Policy incentives for the uptake of sustainable aviation fuels (SAFs)

Chain-of-custody approaches, administrative requirements and their impact

Aviation contributes approximately 2.5% of global CO2 emissions. When non-CO2 effects are taken into account, its overall climate impact is even higher. To mitigate these emissions, the use of sustainable aviation fuels (SAF) is crucial. SAF, produced from sustainable feedstocks, can significantly reduce life-cycle emissions compared to fossil kerosene. Despite policies promoting SAF uptake, their...read more

National Ordinance on Measures to Avoid Carbon Leakage in the National Fuel Emissions Trading System' (BEHG Carbon Leakage Ordinance, BECV)

Evaluation Progress Report

According to the approval under state aid law of the Carbon Leakage Ordinance of the Fuel Emission Trading Act (BECV) by the European Commission (State Aid SA.63191 (2023/N)), a comprehensive evaluation of the regulation is required by 2028. The aim of this evaluation is to examine the effectiveness of the BECV in terms of avoiding carbon leakage while maintaining competitiveness, promoting invest...read more

Urease- and nitrification inhibitors for climate and environmental protection: opportunity or risk?

Urease and nitrification inhibitors are used in agriculture to reduce ammonia and nitrous oxide emissions and the leaching of nitrate. However, the risks of inhibitors for human health and the environment have not yet been sufficiently investigated. Also, the specific effectiveness of different urease and nitrification inhibitors has not yet been sufficiently clarified. These uncertainties have so...read more

Particulate Matter emission reduction in international maritime shipping

Analysis and discussion of current status and outlook

In addition to the air pollutants nitrogen oxide (NOX) and sulphur oxide (SOX), seagoing vessels emit considerable quantities of particulate matter (PM). These emissions are not yet regulated either internationally or regionally.The report provides an overview of PM measurement methods and limit values in other transport sectors. It also describes ship-specific measures to reduce PM emissions, inc...read more

Nature-based Solutions and their Governance Structures for Climate Action in the Alpine Region

The German Environment Agency initiated a project to promote nature-based solutions (NbS) in the Alpine region. The aim is to highlight the importance of NbS for biodiversity, climate protection and adaptation, and to analyze political and cross-sectoral governance mechanisms for the Alpine Convention (AC) region. Eight pilot projects from seven AC countries were examined to identify success facto...read more

Terrestrial biological monitoring on Fildes Peninsula (Maxwell Bay, Antarctic)

The analysis of decades of data series on the occurrence of penguins and seabirds in Maxwell Bay contributes to the understanding of the effects of climate change on the marine ecosystems in the area of the northern Antarctic Peninsula. The species spectrum of penguins is shifting further in unfavour of the "true" Antarctic species, while sub-Antarctic penguins continue to increase in population....read more
