What can justice look like on the bottom of the ocean?

With the rapid growth of the technology sector over the past decade, the demand for metals such as copper, manganese, cobalt and other rare earth minerals has increased many times over. The deep seabed as a potential source of these minerals seems particularly attractive against this backdrop, especially as industrial deep seabed mining is now close to operationalization.

Hydrogen: A Future Cornerstone of EU-Russia Energy Relations?

Green hydrogen is set to play a central role in the efforts of the European Union and many EU member states to decarbonize different sectors in order to reach their 2050 climate goals. The hydrogen strategy adopted by the European Commission in July 2020 seeks to make green hydrogen an integral part of Europe’s energy system by 2050. In particular, the strategy emphasizes the potential of green hydrogen in sectors where direct electrification is a challenge, including energy storage, heavy-duty transport, aviation, shipping, and energy-intensive manufacturing. However, in order to enable a market ramp-up for hydrogen, low-carbon hydrogen derived from fossil fuels is also being considered as a production option alongside green hydrogen.

Less Panic, More Dynamic – Why Climate Protection Needs to be Framed Differently

Do you remember the 2019 World Economic Forum in Davos? “I want you to panic. I want you to feel the fear I feel every day. And then I want you to act” – that was Greta Thunberg’s impassioned plea to the participants, and the rest of the world. Now, almost two years after her remarkable speech, the international community is celebrating the fifth birthday of the Paris Climate Agreement. On this anniversary, the focus has been firmly on the updates by individual state parties to their Nationally Determined Contributions (NDCs). But there’s little to celebrate: only 21 of 197 states have submitted new or updated plans, excluding most of the major emitters. And concrete climate protection measures are few and far between.

The Paris Agreement turns five: It’s high time we tackle the ocean and climate crises together

Five years have passed since the so-called ‘Paris Agreement’ was concluded at the 21st Conference of the Parties (COP) to the UN Framework Convention on Climate Change (UNFCCC) following years of deliberation between the member States. For the ocean, the Paris Agreement represents a turning point: previously issues relating to the ocean were side-lined in COP negotiations.

The Impact of Narrative Messaging on Behavioral Change towards Sustainable Diets: Results of US Survey

Food consumption and production are one of the key entry points available to human societies for effecting a transformation towards sustainability. Food production is a major contributor to a whole range of environmental problems including climate change, biodiversity loss, water overuse, and air and water pollution. Also, unhealthful diets cause chronic disease and millions of premature deaths around the world each year. One common link between these two unsustainable trends is high levels of consumption of animal products—meat, dairy, eggs, etc., particularly in industrialized countries, but also increasingly in developing countries. Thus, efforts to shift diets en masse away from animal products towards plant-based foods can reap multiple sustainability benefits.

Can the climate change agenda ‘save’ the Amazon?

Concern with the Amazon is common in international climate discourse. Indeed, “saving” the Amazon for the sake of the climate has become a rallying cry among climate policymakers and researchers alike. In this post, I want to argue that while curbing deforestation in the Amazon is undoubtedly important, framing the challenge as a mission to “save” the Amazon in order to fight climate change is problematic.

A Green New Deal for the Amazon: Reconciling Conservation and Development

Brazilian geographer Bertha Becker referred to the Amazon region as the oldest periphery of the capitalist world system. Its colonial occupation, or 'frontier economy', is based on the continuous incorporation of available land and the exploitation of their resources – both of which are regarded as infinite. This perspective on the Amazon has existed for centuries and continues to loom large in Brazil today. To meet its growing demand for raw materials, the outside world assumed the rainforest to be of little value, discounting the services that it provides to humankind. This view encourages the rainforest’s destruction and is not sustainable. A model for the sustainable development of the Amazon region is feasible however and could play an important role in Brazil's post-pandemic economic recovery efforts.

Financing the Green Transition through Off-Balance-Sheet Fiscal Agencies

In recent years, there have been increasing calls for central banks to become pioneers in sustainability transformation. Is this the best idea - or are there alternatives? In the blog post written by Andrei Guter-Sandu and Steffen Murau, the authors present an alternative and reflect on the implications of their proposal for a "green transition" towards a more sustainable economy. It refers to an essay published in the "Wirtschaftswoche" on the democratization of the Eurozone.

“Socialising” energy models: It’s time to put social concerns in energy models

On the 7th of October, the European Parliament voted to adopt a more ambitious climate target to reduce EU emissions by 60% in 2030 compared to 1990, up from 40% currently. Policymaking and planning decisions towards this target are not straight forward, and it bears the question: How can we foster the societal and political acceptance needed to completely decarbonise our energy systems? While energy models can be used to study the pathways towards a decarbonised energy system, they largely neglect the social and political dimensions of the energy transition. To provide more realistic, relevant, and sustainable decision-advice, it’s time for energy modellers to integrate social concerns in their models.

Modellers meet decision-makers: User needs for energy models for the European energy transition

The energy transition raises many questions about how to achieve and design net-zero emission energy systems. Energy models can support decision-makers by providing virtual laboratories in which different energy futures can be explored. But what are the requirements of different stakeholders on these energy models? Which challenges of the energy transition should they tackle? What questions should these models be able to answer? In order to identify needs and discuss the expectations placed on energy modelling in the framework of the project Sustainable Energy Transition Laboratory (SENTINEL), we conducted an online survey in summer and held an online expert workshop on the 1st of October.
