What is Climate Change?
• Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years).
• Climate change is largely irreversible.
• Climate change is attributed to GHG emissions from anthropogenic activities, biotic processes, variations in solar radiation received by Earth, plate tectonics and volcanic eruptions.
Effects of Climate Change?
• Higher Temperatures - the five hottest years on record have all occurred since 1997 and average surface temperatures could increase by 3 to 10 degrees Fahrenheit by the end of the century.
• Changing Landscapes - Changing temperatures are causing vegetation shifts and conservation challenges.
• Extinction of Species - One-fourth of the Earth's species could be headed for extinction by 2050 due to climate change.
• Rising Sea Levels - sea levels could continue to rise between 4 inches and 36 inches over the next 100 years displacing tens of millions of people.
• Increased Risk of Drought, Fire and Floods • Stronger Storms and Increased Storm Damage • More Heat-Related Illness and Disease • Declining crop yields

Steel Industry and Climate Change
Steel is versatile, strong and recyclable material and plays a significant role in the global economic infrastructure and development.
Steel as a product is eco-friendly; however steel making process
is associated with environmental ramifications, including energy consumptions & GHG emissions.
As producers of steel, it is our responsibility to meet the demand for steel in a safe and sustainable way, without compromising the need of the future generation.

Steel Industry and Climate Change
Steel Industry contributes about 6-7% of the total GHG emissions.

Paris Agreement--- Post 2020
• The Paris Agreement: An agreement within the United Nations Framework Convention on Climate Change dealing with greenhouse gas (GHG) emissions mitigation, adaptation and finance starting in the year 2020.
• The Agreement entered into force on 4 November 2016
• According to Article 4 paragraph 2 of the Paris Agreement, each Nation (Party) shall prepare, communicate and maintain successive Nationally Determined Contributions (NDCs) that it intends to achieve.
• India ratified the Paris Agreement on 2nd Oct 2016.
• Govt. of India has committed to reduce the GHG Emissions per unit of its GDP by 33-35% by 2030 from 2005 level.

Way Forward : Indian Iron & Steel Industry
• In consonance with this, Ministry of Steel has already submitted the Intended Nationally Determined Contributions (INDC) for reducing GHG emissions in Iron & Steel sector which inter alia projects CO2 emissions of:
• 2.2 -2.4 T/TCS in BF-BOF route
• 2.6- 2.7 T/TCS in DRI- EAF route
by the terminal year 2030, from 3.1 T/ TCS during 2005 for the overall steel industry.
10
Way forward for GHG Emissions
Mitigation
• Through Technology Deployment
• Improvement in Quality of Raw Materials
• Improvement in Fuel rate
• Increase in recycling & Reuse (4R principle)
• Promotion of Renewable Energy
• Afforestation for creation of Carbon Sink
11
National Steel Policy -2017
• The National Steel Policy projects production of 255 MT crude steel by 2030-31 & Finished steel per capita consumption of 158 Kgs by 2030-31.
• This automatically necessitates addressing Climate Change and Global warming issues as a major thrust area for the Iron & Steel Industry in India.
• As producers of steel, it is our responsibility to meet the demand for steel in a safe and sustainable way.

SAIL- Continued Commitment towards
Climate Change Mitigation
“Contribute towards mitigation of climate change through the adoption of cleaner
and energy efficient technologies.”
13
SAIL is committed towards mitigation of Climate Change and the same is reaffirmed in its Corporate Environment Policy also.
SAIL’s Initiatives to reduce GHG Emissions
Taken up various programmes for Climate Change Mitigation through: Technology up-gradation Integration of sound environmental practices Sourcing of good quality of raw materials
Retrofitting and revamping of old pollution control systems.
Specific CO2 emissions at SAIL has been reduced by more than 11% over last 10 years. 114

Introduction of Clean & Green Technologies
During recent modernization-cum-expansion of SAIL Plants, number of CO2 mitigation technologies have been implemented, such as:
• Coke Making:
– Tall Coke Oven batteries with Coke Dry Cooling Plant
– Computerized Combustion Control System
• Sinter Making:
– Waste Heat Recovery from Sinter Coolers
– Improved Ignition Oven Efficiency
Introduction of Clean & Green Technologies
• Iron Making (BF):
– Waste Heat Recovery from Stoves
– Top-pressure Recovery Turbine (TRT)
• Steel Making:
– Maximising BOF gas recovery.
• Rolling Mills:
– Walking Beam type Reheating Furnace
– Direct rolling of cast materials
– Use of regenerative burners for heating

• More than 53000 LED lights have been installed at SAIL plants/units including townships during last 4 years.
• More than 1.25 lakh more LED lights are planned for
installation at SAIL plants by 2023 for total switching over to energy efficient LED lighting system.

Our Greenery efforts
• Since inception, over 20.5 million trees have been planted to create CO2 Sink.
• 33% of land area covered with greenery.
• Plantation of 8.28 lakh and 4.42 lakh saplings was done across SAIL during 2017-18 and 2018-19, respectively.
• Target for planation – At least 5 lakhs saplings per year

Carbon Sequestration through Afforestation at
RSP
• Objectives is to assess CO2 generation, concentration in
surrounding ambient air, carbon sequestration of vegetation
and economic valuation and design & implement plantation
programme for additional carbon sequestration.
