Nationally defined contribution is a nice way of saying global carbon tax [1]. I mean sure the UN doesn't have a way to enforce the tax, but it's still a tax. Presumably this tax would wind up somewhere and someone, not the person who contributed it would spend it. This money spent would go to someone based on somebody's decision. Perhaps this company would be the recipient? There is so much pussyfooting around the whole issue of what the paris agreement was about due to politics. It's freaking underwear gnomes from South Park levels of hiding what's actually going on.
