Selon une nouvelle étude de l’ONG Transport & Environment, les compagnies low-cost ont vu leurs émissions carbone s’envoler en 2023.

Europese lagekostenmaatschappijen als Ryanair en Wizz Air vervuilden in 2023 meer dan ooit. Ze stoten nu aanzienlijk meer uit dan tijdens de piek voor de coronapandemie.

Potential external cost savings associated with the reduction of animal-sourced foods remain poorly understood. Here we combine life cycle assessment principles and monetarization factors to estimate the monetary worth of damage to human health and ecosystems caused by the environmental impacts of food production. We find that, globally, approximately US$2 of production-related external costs were embedded in every dollar of food expenditure in 2018—corresponding to US$14.0 trillion of externalities. A dietary shift away from animal-sourced foods could greatly reduce these ‘hidden’ costs, saving up to US$7.3 trillion worth of production-related health burden and ecosystem degradation while curbing carbon emissions. By comparing the health effects of dietary change from the consumption versus the production of food, we also show that omitting the latter means underestimating the benefits of more plant-based diets. Our analysis reveals the substantial potential of dietary change, particularly in high and upper-

The world is experiencing unprecedented fuel price increases, energy blackmail between countries, up to 7 million air pollution deaths per year worldwide and one climate-related disaster after another. Critics contend that a switch to renewable energy to solve these problems will create unstable electricity grids and drive prices up further. However, a new study from my research group at Stanford University concludes that these problems can be solved in each of the 145 countries we examined — without blackouts and at low cost using almost all existing technologies.

Le motoriste britannique Rolls-Royce a annoncé mardi qu'il allait construire de petits réacteurs nucléaires "à bas coûts" au Royaume-Uni "à la suite d'une levée de fonds réussie" auprès d'un consortium d'investisseurs.
