Global carbon emissions and decarbonization in 2025 Nature Reviews Earth & Environment (2026)Cite this article Global CO2 emissions from fossil fuel combustion and industrial processes increased by +0.7% within 2025. However, large-scale deployment of clean electricity sources during the year avoided 10.3 Gt of global CO2 emissions, so that power sector emissions declined by –0.9% relative to 2024. As the remaining carbon budget for limiting global warming to 1.5 °C is projected to be exhausted by 2029 at a 50% likelihood, further accelerating the shift away from fossil fuels is essential for staying within the 2 °C temperature rise limit. Key points:- Global emissions reached a record of 37.2 Gt CO2 in 2025, yet the annual growth rate has flattened to 0.7%. Global power sector emissions dropped by –0.9%, indicating a structural decoupling of electricity demand from fossil fuel consumption. China and India entered an emission plateau owing to massive renewable expansion, whereas th...

As of April 2026, the green hydrogen dream is indeed slipping further out of reach due to a convergence of high production costs, stalled infrastructure projects, and a lack of firm buyer demand, turning what was hailed as a "fuel of the future" into a reality check focused on economic viability.  Here are the key reasons why the dream is stalling:- Costs Remain Too High: - Despite technological advancements, the cost of producing green hydrogen (via electrolysis) remains significantly higher than fossil-fuel-based "grey" hydrogen. High renewable energy prices and expensive electrolyzer hardware mean competitive pricing isn't expected before the 2030s. Projects Are Stalling (The "Valley of Death"): - While project pipelines look impressive, only a tiny fraction (around 4%) of announced projects have reached  final investment decision (FID) or are currently operational, as investors balk at the high risk and low immediate returns. Lack of Demand/Custome...

Multiple western disturbances from the Mediterranean are forecast to hit India starting April 27, 2026, bringing much-needed rain, thunderstorms, and dust storms to North and East India. This system will break the intense, ongoing heatwave, with temperatures predicted to dip below 42∘C by April 29.  Key Details on the Impending Weather Change: Timing:-  Isolated rain and dust storms begin as early as the evening of April 27, intensifying between April 28 and April 30. Affected Areas:-  Delhi, Punjab, Haryana, Rajasthan, and parts of East India are expected to see significant weather changes. Impact: - The disturbances will bring strong winds, cloud cover, and rain, significantly decreasing the ongoing heatwave. Specifics: - Some areas might even see squalls reaching speeds of 70 kmph. Result: - A welcome dip in temperatures is expected from April 29 onward, offering a temporary reprieve from scorching conditions.  This back-to-back approach of disturbances is conside...

The Uttar Pradesh (UP) government has taken several key initiatives for environment protection, focusing on mass plantation, industrial pollution control, and Ganga rejuvenation under the Uttar Pradesh State Action Plan on Climate Change (2021-2030).  Key actions include: Massive Afforestation & Green Cover:-  The state reported planting 37.21 crore saplings in 2025 alone under the "Ek Ped Maa Ke Naam" campaign.  The government claims an increase of 5 lakh acres of green cover since 2017, with a high survival rate for plantation projects. Ganga and River Protection:-  The "Namami Gange" program includes sewerage treatment infrastructure, industrial effluent monitoring, riverfront development, and afforestation. The state has established the UP State Ganga River Conservation Authority to control pollution in Ganga and its tributaries. Air Quality Management: - Under the National Clean Air Program (NCAP), the government is promoting e-vehicles, CNG vehicles, and m...

Breaking through the bottleneck in rare earth (RE) wastewater treatment—typically characterized by low-concentration elements, high acidity, and co-existing heavy metals/radioactive contaminants—requires shifting from traditional chemical precipitation to advanced, selective, and eco-friendly technologies.  Key strategies to overcome current limitations include leveraging bio-based recovery, AI-optimized processes, and integrated separation techniques to turn hazardous wastewater into a resource-recovery stream.  1 ) Advanced Separation & Recovery Technologies Selective Membrane Filtration: - Hollow Fiber Supported Liquid Membranes (HFSLM) are emerging as a pilot-scale solution, achieving >90% rare earth recovery while reducing solvent consumption by 1–2 orders of magnitude compared to traditional mixer-settlers. Functionalized Adsorbents: - Utilizing nanofiber adsorbents or  mechanically activated talc allows for high-efficiency, low-cost removal of REEs from dilu...

India has solidified its position as a global renewable energy leader, with solar power capacity exceeding 150 GW by March 2026 and total renewable capacity crossing 250 GW. Surpassing Japan to become the world's third-largest solar producer, India achieved over 50% renewable capacity in its energy mix, meeting COP26 goals years ahead of schedule.  Key Takeaways: India's Renewable Energy Surge Solar Dominance: - India added a record 44.6 GW of solar capacity in FY 2025–26, driven by aggressive domestic manufacturing (74 GW capacity) and solar park expansion. Global Position: - Ranked 4th globally in total Renewable Energy Installed Capacity and 3rd in solar power capacity, actively surpassing Japan and set to exceed the US. Record Generation:-  In 2025, renewable power generation increased by 98 TWh, with  solar (37% increase) and  wind (28% increase) setting new records, contributing to a significant drop in coal-based power generation. Infrastructure & Policy: ...
