Un confronto tra due tra le tipologie più utilizzate, l’acciaio al carbonio S235JR e l’acciaio inossidabile AISI 304, permette di chiarire rapidamente differenze, vantaggi e principali applicazioni di queste famiglie di materiali

    Ginevra 2025: i negoziati ONU sulla plastica si chiudono senza accordo

    By

    I negoziati per un trattato globale contro l’inquinamento da plastica sono falliti per la seconda volta. Dopo Busan (dicembre 2024), anche Ginevra (5-15 agosto 2025) si è conclusa senza accordo tra 183 Stati. Quattro divisioni hanno impedito il consenso: ambito del trattato (ciclo completo vs. solo rifiuti), controlli sulla produzione, finanziamento e processo decisionale. La gestione controversa e quattro testi negoziali diversi hanno aggravato la crisi. Il futuro dei negoziati resta incerto tra ripresa INC, nuovo mandato UNEA o coalizioni volenterose.

    What’s changing in sustainability? Monthly update ( April 15-May 15, 2025)

    By

    Stay informed on the latest sustainability developments with this monthly update, covering pivotal shifts in environmental policy, energy efficiency, and regulatory frameworks. Across Europe, policymakers are recalibrating timelines and relaxing environmental requirements to balance climate goals with economic pressures, from postponing key directives to easing farm and auto emissions standards. Meanwhile, Africa is advancing bold initiatives in green building, ESG integration, and regional energy harmonization, while grappling with funding disputes and environmental vulnerabilities. In Asia and Latin America, countries are tightening sustainability reporting and fostering clean energy and circular economies, often led by grassroots and indigenous leadership. Globally, momentum is building for more unified action, as seen in groundbreaking international shipping regulations and evolving frameworks in Australia and Canada.

    Southeast Asia moves toward SAF exports: roadmaps and opportunities

    By

    A recent joint ASEAN–Canada study highlights Southeast Asia’s potential to become a global hub for sustainable aviation fuel (SAF) production. Countries such as Indonesia, Malaysia, the Philippines, Thailand, and Vietnam have access to a wide range of agricultural biomass — including rice straw, palm oil residues, and non-food-grade coconuts — suitable for SAF production.

    Thanks to growing public and private investments, the region could not only meet its own demand but also become a net exporter by 2040, with Japan and South Korea identified as key markets. National roadmaps set blending targets of up to 47% by 2050.

    Beyond emission reductions, the SAF value chain offers significant employment opportunities and could supply around 12% of global demand. This development strengthens ASEAN’s strategic role in the energy transition and the decarbonization of air transport.

    The EU agreed on new plastic pellet pollution regulations, while the shipping industry will now pay for vessel carbon emissions. The Czech Republic strengthened its “polluter pays” principle, Germany adopted its Sustainability Strategy 2025, and Italy launched a €232 million renewable energy program. Brazil updated ambitious climate targets ahead of hosting COP30, the UK introduced steep fines for greenwashing, and Southeast Asia shows potential as a hub for Sustainable Aviation Fuel production. UNEP’s Champions of the Earth Award nominations remain open until April 30.

    On 8 April 2025, the Council of the EU and the European Parliament reached a provisional agreement on a new regulation to prevent the loss of plastic pellets (microplastic pollution) across the supply chain. The rules will mandate stricter handling and cleanup measures for plastic pellet spills on land and at sea. This EU-wide measure aims to reduce the 52 140 and 184 290 tonnes of pellets lost to the environment each year (estimation based on 2019 data).

    CO₂ Batteries: the new frontier of energy storage in India

    India Bets on CO₂ Batteries: The Next Frontier in Sustainable Energy Storage

    India is set to redefine energy storage with the launch of its first CO₂ battery, a collaboration between NTPC and Italian innovator Energy Dome. The 160 MWh project in Kudgi, Karnataka, marks a major milestone in Long Duration Energy Storage (LDES) technology. Using a closed-loop thermodynamic cycle powered by carbon dioxide, this system delivers high efficiency, long lifespan, and full sustainability—without relying on lithium, cobalt, or rare earth materials. It’s a game-changing solution to make renewable energy sources reliable and dispatchable, while boosting India’s power grid resilience and supporting local industrial growth.
