmental assessments include analyses of the amount of emissions that will occur as a result of a project and compare them with any policies, regulations, or whatever form of direction exists in order to see whether or not they're acceptable.
