Germany has continued to improve its environmental performance over the past decade. It has ambitious climate targets with the aim to reach climate neutrality by 2045 and achieve negative emissions after 2050. Nevertheless, Germany will need to further accelerate climate action, particularly in the buildings and transport sectors, and address the triple crisis of energy, climate and biodiversity in an integrated and holistic manner. As part of its energy crisis response, Germany has taken a series of measures, which are historic in size and scope. They are set to massively accelerate its green energy transition in the coming years. It is also scaling up its engagement on climate change adaptation across all government levels and has initiated an ambitious programme to foster investments in nature-based solutions. This is the fourth OECD Environmental Performance Review of Germany. It provides 28 recommendations to help Germany further improve its environmental performance.
