Farming seaweed, changing ocean chemistry, breeding corals and restoring mangroves could help fight climate change – if assessed and managed responsibly.

Cette réforme, qui devra passer par une phase de consultation publique, devrait notamment entraîner une vaste dérégulation du secteur automobile.

Le gouvernement de Donald Trump s'apprête à renverser la décision qui sert de fondation à la lutte contre les émissions de gaz à effet de serre aux États-Unis, deuxième plus gros émetteur mondial. […] En 1970, le Congrès américain a donné, via le Clean Air Act, le pouvoir à l'Agence de protection de l'environnement (EPA) de réguler "la pollution de l'air qui peut raisonnablement mettre en danger la santé publique".

Clean-energy sectors drove a quarter of the country’s gross domestic product (GDP) growth in 2024 and have overtaken real-estate sales in value. The new sector-by-sector analysis for Carbon Brief, based on official figures, industry data and analyst reports, shows the growing role of clean technology in China’s economy – particularly the so-called “new three” industries, namely, solar, electric vehicles (EVs) and batteries.

We develop roadmaps to transform the all-purpose energy infrastructures (electricity, transportation, heating/cooling, industry, agriculture/forestry/fishing) of 139 countries to ones powered by wind, water, and sunlight (WWS). The roadmaps envision 80% conversion by 2030 and 100% by 2050. WWS not only replaces business-as-usual (BAU) power, but also reduces it ∼42.5% because the work: energy ratio of WWS electricity exceeds that of combustion (23.0%), WWS requires no mining, transporting, or processing of fuels (12.6%), and WWS end-use efficiency is assumed to exceed that of BAU (6.9%). Converting may create ∼24.3 million more permanent, full-time jobs than jobs lost. It may avoid ∼4.6 million/year premature air-pollution deaths today and ∼3.5 million/year in 2050; ∼$22.8 trillion/year (12.7 ¢/kWh-BAU-all-energy) in 2050 air-pollution costs; and ∼$28.5 trillion/year (15.8 ¢/kWh-BAU-all-energy) in 2050 climate costs. Transitioning should also stabilize energy prices because fuel costs are zero, reduce power d

How ‘corporate disclosures’ are supposed to help Earth’s biodiversity.

C’est une habitude. Sans qu’on s’en rende compte, on n’y pense même plus. On flâne sous la douche, on lave la vaisselle en écoutant la radio, on lance une machine de linge, puis on tire la chasse après un passage aux toilettes. L’eau qu’on utilise s’en va ensuite dans l’égout et termine dans une station d’épuration proche de chez nous. Là-bas, elle passe par différents bassins pour être nettoyée. Au bout du processus, d’un côté, il y a l’eau claire rejetée dans les cours d’eau ; de l’autre, il reste une matière organique, dont on ne parle pas souvent, un résidu solide qu’on appelle boue d’épuration.

Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into oceans based on waste management, population density and hydrological information. Our model is calibrated against measurements available in the literature. We estimate that between 1.15 and 2.41 million tonnes of plastic waste currently enters the ocean every year from rivers, with over 74% of emissions occurring between May and October. The top 20 polluting rivers, mostly located in Asia, account for 67% of the global total. The findings of this study provide baseline data for ocean plastic mass balance exercises, and assist in prioritizing future plastic debris monitoring and mitigation strategies. Rivers provide a m

Global investment in the clean energy transition grew by 17% in 2023, showing resilience despite geopolitical tensions, high interest rates, and inflation. But was it enough to keep the world on track to hit net zero by 2050? To answer this question, we compare 2023 clean energy investment by sector with what’s annually needed to reach net zero by 2050, in partnership with the National Public Utilities Council.

Donderdag werd aan de Scheldeoevers in Hoboken een nieuwe samenwerking gelanceerd tussen River Cleanup en de Vlaamse Instelling voor Technologisch Onderzoek (VITO). Burgers worden opgeroepen om met drones het zwerfvuil langs de Schelde te spotten en zo hotspots in kaart te brengen. Artificiële intelligentie combineert de beelden, zodat nadien gericht opgeruimd kan worden.
