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.
Lancée en 2013, l’organisation à but lucratif The Ocean Cleanup a pour objectif de nettoyer les océans des déchets plastiques.
Een meerderheid van de Belgen zet plasticvervuiling in zijn top drie van grootste milieuproblemen, maar weet niet goed waar ze zelf kunnen helpen. Een gemiste kans, zegt de Belgische organisatie River Cleanup, want er is veel dat we kunnen doen.
Quels sont les pays qui rejettent le plus de plastique dans l'océan ? Pourquoi ? Qu'est-ce que cela signifie pour les solutions de lutte contre la pollution plastique ? Voici un regard de côté pour comprendre l'ampleur et les moteurs de la pollution plastique océanique, afin de mettre en œuvre les interventions les plus efficaces pour la réduire.

This study evaluates how Europe can fulfil its goal of “achieving resource security” and “reducing strategic dependencies” for its energy transition metals, through a demand, supply, and sustainability assessment of the Green Deal and its resource needs.
La République démocratique du Congo a mis aux enchères 27 blocs pétroliers et 3 blocs gaziers. Une décision qui, avertissent les ONG de défense de l’environnement, peut avoir des conséquences catastrophiques pour la biodiversité et les communautés locales.
Ember modelling of least-cost power system pathways reveals that a clean power system (70-80% wind and solar) by 2035 should be at the core of energy planning for a net-zero continent by mid-century.
Countries should move from coal to renewable energy without shifting to gas as a “transition” fuel to save money, as high gas prices and market volatility have made the fossil fuel an expensive option, analysis has found. Natural gas has long been touted as a “transition” fuel for economies dependent on coal for their power needs, as it has lower carbon dioxide emissions than coal but requires similar centralised infrastructure, and gas-fired power stations take only a couple of years to build. Earlier this year, before Russia invaded Ukraine, the European Commission angered green campaigners by including gas as a “bridge” to clean energy in its guidebook for green investment.
Metals will play a central role in successfully building Europe’s clean technology value chains and meeting the EU’s 2050 climate-neutrality goal. In the wake of supply disruptions from the COVID-19 pandemic and Russia's invasion of Ukraine, Europe’s lack of resilience for its growing metals needs has become a strategic concern. This study evaluates how Europe can fulfil its goal of “achieving resource security” and “reducing strategic dependencies” for its energy transition metals, through a demand, supply, and sustainability assessment of the EU Green Deal and its resource needs . It concludes that Europe has a window of opportunity to lay the foundation for a higher level of strate- gic autonomy and sustainability for its strategic metals through optimised recycling, domestic value chain investment, and more active global sourcing. But firm action is needed soon to avoid bottlenecks for several materials that risk being in global short supply at the end of this decade.
SACRAMENTO -- Data from the California Energy Commission (CEC) shows that 59 percent of the state’s electricity came from renewable and zero-carbon sources in 2020. The CEC estimates that in 2020, 34.5 percent of the state’s retail electricity sales were served by Renewables Portfolio Standard (RPS)-eligible sources such as solar and wind. When sources of zero-carbon energy such as large hydroelectric generation and nuclear are included, 59 percent of the state’s retail electricity sales came from non-fossil fuel sources in 2020. In 2019, over 60 percent of the state’s electricity came from renewable and zero-carbon sources. The decrease in 2020 is due to decline in hydroelectric generation caused by severe drought, as well as pandemic-related delays to new renewable energy projects.

The IEA examines the full spectrum of energy issues including oil, gas and coal supply and demand, renewable energy technologies, electricity markets, energy efficiency, access to energy, demand side management and much more. Through its work, the IEA advocates policies that will enhance the reliability, affordability and sustainability of energy in its 30 member countries, 8 association countries and beyond.
L’association The Ocean Cleanup, fondée par Boyan Slat, un inventeur néerlandais, a pour objectif d’éliminer 90 % du plastique flottant de l’océan d’ici 2040. Cet objectif ambitieux semblait à la fois réalisable et hors de portée en raison des différents résultats des systèmes de nettoyage. Mais désormais, il semble que le nouvel appareil 002 de l’association, surnommé Jenny, tienne ses promesses.
Human rights council also appoints special rapporteur to monitor impact of climate crisis on rights
The Ocean Cleanup, une organisation à but non lucratif connue pour ses efforts visant à nettoyer les océans de nos déchets, s’attaque désormais au vortex de déchets du Pacifique nord, une énorme masse d’ordures située dans l’océan Pacifique entre Hawaï et la Californie.
The huge amount of money poured into the recovery from the pandemic—around $16 trillion, by the latest count—could have helped launch the world on a path to cut emissions quickly enough to meet the goals of the Paris climate agreement. But only around 2% of the spending is going to clean energy so far,
Fondée par le Belge Thomas de Groote, l'association se mobilise chaque année pour un grand nettoyage de fleuves et rivières, mais surtout pour sensibiliser les citoyennes et les citoyens aux conséquences de la pollution plastique.
Electrical blackouts like the ones in California are becoming more common. So are heat waves. A new study published in the journal of the National Institute of Health attempts to predict what will happen when both occur at the same time.

Unlike carbon dioxide, atmospheric methane concentrations are rising faster than at any time in the past two decades. The fossil fuel, agriculture and waste sectors are equally responsible.

Rivers are a major source of plastic waste in the oceans. We estimate that 1000 rivers, are accountable for nearly 80% of global annual riverine plastic emissions, which range between 0.8 – 2.7 million metric tons per year, with small urban rivers amongst the most polluting.

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
