3 Climate Change- Impact on Rajasthan District wise Projected Increase in Average Temperature in 2035 The average rise in temperature in Rajasthan projected by 2035 is in the range of 1.8º to 2.1ºC Increase in temperature will lead to increased evapotranspiration in the state. 1% increase in temperature from baseline data could result in an increase in evapotranspiration by 15 mm, resulting into additional water requirement mcm for entire arid zone of Rajasthan. Source-TERI report On Rajasthan 5 Climate Change- Impact on Rajasthan District wise Projected Increase Precipitation in 2035 No significant change in precipitation. The regional model estimates the mean annual rainfall to decrease slightly, but the extreme rainfall is expected to increase in frequency and intensity Source-TERI report On Rajasthan 6 3

4 Climate Change- Impact on Rajasthan Drought frequency Over last100 years, the probability of occurrence of severe and very severe droughts is high over the western Rajasthan region. Inspite of receiving high average rainfall the southern districts of Rajasthan have also experienced large number of severe droughts in the past. Source-TERI report On Rajasthan 7 Impact on Agricultural Sector Agriculture in Rajasthan is likely to face several challenges in the light of increasing competition for resources such as water, land and energy, from nonagricultural sectors, increasing food demand due to the rising population, increased use of fertilizers due to increased production demand and increased water withdrawals for irrigation from canals, wells and tube wells. Climate change poses formidable challenges to the animal husbandry sector as well. Heat stress in dairy animals is likely to impact their productive and reproductive performance. Reduction in feed and fodder availability due to changes in the climate can also affect livestock productivity. under conditions of declining water and fodder availability, household incomes of farming communities to decline drastically. 8 4

5 Impact on Business- Material Sector Companies Perceiving Risks due to Climate Change Source- CDP Report 2012 Opportunities Improved socio- economic conditions and increasing humanitarian demands will increase the demand for basic amenities like shelter etc, which in turn will push demand for cement, iron and zinc To diversify investment in clean power Risks generation options like wind mill Increase in operational costs due to water unavailability Risk of water stress due to conflict of interest between competent users Risk of business continuity through disruption in transport activities due to irregular rain pattern. 9 Energy and Carbon Policy Hindustan zinc acknowledges the global concern on climate change and recognizes that concerted and sustained global action is required to reduce the scale of the problem and to adapt to its impacts. Invest in clean energy and maximise benefits from wastes energy recovery adaption and future-proofing of our facilities 10 5

6 Green Energy Leading wind power generator in India MW of installed wind power mill MW MW MW Carbon Foot printing Registered 9 CDM projects- potential of 528,981 CER s. Carbon foot printing for FY Scope-1 emission (fuel): 46,19,113 MT of CO2e One projects process of registration Scope- 2 emission (electricity purchased): MT of CO2e Participation in Carbon Disclosure Project Scope- 3 emission (electricity purchased): 103,472 MT of CO2e (Bus commuting + Air travel) 12 6

7 Water Management Policy Hindustan Zinc recognizes the social, economic and environmental value of water and the increasing global and local concern of water scarcity. Water is a key resource and needs to be used responsibly, balancing the needs of many different users. Apply a zero discharge philosophy Application of best available techniques Participate in local or regional water catchment planning activities to secure sustainable water resources 13 Adaptation to Climate Change Adiabatic cooling towers in place of conventional water cooling towers in new Roaster at Dariba. Investment - Rs. 20 Crores Water conservation ~1000 cum/day Installation of Multiple Effect Evaporator, MEE Investment - Rs. 9.5 Crores Water conservation ~600 cum/day Enhancing efficiency of STP, ETP and RO plant Largest capacity of RO plants in Rajasthan CuM/day installed capacity Investment 80 Crores 14 7

9 Promoting Water Management beyond the Fence Drip Irrigation System Rain Water Harvesting Construction of 23 water tank, 45 water channels, 25 Irrigation wells, 05 check dams, 25 Rain Water Harvesting structures and linked with micro irrigation system. 17 Water Reduction In Operation & Environment Protection BEFORE TREATMENT AFTER TREATMENT Haul roads constructed with hard, low friability and wear and stress resistant material Regular water sprinkling Ligno-sulfonate based chemical is used as an additive in water sprinkled on haul roads to reduce dust by 90% and reduce water Consumption by 70%. 18 9

10 Climate Change - Way Forward Climate Change Management Reduce energy consumption Invest in renewable and energy efficiency projects to improve energy security, reduce GHG emissions, and reduce costs. Take proactive steps towards meeting emerging compliance requirements like PAT/ RPO. Climate Change Adaptation Reducing fresh water consumption by process optimization, reuse & recycling of waste water Use of less water intensive technology Harvesting Rainwater 19 Thank You 20 10
