New law is too weak and has been made harder to enforce, while transport ministry has not taken sufficient action, groups say

German climate activists are taking the government to court for “unconstitutional” climate policy, seeking to build on a landmark victory three years ago that they had hoped would force Europe’s biggest polluter to clean up quickly.

The activists argue that the new climate law is too weak, that a recent update makes it harder to enforce, and that inaction from the transport ministry, which has repeatedly failed to meet its emissions targets, will force tough measures on poor groups in the future.
