What is climate change

What is climate change?

  • Climate change refers to any major change in the state of the climate that can be identified by changes in its measures (such as temp-erature, precipitation or wind) persisting for an extended period, typically decades or longer.

  • Climate change may be due to natural factors (changes in sun’s intensity)or natural process (changes in ocean circulation) or human activities that change the atmosphere’s composition (Ex. fossil fuel and forest & other vegetation burning) and the land surface (deforestation, reforestation, etc)

Cc climate change

  • Climate change

    is due to the

    global warming


  • Global warming

    is due to the

    Greenhouse effect

What is global warming

What is Global Warming?

  • Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface as well as in the troposphere, which can contribute to changes in global climate pattern.

  • Global warming, in common usage, often refers to the warming that can occur as a result of increased emissions of greenhouse gases (GHGs) (i.e., CO2, CH4, N2O, HFCs, PFCs, SFs and O3) discharged due to various anthropogenic activities.

  • Thus, now there comes the threat of climate crisis – a threat that is real, rising, imminent and universal(SPAN, March/April, 2008).

Greenhouse effect

Greenhouse effect

  • Natural greenhouse gas effect known for last 175 years

  • Fourier (1827)- “atmosphere acts like glass of hothouse because it lets through light rays of the sun but retains the dark rays from the ground”

  • These trace gases are transparent to incoming short wave solar radiation

  • But absorb the outgoing long wave terrestrial radiation and remitting this energy in all directions

  • Thus fundamentally altering the radiation balance of the earth atmosphere system

The greenhouse effect

  • These trace gases are transparent to incoming short wave solar radiation

  • But absorb the outgoing long wave terrestrial radiation and remitting this energy in all directions

  • Thus fundamentally altering the radiation balance of the earth atmosphere system

The global instrumental temperature record

The global instrumental temperature record

  • Quality instrument measurements begin about 1850

  • Global record shows approximately 1 °C increase over past 150 years

  • Note “Dust Bowl” peak around 1940

  • Warming is greater in Northern Hemisphere than Southern

Global warming up steadily

Global warmingup steadily

According to NASA’s GISS (Goddard Inst. Space Studies) –

  • Global temperatures have been steadily rising since the early 1980s with no significant let up in the trend

  • The over all warming trend has held through out this decade.

  • 2000-2009 was the warmest decade ever; and 17 of the 20 warmest years have been recorded in the last two decades.

  • The global temperature continued to rise rapidly in the past decade and there has been no reduction in global warming trend of 0.15-0.200C per decade that began in the late 1970s. The earth’s surface has warmed by about 0.60C since the last 1800s

  • April of was the hottest month ever and that the year 2009 so far was the warmest on record in India since 1901

  • As per NOAA, India has higher than normal temperatures all through this year, because of El Nino effect last year

Percent of ghgs contributing to global warming gw

Percent of GHGs contributing to Global warming (GW)

Kyoto Protocol recognizes six GHGs

  • CO2 (Carbon dioxide) [fossil fuel – coal, oil and natural gas; forest/vegetationburning; transportation]

    - 64 to 75 per cent

  • CH4 (Methane) [rice paddies, ‘managed ruminants’ –cattle, sheep, goats, buffalo & camels & oil extraction; coal mines] (24 times more GW potential than CO2) - 19 per cent

  • N2O (Nitrous oxide) [burning of garbage in dumping yards] (179 times more GW potential than CO2) - 06 per cent

  • HFCs (Hydrofluorocarbons) [aerosol propellants, air- conditioners, refrigerants, etc.] - 10.6 per cent

    - Hydrofluorocarbons (CFC gases are replaced

    by HFC coolants)

    - Perfluoro carbons(PFCs)

    - Sulfur hexafluoride(SF6) - 0.4 per cent

Carbon dioxide is the largest contributor

Carbon dioxide is the largest contributor

Hfcs save ozone layer but make world more warmer

HFCs save Ozone layer, but make world more warmer

  • CFC gases were widely used in air-conditioning and

    refrigeration units before they were found damaging Ozone layer, and were banned under the 1987 Montreal Protocol

  • Replaced by HFCs – hydrofluorocarbons - have far less effect on Ozone layer;but have been revealed as extremely powerful GHGs - The biggest source of HFC emission is air-conditioning in vehicles

  • One tonne of HFC-23 used in refrigeration has the same global warming (GW) potential as 14,800 tonnes of CO2

  • A tonne of HFC-134a, widely used in vehicle air-conditioning units, is equivalent to 1,430 tonnes of CO2; [N20 is 270 more potent than carbon dioxide]

  • It is warned that by 2050, HFCs could account for up to 19% of GW; by that time the contribution of HFCs to GW will be more than that of current global CO2 emission from houses and office buildings. Because, by 2050, the demand for HFCs is likely to increase by 800% compared with today’s figure

Total GHG emissions




















Between 1970 and 2004 Global Greenhouse Gas (GHGs) Emissions have increased by 70 %

Ghgs over the past millennium

GHGs over the past millennium

  • Exponential increase over the past 1000 years in CO2, CH4, and N2O is clear

  • CO2 concentrations have increased by about 35% since pre-industrial times

  • Methane concentrations have more than doubled

Source: 2001 IPCC report

Possible potential co 2 concentrations

Possible potential – CO2 concentrations

Estimates of future levels of co 2

Estimates of Future Levels of CO2

The average change in the amount of atmospheric CO2 over the last 600,000 years has been just 22 ppm. It is now uniformly distributed over the earth's surface at a concentration of about 0.033% (or 330 ppm)

(in clean air, it constituted 0.032%).

The atmospheric CO2 levels

Before Industrial Revolution - 280 ppm

1960 -317 ppm

1999 -368 ppm

2000 -369 ppp

Now i.e., 2008 - 380 ppm [It is rising roughly at a rate of

about 1 ppm per year]

It is projected that the global CO2 levels during

2010-2015 - 388-398 ppm {should be 350 ppm by 2050 to

2050-2060 - 463-623 ppm keep Temp. rise to within 20C}

India world s 3 rd biggest co 2 emitter

India World’s 3rd biggest CO2emitter

  • India figured 3rd in the list of biggest CO2 emitter through power generation after China and the USA (according to The Center for Global Development - CGD)

  • The National Thermal Power Corporation (NTPC) toped the list of companies emitting out the deadly Gas, though NTPC (New Delhi) said that they are the most efficient producers of power using fossil fuel.

  • Out of India’s 63,80,000 tonnes of CO2 emission every year, NTPC alone contributed 18,60,000 t that constituted 30 per cent of the total gas release

  • The NTPC power plant at Talcher (Orissa) emitted the highest quantity of CO2. As many as16 such plants are in CGD’s “red alert” category.

Cc climate change

Relative Amounts of CO2 Emission

  • Since 1890 – Industrial Revolution

    • Total CO2 emitted by all nations – 1201 gigatons (with world CO2 emissions being about 26 billion tonnes per annum)

    • The advanced economic nations – 700 gt (58 % of total contribution)

    • The USA alone emitted - 333 gt (28 %)

      {Industrialized nations must cut their emission by 25-40 % of their present rates by 2020, ten years from now}

    • All developing nations together - 501 gt (~41%)

    • India’ contribution only - 31 gt (03 % China’s

      contribution - 104 gt (09 %)

      In other words,

      India – 17 % of world’s population emitted 03 % (about 1/5 of that US)

      China – 20 % of world’s population emitted 09 %

      USA – 4.5 % of world’s population emitted 28 %

      Rich nations – 20 % of world’s populat. emitted – 76% global C

Relative amounts of co 2 emission

Relative Amounts of CO2 Emission

  • US citizens are biggest CO2 emitters

    - an annual average of 19.4 tonnes, while

  • Japanese emit 9.4 tonnes and

  • Indian emit 1.5 tonne

  • Ethiopean just 100 kg

  • Every adult just breathing produces about one kg CO2/day, which works out in average 4.3 tonnes of CO2 each year for every person on the planet

Where will future emissions come from

Where will future emissions come from?

  • The US and Western Europe are the current leaders

  • Developing countries (particularly India, China, and Eastern Europe) will contribute a much larger share in the future, because of use of coal

Temperature co 2 rise effects

Temperature - CO2 rise effects

  • When the CO2 was low, the temperature was low and there was an ice age

  • Between 1975 and 1999, the average temperature increased from 13.94 to14.350C, an increase of 0.410C or 0.740F in 24 years

  • The sea level has risenover the last century by 20 – 30 cm (8 – 9 inch). The climate models indicated that it could rise by as much as one meter During this century (It is exaggerated – recent view)

  • Sea level rise could create climate refugees by millions in developing countries – Bangladesh, India, China, Indonesia, Vietnam and Philippines

Cc climate change

Future C C impacts: ASIA

Melting of the Himalayan Glacier is projected to increase flooding, rock avalanches from destabilized slopes, and affect water resources within the next two to three decades, followed by decreased river flows as the glaciers recede.Freshwater availability in Central, South, East and Southeast Asia particularly in large river basins is projected to decrease due to climate change, which along with population growth and increasing demand arising from high standards of living, could adversely affect > a billion people by the 2050s.Coastal areas especially heavily-populated mega-delta regions in South, East and Southeast Asia, will be at greatest risk due to increased flooding from the sea

Cc climate change

C C IMPACT – Human Health

Scientists warned that at least a dozen “deadly” diseases – cholera, plague, sleeping sickness and eloba (among the dozen) are spreading across the Earth due to C C. These diseases are lethal to both humans and wildlife [the later could give an early warning of the approach of the disease]. The diarrhoeal disease primarily associated with floods and droughts are expected to rise in East, South and Southeast Asia. The relative risks for these conditions is expected to be the largest by 2030 .The excess mortality due to heat stress in India and China is projected to be very high;Europe could face an increase in disease outbreak carried by insects and rodents as climate changes and becomes hotter and wetter (EU health experts)

Cc climate change

CC IMPACT – Rise in Temperature on Disease Vectors like mosquitoes

-Rate of development (from egg to adults) will be faster- The densities of vectors will increase- Frequency of feeding and rate of digestion of blood meal will be faster- Frequency of egg laying will increase- Gonotrophic cycle [daily survival and man biting rates]and longevity for sporogony reduced at higher temperature - Death of mosquitoes at 400C

Cc climate change

CC IMPACT – Ecosystem and Biodiversity

-About 20 to 30% of animal and plant species assessed so far are likely to be at higher risk of extinction if rise in global average temperature exceeds 1.5 to 2.50C (According to The 4th Assessment Report of IPCC)- The impact is already seen on amphibians and plant life; it is expected to put increasing pressure on mammals too, by destroying their environment Example – Arctic ice sheets for polar bears- The extinct golden toad in Costa Rican jungles & two types of Harlequin frogs were due to C C; raising temp. favoured a dangerous form of skin fungus (infectious diseases) entering their habitats - Up to 50% of Asia’stotal biodiversity is at risk.

Cc climate change

C C IMPACT – Water Resources

- Gross per capita water availability in India would decline from ~ 1820 m3/ yr in 2001 to as low as ~1140 m3/yr in 2050- The projected decrease in the winter precipitation over Indian subcontinent would reduce the seasonal precipitation to three months [December to February] implying greater water stress- It leads to incidences of intense rainfall confining over fewer days implying increased frequency of floods during the monsoon; and direct runoff reducing groundwater recharging potential-More people are projected to be flooded every year

Cc climate change

CC IMPACT – Draught

- Recent increases in drought are due at least in part to man-made greenhouse gases- Widespread increases in drought are predicted likely to put stress on plants and water resources- General crop growth in India may increase (reason – increased rainfall)- BUT – extra rainfall also means increased flooding- However – some models predict decreased rainfall and therefore more damage to crops

Increase in moderate drought over the last 50 years

Mount kilimanjaro africa s tallest peak

Mount Kilimanjaro – Africa’s tallest peak

  • The snow capping Mount is shrinking rapidly

    1970 ->

    and could vanish altogether in 20 years, most likely due to global warming

    2000 ->

  • The ice sheet that capped the Mount in 1912 was 85% smaller by 2007

  • Since 2000 the existing ice sheet has shrunk by 26%

Third pole the himalayas

Third Pole – The Himalayas

  • These are the largest areas covered by glaciers and permafrost outside the polar region, and the area now being called the ‘Third pole’

  • The Himalayas have been warming three times faster the world average & their glaciers are shrinking more rapidly than anywhere else & could disappear by 2035.

  • The Glacier retreat in the Himalayas results from precipitation decrease in combination with temperature increase; and the retreat will increase up if climate warming and drying continues

  • This would affect Himalayan region and alter the lives of half a billion people in Asia and a quarter billion in China (IPCC 2007)

The third pole retreat

The Third Pole retreat

  • Recent studies showed that the mean temp. in the north-western Himalayas rose by 2.20 in the last two decades

  • The ‘Chorabari’ glacier, at about13,000 feet above msl is melting from inside – water gurgles under the ground or a tumbling stone breaking the silence of the mountains, a sign of glacier melting.

  • Chorabari’s snout has retreated 29.5 every year since 2004. It is melting faster than the rate at which snow and ice accumulates.

  • The ‘Parbati’ glacier, another largest in the area have retreated 170 feet a year during 1990s.

  • The snow line is gradually moving higher

Cc climate change

CC IMPACT – Glacier Melting & Sea Level rise

- Projected sea level rise could flood the residence of millions of people living in the low lying areas of South, Southeast and East Asia such as in China, Vietnam, Bangladesh, India - Even under the most conservative scenario, sea level will be about 40 cm higher than today by the end of 21st century and projected to increase the annual number of people flooded in coastal population from 13 million to 94 million.

CC IMPACT – Sea Level rise claims islands in Bay of Bengal

New Moore Island (also known as Purbasha Island) located on the confluence of Ichhamati and Rai Mangal rivers near the mouth of the sea remains almost perpetually submerged now, occasionally peeping out during low tides.This startling fact emerged from satellite images in 2009 and reconfirmed by ground truth – from fisherman that ‘there is no trace of the island any more’ (According to Prof. Sugato Hazra, Jadavpur Univ.)The island of Ghoramara, in the Hooghly estuary and Jambudeep near Bay of Bengal are also among other islands that are slowly sinking.T

CC IMPACT – Coral reefs in (GoM)

-The coral reefs, known as rain forests of sea, and included under ‘Schedule I’ of Wildlife Protection Act, 1972, at the Gulf of Mannar (GoM) is facing threat due to global warming and consequent climate change, because they are very sensitive- The impact of CC was clearly visible in 1998 in Indian Ocean with many reefs , previously regarded as near pristine, being seriously affected.- Annualbleaching was observed during summer every year since 2005 due elevated sea surface temperature- The maximum affected corals are in the shallow waters ranging from depths of 0.5 to 2 meters, and recorded on Shingle Island (Mandapam coast)- The most affected species are branching corals – Acropora nobilis, A formosa, Montipora foliosa and massive corals – Porites solida, Favia pallida

Cc climate change

CC IMPACT – Agriculture

- Indian agriculture is likely to suffer losses due to rise in temperature and erratic weather-Increased droughts and floods are likely to enhance variability in agricultural production- Considerable effects on microbial pathogens and insect pests- Rising temperature posing serious threat to diverse species of crops in India - Substantial decrease in cereal production in Asia. For e.g., 0.5o C rise in winter temperature would reduce wheat yield by 0.45 tonnes per hectare in India. - Greater loss expected in Rabi crops- Increasing sea and water temperatures are likely to effect fish breeding and harvesting;

Role of Forests in Combating CC: related to ‘Green India’

- By carbon sequestration or expanding the storage of C in forest ecosystems by increasing the area and/or C density of forests, and with reforestation- By conserving existing carbon (c) pools by slowing deforestation or improving forest harvesting practices - forest management- By lengthening C storage in forest ecosystems and in forest products – end use and land use management

Cc climate change

Agro-deforestation & C emission

According to a recent study (PNAS, 2010) – ‘Converting a forest or some scrubland to agricultural land causes a lot of natural carbon - C in that ecosystem oxidized, which is lost to the atmosphere’ (Dr. S. Davis, Dept. of Global Ecology, Carnegie Institute, Stanford Univ., California)These indirect impacts from converting forest & sc. land to farm land outweigh the direct GHGs emiss- ions that come from the modern and intensive style of agriculture i.e., the Green Revolution of 1960sThough modern farming uses more energy and agro-chemicals, much less land is cleared for it, leading to the loss of much less oxidized carbon (i.e., 160 GtC (billion tonnes) to 478 GtC matches up to 34 per cent)

- “FOREST” is defined by Land use, land use change & forestry (LULUCF)- as a minimum area of 0.05-1.0 ha (India 0.05 ha) with tree crown cover of more than 10- 30% (India 30%) with trees having the potential to reach 2-5 m (India 5 m) at maturity. - The Forests are both sources and sinks of carbon. Appropriate management practices can enhance their net sink values - “Afforestation” is conversion of land which has not been a forest for at least 50 years through planting, seeding and/or the human induced promotion of natural seed sources, while - “Reforestation” is raising forest on lands not containing forests as on 31.12.1989

Forests combat global warming

Forests Combat Global Warming

  • Suck CO2 from the atmosphere and store turning it into carbon in their trunks, branches and leaves as they grow; thus, help curbing global warming; so planting more trees helps counter some of the excess CO2 in the air.

  • The U. N., therefore launched a scheme in 2003 to plant one million trees to help counter deforestation

  • The ‘Future Forests’ group offset CO2 by investing in planting trees mainly in the Third World and has planted about 1,500 hectares of forest since 1999, from Scotland to Mozambique, to absorb 103,000 tonnes of CO2, against world’s annual CO2 emission of about 26 billions tonnes

  • Young and old trees have different albedo levels.

  • Young trees actively detonate carbon needed for their growth and development, while old trees absorb either little or no carbon at all.

  • Therefore, consequently new forests must be planted regularly to preserve a stable climate

  • Besides, we must care for old forests, protecting them from wildfire, and implementing well-thought-out tree felling programs

Other biological combating measures

Other Biological Combating Measures


  • It was also necessary to intensify biological processes in the world’s oceans – for example

  • Planktons, the perennial inhabitants of the seven seas, require and use huge amounts of CO2 for their growth, and should therefore be promoted and increased en masse with special biotechnologies.

  • Scattering/sprinkling iron filings in the ocean, fertilizing ocean water to nurture and promote carbon gobbling algae that would absorb CO2 from air and transfer it to the ocean depths -Prasanna Kumar et al., (2010)(Current Science, 101-106)

What is Geo-engineering ?

  • The concept of using technology to purposely cool the climate is called “Geo-engineering”

  • Without geo-engineering, it will be not be possible to avoid dangerous climate change

  • “Geo-engineering” describes large scale schemes such as – i. ‘Artificial trees’ to suck atmospheric CO2

    ii. enhancing the albedo of marine cloud by seedling them with cloud condensation nucleiiii. fertilizing ocean with iron to promote carbon gobbling algae

    iv. sowing the stratosphere with white particles or aerosols to reflect Sun’s rays or

    v. whitewashing or painting building roofs to reflect sunlight or

    vi. erecting sunshades or reflecting mirrors in space, and many such measures

‘Geo-engineering’ schemes are Solar Radiation Management (SRM) schemes and basically broadly fall into two categories:

i. One scheme controls how much sunlight or solar energy, to be more precise, reaches the surface of the planet

ii. The other scheme controls how much heat escapes back into the space, which depends on how much CO2 is in

the atmosphere

These can also be broadly categorized in to –

i. Biological and ii. Physico-chemical

  • “Artificial trees” can capture carbon 1,000 times than a real tree – according to Prof. KalusLackner, a physicist, at Columbia University, New York. Hehas been working on the project since 1998

  • The artificial ‘tree’ would be used to trap Carbon that has already been emitted into the air by car gasoline and airplane fuel; capture a ton of CO2 a day from air.

  • The tree is flexible in size and can be placed nearly anywhere. It is a ‘scrubber’ ‘scrubbing’ carbon from air

  • It works by collecting CO2 on a sorbent, cleaning and pressurizing the gas, and releasing it, like the way a sponge collects water, the sorbent collecting CO2.

  • Resin filters on top would capture CO2 from the ambient air


Geo engineering combating2

“Geo-engineering” Combating

  • The CO2 is then removed at the bottom using a series of moisture and compression steps – as per Dr Lackner

  • Each synthetic tree would absorb one ton of CO2/day, eliminating an amount of gas equivalent to that produced by 20 cars

  • Although the prospect of this is exciting, manufacturing such artificial tree structures would be expensive as each unit would cost about 30,000 US dollars to make, and would cost about $ 200 a ton CO2 to filter and store.

  • Prof. Lackner says that he will have a prototype with in three years i.e., by 2012.

  • These ‘artificial trees’ could be used in areas where carbon emissions are high

  • A forest of 1,00,000 ‘artificial trees’ could be deployed within 20 years i.e., by 2029 to help soak up world’s carbon emission

  • A unique scheme to cool the earth with increasing cloud reflectivity over the ocean by spraying them with an ultra-fine saltwater mist from ships (Sci. American)

  • The clouds containing more particles would cast enough sunlight back into space to at least partially offset the warming effects of all the anthropogenic CO2 present in the atmosphere

  • According to Prof. Stephen Salter of engineering design at Univ. Edinburg, the lead researcher, “marine cloud brightening could be done by populating the oceans of the world with up to 1,500 ships of a somewhat exotic design – sometimes known as ‘albedo yachts’


  • Each ship would be remote controlled, wind-powered, and capable of generating (via turbines dragged through the water) the electricity required to create a mist of seawater and loft it 1,000 meters in to the atmosphere

Orbital Solar-ray Reflectors :

  • Building Orbital Solar-ray Reflectors may eventually prove less expensive than the cost of global warming

  • Mirrors are to be installed at the L1 (La grande) point between earth and sun where gravitational forces balance each other; so that it is easier and cost effective to maintain

    Aerosols of Sulphuric acid and other Substances:

  • Spraying these aerosols i.e., of sulphuric acid or sulphate aerosols and other substances into the lower atmosphere at 12-16 km altitudes, as these are good reflectors

  • This will decrease sunshine reaching the Earth’s surface and reduce temperature in the troposphere by the required number of degrees, serving as an instrument of climate change

  • In 1974, Mikhail Budyko, member of Soviet Academy of Sci. and author of Global Warming Theory, proposed the aerosol-spraying method.

Geo engineering combating5

“Geo-engineering” Combating

  • It is also well known that after volcanic eruptions, surface temperature is reduced over vast areas because natural aerosols block sun-rays and bring down the temperature

  • Sulphuric acid or sulphate aerosol spraying could be carried out from specially equipped air-crafts.

  • According to YuryIzrael (Director, Inst. of Global Climate & Ecol. at Russian Acad. of Sci.), this is an optimal and inexpensive scenario in case of fast global warming.

  • It could be possible to change the situation in a year or several years at most.

  • Right now, a group of climatologists headed by Dr. Izrael is preparing to experiment to assess the impact of the aerosols on temperature fluctuation in some Russian areas

  • However, the method has some drawbacks – for exam., the stratosphere must be sprayed regularly because the aerosol will eventually drift to the ground and need to be replenished

Emission reduction

Emission reduction !!!

  • Few technological solutions, if any

    • No way to remove carbon fast enough (planting trees & crops too slow and requires a lot of water)

    • Nuclear power can help, but needs long time to build plants

    • Scrubbers can be built to remove CO2, but are very expensive

  • Only realistic guaranteed solution is dramatic - rapid lifestyle change

    • Lower, more efficient electric power usage

    • Reduced use of fossil fuels for transportation (goodbye to SUVs and large personal cars)

  • Lifestyle changes are very unpopular, but if not done reductions will be involuntary eventually

Lifestyle and behaviour patterns contributing to CC mitigation

There are many ways to adapt a ‘green’ way of life:- Using CFL (Compact Fluorescent Light) lights/bulbs at home: are energy efficient bulbs that consume less energy, though these are now expensive. - These bulbs use two-thirds less energy than a regular incandescent bulb and last up to 10 times longer - Each compact bulb keeps half a ton of CO2 out of air over its lifetime (According to The Natural Resource Defence Council, US-based mainstream environmental group) - But, all CFL bulbs need Hg to work and the compact versions contain about 5 mg of Hg (that’s not much - a home thermometer contains a 100 times of that amount, but when thrown along with MSW contaminate food-chain as it is persistent/hazardous; thus, the CFL bulbs after their lifetime, need proper and safe disposal)

Cc climate change

Lifestyle and behaviour patterns contributing to CC mitigation

- Eat less/little red meat (RM) as it is more energy intensive to produce; it takes so much of fossil fuel to grow, transport, and process the large amounts of feed that cattle require\- A vegetarian meals one day a week for a year (odwy) reduces emissions equivalent to driving 1,160 miles; an average family that eats chicken, fish or eggs instead of RM just odwy saves the equivalent of GHG emissions produced by driving 760 miles (According to a study Carnegie Mellon Univ., USA) - Covering glass windows with a film to block heat – another easy energy saving solution - “Travel together or car/bike pooling” – saves energy and money, and reduces pollution. - Several websites dedicated for car pooling in Hyderabad have come up – ‘’ - Such energy efficient solutions can be one of the keys to combating CC which can save the Planet

    • The project will displace the fossil fuel based grid electricity with the Hydel-based electricity, contributing to reduction estimated to the tune of 700585 t CO2eq (tonnes of carbon dioxide equivalent) per year. With a 7 year renewable crediting period, the project is expected to reduce approximately 14712285 t CO2eq, thereby generating equivalent amount of Certified Emission Reductions (CERs) for 21 years.

    • The power generated from HEPP will be supplied to northern Grid and hence would replace the electricity generated from thermal power stations filling into regional grid and also replacing the uses of diesel generator during shortage period.
