This paper presents a technical assessment of nature-related risks within the Hungarian economy and financial system. The study draws upon the OECD Supervisory Framework to (i) prioritise various nature-related risks by conducting an impact and dependency assessment, identifying key economic sectors, and pinpointing the critical natural capital assets that are most crucial to the financial system; (ii) assess the direct and indirect economic impact of three exploratory scenarios on possible acute nature-related shocks using input-output analysis; (iii) explore the different financial risk channels through which economic risks stemming from nature-related losses may be transmitted within the Hungarian financial system; and (iv) provide supervisory recommendations based on the results.

This working paper takes stock of the literature on behaviourally-informed interventions to facilitate the transition to a circular economy and discusses measures that could be pilot tested in Italy. It provides an overview of the key concepts of behavioural economics and describes the main 'biases' that could influence the adoption of behaviours aligned with the transition to a circular economy by consumers. It goes on to review the empirical evidence on the motivations that may affect the adoption of such behaviours, as well as the empirical insights into the effectiveness of implemented behavioural interventions relevant to the circular economy transition. Finally, the paper introduces three proposals for experimental pilots in Italy.

This new web format for Environment at a Glance Indicators provides real-time interactive on-line access to the latest comparable OECD-country data on the environment from the OECD Core Set of Environmental Indicators – a tool to evaluate environmental performance in countries and to track the course towards sustainable development. The web version allows users to play with the data and graphics, download and share them, and consult and download thematic web-books. These indicators provide key messages on major environmental trends in areas such as climate change, biodiversity, water resources, air quality, circular economy and ocean resources. They are accompanied by a short Environment at a Glance report that presents a digest of the key messages stemming from the indicators.

This paper takes stock of international good practices to measure progress and impacts towards a circular economy, based on existing circular economy strategies and related measurement frameworks at different levels of government. It also provides an overview of 215 operational and aspirational indicators available in Italy from official statistical sources and targeted circular economy reports. It highlights measurement challenges and concludes by identifying opportunities to expand the monitoring framework in Italy to measure progress towards a circular economy.

To better address the impacts from climate change, OECD countries are increasingly making climate change adaptation a policy priority. Assessing progress in the implementation of national adaptation policies is a critical step in understanding how adaptation efforts contribute to strengthening climate resilience, and whether they are effective. Experience in policy design and implementation has grown significantly, however measuring progress remains a challenge for countries. Building on a cross-country survey and country case studies carried out in Chile, Korea, the Slovak Republic and the United Kingdom, this report provides insights into current OECD country practices in measuring climate adaptation. It proposes a framework that can guide countries on what needs to be measured and how, and discusses the role that adaptation indicators and a conducive institutional environment can play in strengthening adaptation measurement.

Policies that foster the transition towards a more circular economy are gaining significant traction. Such policies are essential for a sustainable, low-carbon, resource-efficient and competitive economy. These developments bring about demands for reliable information to track progress and gauge results as well as for indicators that speak to policymakers and the public at large. This report presents a conceptual framework and indicator set to monitor progress and inform circular economy policies. It is designed to support OECD work on circular economy and provides a source of inspiration for countries seeking to build a coherent circular economy monitoring framework.

The Hyalella azteca Bioconcentration Test (HYBIT) provides a non-vertebrate test for bioconcentration in aquatic environments. The test consists of two phases: the exposure (uptake) and post-exposure (depuration) phases. During the uptake phase, a group of H. azteca is exposed to the test chemical at one or more chosen concentrations. They are then transferred to a medium free of the test chemical for the depuration phase. The concentration of the test chemical in the analysed H. azteca is followed through both phases of the test. Parameters which characterise the bioaccumulation potential include the uptake rate constant (k1), the depuration rate constant (k2), the steady-state bioconcentration factor (BCFSS) and the kinetic bioconcentration factor (BCFK).

This Test Guideline (TG) describes a short-term juvenile hormone (JH) activity screening assay using Daphnia magna to detect the potential of chemicals with JH activity. The JHASA was designed as a screen assay which evaluates male offspring production in the parthenogenetic daphnid.

This Test Guideline describes a Rapid Estrogen ACTivity In Vivo (REACTIV) Assay in an aquatic assay that utilises transgenic Oryzias latipes (Japanese medaka) eleutheroembryos at day post hatch zero, in a multi-well plate format to identify chemicals active on the estrogen axis. The REACTIV assay was designed as a screening assay to provide a medium throughput and short-term assay to measure the response of eleutheroembryos to chemicals potentially active on the estrogen axis.

The Local Lymph Node Assay: BrdU-ELISA (LLNA:BrdU-ELISA) is a non-radioactive modification to the LLNA method for identifying potential skin sensitizing test substances and measuring the proliferation of lymphocytes they induce in the auricular lymph nodes. The method described in mouse  is based on the use of measuring 5-bromo-2-deoxyuridine (BrdU) content, an analogue of thymidine, as an indicator of this proliferation. A minimum of four animals is used per dose group, with a minimum of three concentrations of the test substance, plus a concurrent negative control group and a positive control group. The experimental schedule is during 6 days. Thereafter, the animals are killed and a single cell suspension of lymph node cells (LNC) is prepared. The procedure for preparing the LNC is crucial, in particular for the small lymph nodes in NC animals. Then the BrdU content in DNA of lymphocytes is measured by ELISA using a commercial kit of by Flow Cytometry (FCM). This study includes: measurements (weighing, BrdU) and clinical daily observations. The results are expressed as the Stimulation Index (SI) obtained by calculation from the mean BrdU labelling index. The SI should be ≥1.6 for the ELISA method or ≥2.7 for the FCM method for identifying the test material as a potential skin sensitizer.
