New Delhi, Nov. 11 -- Diwali is over. Firecracker sellers have made their profits, and we have done what we seem to do best: pollute our cities. The observation may sound somewhat mawkish, but the data paints a grim picture. As many as 49 of the world's 50 most polluted cities are in India. A global city pollution ranking released on Tuesday placed Rajasthan's Sri Ganganagar at the top, with an Air Quality Index (AQI) of 821. Cities in Punjab, Haryana, Rajasthan and Uttar Pradesh dominated the rankings, while Delhi stood at the 24th position. The only city outside India to feature on the list was Pakistan's Lahore, which ranked 14th with an AQI of 430.
Against the backdrop of worsening air quality and the growing impact of climate change, the demand for specialised education in sustainability and climate studies is gaining momentum in India. Several universities and online learning platforms are now offering programmes that equip students and professionals with the knowledge and skills needed to understand climate challenges and develop sustainable solutions.
Globally, some of the most reputed institutions for climate and environmental studies include Harvard University, which ranks among the world's best for Environmental Sciences in the QS World University Rankings. The University of Oxford holds the second position in the subject and offers specialised programmes such as the MSc in Environmental Change. It is also home to the Smith School of Enterprise and the Environment. Stanford University in the US has the Stanford Doerr School of Sustainability, along with interdisciplinary master's programmes in Earth Systems and climate innovation. Yale University, meanwhile, offers specialised academic opportunities through its School of the Environment, with a focus on policy, conservation and global climate governance.
In India, the Indira Gandhi National Open University (IGNOU) offers a two-year, English-language MSc in Climate Change. The specialised programme aims to provide students with a comprehensive understanding of climate science, climate-related risks and sustainable solutions for building resilient societies and ecosystems. Its multidisciplinary curriculum examines the relationship between climate change and critical sectors such as water resources, energy systems, agriculture, disaster risk reduction, waste management and the circular economy. It also brings together scientific, environmental, social, legal, governance and policy perspectives to offer a holistic understanding of the subject.
Azim Premji University, too, offers postgraduate learning opportunities in climate change through its MA in Development programme at the Bengaluru campus. The programme covers three important dimensions of the subject: climate science, climate mitigation and climate adaptation.
Harvard University also offers several online learning opportunities in the field. Its five-week Business and Climate Change programme, offered through Harvard Business School (HBS) Online, explores the science of climate change, its economic implications and the associated policy challenges. Another seven-week online programme, Climate Leadership: Creating Change in Uncertain Times, is scheduled to begin in January 2027. It focuses on developing climate leadership, navigating the complexities of collective decision-making, implementing actions rooted in community visions for the future and creating long-term, sustainable change.
For those looking for flexible online learning options, Coursera offers specialised courses and certificate programmes from institutions such as the University of Colorado Boulder, New York University, the University of Edinburgh and the University of Pennsylvania. These cover diverse areas, including climate modelling, environmental, social and governance (ESG) frameworks, and carbon footprints.
Among the beginner-level offerings is New York University's Climate Change and Human Rights, which allows learners to study at their own pace. The University of Pennsylvania also offers a four-week course on ESG and Climate Change, covering environmental, social and corporate governance, climate change adaptation and environmental laws.
As climate change and sustainability become increasingly central to public policy and corporate decision-making, the scope for careers in this field is expanding. Graduates and working professionals can explore opportunities in corporate ESG consulting, renewable energy, policy think tanks and environmental sciences. There is also a growing need for climate data scientists who can analyse environmental trends and help develop evidence-based solutions. Carbon auditing, too, is emerging as an important area, as organisations face increasing pressure to measure, monitor and reduce their carbon footprints.
