Im Jahr 2021 fielen in Deutschland 5,44 Millionen Tonnen Post-Consumer Kunststoffabfälle an, von denen lediglich 33% recycelt wurden. Über die Hälfte dieser Abfälle wird derzeit verbrannt, was bedeutet, dass wertvolle Ressourcen ungenutzt bleiben. Die geringe Verwendung von Kunststoffrezyklaten in der Produktions- und Verarbeitungsindustrie deutet auf mangelnde (finanzielle) Anreize hin. Um das Kunststoffrecycling bzw. den Rezyklateinsatz zu fördern, werden verschiedene Maßnahmen vorgeschlagen. Dazu zählen produktspezifische Rezyklateinsatzquoten, polymerspezifische Substitutionsquoten und Zertifikatlösungen. Des Weiteren könnten Abgaben auf nicht hochgradig recyclingfähige Verpackungen sowie eine Verbrauchssteuer für Verpackungen den Einsatz unnötiger Verpackungen verteuern und den Einsatz von Rezyklaten fördern. Auch die Rolle des chemischen Recyclings wird in diesem Kontext näher erläutert und differenzierter in die Abfallhierarchie eingeordnet.

The Paris Agreement establishes provisions for using international carbon market mechanisms to achieve climate mitigation contributions. Environmental integrity is a key principle for using such mechanisms under the Agreement. This paper systematically identifies and categorizes issues and options to achieve environmental integrity, including how it could be defined, what influences it, and what approaches could mitigate environmental integrity risks. Here, environmental integrity is assumed to be ensured if the engagement in international transfers of carbon market units leads to the same or lower aggregated global emissions. Four factors are identified that influence environmental integrity: the accounting for international transfers; the quality of units generated, i.e. whether the mechanism ensures that the issuance or transfer of units leads to emission reductions in the transferring country; the ambition and scope of the mitigation target of the transferring country; and incentives or disincentives for future mitigation action, such as possible disincentives for transferring countries to define future mitigation targets less ambitiously or more narrowly in order to sell more units. It is recommended that policy-makers combine several approaches to address the significant risks to environmental integrity.

Die dringende Transformation unseres Energiesystems hin zu einer nachhaltigen Infrastruktur der Daseinsvorsorge scheitert in der regionalen Umsetzung regelmäßig an raumbezogenen und gesellschaftlichen Anforderungen des ländlichen Raums. In diesem Beitrag werden amBeispiel eines transdisziplinären Projektes Dilemmata in der partizipativen Umsetzung der regionalen Energiewende identifiziert und Gelingensbedingungen einer raumsensiblen Energiewende-Governance formuliert. Wie mit dem entwickelten Governance-Ansatz zur „Co-Transformation“ gezeigt wird, können kontextsensitive Partizipationsformen der Co-Regulierung, Co-Allokation und Co-Visionierung zur Verfahrens-, Verteilungs- sowie Zukunftsgerechtigkeit und damit zur Akzeptabilität der regionalen Energiewende als Daseinsvorsorgeinfrastruktur im ländlichen Raum beitragen. Zentrale Maßnahmenfelder sind dabei ergebnisoffene und regional angepasste Formen der Mitwirkung durch die Co-Regulierung im Planungsprozess, Ansätze zur räumlichen Co-Allokation energiewendeb

Research into sufficiency at business level often focuses on pioneers and a bottom-up approach to transformation. However, business activities are shaped and limited by political framework conditions. We analyze the interdependent relationships between business and policy making, arguing for greater emphasis on the structural perspective to foster sufficiency-oriented shifts in business.

An increasing number of countries employ net-zero decarbonization targets in their climate policies, which requires decarbonizing socio-technical systems like the energy system by mid-century. While there is a high level of agreement about net-zero targets, there remains great uncertainty as to how to meet them. At the same time, the challenges of building a new system that fulfils systemic targets such as net-zero are insufficiently reflected on in the sustainability transitions literature. With the help of a literature review building on theories of socio-technical transitions, this paper introduces system building dimensions that account for the difficulties of net-zero transitions. We identify four such dimensions: (1) competing potential system configurations with different sustainability implications; (2) a broad range of complementary system elements needed; (3) lock-ins and path dependencies in the system building process; and (4) the politics of system building. We offer the German energy transition

The transport sector is not on track to meet the Paris Agreement climate targets. Rapid decarbonization of transport requires fuel switching and energy savings through modal shift and demand reduction – which are the aims of transport-sufficiency policy. We analyze passenger transport-policy instruments collected in the European Sufficiency Policy Database. Applying the concept of impact chains, we examine the ways in which proposed policy instruments function from cause/policy stimulus to effect/impact, with a focus on the factors relevant to the feasibility of policy implementation in Germany. This allows us to compare implementation feasibility by policy target and by instrument type. Based on our analysis of supporting factors, barriers, and risks, we find that policy instruments with many supporting factors also tend to have many barriers and risks. This is often the case with broad instruments that have diverse relevant factors. We observe that the policy targets “promotion of active modes” and “reducti

Hoping to support sustainability, countries have established policies to foster the bioeconomy (BE), based on the use of biomass and knowledge on biological principles. However, appropriate monitoring is still lacking. We estimate global key environmental footprints (FPs) of the German BE in a historic analysis from 2000–2015 and in projection until 2030. Overall, the agricultural biomass FP is dominated by animal-based food consumption, which is slightly decreasing. The forestry biomass FP of consumption could potentially shift from net import to total supply from domestic territory. Agricultural land use for consumption is triple that of domestic agricultural land (which covers half of Germany) and induced substantial land use change in other regions from 2000–2015. The FP of irrigation water withdrawals has decreased over 2000–2015 and might continue to decline in absolute terms by 2030, but the share of supply regions with water stress might increase. The climate FP of BE contributes 18–20% to the total climate FP of domestic consumption, while employment makes up 10% and value added only 8% of the total German economy. These findings imply that sufficient monitoring of the BE needs to consider both production and consumption perspectives, as well as global FPs of national economies.

The EU’s regulatory framework for genetically modified organisms (GMOs) was developed for “classical” transgenic GMOs, yet advancements in so-called “new genomic techniques (NGTs)” have led to implementation challenges regarding detection and identification. As traceability can complement detection and identification strategies, improvements to the existing traceability strategy for GMOs are investigated in this study. Our results are based on a comprehensive analysis of existing traceability systems for globally traded agricultural products, with a focus on soy. Alternative traceability strategies in other sectors were also analysed. One focus was on traceability strategies for products with characteristics for which there are no analytical verification methods. Examples include imports of “conflict minerals” into the EU. The so-called EU Conflict Minerals Regulation requires importers of certain raw materials to carry out due diligence in the supply chain. Due diligence regulations, such as the EU’s Conflic

Meeting energy and climate targets requires phasing out the use of fossil fuels in the heating sector, demanding an extensive overhaul of infrastructure. The expansion of district heating and electricity distribution grids will be essential for this transition, while parts of the gas distribution network will become redundant. Regional and municipal heating plans, mandated by the EED and the decarbonised gas and hydrogen market package, require planning that should involve identifying areas where gas distribution networks will be decommissioned or dismantled in the future. The process will be accelerated by phasing out or introducing efficiency regulations for heating installations. How should the efficient and orderly transformation of the gas network be accomplished? To this end, we compare the status-quo as well as recent the developments of gas grid infrastructures across four European countries, namely Austria, Germany, the Netherlands, and the UK. Additionally, we analyse the current regulations for ga
