Action on environment 'cannot be postponed by financial crisis'

We will set up, alongside the states that wish to, Europeans and others, a tax on financial transactions. And I pledge that if that tax is created, part of this revenue will go to development... Some tell us that there is the economic crisis, the financial crisis, therefore the environmental issues and sustainable development can be postponed, put aside until the pressure (on the economy) stops. That is not my line of reasoning.
