Berlin (AFP) Numerous environmental and relief organizations call for specific proposals of the Federal Government in the fight against global warming at the UN climate summit in New York. The meeting at the highest political level must yield more "than a mere confirmation of the relevance of the sustainability and climate targets and a naming of voluntary measures," it said in a joint communication of the Forum Environment & Development, the Climate Alliance Germany and the Association Development Policy and Humanitarian aid (Venro) from Monday.
