World Energy Consumption

Where does our energy come from?
Where does our energy come from?
Fossil fuels (Natural Gas, Oil, Coal)
Nuclear Power
Thermal Power
Hydropower
Wind Power
Solar Power
Landfill Methane (Biogas)
Renewable Energy
What is the connection between Energy and Carbon Dioxide?
What is the connection between Energy and Carbon Dioxide?
=Energy Use
CO2 makes up approximately
85 percent of total greenhouse
gas (GHG) emissions.
What is the connection between Carbon Dioxide and Global Warming?

What human activity produces the most greenhouse gases (CO2)?
What human activity produces the most greenhouse gases (CO2)?
Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2004, EPA.
1. Electricity Generation
2. Transportation
3. Industry
4. Agricultural
5. Commercial
6. Residential
The average person generates 94lbs of CO2 per day.
Climate Change
The Earth‟s surface is warmer than we might
expect considering the amount of radiation
reaching us from the sun.
Some gases in the atmosphere absorb infrared
radiation that has been emitted by the surface.
These gases occur naturally in the atmosphere
so our planet is warmer than expected and can
support life.
UNFCCC- 2015_Paris summit.
1st time in over 20 years of UN negotiations, the
COP 21 will aim to achieve a legally binding and
universal agreement on climate to keep global
warming below 2°C.
India‟s Agenda‟s:
'Polluter Pays Policy‟ (PPP)- by India
„Delhi to Paris: Corporate vision on climate
change‟
Carbon Footprint
“Total set of greenhouse gases emitted by an
individual, organization or product” (Carbon Trust 2008)
Carbon footprints are measured in tonnes of CO
2 equivalent or CO 2 e (and less commonly in
tonnes of carbon).
Example of the
breakdown of an
organisational
carbon footprint
Reasons to carryout Carbon Footprint
1. For publicly reporting greenhouse gas
emissions.
2. For setting a target for reducing emissions
3. To identify which activities contribute the most
to a footprint
4. In order to measure changes in emissions
over time, and to monitor the effectiveness of
reduction
5. To offset emissions
Types of Carbon Footprints
Organizational Assessment
Product Assessment
Other types of carbon footprints. Assessments
can be undertaken for events, services, web
sites, journeys, etc.
Calculating Carbon footprint
Collect Data from all utility meters and record the
energy consumption by organizations,
individuals, vehicles, etc.
Convert the fuel, energy, etc. consumption
figures to CO2 by using standard emission
factors. (Defra, Carbon Trust).

Carbon Reduction Solutions
What can YOU
do to reduce your
carbon footprint?
Carbon Reduction Solutions
Reducing CO2 emissions benefits:
• The environment
• The economy
• Society
Practices that benefit all three of these
are said to be sustainable.
