Preparation of a short study for the extension or recalculation of the existing climate protection sector targets of Hesse for 2030


The state of Hesse aims to become climate neutral by 2045 at the latest. To achieve this, the new Hessian Law for the Promotion of Climate Protection and Adaptation to the Consequences of Climate Change (Hessisches Klimagesetz – HKlimaG) defined a new and increased climate target for 2030. The central basis for the further development of the Integrated Climate Protection Plan (IKSP) is the target of 65% greenhouse gas reductions in the state by 2030 compared to the base year 1990. This reduction target is composed of reduction targets of all greenhouse gas relevant sectors (energy generation, households, trade and services, industry, transport, agriculture, waste and wastewater management).


Arepo was already commissioned by the state of Hesse in 2020 to determine possible sector targets within the scope of a study. In this project Arepo updates the data for the calculation of the sector targets in 2030 for the new climate target of 65% compared to 1990, due to the changed framework conditions in Hesse and on EU and federal level since the calculation of the original sector targets. The results of this study will be used by the Hessian state government to legislate and adapt the state’s sector targets to the new regulations.

The study is prepared by Arepo in cooperation with the Lankwitz Institute for Technology and Environment (LITE). In order to determine the sub-targets, the existing climate policy requirements on EU, federal and state level are first examined as well as the structural characteristics of the respective sector in Hesse. Then, plausible reduction targets are modeled for each sector for the year 2030 and it is shown how these targets can be achieved.
