The OECD is advocating for increased taxes on international businesses, cross-border investments, and global levies on wealth and energy generation.

Success in corporate tax harmonization has led the OECD to propose new global minimum taxes on wealthy families and potential cartelization of personal income tax systems.

The OECD is expanding its climate policy work, aiming to enforce global climate standards through extraterritorial taxes or tariffs.

The organization's mission is shifting towards more aggressive global governance proposals, which could limit market competition and increase barriers to cross-border investment.

The OECD's success in creating a new international tax framework could inspire similar efforts in other policy areas like personal income taxes and carbon mitigation measures.

If the global tax deal stalls, it could temporarily set back the push for greater international standardization.
