The recommendation is to replace line 16 on page 4 to add in “regardless of whether the effects are within the control of a proponent, that would permit the carrying out, in whole or”, and then it says “in part”.
That clarifies the best practice that all potential effects of a project are assessed, whether or not the proponent directly controls them. There are a good number of legal organizations that have proposed this, including Ecojustice, Nature Canada, and West Coast Environmental Law.
