Mentioning how much carbon dioxide emissions a company has reduced (remediation) is positive, but the reader will not know how positive (or potentially still negative) if the writer does not evaluate:
a) how significant of an impact the carbon dioxide emitted has on the environment.
b) comparing it to the industry average, or to its main competitors.
"In 2019, CN’s non-renewable energy consumption represented 21,714,241 MWh (megawatt-hours) which is a 15% increase from 2016. The company’s renewable energy sources have increased only slightly: 404,102 MWh in 2016 to 464,390 MWh in 20195;p5 making CN’s renewable energy consumption 2% of its total consumption. This is only 1% higher than its competitor, Canadian Pacific Railway which reported its energy consumption at 11,384,000 MWh in 20186;p118. Of that, only 157,000 MWh was represented by renewable fuels7;p118."
