Simple: Germany has a huge export surplus that China and the USA is unwilling to accept anymore. Also, German economy is stagnate, based on a cheap russian gas and cooperation with china. So now, the idea is to target South America for exports while balancing it with import of South American foodstuff(EU-Mercosur agreement, that we know will not be ratified by individual countries in a democratic process, but by the Commission). The problem Germany has to fix is the Common Agricultural Policy, that's one of the pillars of the EU. So, they are using the Green Agenda to force countries to reforest their fields. Of course the whole reforestation program is designed in a way that benefits states (Germany) that have got rid of their forests long time ago, and is unfavorable for countries that developed their agriculture after the WW2 - like Denmark and Finland. So expect a heated discussion between Germany and France, rise of right wing parties in smaller countries, and a push for stricter integration.
