SUBJECT CODE 89 • PAPER 2

UGC NET Environmental Science Syllabus 2026

Your complete guide to all 10 units, unit-wise weightage, exam pattern, high-yield topics and the best books to crack Paper 2 for Assistant Professor & JRF.

The UGC NET Environmental Science syllabus is issued by the National Testing Agency (NTA) for candidates aiming to qualify as Assistant Professors or for the Junior Research Fellowship (JRF). It is a strongly interdisciplinary subject, blending ecology, chemistry, geosciences, energy, pollution control, waste management, law, statistics and contemporary environmental issues across ten units. This guide breaks down every unit, shows the likely question-load per unit, and points you to the right books so your preparation stays focused on what actually gets tested.

Smart Preparation Strategy

Anchor your preparation in the three heaviest units — Environmental Pollution & Control, Environmental Biology and Environmental Assessment/Legislation — because together they contribute the largest share of Paper 2. Build conceptual clarity in ecology, chemistry and geosciences, then layer on energy, waste management and statistics. Because recent papers are increasingly application-based, stay updated on current environmental issues such as climate change, SDGs, EIA cases and carbon credits. Keep concise notes on laws, conventions and key definitions, and solve 8–10 years of previous papers with regular mock tests to master the 100-question Paper 2.
