  abstract  = {In order to limit global warming and fulfill their contributions to the Paris agreement, both Germany and Japan have set targets for climate neutrality towards the middle of the century. Reaching these goals will imply transformation of all sectors of society to avoid all fossil greenhouse gas emissions, heavy industry not the least. The focus of this study is the transformation of the petrochemical industry. This sector can become climate neutral but cannot be {"}decarbonized{"}, as carbon is integral to the chemical structures of the products like polymers and solvents. Reaching climate neutrality thus means that the whole lifecycle of the petrochemical products has to be regarded. Another specific challenge is today's synergetic relation of this industry to fossil transport fuel production, which cannot be maintained in a climate neutral world. The two countries interestingly share a similar industrial structure overall, and the chemical and petrochemical industry is one of the major industries in both countries. The countries' respective chemical industries are the third and fourth largest in the world in terms of sales, but at the same time, these industries represent just over 5\% of the respective countries' greenhouse gas emissions. However, these scope 1 emissions of the chemical industry itself are far less relevant than the end-of-life emissions of their products, which belong to scope 3 and are thus not counted under the chemical industry in the country greenhouse gas balances. To mediate these emissions, there is a need to set the direction, draw out paths and investigate possible alternatives for how the petrochemical industry can be become climate neutral. In this report, the existing scenario analyses, energy strategies and roadmaps dealing with this issue in the two countries are compared, as well as the current state of their petrochemical industries. We highlight similarities, differences and identify possible areas of cooperation and exchange in order to find robust paths forward for the transformation of the petrochemical industries.},
