in 2023, he reported the government wasn’t on track to meet its 2030 target (and thus not its 2026 interim target), finding that, “the measures most critical for reducing emissions have not been identified or prioritized” and “did not include a target or expected emission reductions for 95% of its measures.”
environment canada, he said, “had still not taken sufficient steps to improve the transparency and reliability of its economic and emission modelling” which “included overly optimistic assumptions, limited analysis of uncertainties and lack of peer review.”
in a follow-up report in 2024 demarco repeated his warning that the government program was insufficient to meets its own targets noting:
“we found that measures were being implemented too slowly to meet their intended emissions reductions in a timely manner” and “estimates of expected emissions reductions from their measures were often overly optimistic.”
“of the 20 measures (out of 149) we audited that were being developed or implemented by the federal government, only nine were on track, nine were facing challenges and two had significant barriers, such as facing delays in meeting milestones.”
demarco reported, “the recent decreases to projected 2030 emissions were not due to climate actions taken by governments, but were instead because of revisions to the data or methods used in modelling. the issue of the lack of transparency in the modelling continues to be an ongoing concern, which can undermine the trust and credibility in the reported progress.”

of 32 new measures added to the 149 previously announced by the trudeau government, demarco noted, “only seven …were new while three enhanced existing measures and 22 were existing measures that were already reported.”
regarding hydrogen, demarco said, “reduction estimates were overestimated” the “model applied to determine the potential of hydrogen was inadequate” and ‘assumptions were overly confident, and quality control on modelling was limited.”
