The parent is simply pointing out that all consumption taxes are regressive. A CO2 tax by itself is a tax on the poor, especially the rural poor who have longer commutes and are more dependent on automobile travel.
A CO2 tax is only fair if it's paired with progressive tax breaks in other areas and/or subsidies for transition to renewable energy. An example would be a progressive subsidy for electric vehicle purchases and for upgrades to CO2-heavy (coal) electricity generation infrastructure in poorer areas.
