Nitrogen – Element with Impacts

An Integrated Target Value Sets a New Framework

Nitrogen emissions from almost all sectors of society lead to risks for humans and the environment. Sustainable management of nitrogen and its compounds therefore plays a major role in achieving the UN Sustainable Development Goals (SDGs). As a milestone towards sustainable nitrogen management, the German Environment Agency proposes a upper limit of 1,000 kt nitrogen per year for Germany. The limi...read more

Air Quality 2022

Preliminary Evaluation

This evaluation of air quality in Germany in the year 2022 is based on preliminary data which has not yet been conclusively audited from the air monitoring networks of the federal states and the UBA, valid on 31th January 2023. Due to the comprehensive quality assurance within the monitoring networks, the final data will only be available in mid-2023. The currently available data allows for a gene...read more

Methodological Convention 3.1 for the Assessment of Environmental Costs - Value Factors

Version 12/2020

The Methodological Convention 3.1 for the Assessment of Environmental Costs – Value Factors provides value factors for emissions of greenhouse gases, air pollutants, noise, nitrogen and phosphorus, as well as for transport, energy generation, building materials and greenhouse gas emissions in agriculture.The value factors show the benefit of environmental protection for society – and the costs tha...read more

Bioaccumulation assessment of superhydrophobic substances

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. In order to estimate the range in which the uptake rate consta...read more

Certification of Carbon Dioxide Removals

Evaluation of the Commission Proposal

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.This report assesses the Commission’s proposal for the CRCF and discusses interlinkages of t...read more

Potentials for “results-based payments” in the forest sector under the Paris Agreement

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 report examine...read more

Urban market approaches under Article 6 of the Paris Agreement

Recommendations for practical implementation

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. In addition to a status quo analysis of the emissions profiles of Addis Ababa and Kampala, the existing a...read more
