GATE Environmental Science and Engineering (ES) is a specialized branch in the Graduate Aptitude Test in Engineering, introduced in 2021 to address the growing need for environmental protection, sustainable development, and pollution control. This branch tests your understanding of environmental chemistry, air and water pollution, waste management, environmental impact assessment, and sustainable engineering practices. Practicing GATE ES previous question papers is crucial for understanding the exam format and improving your performance.
Environmental Science and Engineering combines principles from chemistry, biology, civil engineering, and chemical engineering to develop solutions for environmental challenges. GATE ES aspirants typically include graduates from Environmental Engineering, Civil Engineering, Chemical Engineering, Chemistry, and related backgrounds who wish to pursue higher studies or careers in environmental consulting firms, pollution control boards, research organizations, government agencies like CPCB, SPCB, and industries focused on sustainability and environmental compliance. The field encompasses areas such as water and wastewater treatment, air pollution control, solid waste management, environmental monitoring, climate change mitigation, and environmental policy.
