Notes:
India recently signed agreements to supply 4.12 lakh tonnes of green hydrogen derivatives to Japan and Singapore. The Green Hydrogen Certification Scheme of India (GHCI) was launched simultaneously to ensure credible and transparent green hydrogen production. GHCI is India’s first certification framework to verify that hydrogen is produced exclusively using renewable energy. This certification ensures hydrogen is recognized as “green.” GHCI was launched by the Ministry of New and Renewable Energy (MNRE). The Bureau of Energy Efficiency (BEE) is the nodal agency for GHCI. It is supported by the National Green Hydrogen Mission.

Notes:
Under the Swachh Bharat Mission-Urban, Ghaziabad issued India’s first Certified Green Municipal Bond, raising ₹150 crore for a Tertiary Sewage Treatment Plant (TSTP). This bond marks a major shift towards sustainable urban infrastructure and financial innovation. The Tertiary Sewage Treatment Plant uses advanced Membrane Filtration Technologies like microfiltration, ultrafiltration, nanofiltration, and reverse osmosis (RO) to treat wastewater. The plant has a treatment capacity of 40 Million Litres per Day (MLD) and is linked to a 95 km pipeline network. It supplies treated water to over 1,400 industrial units, cutting dependence on freshwater sources.

Notes:
Researchers at the Institute of Nano Science and Technology (INST), Mohali, have found a new way to improve green hydrogen production. They created a special heterostructure using Copper Tungsten Oxide and Copper Oxide. This structure uses the Built-In Electric Field (BIEF) effect to boost the Hydrogen Evolution Reaction (HER). The Copper Tungsten Oxide nanoparticles are grown over a Cu(OH)₂ base, forming a p-n heterojunction with an uneven electronic setup. This BIEF helps in better proton adsorption and desorption. Green hydrogen, made from water using clean energy, is a pollution-free fuel of the future.

Notes:
Jal Shakti Minister C R Paatil held a review meeting on 30 April with the Wildlife Institute of India to assess the progress of the ‘Jalaj’ project. The ‘Jalaj’ project is a key initiative developed by the Ministry of Jal Shakti to support the rejuvenation of the Ganga River and biodiversity conservation. It involves setting up floating platforms on the Ganga River to promote livelihood activities for local communities. These platforms also raise awareness about conserving the river and its ecosystem. The project blends ecological restoration with sustainable development for Ganga-dependent populations.

Notes:
United Kingdom (UK)-based health charity Encephalitis International has launched a global campaign titled ‘Preventing Future Encephalitis: Climate Change and Infectious Disease’ to raise awareness about encephalitis and promote vaccination. Encephalitis is the inflammation of active brain tissues caused by infections or autoimmune responses, affecting over 1.5 million people globally every year. The campaign highlights how climate change increases encephalitis risk by creating conditions for disease-carrying vectors like mosquitoes and ticks to spread. India is among high-burden countries, with 1,548 cases of Japanese encephalitis reported in 2024 from 24 states and union territories.

Notes:
Vietnam hosts the United Nations (UN) Day of Vesak in 2025 from May 6 to 8 in Ho Chi Minh City. The United Nations Day of Vesak marks the birth, enlightenment, and passing away of Lord Buddha. In a historic first, the sacred Buddha Relic from Sarnath, India, will be sent to Vietnam for special exposition. The event is being organized by the Ministry of Culture, Government of India, along with the International Buddhist Confederation (IBC).

Notes:
The Prime Minister of India will officially inaugurate the Vizhinjam International Seaport in Kerala, marking a major milestone in global maritime connectivity for the state. Vizhinjam Port is located in Vizhinjam, a coastal town in Thiruvananthapuram district of Kerala. It is India’s first dedicated transshipment port and also the country’s first semi-automated port. The port is built at a cost of about ₹8,900 crore under the Public-Private Partnership (PPP) model and is operated by the Adani Group, while the Kerala government holds the majority stake. It has the deepest breakwater in India, nearly three kilometres long, with a natural draft of about 20 metres. The port features India’s first home-built, Artificial Intelligence (AI)-powered Vessel Traffic Management System, developed with Indian Institute of Technology (IIT) Madras.

Notes:
Archaeological Survey of India (ASI) recently found 11 Satavahana-era inscriptions in the Gundaram Forest of Telangana’s Peddapalli district. Two inscriptions mention the Chutu dynasty and a Satavahana prince named Kumāra Hakusiri. These inscriptions are written in early Brahmi script and show religious and political symbols. The Satavahana dynasty was founded by Simuka after the Mauryan Empire, around mid-1st century BCE. The word “Satavahana” in Prakrit means “driven by seven,” symbolizing the chariot of the Sun God. Their main regions were Andhra Pradesh, Telangana, and Maharashtra. They ruled from capitals like Pratishthana (Paithan) and Amaravati.

Notes:
At the recent World Audio Visual Entertainment Summit (WAVES) in Mumbai, the Prime Minister highlighted India’s growing Orange Economy driven by content, creativity and culture. The Orange Economy, also called the creative economy, covers sectors that are based on cultural and creative ideas. As per the United Nations Economic Network, it focuses on using creative assets to boost economic growth and development. It combines economic, cultural and social factors while linking with technology, intellectual property and tourism. It includes industries based on individual talent, skill and innovation that can generate jobs, income and cultural value.
