The main task was to advise the BMZ on the analysis, conceptualisation, and further development of its downstream emissions. For that a benchmark study to assess, examine, and manage downstream emissions GHG emissions from its project portfolio was created. The study aimed to investigate existing approaches worldwide, highlighting experiences, opportunities, and limitations. The purpose was for the BMZ to learn from international actors, particularly from the development cooperation field. A discussion paper was intended to critically assess the BMZ’s approaches, identify challenges, and present solutions that are relevant to international actors as well. Additionally, the study aimed to capture and consider the environmental and climate-related impacts of German and international development cooperation within national partner systems. Concrete country examples with assessments from national stakeholders were developed.
