CARBON FOOTPRINTPRESENTED BY-PRIYABRATA SAHUMBA(ABM) 1ST YRSABM,PJTSAU

WHAT IS CARBON FOOTPRINT?????

• A measure of the total amount of carbon dioxide (CO2) and methane (CH4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system or activity of interest.

• Calculated as carbon dioxide equivalent (CO2e) using the relevant 100-year global warming potential (GWP100).

Carbon dioxide (CO2) - 1

Methane (CH4) - 21

Nitrous oxide (N2O) - 310

Hydrofluorocarbons (HFCs) – 11,700

Perfluorocarbons (PFCs) – 6,500

Sulfur hexafluoride (SF6) – 23,900

HOW DO WE LEAVE A CARBON FOOTPRINT

Direct emissions of an item• Manufacturing process

• Electricity

• Transportation

Indirect emissions • Everything else

• Example: food,clothings buildings

SOME EXAMPLES

• A WEB SEARCH:

• Goggle estimates 0.2 g CO2e for the electricity it uses when you enter a search term

• 0.1g CO2e for 20 seconds of use from an efficient 20 watt laptop

• Local network and servers would use 0.1 g CO2e

• Maintenance on the whole system (replacing parts ect.) doubles the above figures

• Total = 0.8 g CO2e

• FOR A YR-5 TONS CO2E / YEAR / PERSON

• Banana powered bike• 53 kg CO2e

• Bus • 66 kg CO2e

• Small efficient car • 330 kg CO2e

• Plane • 500 kg CO2e

• Large SUV• 1,100 kg CO2e

Travelling 800 miles

SOME FIGURES

• THE GLOBAL AVERAGE CARBON FOOTPRINT IS ~6 TONS CO2E / YEAR / PERSON

• INDIAN AVARAGE-2.009 TONS CO2E / YEAR / PERSON

• GREEN HOUSE GAS EMISSION BY INDIA-2432.18 MT CO2E(5.7%)

IMPACTS OF A BIGGER CARBON FOOTPRINT

Environmental impacts

• Overall average annual temperatures are expected to increase.

• Global warming will decrease snow, sea ice and glacier coverage, resulting in rising sea levels and increased coastal flooding. Rising temperatures will also thaw permafrost in the Arctic.

• Storms and heat waves are likely to increase in frequency and severity.

• Many wild species will have difficulty adapting to a warmer climate and will likely experience greater stress from diseases and invasive species.

Human health impacts

• Increased temperatures and more frequent and severe extreme weather events could lead to increased risks of death from dehydration and heat stroke, and injuries from intense local weather changes.

• There may be an increased risk of respiratory and cardiovascular problems and certain types of cancers, as temperatures rise and exacerbate air pollution.

• The risk of water-, food-, vector- and rodent-borne diseases may increase.

Economic impacts

• Agriculture, forestry, tourism and recreation could be affected by changing weather patterns.

• Human health impacts are expected to place additional economic stress on health and social support systems.

• Damage to infrastructure (e.g., roads and bridges) from extreme weather events is expected to increase.

What Can We Do to Reduce Our Footprints

• TAKE ACTION @OFFICE;• Recycle glass, paper, aluminum and plastics.

• Buy recycled paper products and supplies.

• Telecommute if possible.

• Turn down the air conditioning.

• Install a programmable light timer that reduces light usage during off-peak hours.

TAKE ACTION@HOME;

• Replace a regular incandescent light bulb with a compact fluorescent bulb (CFL). Check for possible rebates from your utility company.

• Clean or replace filters on your furnace and air conditioner.

• Install window shading.

• Look for the Energy Star® label when choosing appliances.

• Use less hot water, by installing a low flow showerhead and washing your clothes in cold or warm water, instead of hot water.

• Turn off and unplug appliances not in use
