Carbon Cycle

Page 3: Carbon neutral

Nature’s sources of CO2 are self regulating - which is released will be used again Plants take in and store CO2 from the atmosphere through photosynthesis Below ground microbes decompose organic matter and release organic carbon

back into the atmosphere

Anthropogenic carbon is not part of natures cycle (is in excess)

Role of Carbon in the Environment

• Carbon based molecules are essentially there in the biosphere

• Carbon (C) along with Oxygen (O2) constitute Carbon dioxide (CO2)

• 0.03 % of the natural atmosphere is CO2

• Plants use this CO2 to perform photosynthesis

• CO2 causes Green House Effect, which keeps the atmospheric temperature at 60°F

Then, how Carbon is a THREAT ?Emission from anthropogenic sources amplify the GHG

concentration in the atmosphere and hence the Greenhouse Effect causing Global Warming

What is Carbon Neutrality?

Net ZERO Carbon emission

Wikipedia : Carbon Neutral, or having a net zero carbon footprint, refers to achieving net zero carbon emissions by balancing a measured amount of carbon released with an equivalent amount sequestered or offset, or buying enough carbon credits to make up the difference.

Page 15: Carbon neutral

Carbon Footprint"A measure of the total amount of CO2 and 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)”

- journal Carbon Management by Wright, Kemp, and Williams

Page 16: Carbon neutral

Carbon Sequestration "The process of removing carbon from the atmosphere and

depositing it in a reservoir“-"Glossary of climate change acronyms“, UNFCCC

This may also be referred to as CO2 removal, which is a form of geo-engineering.

CO2 sequestration refers to large-scale, permanent artificial capture and sequestration of industrially produced CO2 using subsurface saline aquifers, reservoirs, ocean water, aging oil fields or other carbon sinks.

Carbon Offset

Collins English Dictionary : A compensatory measure made by an individual or company for carbon emissions, usually through sponsoring activities or projects which increase carbon dioxide absorption, such as tree planting

Wikipedia : A carbon offset is a reduction in emissions of carbon dioxide or greenhouse gases made in order to compensate for or to offset an emission made elsewhere

Page 19: Carbon neutral

Carbon Credit

A carbon credit is a generic term for any tradable certificate or permit representing the right to emit 1 tonne of CO2 or the mass of another greenhouse gas with a carbon dioxide equivalent (CO2e) equivalent to 1 tonne of CO2

a component of national and international attempts to mitigate the growth in concentrations of GHGs

1 carbon credit is equal to 1 metric tonne of CO2, or in some markets, CO2e gases

How to achieve Carbon Neutrality?

Reduce the Carbon Footprint till Zero net emission is achieved

If every individual does that, Global Carbon Neutrality will be achieved

Page 21: Carbon neutral

Steps to reduce Carbon Footprint

Measure the total Carbon Footprint

Setting the Target

Manage or reduce direct emissions

Offset the balance of what can’t be reduced

Page 22: Carbon neutral

Key sectors to be considered

Energy

Transport

Industry

Waste Management

Agriculture

Page 23: Carbon neutral

Reduction & Offset approaches

Efficient energy uses; better technology

Shifting towards Renewable energy sources

Introduction of Carbon-Capture technologies in large and small industries

Afforestation / reforestation International, national, local

level government policiesVoluntary initiative by the

common mass

Page 24: Carbon neutral

Approach from the grass-root level

At Individual LevelTurn off lights, television, computer etc. when not in use.

Use energy efficient appliances.

Fill the kettle with only as much water as you need.

Do your weekly shopping in a single trip.

Plant trees.

At the Office

No more plastic disposable cups! Let everyone bring in a mug or a glass from their home, and wash it in the restroom.

Power down when you leave, from lights to computers, everything should be off when you leave the office.

Page 26: Carbon neutral

Transportation

Use the bus or a train rather than your car.

For short journeys either walk or cycle.

Try to reduce the number of flights you take.

Next time you replace your car - check out diesel engines. With one of these you can even make your own Biodiesel fuel.
