  • Misuse of EPR legislation worsening India’s plastic problem, shows CSE report

    Why in the News?

    The Indian government’s 2022 “Extended Producer Responsibility” guidelines mark progress, but a recent report states that stronger measures are needed to fully enforce the “polluter pays” principle in plastic waste management, per a recent CSE report.

    What is the CSE report? 

    • A CSE report is a publication by the Centre for Science and Environment (CSE), a prominent Delhi-based think tank focused on environmental research and advocacy.
    • CSE reports analyze pressing environmental issues, often providing data-driven insights and policy recommendations.

    What is Extended Producer Responsibility (EPR)? 

    • Extended Producer Responsibility (EPR) is a policy approach where producers are given significant financial and sometimes operational responsibility for the treatment or disposal of post-consumer products.
    • The primary goal of EPR is to make manufacturers accountable for the entire lifecycle of their products, especially in terms of environmental impact, by ensuring that they take part in the collection, recycling, and disposal processes.

    Extent of the misuse of EPR certificates in India’s plastic recycling industry

    • Fake Certificates: An assessment by the Centre for Science and Environment (CSE) and findings from the Central Pollution Control Board (CPCB) revealed the generation of over 700,000 fake recycling certificates, indicating widespread fraud among plastic recyclers.
    • Certificate Inflation: Some processors and recyclers reported volumes vastly exceeding their registered capacities.
      • For example, cement plants engaged in end-of-life co-processing claimed to process 335.4 million tonnes annually, despite an actual capacity of only 11.4 million tonnes.
    • Undermined Trust: Fraudulent activities result in artificially low certificate prices, undermining the credibility of the EPR system and making it difficult to accurately track plastic waste management.

    How does this impact environmental compliance and plastic waste management?

    • Underreported Waste Generation: PIBOs introduced 23.9 million tonnes of plastic packaging in April 2022, translating to an annual waste generation of approximately 8 million tonnes. However, CPCB’s estimate of 4.1 million tonnes of plastic waste generation annually indicates significant underreporting.
    • Limited Stakeholder Participation: The absence of key contributors, such as urban local bodies and informal waste collectors from the EPR system, reduces traceability and leaves much of the waste management burden on local governments.
    • Compromised Recycling Integrity: Due to low-cost fraudulent certificates, genuine recycling efforts suffer from underfunding and inadequate regulation, jeopardizing sustainable plastic waste management efforts and hindering the implementation of the “polluter pays” principle.

    What measures can be implemented to improve oversight and accountability within the EPR framework?

    • Inclusion of Informal Sector: Recognizing and formalizing the role of informal waste collectors and urban local bodies within the EPR framework could enhance waste collection, segregation, and recycling rates, creating a more transparent value chain.
    • Combatting Fraud: Strengthening the auditing and certification process to identify and remove fraudulent recyclers and processors, supported by stricter legal and financial penalties, would help deter misuse.
    • Transparent Reporting: Enhancing the EPR portal to ensure accurate data collection on plastic waste generation and disposal, and setting fair prices for recycling certificates to prevent undervaluation.
    • Standardizing Products: By mandating uniform standards for plastic packaging materials and designs, recyclability could be improved, reducing contamination and making recycling more effective.
    • Enhanced Monitoring and Accountability: Strengthening CPCB and State Pollution Control Boards’ (SPCBs) monitoring capacity and ensuring consistent enforcement of guidelines at both the state and central levels.

  • What is the Hasdeo Arand Forest?

    Why in the News?

    In Chhattisgarh’s Hasdeo Arand forest, tribals ambushed the police after tree-felling resumed for coal mining in the area.

    What is the Hasdeo Arand Forest?

    • Hasdeo Arand Forest is known as the “lungs of Chhattisgarh” due to its rich biodiversity.
    • It is the largest unfragmented forest in Central India with pristine Sal and teak forests.
    • It spans 1,879.6 sq km across the Sarguja, Korba, and Surajpur districts in Chhattisgarh.
      • The Hasdeo River runs through the forest.

  • Why ‘protected’ areas are seeing faster biodiversity decline?

    Why in the News?

    According to a recent study conducted by the Natural History Museum (NHM) in London, biodiversity is decreasing more rapidly within key protected areas than outside of them.

    What did the Biodiversity Intactness Index (BII) say?

    • The Biodiversity Intactness Index (BII) is a quantitative measure designed to assess the state of terrestrial biodiversity with its natural baseline, before significant human impact.
    • It decreased by 1.88% points globally between 2000 and 2020, indicating a loss in the average natural biodiversity of regions worldwide.
    • Within the 22% of ‘Critical Biodiversity Areas’ that are protected, biodiversity has declined by 2.1 percentage points, while non-protected areas saw a decline of 1.9 percentage points during the same period.

    Why is the decline happening?

    • Inadequate Ecosystem Protection: Many protected areas focus only on specific species rather than the entire ecosystem, failing to prioritize overall biodiversity intactness.
    • Pre-existing Degradation: Some protected areas may have been already degraded before being designated as protected, limiting their effectiveness in conserving biodiversity.
    • External Threats: Activities such as oil, gas, and mining concessions encroach on protected areas, leading to habitat destruction and further biodiversity loss.
    • Climate Crisis Impact: Increased frequency of extreme weather events, such as droughts and wildfires, has severely affected protected areas, undermining their conservation efforts.

    Steps taken by the Indian Government to conserve biodiversity:

    • Legislative Framework

        • Biological Diversity Act, 2002: Established to conserve biological resources and regulate access to these resources, ensuring equitable sharing of benefits derived from their use.
        • Wild Life (Protection) Act, 1972: Facilitates the creation of Protected Areas for wildlife conservation and imposes penalties for illegal hunting.

    • Conservation Policies:

        • Project Tiger: Launched in 1973, this initiative aims to protect tiger populations across designated reserves.
        • Project Elephant: Initiated in 1992, it focuses on the management and protection of wild elephant populations and their habitats.
        • National Biodiversity Mission: A mission mode initiative aimed at documenting and conserving India’s biodiversity.

    • Protected Areas

      • Establishment of a Protected Area Network: This includes National Parks, Wildlife Sanctuaries, Conservation Reserves, and Community Reserves to provide better protection for wildlife and their habitats.
      • Designation of Biosphere Reserves: These reserves are aimed at conserving representative ecosystems.

    What should be done? (Way forward)

    • Ecosystem-Centric Management: Shift focus from individual species to the overall health of ecosystems to ensuring comprehensive protection of habitats and their interdependent species.
    • Strengthened Protection and Regulation: Implement stricter regulations to limit industrial activities (e.g., oil and gas exploration) within and around protected areas, alongside enforcing more robust land-use policies.
    • Community Engagement and Education: Involve local communities in conservation efforts and enhance public awareness about biodiversity’s importance, fostering a collective responsibility for sustainable practices.

  • US court to decide whether elephants get human rights

    Why in the News?

    Colorado’s highest court recently reviewed whether older African female elephants can legally contest their captivity, as the NonHuman Rights Project claims they are unlawfully confined.

    What is nonhuman?

    • Nonhuman animals are living beings other than humans, including mammals, birds, reptiles, fish, and insects, recognized for their capacity to feel, behave, and interact.

    What is Legal personhood? 

    • Legal personhood is the status granted to an entity, allowing it to hold legal rights and obligations, traditionally applied to humans and some organizations.
    • Example: All human individuals are recognized as legal persons. This allows them to enter into contracts, sue, and be sued in court.

    What Constitutes Legal Personhood for Nonhuman Animals?

    • Legal Personhood Definition: Legal personhood refers to the capacity of an entity to have legal rights and duties. In law, a “person” is not strictly limited to human beings; corporations, for example, are considered legal persons.
    • Application to Nonhuman Animals: Extending legal personhood to nonhuman animals involves granting them certain legal rights, such as the right to not be unlawfully confined or exploited. This would require redefining animals’ status from property to beings with inherent rights.
    • Arguments in Favor: Proponents argue that certain highly intelligent and socially complex animals, such as elephants, dolphins, and great apes, should be granted legal rights because they can experience suffering and possess a degree of autonomy akin to that of humans.
    • Arguments Against: Opponents of legal personhood for animals argue that the legal system is designed for human society and extending personhood to animals could lead to complex legal issues.
      • They contend that animal welfare can be ensured through legislative protections rather than redefining personhood.

    How can societies balance animal welfare with cultural practices that might clash with today’s views on animal rights?

    • Engagement and Dialogue: Encourage conversations between cultural leaders, communities, and animal rights advocates to understand different perspectives and find common ground on how to improve animal welfare while respecting traditions.
    • Education and Awareness: Promote education about animal welfare and the capacity of animals to feel pain and suffering, helping communities to reconsider practices and adopt alternatives that align with both cultural values and humane treatment.
    • Legal Frameworks: Implement laws that protect animal welfare while allowing for cultural practices to continue in a regulated manner, ensuring that such practices do not involve cruelty or inhumane treatment of animals.

    What are the Rights of Animals in the Indian Context?

    • Traditional and Cultural Practices: In India, animals play a significant role in various cultural and religious practices. For instance, cows are considered sacred in Hinduism, while elephants are used in festivals and ceremonies.
    • Legal Framework for Animal Rights: India has several laws aimed at protecting animal rights, such as the Prevention of Cruelty to Animals Act, 1960, and the Wildlife Protection Act, 1972. These laws establish standards for animal welfare and criminalize cruelty.
      • However, they stop short of granting legal personhood to animals.
    • Judicial Intervention: The Indian judiciary has taken progressive stances on animal rights in some cases.
      • For example, the Uttarakhand High Court in 2018 declared all animals in the state to be legal entities, with citizens acting as guardians. This ruling emphasized the need to protect animals’ dignity and well-being, though it did not grant full legal personhood.

    Conclusion: India can look toward a framework that balances animal welfare with cultural practices by adopting context-specific policies. This could include creating more robust welfare standards, engaging with communities to find humane alternatives, and fostering a cultural shift toward greater empathy for animals.

  • Lahore: The World’s most Polluted City

    Why in the News?

    • Lahore was declared the world’s most polluted city by air quality monitor IQAir, with an Air Quality Index (AQI) of 394, considered hazardous by global standards.
      • Delhi ranks 2nd, recording an AQI of 204, also classified as “very unhealthy.”
      • Lahore’s AQI value exceeds the World Health Organisation (WHO) guideline by over 55.6 times.

    Primary Causes of Lahore’s Severe Air Pollution:

    • Stubble Burning: Farmers in Punjab (India and Pakistan) burn crop residue, especially after rice harvesting, during winter to prepare fields for wheat cultivation.
    • Vehicular Emissions: The rise in the number of vehicles in Lahore, along with the use of low-quality fuel, results in high levels of PM2.5 emissions, a major contributor to air pollution.
    • Industrial Pollution: Factories and brick kilns in and around Lahore emit harmful pollutants, including particulate matter, adding to the city’s poor air quality.
    • Geography and Weather Conditions: Lahore’s location in a low-lying region and its geography, surrounded by hills, leads to temperature inversion during the winter, trapping pollutants near the surface and preventing their natural dispersal.
    • Coal-Fired Power Plants: Large power plants, such as the 1320MW Sahiwal coal-fired power plant in Punjab, part of the China-Pakistan Economic Corridor (CPEC), emit sulphur and other pollutants, significantly contributing to smog and air pollution.

    Who Ranks the Most Polluted Cities of the World and How?

    • IQAir, a Swiss air quality monitoring company, ranks the most polluted cities based on real-time air quality data.
    • The rankings focus on the concentration of PM2.5 particles, which are small enough to penetrate the lungs and pose serious health risks.
    • Cities are ranked using the AQI scale (0-500), with AQI above 300 indicating hazardous pollution levels.
    • IQAir uses data from government agencies, monitoring stations, and low-cost sensors across various regions.
    • Real-time monitoring allows IQAir to provide up-to-date information about air pollution levels in cities around the world.
    • The data is compared with WHO standards, which recommend PM2.5 levels below 5 micrograms per cubic meter for healthy air quality.
