Evolution of the RTI Act, 2005
-
The RTI Act, 2005 marked a major step in strengthening freedom of information in India. The Bill was introduced in Parliament in December 2004, passed by the Lok Sabha on 11 May 2005 and the Rajya Sabha on the following day, before finally coming into effect on 12 October 2005.
-
Interestingly, the Union government had earlier enacted the Freedom of Information (FOI) Act, 2002, but as rules were never notified, it remained non-operational. The RTI Act was thus prepared afresh and implemented in 2005.
-
With this law, India joined a select group of nations having similar legislation. The first such law was enacted in Sweden in 1766, followed by the US in 1966, and the UK in 2005. Today, nearly 120 countries across the world have comparable provisions.
-
The RTI Act empowered citizens to seek information from public authorities, thereby making governments more accountable and transparent. It became a vital instrument for citizen empowerment and participatory democracy
Central and State Information Commissions
-
To enforce its provisions, the Act established the Central Information Commission (CIC) and corresponding State Information Commissions to hear complaints and appeals.
-
As per Section 12, the CIC is composed of a Chief Information Commissioner (CIC) and up to 10 Information Commissioners (ICs), depending on requirements.
-
Originally, the Act provided CIC and ICs with status and service conditions similar to that of members of the Election Commission of India, including a fixed five-year tenure.
-
However, the 2019 Amendment diluted this by giving the Union government discretion over their tenure, salary, and terms of service, thereby reducing their autonomy.
-
The CIC’s jurisdiction covers all Central Public Authorities. Its functions, outlined in Sections 18, 19, 20 and 25, include:
-
Deciding second appeals for information,
-
Directing proactive disclosure and record maintenance,
-
Handling complaints of denied access to information,
-
Imposing penalties on defaulters, and
-
Preparing annual reports on implementation.
- Importantly, the CIC cannot interfere in matters under the State Information Commissions, and no appeal lies to the CIC against their orders.
- According to Section 2(f), information may include records, files, memos, e-mails, circulars, reports, contracts, samples, electronic data, and even information held by private bodies if accessible by a public authority under existing laws
- Certain intelligence and security agencies listed in the Second Schedule are exempted from sharing information. However, this protection does not apply in cases involving corruption or human rights violations.

Alternatives to Ethanol in Biofuels
While ethanol is the most common biofuel, alternatives such as butanol and acetone-butanol-ethanol (ABE) mixtures are being explored as potentially more efficient fuels. The interest in these substitutes is largely driven by the global goal of reducing dependence on fossil fuels. However, biofuels are usually seen as one element in a broader renewable energy mix, which also includes solar, wind, geothermal, hydro, and tidal energy.
An economic challenge persists since biofuel production often clashes with food production and export revenues. For instance, Brazil earns more from soybean exports than from biodiesel derived from soybean oil.
Butanol and ABE Fuels
Butanol and ABE solvents are produced naturally by solventogenic Clostridia, bacteria that ferment a wide variety of cellulose- and hemicellulose-based feedstocks. Notably, Clostridium beijerinckii BA101 is recognized as a strain capable of producing high yields of butanol with greater tolerance.
Recovering ABE products is more complex than ethanol production, as it involves separating multiple solvents. Researchers are experimenting with improved processing techniques. For example, Japanese studies found that adding glucose to municipal wastewater treatment systems boosted butanol output while also reducing sludge sent to landfills.
Other microbes, like Vibrio furnessi, can produce hydrocarbons such as octadecane directly, providing a microbial pathway to “ready-to-use” fuels. Additionally, glycerol, a byproduct of ethanol fermentation, can serve as feedstock for producing liquid alkanes via the Fischer-Tropsch process at high temperatures with platinum catalysts.
Biohydrogen
- The International Energy Agency (IEA) identifies hydrogen as a vital clean energy carrier for transport. Hydrogen fuel cells achieve about 50% conversion efficiency, higher than most thermal power systems.
- Biohydrogen can be generated through acid fermentation of glucose, yielding hydrogen alongside ABE solvents or carboxylic acids.
- Clostridium species are major hydrogen producers, though Bacillus and thermophilic bacteria like Caldicellulosiruptor saccharolyticus have also been used, with the latter achieving nearly 92% of the theoretical yield.
- Some in vitro systems even achieve 11 moles of Hâ‚‚ per mole of glucose, far higher than microbial fermentation
Photosynthetic Hydrogen
- Photosynthetic hydrogen is carbon-neutral, needing only sunlight, water, COâ‚‚, and chlorophyll. Some cyanobacteria separate oxygen and hydrogen production either spatially (different cells) or temporally (day vs. night).
- Techniques like mutagenesis of hydrogenase enzymes are being tested to reduce oxygen sensitivity. For example, Chlamydomonas reinhardtii, when deprived of sulfur, can continue hydrogen production for about 100 hours.
- Similarly, thermophilic cyanobacteria can sustain photo-hydrogen output for weeks, requiring minimal light in a process known as photo-fermentation
Biodiesel
- Biodiesel is produced through transesterification of animal or plant fats (triglycerides) with methanol, often using potassium hydroxide as a catalyst. Newer, cleaner catalysts include amorphous carbon and SiOâ‚‚-ZrOâ‚‚ ion exchange resins.
- Feedstocks with high free fatty acid content, such as Jatropha oil, can cause saponification, lowering efficiency.
- While lipase enzymes provide a greener route for transesterification, they are costly and unstable in methanol.
- Biodiesel is estimated to cut COâ‚‚ emissions by around 55% and reduce SOâ‚‚, CO, and particulates, but it may increase NOx and hydrocarbon emissions. Combustion soot from biodiesel also raises concerns about mutagenic effects.
Synthetic Liquid Fuels
- Liquid fuels can also be synthesized through pyrolysis, which produces syngas (CO + Hâ‚‚). With metal catalysts, syngas can be converted into liquid fuels.
- Using lignocellulosic biomass for pyrolysis could reduce fossil fuel emissions by up to 90% and lessen pressure on agricultural land, but current costs make it less competitive than petroleum fuels.
- If made cost-effective, these fuels may outperform blends like E85 (ethanol-gasoline) in lowering COâ‚‚ and particulate emissions.
Microalgal Biodiesel
- Microalgae offer much higher oil yields—up to 100 times more than traditional oilseed crops. They can be cultivated in ponds, even using flue gas COâ‚‚ from thermal plants. It is estimated that just 5% of U.S. land area under algae could meet global petroleum demand without affecting farmland.
- Species like Chlorella protothecoides and Scenedesmus obliquus can produce large amounts of triglycerides under heterotrophic cultivation using corn hydrolysates, functioning much like fermentation in the dark.
Sustainability Concerns
The long-term viability of biofuels depends on whether feedstocks are truly renewable and whether biomass supply is abundant. In reality, both are constrained.
Biofuel farming often harms sustainability:
-
Topsoil regeneration is extremely slow (1 cm in 300–400 years).
-
Groundwater recharge is limited.
-
Fertilizers depend on fossil fuels.
-
Mechanized farming depletes soil quality.

Answer (A)
The National Policy on Biofuels (2018) allows the use of a wide range of surplus food grains and other feedstocks for ethanol production, but only in case of surplus or non-edible/ damaged stock. âœ”ï¸ Allowed feedstocks include:
⌠Not allowed as feedstocks:

Nearly 180 countries have been unable to reach a consensus on creating a binding international treaty to curb plastic pollution, with negotiations in Geneva ending in deadlock. Although the United Nations Environment Programme (UNEP) has already passed a resolution acknowledging the need for such an agreement, only a legally binding treaty would compel nations to adopt concrete measures.
Challenges posed by plastics
Plastic is the defining material of the modern industrial and consumer-driven economy. Chemically, plastics are made of polymers, which may occur naturally—like cellulose and lignin—or be artificially synthesised in laboratories.- Plastics derived from fossil fuels, molded into a wide range of products, have become indispensable to daily life. They are used in critical applications such as aviation and healthcare, as well as in packaging, decorations, and other everyday items.
- Their popularity stems from their versatility and low production cost compared to alternatives like glass or aluminum. However, this same accessibility has made plastic one of the most common pollutants, highlighting the failures of global waste management systems.
- Another problem is the durability of plastics. They are mixtures containing polymers, monomers, and numerous additives. Over 16,000 chemicals can be present in plastic products, and information about the effects of more than 10,000 of them remains scarce.
- A study in Nature highlighted that over 4,000 potentially harmful chemicals may exist in common types of plastics such as PVC, polyethylene, PET, and polyurethane.
- Since most of these substances are synthetic and non-biodegradable, they persist in the environment and can infiltrate ecosystems and living organisms.
- Initially, public attention was on recycling and disposal, but scientific research increasingly points to the risk of harmful chemicals from plastics entering food chains, water systems, and even human bodies.
Evidence of health risks
- Many plastics are made from petrochemical derivatives like ethylene, propylene, and styrene. Their production involves numerous other compounds such as bisphenols, phthalates, PCBs, PBDEs, and PFAS. These substances are widely used in items ranging from food packaging and baby toys to textiles, electronics, cosmetics, and medical products.
- For decades, researchers have examined whether exposure to such chemicals contributes to health problems. Recently, Boston College in the U.S. and the Minderoo Foundation in Australia compiled findings from about 1,100 studies covering 1.1 million people.
- These studies have linked exposure to plastics-related chemicals with altered thyroid function, hypertension, cancers of the kidney and testis, and gestational diabetes. However, most studies are associative rather than conclusive, making it difficult to isolate plastics as the sole cause.
- The gold standard for such evidence is long-term longitudinal research, which tracks individuals over time to directly assess the impact of reduced exposure. Some such studies are underway, but results will take time.
- Meanwhile, microplastics—tiny particles smaller than five millimetres—have been detected in blood, breast milk, the placenta, and even bone marrow. Although their exact health effects are still uncertain, they are suspected of contributing to a variety of disorders.
India’s approach to plastics
- In India, nearly 20 States have banned single-use plastics—items that are the hardest to recycle and have limited reuse potential. The government has also introduced regulatory measures requiring companies to collect back a portion of the plastics they generate.
- Despite these steps, implementation has been weak, and the health risks posed by plastics are yet to receive serious recognition in policy.
- At the global level, India and several other countries have opposed including health-related discussions in the proposed plastics treaty, arguing that such matters should fall under the jurisdiction of the World Health Organization. Consequently, for India, plastics continue to be treated largely as a waste management challenge rather than a broader public health threat
1.In India, ‘extend producer responsibility’ was introduced as an important feature in which of the following? (UPSC CSE 2019)
(a) The Bio-medical Waste (Management and Handling) Rules, 1998
(b) The Recycled Plastic (Manufacturing and Usage) Rules, 1999
(c) The e-Waste (Management and Handling) Rules, 2011
(d) The Food Safety and Standard Regulations, 2011
|
Answer (c)
Extended Producer Responsibility (EPR) is a policy approach where producers are made responsible for the collection, recycling, and environmentally safe disposal of the products they manufacture once they reach the end of their life cycle. In India, the concept of EPR was formally introduced under the E-Waste (Management and Handling) Rules, 2011, making manufacturers of electrical and electronic equipment accountable for managing the waste generated by their products. |
Flash Floods in Jammu & Kashmir
- At least 65 people lost their lives in a devastating flash flood triggered by heavy rainfall in Kishtwar district of Jammu & Kashmir on Thursday.
- The disaster struck Chasoti village, the last road-accessible settlement on the route to the Machail Mata temple, with over 50 people still reported missing.
- Although scientists avoid linking any single weather disaster directly to climate change, they emphasize that the frequency and intensity of flash floods, wildfires, and similar events are increasing worldwide due to rising global temperatures and shifting climate patterns.
- Like in other regions, Jammu & Kashmir has seen a growing number of extreme weather events, resulting in thousands of deaths in recent years.
Key Drivers of Extreme Weather in J&K
-
Rising Temperatures
-
Situated in the western Himalayas, Jammu & Kashmir has experienced twice the rate of warming compared to the Indian subcontinent since 2000 (Global Warming — A Concerning Component of Climate Change, 2023).
-
Warmer air holds more moisture — roughly 7% more for every 1°C increase — which results in heavier and more frequent rainfall, prolonging wet spells and raising flood risks.
-
Rising temperatures have also accelerated glacier retreat, leading to the formation of more glacial lakes. When these lakes breach, they release large volumes of water, triggering catastrophic downstream floods.
-
-
Changing Western Disturbances
-
The altered behavior of Western Disturbances has reshaped precipitation trends in the region, contributing to irregular and extreme rainfall events.
-
-
Fragile Topography
-
The mountainous terrain makes J&K naturally vulnerable to flash floods and landslides, amplifying the impact of extreme weather events
-
- Experts believe that the increasing instances of flash floods and heavy rainfall in Jammu & Kashmir may be linked to global warming–driven changes in western disturbances.
- These disturbances are eastward-moving wind systems that originate beyond Afghanistan and Iran, carrying moisture from the Mediterranean, Black, Caspian, and Arabian Seas.
- Traditionally, western disturbances were most active during the winter months (December–March), but in recent years, they have started influencing weather beyond the winter season.
- This shift has heightened the risk of intense rainfall and flooding across the Himalayan states, particularly in J&K, where the mountainous terrain increases its vulnerability to such extreme events

India’s fossils are at high risk of being sold abroad
For Preliminary Examination: Fossil Fuels, Renewable energy
For Mains Examination: GS III - Environment and Ecology
Context:
In Western India, some of the country’s richest fossil beds lie inside open coal mines. It is gruelling work for palaeontologists with long days under a haze of dust, the deafening hammering of tools, and nights in small-town hotels with basic comforts.

What are Fossil fuels?
Key takeaways:
- India has long been celebrated for its diverse cultural heritage, but it is equally rich in natural heritage that dates back millions of years. Among the treasures hidden in its soil are fossils—remnants of ancient plants, animals, and early life forms that provide crucial evidence for understanding the evolution of life and Earth’s geological history.
- Yet, like many of India’s antiquities and relics, fossils face the growing threat of illegal collection, trafficking, and smuggling to foreign markets where collectors, researchers, and private museums are willing to pay staggering amounts.
- This silent erosion of India’s natural heritage raises pressing questions about conservation, regulation, and the balance between scientific study and commercial exploitation.
- India is home to some of the world’s most remarkable fossil sites. From the dinosaur-bearing rocks of Gujarat and Madhya Pradesh, to the stromatolite fossils in Rajasthan that date back billions of years, to plant fossils in Jharkhand and the Siwalik Hills famous for mammalian remains, the country possesses a geological record of immense value.
- These fossils are not merely curiosities; they serve as primary evidence for reconstructing the Earth’s climatic, ecological, and biological past.
- For instance, the discovery of Rajasaurus narmadensis, a carnivorous dinosaur from the Cretaceous period in the Narmada Valley, has helped paleontologists trace evolutionary patterns unique to the Indian subcontinent.
- Likewise, fossilized plants from the Gondwana formations shed light on the ancient supercontinent’s breakup and India’s geological journey.
- However, just as idols from temples and sculptures from ancient sites have been smuggled abroad over decades, fossils too are quietly slipping out of the country. In global black markets, the demand for fossils has surged.
- Dinosaur eggs, fossilized skeletons, or even smaller specimens such as ammonites and trilobites fetch high prices from private collectors who often regard them as status symbols. Unlike cultural relics, where the Archaeological Survey of India and customs officials are alert to illicit trade, fossils have traditionally not received the same level of attention.
- This regulatory gap leaves fossil-rich regions vulnerable to looting. Often, locals unaware of their scientific value dig out fossils and sell them to middlemen for meagre sums, while the specimens eventually end up in international auctions fetching thousands of dollars.
- The consequences of such fossil trafficking are grave. Once a fossil is illegally removed and shipped abroad, the scientific community loses not only the specimen but also the geological and environmental context in which it was found. Fossils derive their meaning from their stratigraphic position, surrounding sediments, and associations with other remains.
- When smuggled abroad, this crucial information is erased, rendering them less useful for serious research. Moreover, the nation is deprived of showcasing its natural heritage in museums where citizens, especially students, could learn about Earth’s history.
- Instead, these irreplaceable relics become objects of private display, inaccessible to the public and to scientists who might otherwise contribute to global paleontological knowledge.
- Part of the problem lies in inadequate legal protection. Fossils in India fall into an ambiguous category—they are neither fully covered under the Antiquities and Art Treasures Act, 1972, nor consistently protected under mining or forest laws.
- While the Geological Survey of India and certain state institutions attempt to monitor fossil-rich sites, they are often understaffed and lack enforcement capacity. Unlike wildlife trafficking, which is addressed under the Wildlife Protection Act, or antiquities smuggling, which is combated through cultural property laws, fossil smuggling does not receive comparable attention.
- Adding to this challenge is the growing commercialization of fossils worldwide. Fossil trade, especially in countries like the United States, has become legitimized through auctions and private sales, often blurring the line between scientific specimens and collectibles.
- This global demand incentivizes illegal excavation in fossil-rich but poorly monitored regions like India. Local poverty and lack of awareness only fuel the problem, as villagers may view fossils merely as stones with monetary value rather than priceless scientific records.
- Addressing this issue requires a multi-pronged approach. First, there is a need for clear legislation that classifies fossils as protected heritage, placing them under the same safeguards as archaeological relics.
- Second, awareness campaigns in fossil-rich regions can educate local communities about the importance of fossils, encouraging them to report discoveries rather than sell them.
- Third, investment in fossil parks, local museums, and scientific tourism could provide alternative sources of income for communities while ensuring that specimens remain in the country.
- Initiatives like the Ghughua Fossil Park in Madhya Pradesh, which displays plant fossils from 40 to 150 million years old, demonstrate the potential of conservation tied with education and tourism.
- Finally, stronger collaboration with customs authorities, Interpol, and international museums is needed to track and repatriate smuggled fossils, much like stolen antiquities.
- India stands at a crossroads. Just as the nation has begun to recover smuggled idols and ancient artefacts from abroad, it must also take steps to safeguard its natural relics that are equally irreplaceable.
- Fossils are not inert rocks; they are storytellers of deep time, chronicling evolutionary transitions, climatic shifts, and geological transformations. Allowing them to vanish into private collections abroad would not only deprive the country of scientific opportunities but also erode a vital part of its natural heritage.
- Protecting fossils, therefore, is not merely a task for scientists but a responsibility of the nation, for these remnants of life long past belong to all of humanity yet remain rooted in India’s soil
With reference to the Agreement at the UNFCCC Meeting in Paris in 2015, which of the following statements is/are correct? (UPSC 2016)
- The Agreement was signed by all the member countries of the UN and it will go into effect in 2017.
