L'aviation commerciale est exigeante pour les compagnies établies, il est donc normal que les transporteurs ultra low-cost rencontrent aussi des difficultés.

Cela fait maintenant sept ans que le registre public d’information environnementale se fait attendre.

La startup Commonwealth Fusion Systems a annoncé la construction de la première centrale nucléaire dédiée à la fusion, dimensionnée pour alimenter un...

Alors que se profile le durcissement des limites de CO2 pour les constructeurs, les ventes d'électriques sont loin du compte pour atteindre l'objectif.

Un aéroport neutre en carbone c’est comme une kalashnikov de commerce équitable. Nous sommes en pleine urgence écologique, et les

As a record number of Americans travel this Thanksgiving weekend, some may notice how some airports are branding themselves as sustainable and environmentally-friendly. But that's not always the full story. Here's what to know about airport "greenwashing."

The tourism carbon footprint grew 2.3 times faster than the rest of the economy, reaching nearly 9% of global emissions by 2019. Rapid tourism demand growth (3.8% per year) has outpaced energy efficiency gains among businesses (0.3% per year).

Background Airport personnel are at risk of occupational exposure to jet engine emissions, which similarly to diesel exhaust emissions include volatile organic compounds and particulate matter consisting of an inorganic carbon core with associated polycyclic aromatic hydrocarbons, and metals. Diesel exhaust is classified as carcinogenic and the particulate fraction has in itself been linked to several adverse health effects including cancer. Method In this review, we summarize the available scientific literature covering human health effects of exposure to airport emissions, both in occupational settings and for residents living close to airports. We also report the findings from the limited scientific mechanistic studies of jet engine emissions in animal and cell models. Results Jet engine emissions contain large amounts of nano-sized particles, which are particularly prone to reach the lower airways upon inhalation. Size of particles and emission levels depend on type of aircraft, engine conditions, and fuel type, as well as on operation modes. Exposure to jet engine emissions is reported to be associated with biomarkers of exposure as well as biomarkers of effect among airport personnel, especially in ground-support functions. Proximity to running jet engines or to the airport as such for residential areas is associated with increased exposure and with increased risk of disease, increased hospital admissions and self-reported lung symptoms. Conclusion We conclude that though the literature is scarce and with low consistency in methods and measured biomarkers, there is evidence that jet engine emissions have physicochemical properties similar to diesel exhaust particles, and that exposure to jet engine emissions is associated with similar adverse health effects as exposure to diesel exhaust particles and other traffic emissions.

La fusion nucléaire, longtemps considérée comme le Saint Graal de la production énergétique, est sur le point de franchir une étape cruciale avec le développement du premier réacteur à fusion commerciale au monde. Situé à Chesterfield County en Virginie, ce projet ambitieux pourrait non seulement transformer notre manière de produire de l'électricité, mais aussi révolutionner

Selon une nouvelle étude, notre planète pourrait cacher dans ses entrailles d’énormes quantités d’hydrogène. S’ils étaient exploités, ces gisements pourraient assurer l’avenir énergétique de la Terre pendant des centaines, voire des milliers d’années.
