The Energy and Resources Institute (TERI) is a leading think tank dedicated to conducting research for sustainable development of India and the Global South.

TERI was established in 1974 as an information centre on energy issues. However, over the following decades, it made a mark as a research institute, whose policy and technology solutions transformed people's lives and the environment.

TERI's key focus lies in promoting:

  • Clean energy
  • Water management
  • Pollution management
  • Sustainable agriculture
  • Climate resilience



Creating Innovative Solutions for a Sustainable Future


Tackle issues of concern to Indian society, and the world at large, and develop innovative and cost effective solutions.

Enhance networking for sustainable interventions

Realize potential for national and international leadership as a knowledge based agent of change in the fields of energy, environment, other natural resources and sustain able development.

Inspire and reach out to diverse stakeholders for realising a shared vision of global sustainable development could be translated into action.

From research to practice and policy

TERI's efforts to develop clean lighting and cooking solutions have impacted the lives of nearly 4.5 million people who lived without electricity in rural India and parts of Africa-communities, whose incomes have improved with access to energy and who can now breathe better quality indoor air.

Nearly 600 small and medium enterprises in India have adopted a range of energy efficient technologies and practices promoted by TERI. These technologies, applied in key industries such as foundry, glass, forging, engineering and brick making, have altogether reduced energy consumption by 200,000 tonnes of oil equivalent (toe).

Elsewhere, small industries that struggled to cope with escalating bills of diesel or electricity now derive clean energy from TERI's biomass gasifier technology. Till date, TERI has deployed nearly 600 gasifiers for thermal applications in 15 sub-sectors, reducing the energy bills of these enterprises and providing a cleaner work environment to their workers.

TERI's water audits on the other hand have helped sectors such as thermal power plants, heavy engineering and railways to reduce water losses in the range of 20-40%.

TERI has provided green building advisory to nearly 200 buildings in India, in effect helping them to significantly reduce their energy and water consumption. TERI's rating system GRIHA, that measures the energy and environmental performance of buildings over its life cycle, now has 750 GRIHA registered projects in India.

Nearly 70% of oil refineries in India use the Oilzapper technology developed by TERI. Oilzapper, a bacterial consortium that degrades crude oil and oil sludge, has reclaimed thousands of hectares of contaminated cropland in different parts of India. TERI is now cleaning up nearly 2,40,000 sq meters of oil spills in Kuwait-the first-of-its-kind large-scale bioremediation project implemented by India's biotechnology sector.

TERI's mycorhizzal technology has made its mark as a commercially successful bio-fertilizer in India, Europe and North America. On the one hand, it is being used by large industries to reclaim toxic wastelands; on the other, it is helping to boost crop yields by nearly 25%, significantly curtailing the use of chemical fertilizers.

Over the last two decades, TERI's research has consistently supported the Government of India in global climate policy negotiations. TERI is among the few institutions in India with climate modelling capability to forecast climate risks at regional scales.

Last but not the least, TERI's programme on modelling and economic analysis helps policymakers to understand future scenarios across resources and sectors, and prioritize policy options for low-carbon based green growth.

Reaching out to diverse stakeholders

Recognizing the youth as an important constituency, TERI has reached out to nearly 25000 schools and 10000 colleges in India, through various programmes on environmental sustainability. In the sphere of higher education, TERI University has conferred postgraduate degrees on more than 1300 students in various disciplines of sustainable development.

TERI Press, the publishing arm of TERI, brings out journals, books and magazines for readers of all ages and attainments, and TERI's Film Unit produces films and videos that highlight human-interest stories related to sustainable development.

Every year since 2001, TERI has been convening one of the largest international summits - the Delhi Sustainable Development Summit, now elevated to the World Sustainable Development Summit - to provide a common platform to leading thinkers of the world to share and reiterate key messages on sustainable development.

In providing this diverse range of solutions and services, TERI's most valuable resource is its human capital. Its workforce of nearly 1200 people comprises scientists, sociologists, economists, and engineers who work together to design holistic solutions.

Over the years, TERI has also developed state-of-the art infrastructure, which includes facilities for mass production of bacterial and mychorrizal cultures and tissue-cultured plants, a supercomputing facility for climate modelling, and solar lighting and water testing laboratories. TERI maintains a specialized library and information centre on energy, environment, and climate change.

TERI is headquartered in New Delhi, with regional centres in Bengaluru, Guwahati, Mumbai, Panaji (Goa), and Nainital (Uttarakhand).

Beyond India, TERI has also actively promoted South-South Cooperation. It has implemented various projects in countries of Latin America, South Asia, South East Asia, and small island states.

A major part of TERI's income is generated from funds and research grants from multilateral and bilateral organizations, government agencies, grant-making bodies, and international academic institutions.

Now into the fifth decade of its journey, TERI's commitment to link its research to practice and policy is stronger than ever. Looking ahead, it aims to build new alliances and partnerships to spread its solutions across the globe to create a better world.
