LIFE CYCLE INVENTORIZATION FOR COAL AND LIGNITE MINING IN INDIA

© Confederation of Indian Industry

Introduction to Coal Mining in India

v Coal is the most important and abundant fuel in India

¤ Accounts for almost 55% of the country’s energy need (29% is contribution world over)

¤ 70% of India’s Power generation is coal based

v India has the fifth largest coal reserves in the world

¤ Fourth Largest coal producer

¤ Estimated reserves of 308.8 Billion MT (as on 31.03.16)

¤ Coal reserves mainly confined to eastern and southern parts of the country

¤ Coal India Limited amounts for 84% of India’s total coal production

v Opencast coal mining contributes to almost 93% of total coal production in India

v In terms of Offtake of coal by various industries ¤ Power Contributes to more than 85% of total

offtake

v Underground mining contributes to the remaining 7 % of total coal production in India

v Estimated lignite reserves in India was 44.59 Billion MT (as on 31.03.16)¤ Tamilnadu and Rajasthan contribute 92.87%

v Installed capacity of coal washeries in India

¤ 131.24 MTY

Need for Preparation of LCI – Datasets for India

v Life cycle assessment is increasingly becoming an international tool for companies to assess their environmental impact

v Coal being one of the primary and most used industrial fuel becomes important input to various industrial process and products

v Power Generation , Cement , Iron & Steel etc. are some of the major industries having coal as a major raw material

v For these companies to asses their environmental impacts , it becomes necessary to refer the country (India) specific data sets

v Absence of India specific data sets lead to use of available global data sets for the same , which further leads to erroneous values for the study4

Major Stakeholders involved to be benefited by LCI for Coal Mining

v Coal Mining Companies ¤ Assessing their own environmental

performance

v Companies using coal as a major raw material ¤ Assessing the impact of coal in the

environmental performance of their own companies (LCA Study)

Objectives and Scope of the study – LCI for Coal Mining in India

v Preparation of India specific data sets for coal and Lignite mining operations, coal and lignite preparation

vNeed of the study ¤ Only global data sets

available¤ Referring the above data

sets for Indian conditions may lead to erroneous values for the users (for LCA studies)
