Stopping Biodiversity Loss, Human Rights, and International Environmental Law

The CBD as well as (national and transnational) human rights contain an obligation to halt biodiversity loss since 1993 at the latest, which has been continuously violated ever since. Governments can also be sued on this basis. We show this in a new international paper: here.

Negative Emissions: Forests, Peatlands - and Geoengineering?

Even with zero fossil fuels and greatly reduced animal husbandry, residual emissions remain that must be compensated - even if sufficiency can make this amount of emissions smaller than the IPCC assumes. This requires above all the regulation of forests and peatlands (which are also central to biodiversity protection). Here, economic instruments and regulatory law relate to each other differently than they often do. Three international articles explore this - on forests, on peatlands and on the very problematic large-scale BECCSand other kinds of geoengineering.

Paris Target, Human Rights, and our Groundbreaking Constitutional Court Verdict on Unambitious Climate Protection and Precautionary Principle

German and EU climate policy is contrary to international law and constitutional human rights. Even the unambitious targets themselves are illegal. More on this in our new legal analysis, including critical perspectives on IPCC AR6 here. In April 2021, we won a groundbreaking lawsuit at the German Constitutional Court. See on this in Nature Climate Change, in The Environment and Sustainability.

Economic Instruments for Phosphorus Governance - Climate and Biodiv Targets

The existing legal framework on P is strongly characterized by detailed command-and-control provisions and thus suffers from governance problems such as enforcement deficits, rebound and shifting effects. Our new paper focuses on how these challenges could be addressed by economic instruments. The article highlights not only the impact of the instruments on P management, but also on adjacent environmental areas. We pay particular attention to the governance effects on reaching international binding climate and biodiv goals: here.

Land Use, Livestock, Quantity Governance, and Economic Instruments

The production of animal food products is (besides fossil fuels) one of the most important noxae with regard to many of the environmental problems, such as climate change, biodiversity loss or globally disrupted nutrient cycles. This paper provides a qualitative governance analysis of which regulatory options there are to align livestock farming with the legally binding environmental objectives, in particular the Paris Agreement and the Convention on Biological Diversity: here.

Jutta Wieding, M.A. is a member of the Research Unit Sustainability and Climate Policy since 2013. Since 2017, she is working on her PhD thesis on the subject of regulation of greenhouse gas emissions from land use resulting from animal products – status and perspectives for transnational governance instruments (in cooperation with University of Rostock, Faculty of Agricultural and Environmental Sciences, Soil Science), funded by Heinrich Böll Foundation. She holds a Master of Arts in International Relations from Technical University of Dresden. In the context of her contributions to InnoSoilPhos (Innovative Solutions to Sustainable Soil Phosphorus Management), she worked on questions of international climate policy as well as governance of soil protection and sustainable agriculture, focusing especially on economic governance instruments and integrated solutions for connected ecological problems. Jutta Wieding is member of the board of Friends of the Earth Saxony and president of Friends of the Earth Dresden. Also, she is active in the scientific body of Friends of the Earth Germany in the working groups Environmental Ethics (Co-Chair) and International Environmental Policy. With her qualification as „Zukunftspilot“, she works as freelancer as facilitator for environmental issues and in NGO development.
