THDCIL has a vision – to develop sustainable power with commitment to environment, ecology and social values.
As a responsible corporate citizen, THDCIL strives to control the environmental impact of it’s activities. Reduction of atmospheric emissions (especially greenhouse gases), measures for soil and water conservation, biodiversity protection, integration of facilities with their surroundings, reduction at source, reuse, recycling: the efforts extend to all aspects of reducing environmental impact.
In addition, impact studies are conducted for construction projects that are likely to affect the biophysical and human environments; mitigation, compensation and follow-up measures are also developed. To ensure that its actions are effective, THDCIL counts on sound environmental management systems.  ISO 14001:2004 (EMS) has been acquired for three projects namely Tehri HPP, Tehri PSP and Vishnugad Pipalkoti HEP.
THDCIL strategy on environmental sustainability is to optimize use of energy and water, to reduce carbon footprint and to protect/reconstruct Biodiversity.
THDCIL believes that Company’s business should be known not just for the financial results it generates, but for the imprint it leaves on the society as a whole and impact on the environment in particular.
The key environmental concerns affecting components such as land, water, air, flora and fauna are addressed in partnership with different stakeholders, i.e. public agencies, local communities, academic and scientific institutions, the investment community, and international development partners, harnessing their respective resources and strengths for environmental management.
After the Environment Impact Assessment, the Environmental Management Plan (EMP) is  prepared for the Project. Environmental Management Plan reflects legislative requirements, best practice guidelines and initiatives addressing the possible impacts and mitigation measures.
EMP is aimed at mitigating the possible adverse impact of the project and maintaining the existing environmental quality. The EMP converges all aspects of planning, construction and operation of the project, which are relevant to environment.
The Environmental Management Plan is reviewed to ensure that all environmental impacts are being addressed and that scope is being made for continuous improvements.
