Quick Revision: NHAI’s revised tree plantation norms mandate 80% coverage and 90% survival rate of saplings along national highways before issuance of Provisional Completion Certificate, integrating environmental sustainability into highway project compliance frameworks.

Why is this in the news?

On 9 September 2026, the National Highways Authority of India (NHAI) issued revised guidelines to enforce stricter compliance with tree plantation norms before the issuance of Provisional Completion Certificates (PCC) for national highway projects. These guidelines mandate a minimum of 80% plantation coverage and a 90% survival rate of planted saplings along highway corridors, integrating environmental sustainability into the core operational and maintenance frameworks of highway projects.

Background

• The National Highways Authority of India (NHAI) is the apex body responsible for the development, maintenance, and management of National Highways in India under the Ministry of Road Transport and Highways.
• Tree plantation along national highways has been a contractual obligation under various project agreements, including Build-Operate-Transfer (BOT), Engineering Procurement and Construction (EPC), and Hybrid Annuity Model (HAM) projects.
• The Green Highways Policy, 2015, was introduced to promote greening of highway corridors and to ensure environmental sustainability in highway development.
• The Indian Roads Congress (IRC) standard IRC:SP:21-2009 provides guidelines for roadside plantation and landscaping in highway projects.
• Prior to the revised guidelines, compliance with tree plantation norms was often inadequately enforced, leading to suboptimal environmental outcomes despite contractual obligations.

What are the Revised Tree Plantation Norms for National Highways?

• NHAI has introduced stringent compliance criteria for tree plantation along national highways, applicable to all project modes including EPC, HAM, and BOT.
• A minimum of 80% of the designated Right of Way (RoW) must be covered with plantation, ensuring a continuous green corridor along highways.
• The survival rate of planted saplings must be at least 90% at the time of inspection for the issuance of the Provisional Completion Certificate (PCC) or Provisional Commercial Operation Date (PCOD).
• Non-compliance with the 80% plantation coverage will trigger financial deductions in payments under the contract until full compliance is achieved.
• For projects under the Operations and Maintenance (O&M) phase, a minimum 90% survival rate of planted saplings must be maintained to release O&M or annuity payments.
• The guidelines mandate the replacement of dead or damaged saplings with plants of similar age and growth potential to maintain uniformity and continuity of the green corridor.
• NHAI will engage environmental and plantation experts to verify compliance at the field level before certifying maintenance payments or compliance status.
• The revised norms integrate environmental sustainability into the project lifecycle, from construction to long-term maintenance, ensuring alignment with the Green Highways Policy, 2015, and IRC:SP:21-2009 standards.

Key Features

Feature	Significance
Mandatory 80% plantation coverage on ROW	Ensures uniform green cover along national highways, enhancing ecological balance and aesthetic continuity.
90% plant survival rate threshold	Guarantees sustainability of afforestation efforts, preventing short-term failures in environmental compliance.
Financial deductions for non-compliance	Incentivises contractors to adhere to environmental obligations through monetary penalties for incomplete or failed plantations.
Integration with PCC/PCOO issuance	Links environmental compliance directly to project completion certification, reinforcing accountability in infrastructure delivery.
O&M phase survival rate (90%)	Maintains ecological integrity during the operational phase, ensuring long-term environmental benefits of highway projects.
Expert verification for compliance	Utilises technical oversight to validate plantation standards, reducing subjective errors in assessment.

Why it Matters

Environmental Governance

• Elevates environmental sustainability from a peripheral activity to a core contractual obligation in highway projects.
• Aligns with India’s commitments under international environmental agreements (e.g., Paris Agreement) and national policies like the Green Highways Policy, 2015.
• Promotes biodiversity conservation by mandating structured afforestation along linear infrastructure corridors.

Institutional Accountability

• Strengthens the role of NHAI as a regulator-cum-implementer in environmental governance of infrastructure projects.
• Introduces third-party verification (environmental experts) to ensure objective compliance assessment.
• Establishes a precedent for integrating environmental safeguards into project lifecycle management.

Economic Efficiency

• Reduces long-term costs associated with compensatory afforestation or penalties for non-compliance.
• Enhances asset value by improving the ecological and aesthetic appeal of national highways.
• Optimises resource allocation by linking financial disbursements to measurable environmental outcomes.

Policy Integration

• Bridges gaps between construction-phase obligations and operational-phase maintenance, ensuring continuity in environmental compliance.
• Harmonises with existing guidelines (IRC:SP:21-2009, MoRTH directives) to create a cohesive regulatory framework.

Challenges

1. Contractor Compliance Gaps

• Historical under-prioritisation of afforestation obligations in highway contracts may lead to resistance or delayed adherence.
• Variability in regional climatic conditions could affect plant survival rates, necessitating adaptive strategies.

Challenges — UPSC Perspective

Issue	Concern
Climatic Variability	Adverse weather conditions (droughts, floods) may reduce plant survival rates despite contractor efforts.
Contractor Incentives	Short-term profit motives may discourage investment in long-term environmental compliance.
Species Selection	Inappropriate species for local conditions may lead to high mortality rates.
Monitoring Infrastructure	Inadequate field-level monitoring tools (e.g., remote sensing, drones) for large-scale verification.
Legal Enforcement	Delays in penalising non-compliance due to contractual ambiguities or appeals processes.

Way Forward

• Conduct regional workshops to sensitise contractors and state agencies on revised afforestation guidelines and survival rate targets.
• Develop a digital dashboard for real-time tracking of plantation coverage and survival rates across NHAI projects.
• Establish a dedicated fund for procurement of high-survival-rate saplings and post-plantation maintenance.
• Collaborate with agricultural universities and forestry institutes to identify region-specific species for optimal survival.
• Introduce performance-based incentives (e.g., bonus payments) for contractors exceeding survival rate thresholds.
• Strengthen inter-agency coordination through joint monitoring committees involving NHAI, MoRTH, and state forest departments.
• Publish quarterly compliance reports to enhance transparency and public accountability in environmental governance.
