The damage functions in the models, which relate GDP to temperature and sea-level rise, account for impacts on agriculture, forestry, fisheries, floods, road infrastructure, energy supply and demand, and labor productivity. Using this novel approach, the researchers estimate that the avoided damages are 1.5-3.9 times higher than the costs of climate mitigation. In other words, one euro invested in climate solutions saves the world about 1.5 to 4 euros in effects from climate change.

Human activity is putting the Earth on a trajectory towards environmental collapse. The SDGs were adopted in2015 to reconcile human activity with planetary boundaries. So far, the SDGs have not lived up to their promise in European Union member states. Most EU countries have seen socioeconomic development alongside environmental degradation. Progress towards environmental sustainability only occurs in countries with slow or negative socioeconomic trends.

The IPBES #PandemicsReport is one of the most scientifically robust examinations of the evidence and knowledge about links between pandemic risk and nature since the COVID-19 pandemic began - with 22 of the world's leading experts from fields as diverse as epidemiology, zoology, public health, disease ecology, comparative pathology, veterinary medicine, pharmacology, wildlife health, mathematical modelling, economics, law, and public policy as authors of the report. The expertise of the 22 authors was further augmented by contributions and knowledge resources from the Convention on Biological Diversity, the Intergovernmental Panel on Climate Change, the Convention on International Trade in Endangered Species, the United Nations Convention to Combat Desertification, and the World Health Organization - as well as a peer review process.

We must do what we can to contain Vladimir Putin’s aggression in Ukraine. But we also need to be clear-eyed about it, and face the costs. Economics can’t be separated from politics, and neither can be separated from history. Here are eight sobering realities:

L’Institut de l’économie pour le climat ( I4CE – Institute for climate economics) est une association experte de l’économie et de la finance dont la mission est de faire avancer l’action contre les changements climatiques.

Et si l’Europe en attendait trop de ses forêts ? Selon un récent rapport du cabinet de conseil Material Economics, en pointe sur les sujets liés à la durabilité et l’économie, l’Union européenne "surestime de loin l’offre de biomasse d’origine végétale et forestière potentiellement disponible".

Comment les économistes abordent le changement climatique et quelles sont les solutions prônées pour y faire face ? Est-ce que leur approche joue un rôle dans notre incapacité à limiter les émissions de gaz à effet de serre ?

How is it possible to own land? The current pattern of ownership and control of land lies at the heart of many of our biggest dysfunctions: the collapse of wildlife and ecosystems, the exclusion and marginalization of so many people, the lack of housing in many cities—indeed, in many parts of the world—the lack of public space in cities, our exclusion from the countryside. The pattern of land ownership underlies all of these massive issues, and indeed of many more. Yet we rarely question it.

Human activities are threatening to push the Earth system beyond its planetary boundaries, risking catastrophic and irreversible global environmental change. Action is urgently needed, yet well-intentioned policies designed to reduce pressure on a single boundary can lead, through economic linkages, to aggravation of other pressures. In particular, the potential policy spillovers from an increase in the global carbon price onto other critical Earth system processes has received little attention to date. To this end, we explore the global environmental effects of pricing carbon, beyond its effect on carbon emissions. We find that the case for carbon pricing globally becomes even stronger in a multi-boundary world, since it can ameliorate many other planetary pressures. It does however exacerbate certain planetary pressures, largely by stimulating additional biofuel production. When carbon pricing is allied with a biofuel policy, however, it can alleviate all planetary pressures. In the light of nine Earth Syst

While climate scientists warn that climate change could be catastrophic, economists such as 2018 Nobel prize winner William Nordhaus assert that it will be nowhere near as damaging. In a 2018 paper published after he was awarded the prize, Nordhaus claimed that 3°C of warming would reduce global GDP by just 2.1%, compared to what it would be in the total absence of climate change.

CCS - Carbon Capture and Storage: A research brief published by the Institute for Energy Economics and Financial Analysis (IEEFA) concludes that the abrupt recent shutdown of the Petra Nova coal-fired carbon capture plant in Texas should be seen as a strong signal for investors to avoid such projects.

Le Référendum d’initiative citoyenne (RIC) ne répond pas seulement au désir légitime des citoyens d’être plus souvent consultés : il leur donne à la fois le choix des réponses et celui des questions. En ce sens, il accomplit pleinement le rêve d’une démocratie directe reconnue en droit depuis la Révolution, mais toujours savamment corsetée, voire empêchée. Les risques associés à cette procédure sont cependant nombreux et doivent être pris en compte : affaiblissement des autorités démocratiquement élues, multiplication de consultations aux effets potentiellement incontrôlables et contradictoires, manque de délibération préparatoire au vote, forte exposition à toutes sortes de manœuvres démagogiques...
