Motorists will not be able to buy fuel in Delhi without a valid Pollution Under Control (PUC) certificate from October 25.

What is PUC Certificate?

• The PUC certificate is a document that any person driving a motor vehicle can be asked to produce by a police officer in uniform authorized by the state government.
• These issue certificates if a vehicle is found complying with the prescribed emission norms.
• Since the Motor Vehicles (Amendment) Act, 2019 came into force, PUC certificate has been made mandatory.
• A PUC certificate contains information such as the vehicle’s license plate number, PUC test reading, date on which the PUC test was conducted and the expiry date.

Compliance rules

• According to Central Motor Vehicles Rules, 1989, every motor vehicle is required to carry a valid PUC Certificate after the expiry of period of one year from the date of its first registration.
• This includes those conforming to BS-I/ BS-II/ BS-III/BS-IV /BS-VI as well as vehicles plying on CNG/LPG.
• However, the validity of four-wheeled BS-IV compliant vehicles is one year and for other vehicles it is three months.

How is a pollution control check carried out?

• The computerized model for pollution check was developed by the Society of Indian Automobile manufacturers.
• A gas analyzer is connected to a computer, to which a camera and a printer are attached.
• The gas analyzer records the emission value and sends it to the computer directly, while the camera captures the license plate of the vehicle.
• Subsequently, a certificate may be issued if the emission values are within the limits.

Why obtain PUC Certificate?

• Emissions from automobiles are major contributors to air pollution all over the world.
• The smoke emitted from vehicles contains the following pollutants:

1. Hydrocarbons (HC)
2. Carbon Monoxide (CO)
3. Oxides of Nitrogen (NO_x)
4. Particulate Matter (PM)
5. Sulphur Dioxide (SO₂)
6. Carbon Dioxide (CO₂)
7. Nitrous Oxide (N₂O)

We often get confused to differentiate between Cheetah/Bagh/Sher/Puli. The cheetah, which is being re-introduced to India from Africa, is not to be confused with the leopard, which too has spots that look somewhat similar.

How are all Big Cats differentiated?

[A] Genus Panthera

• This is the genus of large wild cats that can roar but can’t purr.
• Among them, the lion, the leopard, and the jaguar are more closely related, while the other strand has the tiger and the snow leopard.
• The snow leopard is an exception to the rest of the group in that it can’t roar.

(1) Tiger (Panthera Tigris)

Size: 75-300 kg | IUCN status : Endangered

• Jim Corbett’s “large-hearted gentleman with boundless courage”, the solitary and strongly territorial tiger is the largest of all wild cats and also the earliest Panthera member to exist.
• Primarily a forest animal, they range from the Siberian taiga to the Sunderban delta.
• The national animal of India, Bangladesh, Malaysia, and South Korea, the tiger was voted the world’s favourite animal ahead of the dog in a 2004 Animal Planet global online poll.

(2) Lion (Panthera Leo

Size: 100-250 kg | IUCN status: Vulnerable

• Native to Africa and Asia, the lion is the most social cat, and lives in groups called prides.
• They prefer open forests such as scrubland, and adult males have a prominent mane.
• The lion is arguably the most widely recognised animal symbol in human culture — be it the Ashoka pillar in Sarnath, the main entrance to Buckingham Palace, or the 20th Century Fox and MGM logo.

(3) Jaguar (Panthera Onca)

Size: 50-110 kg | IUCN status: Near Threatened

• The largest cat in the Americas, the Jaguar has the strongest bite force of all wild cats, enabling it to bite directly through the skull of its prey.
• Melanistic (black) Jaguars are common and are often called black panthers.
• Jaguar was a powerful motif in the Mayan and Aztec civilisations.

(4) Leopard (Panthera Pardus)

Size: 30-90 kg | IUCN status: Vulnerable

• Similar in appearance to the Jaguar with a rosette patterned coat, the leopard was described by Jim Corbett as “the most beautiful of all animals” for its “grace of movement and beauty of colouring”.
• The most adaptable of all big cats, they occupy diverse habitats at all altitudes across Africa and Asia.
• Like black jaguars, melanistic leopards are called black panthers.
• In some African cultures, leopards are considered to be better hunters than lions.

(5) Snow leopard (Panthera Uncia)

Size: 25-55 kg | IUCN status : Vulnerable

• The ghost of the mountains, this smokey-grey cat lives above the snow line in Central and South Asia.
• The most elusive of all big cats, it cannot roar, and has the longest tail of them all — which comes in handy for balance while hunting along the cliffs, and also gives warmth when wrapped around the body.
• The snow leopard is the state animal of Ladakh and Himachal Pradesh.

[B] Genus Puma

• Closely related to the domestic cat, this genus has only one extant species, the cougar.

Cougar (Puma concolor)

Size: 40-100 kg | IUCN status: Least Concern

• The cougar is the second-largest cat in the Americas. (The Jaguar is the largest.)
• Cougars are also called ‘mountain lion’ and ‘panther’ across their range from the Canadian Yukon to the Southern Andes.
• Concolor is latin for “of uniform colour”. The Incas designed the city of Cusco in the shape of a cougar.

[C] Genus Acinonyx

• This is a unique genus within the cat family, with only one living member, the cheetah.

Cheetah (Acinonyx jubatus)

Size: 20-70 kg | IUCN status: Vulnerable

• The fastest land mammal, the cheetah is the only cat without retractable claws — the grip helps it accelerate faster than any sports car (0-100 km/hr in 3 seconds).
• Cheetahs are not aggressive towards humans, and they have been tamed since the Sumerian era.
• They don’t breed well in captivity — picky females play hard to get.
• Cheetahs are not really big, and they hunt during the day to avoid competing with other big cats.

Since July 1, 2022, India has banned the manufacture, import, stocking, distribution, sale, and use of single-use plastics (SUP) items with low utility and high littering potential.

What are single-use plastics?

• Single-use plastics, often also referred to as disposable plastics, are commonly used for plastic packaging and include items intended to be used only once before they are thrown away or recycled.
• These include, among other items, grocery bags, food packaging, bottles, straws, containers, cups and cutlery.

Why are single-use plastics harmful?

• The purpose of single-use plastics is to use them once or for a short period of time before disposing of them. Plastic waste has drastic impacts on the environment and human health.
• There is a greater likelihood of single-use plastic products ending up in the sea than reusable ones.

SUP ban in India

• India has taken resolute steps to mitigate pollution caused by littered single-use plastics.
• A number of items are banned, including earbuds with plastic sticks, balloon sticks, plastic flags, candy sticks, ice cream sticks, polystyrene (thermocol) for decorations, plates, cups, glasses, cutlery such as forks, spoons, knives, straws etc.
• India has also banned plastic or PVC banners less than 100 micron, stirrers, etc.

What is the impact on the environment?

[A] Solid Waste generation

• The disposal of plastics is one of the least recognized and most highly problematic areas of plastic’s ecological impact.
• Ironically, one of plastic’s most desirable traits: its durability and resistance to decomposition, is also the source of one of its greatest liabilities when it comes to the disposal of plastics.
• A very small amount of total plastic production (less than 10%) is effectively recycled; the remaining plastic is sent to landfills.
• It is destined to remain entombed.

[B] Ecological Impact

(i) Groundwater and soil pollution

• Plastic is a material made to last forever, and due to the same chemical composition, plastic cannot biodegrade; it breaks down into smaller and smaller pieces.
• When buried in a landfill, plastic lies untreated for years.
• In the process, toxic chemicals from plastics drain out and seep into groundwater, flowing downstream into lakes and rivers.
• The seeping of plastic also causes soil pollution and have now started resulting in presence of micro plastics in soil.

(ii) Water Pollution

• The increased presence of plastic on the ocean surface has resulted in more serious problems.
• Since most of the plastic debris that reaches the ocean remains floating for years as it does not decompose quickly, it leads to the dropping of oxygen level in the water.
• It has severely affected the survival of marine species.
• When oceanic creatures and even birds consume plastic inadvertently, they choke on it which causes a steady decline in their population.
• In addition to suffocation, ingestion, and other macro-particulate causes of death in larger birds, fish, and mammals.

[C] Health Hazards

• Burning of plastic results into formation of a class of flame retardants called as Halogens.
• Collectively, these harmful chemicals are known to cause the following severe health problems: cancer, neurological damage, endocrine disruption, birth defects and child developmental disorders etc.

Ban elsewhere

• India is not the first country to ban single-use plastics.
• Bangladesh became the first country to ban thin plastic bags in 2002; New Zealand banned plastic bags in July 2019.
• China had issued a ban on plastic bags in 2020 with a phased implementation.
• As of July 2019, 68 countries have plastic bag bans with varying degrees of enforcement.

What are the plastic waste management rules in India?

• With effect from September 30, 2021 India has the Plastic Waste Management Amendment Rules, 2021.
• It prohibited the manufacture, import, stocking, distribution, sale, and use of plastic carry bags whose thickness is less than 75 microns.
• From December 31, 2022, plastic carry bags whose thickness is less than 120 microns will be banned.
• It means that the ban does not cover all plastic bags; however, it requires the manufacturers to produce plastic bags thicker than 75 microns which was earlier 50 microns.
• As per the notification, the standard shall be increased to 120 microns in December this year.

What is the role of the manufacturer?

• In addition, the Ministry of Environment, Forests, and Climate Change notified the Plastic Waste Management Amendment Rules, 2022 on February 16, 2022.
• Extended Producer Responsibility (EPR) is the responsibility of a producer for the environmentally sound management of the product until the end of its life.
• The guidelines provide a framework to strengthen the circular economy of plastic packaging waste, promote the development of new alternatives to plastic packaging and provide the next steps for moving towards sustainable plastic packaging by businesses.

Various steps taken

• The Indian government has taken steps to promote innovation and create an ecosystem for accelerated adoption and availability of alternatives across the country.
• To ensure the effective enforcement of the ban, national and State-level control rooms will be established, as well as special enforcement teams for the purpose of checking the illegal sale and use of single-use plastics.
• To prevent the movement of banned single-use plastic items between States and Union Territories, border checkpoints have been established.
• In an effort to empower citizens to help curb the plastic menace, the Central Pollution Control Board (CPCB) has launched a grievance redressal application.

What are the challenges?

• The ban will succeed only if all stakeholders participate enthusiastically and engage in effective engagement and concerted actions.
• However, if we look back at our past, almost 25 Indian States previously banned plastic at the state level.
• However, these bans had a very limited impact in reality because of the widespread use of these items.
• Now the challenge is to see how the local level authorities will enforce the ban in accordance with the guidelines.
• Banned items such as earbuds with plastic sticks, plastic sticks for balloons, etc., are non-branded items and it is difficult to find out who the manufacturer is and who is accountable.

Way forward

• The consumer needs to be informed about the ban through advertisements, newspaper or TV commercials, or on social media.
• In order to find sustainable alternatives, companies need to invest in research and development.
• The solution to the plastic pollution problem is not the responsibility of the government alone, but of industries, brands, manufacturers and most importantly consumers.
• Finding alternatives to plastic seems a little difficult, however, greener alternatives to plastic may be considered a sustainable option.
• For example, compostable and bio-degradable plastic, etc., may be considered as an option.
• While the total ban on the use of plastic sounds a great idea, its feasibility seems difficult at this hour, especially in the absence of workable alternatives.
