The global community is far from achieving its objective of ending plastic pollution, unless more stringent and co-ordinated policies are implemented. A key question is: What are the plausible scenarios for the evolution of plastics in the absence of additional measures and, as well, with scaled-up policy action? The Global Plastics Outlook: Policy Scenarios to 2060 provides such a forward-looking perspective. The report presents a set of coherent projections on plastics to 2060, including plastics use, waste as well as the environmental impacts linked to plastics, especially leakage to the environment. Such an outlook on plastics can help policy makers understand the scale of the challenge to transition to a more sustainable and circular use of plastics and the need for additional policy action. By identifying two policy packages to bend the plastic curve, the Outlook allows for a better understanding of the environmental benefits and economic consequences of adopting stringent policies. This second report is a follow-up to the first report – Global Plastics Outlook: Economic Drivers, Environmental Impacts and Policy Options – which quantified current trends in plastics use, waste generation and leakage, as well as identified four policy levers to curb the environmental impacts of plastics.

Reducing air pollution is a major policy challenge, especially in densely populated urban areas where human exposure to emissions is considerable. This paper develops and examines a series of scenarios for the evolution of transport-related emissions in the area of Santiago, Chile. The analysis suggests that ramping up efforts to electrify the bus fleet may eliminate 25% of the CO2 and at least 10% of the remaining air pollutant emissions in 2050. These figures increase to 45% and 30%, respectively, if rapid electrification is accompanied by tax schemes. The paper highlights the potential synergies of policies curbing climate change and tacking air pollution from the viewpoint of urban transport.

Combatting climate change is among the most critical issues on the global policy agenda. The transition towards a greener economy will require a pivot towards more sustainable production processes and consumption patterns. Entrepreneurs have the potential to be a major driving force behind this effort through their capacity to develop and propagate innovative green solutions. To unlock this potential, it is crucial for policy makers to implement appropriate policies and measures that enable green entrepreneurs to thrive. This report identifies lessons from international policy practices in stimulating and supporting green entrepreneurship from three case study countries – Canada, Germany and Israel – to inform Denmark about effective policy practices and pitfalls to avoid as it implements initiatives to strengthen its green transition. Recommendations are offered across a number of areas such as promoting greater co-ordination between relevant policy actors, strengthening specialised support for green entrepreneurs and building green markets.

This paper explores modalities, enablers, and political moments that could help to translate the outputs of the global stocktake (GST) into an outcome that informs and enhances national and international actions as intended in the Paris Agreement. How to move from the collective outputs of the GST to desired outcomes is critical but not straightforward. Drawing on lessons learnt from previous international assessment and review processes under the UNFCCC and beyond, this paper sets out insights on modalities, outputs and enabling factors that could help ensure the GST leads to action on the ground. The paper concludes that achieving the outcomes of the GST requires a well-designed process that effectively engages Parties and non-Party stakeholders in separate but sequenced technical and political discussion tracks. The paper also finds that specific, actionable outputs that target different actors can facilitate subsequent follow-up. The paper identifies different enabling factors that could support the translation of GST outputs formulated at the collective level into national processes to update and enhance actions and support. It also highlights the importance of leveraging different political moments and building linkages with parallel processes, both within and outside the UNFCCC context, to maintain momentum on the GST and ensure operational action follows over time so that collective efforts are in line with the long-term goals of the Paris Agreement.

Greenhouse gas (GHG) mitigation actions will need to be accelerated and scaled up at both national and sub-national levels in order to meet the temperature goals of the Paris Agreement. National governments can play an important role in enabling GHG mitigation actions by non-Party stakeholders (NPS), and in enhancing the interaction between national policies and NPS actions. This paper explores actions national governments could take to facilitate NPS mitigation action in two sub-sectors with large mitigation potential and where NPS play a key role in the successful implementation of mitigation activities. These sectors are renewable electricity generation and procurement in cities and Reducing Emissions from Deforestation and forest Degradation in sub-national jurisdictions. This paper outlines some institutional, regulatory, financial and technical barriers faced by NPS in implementing GHG mitigation activities in these sub-sectors and highlights some examples of national policies and measures that have allowed specific NPS to overcome these barriers. The paper also showcases examples of enabling policy frameworks at the national level that could encourage the replication of such mitigation actions by NPS. An important, common element for successful replication of mitigation activities is for national governments to facilitate co-ordination with NPS; to improve consistency between national and sub-national policies; to identify and clarify responsibilities between different actors; and to regularly review and potentially revise national policies that may unintentionally create barriers to NPS mitigation actions.

To contribute to the existing pool of evidence on the dynamic interplay between illicit trade and armed conflicts, this report looks at illicit trade flows in four separate conflict-affected countries in the MENA region: Iraq, Libya, Syria and Yemen. For the case of Yemen, the report also presents a deep-dive analysis of illicit trade flows and the relevant governance environment. The findings highlight that illicit trade networks in these countries are dynamic, complex, and heavily integrated into regional and global networks.

Pharmaceutical household waste from expired or unused medicine does not only offer zero therapeutic benefit, but also contributes to environmental pollution when disposed of via improper routes. Medicines discarded in sinks and flushed down toilets enter sewage waters and, if not filtered out, leak into aquatic systems. Disposal of unused or expired medicines via solid household waste can also result in pharmaceutical residues entering the environment if this waste is illegally dumped, or destined for landfills. In addition to environmental risks, unused or expired medicine not only constitutes wasted healthcare resources, but also presents a possible public health risk of accidental or intentional misuse and poisoning if extracted from waste bins. Preventing pharmaceutical household waste and ensuring the effective collection and environmentally sound treatment of unavoidable waste is thus an important policy objective. This report provides an overview of available data on pharmaceutical consumption and disposal practices across OECD countries, reviews existing collection schemes and provides recommendations to best prevent, collect and treat unused or expired medicines in order to avoid their leakage into the environment.
