Bioconcentration tests with the freshwater amphipod Hyalella azteca (HYBIT) have been proposed as alternatives to fish tests, and the respective experimental BCF values show promising correlations. It is still unclear whether the HYBIT test is also suitable for highly hydrophobic chemicals, such as the UV stabilizers UV-234 and UV-329.

On 30 November 2022, the Commission proposed an EU carbon removal certification framework (CRCF). The proposed framework could undermine the environmental integrity of EU climate policies. This risk is aggravated by the fact that the EU has not agreed on the role of removals for the time past the year 2030.

The forest sector contributes to high emissions worldwide through the loss of historically built-up carbon stocks, mainly from deforestation and forest degradation. The REDD+ approach aims at compensating developing countries for efforts to reduce emissions from deforestation and forest degradation, to maintain and increase forest carbon stocks or to manage forests sustainably.

This paper presents possible urban Article 6 activities in Addis Ababa (Ethiopia) and Kampala (Uganda).

This report develops concrete structures for the use of urban carbon market approaches under Article 6 of the Paris Agreement for Addis Ababa (Ethiopia) and Kampala (Uganda). It takes into account both ongoing and planned emission reduction measures so that the results can be used effectively.

The subject of this project was the preparation of substance reports for five substances or substance groups relevant for building products emissions. For these substances, the toxicological data basis were researched, compiled and evaluated, and EU-LCI values were proposed. The EU-LCI values allow the harmonisation of the health assessment of building products emissions throughout Europe.

More than ten years after the recommendation of the updated CLRTAP critical levels for ammonia, new findings on the effects of ammonia on vegetation have been discussed in a workshop in Dessau Scientists dealing with research on effects of ammonia on vegetation and ecosystems and those involved in the monitoring of ammonia in the environment were asked to present their recent research.

To systematically bring nature back to cities, the EU Biodiversity Strategy calls upon cities with over 20,000 inhabitants to develop Urban Greening Plans (UGP). Nature based solutions (NbS) are at the centre of UGPs, addressing climate resilient infrastructures and biodiversity in cities together. They should agree with existing planning instruments.

Scrubbers, exhaust gas cleaning systems (EGCS) on seagoing vessels, are installed on about 25% of the world's merchant fleet and scrub sulphur from the exhaust gas. However, they discharge polluted discharge water into the marine environment. In the ImpEx project, discharge water samples were taken from ships and analysed in the laboratory for their harmful effects on the environment.

The Global Stocktake, a key component of the Paris Agreement’s ratchet mechanism, assesses global progress every five years with the goal of informing countries’ NDC updates.

Plant protection products, human and veterinary pharmaceuticals, biocides and other chemicals can reach surface waters during their life cycles, by direct or diffuse entry routes or because they are in completely removed during waste water treatment.

The discussion paper explores several options for the political phase of the first global stocktake (GST) under the Paris Agreement, which will be concluded at the end of 2023. This phase could be organised by thematic area as defined by the GST or structured by sector.
