Globalism as an ideology is distinct from globalization of trade. Globalists would argue for expansive supranational regulatory controls. Migration and alleged environmental concerns are typical rationalizations for their expanding powers. The distinction is better understood as between a set of liberal, laissez-faire trade policies and an emerging illiberal supranational regulatory state.
Specifically when you say:
>Globalism fixes the amount of pollution globally to the market optimum where presumably an environmentalist wants to control pollution using some other system than markets.
We can observe that the Globalist organizations regard not just pollution, but carbon consumption to be something which markets cannot be trusted to manage. Instead they propose top-down regulatory management on a supranational level.
