Future having the option to include a legal company investment plan for CO2 emissions, might be ideal (e.g. social responsibility program e.g. reforesting volunteering, cleaning volunteering, , non catalogue expense items, social responsibility registered authorized donation companies, sustainable composed items, etc...)

Not having a CO2 emission investment plan for the purpose to document efforts of CO2 reductions efficiencies and/or the option to replace conventional items to sustainable or friendly green environment items), user might potentially track CO2 emission reductions plans outside the system.
