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.
