NITI Aayog Releases Net Zero Roadmap for Waste Sector

What's the News?

• NITI Aayog released Volume 8 of its landmark study "Scenarios Towards Viksit Bharat and Net Zero", presenting a strategic roadmap for transforming India's waste sector into a resource recovery powerhouse.
• The report outlines pathways to align India's Viksit Bharat 2047 vision with its Net Zero 2070 climate commitment, focusing on decoupling economic growth from greenhouse gas (GHG) emissions in waste management.
• It projects that without intervention, waste sector emissions could grow 3.5 times by 2070, but with aggressive action, emissions can be reduced by 95.9% compared to current policy trajectories.

Waste Sector Emissions Challenge

• Current Footprint: The waste sector contributed approximately 76 MtCO2e in 2020, representing 2.56% of India's total GHG emissions and ranking as the fourth-largest emission source.
• Growth Trajectory:
  • Municipal Solid Waste (MSW): Daily generation of 170,000 tonnes (62 million tonnes annually) projected to reach 165 million tonnes by 2030 and 436 million tonnes by 2050.
  • Wastewater: 221,173 million litres per day generated domestically, with only 44.9% currently treated.
• Emission Composition:
  • Methane (CH4) dominates at 75.7% of waste sector emissions (from landfills and wastewater).
  • Domestic wastewater accounts for 45% of sub-sector emissions, industrial wastewater for 29%, and solid waste management for 26%.

Two Scenarios: Current Policy vs. Net Zero

Strategic Interventions

• Universal Collection: Achieve 100% door-to-door solid waste collection and complete wastewater treatment by 2047.
• Source Segregation: Mandate strict segregation into biodegradable, recyclable, and non-recyclable categories to enable resource recovery.
• Bio-methanation Scale-up: Process wet waste through bio-methanation and bio-CNG production; processing just 50% of wet waste could generate ₹2,460 crore annually.
• Circular Economy Integration:
  • Formalize the informal waste sector (currently handling 90% of e-waste through unauthorized channels).
  • Strengthen Extended Producer Responsibility (EPR) frameworks for batteries, e-waste, and plastics.
• Technology Deployment: Deploy anaerobic digestion systems with methane capture for wastewater treatment to replace aerobic systems that release emissions.

Constitutional & Policy Framework:

• Solid Waste Management Rules, 2016: Mandate source segregation and scientific disposal; extended to villages with population >3,000 in 2020 amendment.
• Plastic Waste Management Rules, 2016: Established EPR framework for plastic producers, importers, and brand owners.
• National Policy on Faecal Sludge and Septage Management, 2017: Addresses safe management of human waste from onsite sanitation systems.

Flagship Missions:

• Swachh Bharat Mission (Urban 2.0): Already bio-remediated 1,140 lakh tonnes of legacy waste from 2,429 dump sites (48% of total legacy waste).
• AMRUT 2.0: Focuses on universal water supply and sewerage coverage in all statutory towns.
• GOBARdhan (Galvanizing Organic Bio-Agro Resources Dhan): Promotes bio-CNG production from agricultural and organic waste.
• SATAT (Sustainable Alternative Towards Affordable Transportation): Initiative to establish compressed biogas plants.

Defence Ministry Frames Fresh Guidelines for Military Publications

What's the News?

• The Ministry of Defence (MoD) is formulating comprehensive publication guidelines for serving and retired armed forces personnel following controversy over former Army Chief General M.M. Naravane's unpublished memoir "Four Stars of Destiny".
• The proposed framework aims to standardize the clearance process for manuscripts and incorporate provisions of the Official Secrets Act, 1923, which continues to bind personnel even after retirement.
• The move addresses current regulatory gaps, as India lacks a single unified law governing book publications by former military officers.

The Naravane Memoir Controversy

• Unpublished Content Cited: Leader of Opposition Rahul Gandhi quoted excerpts from the memoir in Lok Sabha regarding the 2020 India-China border standoff, triggering government protests that the book lacked defence establishment clearance.
• Speaker's Intervention: The Lok Sabha Speaker barred further references to the text, terming it "unauthenticated unpublished content".
• Legal Action: Delhi Police registered an FIR over alleged unauthorized circulation of a preprint version, investigating how manuscript portions entered the public domain.
• Publisher's Clarification: Penguin Random House India (sole publishing rights holder) and General Naravane confirmed no copies have been published in any format, and any circulating version constitutes copyright infringement.

Proposed Guidelines Framework

• Scope: Covers both serving and retired personnel across Army, Navy, and Air Force.
• Clearance Process: Will spell out mandatory submission and verification procedures before publication approval.
• Legal Foundation: Builds upon:
  • Official Secrets Act, 1923 provisions (lifelong applicability).
  • Defence Service Regulations for serving personnel.
  • Army Act provisions where applicable.
• Objective: Close procedural gaps and prevent unauthorized disclosure of sensitive operational information, classified material, and intelligence inputs.

Current Regulatory Landscape

For Serving Personnel

• Mandatory Prior Permission: Defence Service Regulations require written clearance before undertaking any literary, political, or remunerative activity outside official duties.
• Prohibited Content: Classified information, operational details, internal procedures, equipment capabilities, intelligence inputs, and matters affecting national security or foreign relations.
• Approval Chain: Requests routed through command structure up to Army Headquarters or MoD depending on content sensitivity.

For Retired Personnel

• No Specific Service Rules: Retired officers fall outside Army Act jurisdiction on publication matters.
• Official Secrets Act Applies: Lifelong criminal liability for disclosing classified or operationally sensitive material.
• Expected Protocol: Voluntary submission of manuscripts containing sensitive content to MoD for verification and clearance.
• Self-Regulation: Relies largely on individual maturity and judgment regarding what constitutes classified vs. public domain information.

Official Secrets Act, 1923

• Colonial-Era Legislation: Enacted April 2, 1923, to consolidate laws protecting official information and prevent espionage.
• Applicability: Covers all persons including government servants, defence personnel, private individuals, and companies; extends to Indian citizens outside India.
• Spying (Section 3): Punishes approaching prohibited places, making sketches, or collecting information useful to enemies; imprisonment up to 14 years for defence-related offences, 3 years for other cases.
• Wrongful Communication (Section 5): Criminalizes unauthorized sharing, retention, or misuse of official codes, documents, or information affecting sovereignty, integrity, security, or friendly relations with foreign states.
• Special Rule of Evidence: For military offences, conviction possible based on circumstances, conduct, or known character without proving specific prejudicial acts.
• Trial Restrictions (Section 13): Courts can take cognizance only upon complaint authorized by appropriate Government.
• Closed Proceedings (Section 14): Courts may exclude public during trial if evidence publication may prejudice State security.
