That's too sweeping a view to take of the world. In developing nations, for instance, environment very often takes a back seat to 'development', whereas in industrialised nations the political will to make hard decisions that their citizens need to comply to, is weak.. There are exceptions, though. I think the EU has many measures in place and is serious about tackling emissions in climate majorly.
Global negotiations, in climate at least, are divisive so far, but the imperative to attend to them comes from an urgency to try for an agreement because all are affected.
So the era to correct past mistakes, as you put it, stems only because of self-interest..
