Slide 2: 

Greenhouse Gases Emissions of Top 5Human beings have burnt fossil fuels for last 200 years, and have emitted 2,84,31741 thousand tons of GHGs in atmosphere. 1. China / 20.7% – 30th rank in per capita emission 2. U.S.A. / 15.5% – 5th rank in per capita emission 3. Europe / 11.8% – 17th rank in per capita emission 4. India / 5.0% – 66th rank in per capita emission 5. Japan / 3.3% – 15th rank in per capita emission

Slide 4: 

Global Rise In Temperatures UN’s IPCC has reiterated that there has been a rise in average global temperatures to the extent of 0.73°C which is totally attributed to humans. The Copenhagen Summit (2009) tried to limit rise in temperature to 2°C by 2050 AD, but failed.

Slide 5: 

Rise in sea levels and loss of land Loss of Polar biodiversity Rise in number & intensity of hurricanes Extreme floods & water-logging

Slide 6: 

Extreme climate change is evident Before 1980-

Slide 7: 

..and now !

Slide 8: 

Global warming – a burning issue Earth is experiencing an unprecedented rise in average temperatures. Life of humans is threatened due to human generated emission of GHGs. Deteriorating air quality, water pollution, destruction of habitats, climate change, rising sea levels, & polar ice melting have threatened the human existence on this planet Every carbon footprint of each human will matter.

What is a carbon footprint? : 

What is a carbon footprint? Each one of us uses food, fuel, electricity, clothes, cosmetics, electronic goods, & many other consumer products. This consumption is a ‘footstep’ that leaves a footprint on the ‘floor’, i.e. the environment, thereby destroying many resources & life-forms under it.

Types of footprints : 

Types of footprints Each individual’s water consumption for his life-time, OR for an year, is his water footprint, that impacts water resources. Similarly, his wood consumption or plastic consumption also leave impacting footprints on the environment.

Slide 11: 

The most critical amongst these is carbon footprint. An indicator of human impact on environment. Measure of total direct, or indirect, GHG emission caused by a person during one year. CO2 equivalents of NO2 & Methane + CO2 itself, in tons /year/person together make up one’s carbon footprint. Average per capita footprint : World = 3.9 tons/CO2/year. / India 1.6 tons/CO2/year.

Why calculate individual footprints? : 

Why calculate individual footprints? Developed countries : Industries’ & environmental agencies’ own specific, carbon footprint calculators, pertaining to the specific realities of their production processes exist. India : No national authority to determine the extent of emissions from factors like railways, buses, cars, air planes, products, food production systems, food consumption patterns, life-styles, and / or public activities. Hence, individual Carbon Footprint calculators necessary.

Indian Carbon Footprint Footprint Calculator - Salient Features : 

Indian Carbon Footprint Footprint Calculator - Salient Features Major contributors: Energy consumption - Electricity, Cooking gas, kerosene, etc Transportation - Manufacture & Fossil fuel burning . Food consumption - Beef, Pork , Lamb, & Goat meat. Number in the household: Shared footprint-related aspects like power, gas, newspapers, food grains, oil, etc. to be apportioned equally amongst the number of people in the household above 13 yrs of age. (excluding the household helpers).

Carbon Footprint Electricity consumption : 

Carbon Footprint Electricity consumption 80% power generation is on fossil fuels. Electricity has invisible emissions from usage. Gadget Usage/yr Kg CO2/yr Micro. Oven - 96 times - 39 OTG - 135 times - 38 Dishwasher - 135 times - 84 Fridge - 24 hrs/day - 116 60 W bulb - 4 hrs a day - 63 18 W CFL - 4 hrs a day - 11 TV CRT 29 in - 6 hrs a day - 203 1 ton AC (8 hrs) = 85 km driving

Carbon Footprint Transportation : 

Carbon Footprint Transportation Besides the emission from the vehicle, the passenger load factor is important in calculation of the footprint. In a fully loaded bus, or any vehicle, passengers share equally the CO2 footprint of its journey. But if it is half full, then the per passenger footprint is doubled.

Carbon Footprint Milk consumption : 

Carbon Footprint Milk consumption Indigenous cattle, crossbred cattle, sheep and goats have to be reared for milk. Cattle feed cultivation, and fertilizer + manure application on land used for it, causes emission of Methane (CH4) & NO2. 1 ltr milk = 0.8 kg CO2.e Equal to 5 km driving.

Carbon Footprint Meat consumption : 

Carbon Footprint Meat consumption Meat production needs livestock farming. This necessitates animal-feed cultivation, manure & fertilizer use and dung disposal. Emission of Methane & NO2 is imperative. Cleared land reduces Carbon absorption. 1 kg mutton = 13 kg CO2.e Equal to 65 km driving. Average 750 gm/day meat is required for a family of 4.

Carbon Footprint Fish & Poultry status : 

Carbon Footprint Fish & Poultry status Fish and poultry are usually excluded. Fish farming does not require clearing of forests. Poultry requires much less feed per kg of meat produced. Absence of data on impacts of fish farming on global warming. This can be remedied in future when sufficient data is made available.

Carbon Footprint Rice consumption : 

Carbon Footprint Rice consumption India practices water incentive methods of Rice cultivation. So we have greater emission of Methane from our paddy crops than the world’s. 1 kg rice = 920 gm of CO2.e Equal to 5 km driving. Average 600 gm of rice is needed to serve 4 persons a single meal.

Carbon Footprint Utilities & Infrastructure : 

Carbon Footprint Utilities & Infrastructure All the industrial & commercial activity, public utilities and infrastructure exist for the service of the individual. So, an averaged proportion of the emissions related to these 'services' be attributed to individuals.

Carbon Footprint Fuels used : 

Carbon Footprint Fuels used Burning fuels like coal, petrol, diesel, CNG, LPG causes GHG emission. 1 ltr petrol = 3.17 kg CO2 .e 1 ltr CNG = 1.50 kg CO2 .e Footprint calculation relies upon price conversion to equate type, quantity & expenditure on fuel. To accurately calculate the footprint of a journey, the make/model of the vehicle, and its fuel economy value, has to be known.

Carbon FootprintTime and distance of travel : 

Carbon FootprintTime and distance of travel Greenhouse gas emissions per hour, from 2 or 4 wheelers in actual driving conditions are considered. (NPL & Bajaj Auto) Short, medium & long Bus or Train journeys are defined as: Short = up to 4 hours (between neighbouring cities) Medium = 4 to 12 hours Long = beyond 12 hours

Carbon Footprint Air travel : 

Carbon Footprint Air travel Airplanes use enormous quantities of aviation fuel. Take offs & landings needs alarmingly more fuel. 1000 km journey footprint: - Rail = 14 kg CO2.e /person - Car = 40 kg CO2.e /person - Plane = 110 kg CO2.e /pers. Single India – US trip creates an individual footprint of 2.6 tons of CO2.e A US round trip flight raises average per head footprint by 62%

Carbon Footprint Air travel : 

Carbon Footprint Air travel Impacts on climate are mainly attributed to aircraft fuels. Airport operations, ground services & catering services are not yet adequately studied for emission. Domestic airlines use a wide array of different aircrafts, so their emission results the same distance vary. Short flight = up to 45 mts Medium flight = 45 to 90 mts Long flight = above 90 mts

CO2 absorption by a tree : 

CO2 absorption by a tree For photosynthesis Trees absorb CO2. An average tree absorbs 12 kg of CO2 (UNEP Billion Tree Campgn.) Tree average life = 20 years So, it has a capacity of absorbing 240 kg of NO2-CO2 equivalent emission (or 0.25 tons of CO2.e approximately) Thus, a footprint of 1 tonne (1000 kg CO2.e) will require 4 trees to “neutralise” it.
