The Policy Brief discusses how a dedicated SPI should be established as a subsidiary body that works effectively with existing science-policy panels of other Multilateral Environmental Agreements. Such an interface would not only promote synergy between different environmental initiatives, but also ensure that scientific findings are accurately translated into actionable policy recommendations. The main tasks of the SPI include the evaluation and monitoring of intervention strategies, the setting of science-based reduction targets and the continuous updating of safety and sustainability-related criteria for plastics and chemicals.

Amidst intense global efforts to tackle plastic pollution, the Scientists' Coalition for an Effective Plastics Treaty highlights the critical role of reducing primary plastic polymers. The Scientists' Coalition, consisting of leading scientists worldwide, argues in its latest policy brief that without a significant reduction in the production of these polymers, the effective fight against plastic pollution is not possible. The urgent call aims to draw attention to the need to break the plastic cycle at its source - the production of primary plastic polymers. This approach is crucial as it directly reduces the amount of plastics that end up in our environment.

This briefing reviews the European Commission's first ever assessment of progress towards the 2050 climate neutrality target. Furthermore, it proposes steps that could be taken in the next two years to improve the system and provide a compass for the path to climate neutrality.

Securing agricultural land is a relevant challenge. The authors of the policy brief see a number of different approaches to safeguarding agricultural areas against other land use claims and are primarily addressing the state and municipal levels. The authors argue that the topics of agriculture, food, sustainability and rural development should be more closely integrated. They also recommend using spatial planning instruments to curb the current consumption of agricultural land and thus protect it from conversion.

As governments engage in final preparations for COP28 in Dubai, the United Arab Emirates (UAE) Presidency continues to prioritise its Food Systems and Agriculture Agenda. The aim to have governments at COP28 commit to integrating sustainable agriculture in their national climate agendas is welcome, timely and essential. But, it would need to be part of a larger effort to modernise agricultural policy, particularly with respect to agricultural subsidies and the role of private sector collaboration. This policy brief highlights priority areas in moving from political declarations to concrete action.

This document, drafted in 2023 and subsequently updated within the same year to reflect the latest advancements, delves into a policy milieu where the UN Decades of Ecosystem Restoration and the Water Decade emerge as pivotal, particularly bolstering SDGs 6 (Clean Water and Sanitation) and 14 (Life Below Water). The paper offers policy recommendations that advocate for the integration of specific measures into Nationally Determined Contributions (NDCs) and National Biodiversity Strategies and Action Plans (NBSAPs), alongside the proposal for a binding international water treaty and the appointment of a UN special representative for water.

This paper makes a proposal for how future EU agricultural policy and particularly funding structures should evolve to better reflect sustainability challenges whilst supporting farmers and other land managers in a transition that also ensures viable businesses and vibrant rural areas. This is intended as a contribution to a wider debate on the future of EU food systems.

As competition for, and interest in, use of ocean space increases, a need for management arises to optimize activity in marine areas. This policy brief provides a comprehensive consideration of the economic efficiency of marine multi-use (MU) by weighing the pros and cons of individual use options against potential MU combinations.

This edition of the policy brief represents the 2023 updated and content-revised version of the original document, thereby integrating the latest insights and developments in the field of Nature-based Solutions (NbS) and ecosystem restoration.

Since the signing of the Paris Agreement in 2015, global efforts towards achieving net zero emissions have been intensifying. However, progress has been sluggish, and current pledges and commitments fall far short of what is needed to limit global temperature rise to 1.5 °C by 2050. To achieve net zero emissions worldwide, a substantial deployment of renewable energy technologies and resilient supply chains is essential. This policy brief examines the critical role that the G20 can play in promoting cooperation and coordination to enhance the resilience of renewable energy supply chains.

This policy brief takes stock of the existing JETPs and draws some preliminary conclusions. More-over, it discusses some of the challenges JETP face and how JETPs may be improved. Lastly, we outline some recommendations for the G7 and G20.

This policy paper aims to inform discussions about the new policy monitoring mechanism by providing an overview of policy consistency and how to assess it. It discusses the specifics of consistency elaborated in the EU Climate Law, considers the academic and policy understanding of policy consistency and examines how this fits with the provisions in the law.

This policy brief aims to support the work of NGOs and think tanks by developing elements of a green hydrogen agenda for the G20. Based on an analysis of the heterogeneous interests and agenda of the G20 countries, the first part discusses the challenges and opportunities of the G20 as a forum for shaping the emerging markets for hydrogen and hydrogen-based products into a direction that is compatible with climate neutrality. The second section outlines the governance challenge of ensuring the environmental and social sustainability of hydrogen production and use. Finally, it develops options on how to advance a green hydrogen agenda in the G20.

This paper analyses the outcomes of the CBD COP15, specifically the adoption of the GBF and its implications for the UN Decade for Ecosystem Restoration. Delving into the GBF's long-term status goals for 2050 and 23 action goals for 2030, the paper highlights the importance of Action Target 2, which calls for initiating effective restoration processes in at least 30% of all degraded terrestrial, inland water, coastal, and marine ecosystems by 2030. It also explores how the UN Decade's global network, knowledge pool, and expertise can significantly contribute to the successful implementation of the GBF's restoration goals. The paper presents policy recommendations to ensure that the GBF's ambitious targets are met in a timely and effective manner.

The paper contains policy recommendations, including the integration of measures into NDCs (Nationally Determined Contributions) and NBSAPs (National Biodiversity Strategies and Action Plans), the consideration of a binding water treaty and a UN special representative for water. Synergies between freshwater ecosystems and flood protection should be highlighted, and cross-sectoral cooperation promoted.
