The amount of CO2 emissions a human makes or even an average family makes pales in comparison to the emissions companies create. It was all advertising propaganda to reduce corporate accountability.
This is simply incorrect. CO2 emissions from a single passenger vehicle alone are ~5 tons/year (this is tailpipe missions only), while per capita emissions for EU/US citizens are between 5 and 15 tons/year.
So invididual transport alone (not even counting indirect emissions from vehicle construction, road infrastructure etc.) is already significant.
What fraction of emissions would you blame on corporations alone (which corporations)?
