Climate Change- Impact on Rajasthan
5
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 evapo-transpiration in the state.
1% increase in temperature from baseline data could result in an increase in evapo-transpiration by 15 mm, resulting into additional water requirement 313.12 mcm for entire arid zone of Rajasthan.

6
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

Climate Change- Impact on Rajasthan
7
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.

Impact on Agricultural Sector
8
• 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.

Impact on Business- Material Sector
9
Companies Perceiving Risks due to Climate Change
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
generation options like wind mill
Risks
• 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.Source- CDP Report 2012

Energy and Carbon Policy
10
• 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

Water Management Policy
13
• 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

BEFORE TREATMENTBEFORE TREATMENT AFTER TREATMENTAFTER 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%.

Climate Change - Way Forward
19
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
