Carbon Emission

Carbon dioxide (CO2) makes up the largest share of “greenhouse gases”. The addition of man-made greenhouse gases to the Atmosphere disturbs the earth’s radiative balance. This is leading to an increase in the earth’s surface temperature and to related effects on climate, sea level rise and world agriculture.

The primary sources of greenhouse gas emissions are:

Transportation  – The transportation sector generates the largest share of greenhouse gas emissions. Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes. Over 90 percent of the fuel used for transportation is petroleum based, which includes gasoline and diesel.
Electricity production  – Electricity production generates the second largest share of greenhouse gas emissions. Most of our electricity comes from burning fossil fuels, mostly coal and natural gas.
Industry – Greenhouse gas emissions from industry primarily come from burning fossil fuels for energy, as well as greenhouse gas emissions from certain chemical reactions necessary to produce goods from raw materials.
Commercial and Residential  – Greenhouse gas emissions from businesses and homes arise primarily from fossil fuels burned for heat, the use of certain products that contain greenhouse gases, and the handling of waste.
Agriculture  – Greenhouse gas emissions from agriculture come from livestock such as cows, agricultural soils, and rice production.
Land Use and Forestry  – Land areas can act as a sink (absorbing CO2 from the atmosphere) or a source of greenhouse gas emissions.

The Kyoto Protocol has put in place three flexibility mechanisms to reduce emission of Green House Gases. Although the Protocol places maximum responsibility of reducing emissions on the developed countries by committing them to specific emission targets, the three mechanisms are based on the premise that reduction of emissions in any part of the globe will have the same desired effect on the atmosphere, and also that some developed countries might find it easier and more cost effective to support emissions reductions in other developed or dev

developing countries rather than at home. These mechanisms thus provide flexibility to the Annexure I countries, helping them to meet their emission reduction obligations. Let us take a look at what these mechanisms are.

What are the three flexibility mechanisms put in place of the Kyoto Protocol for reducing GHG emission?

  • The three mechanisms are joint implementation. Emissions Trading and Clean Development

What is Joint Implementation?

  • Through the Joint Implementation, any Annex I country can invest in emission reduction projects (referred to as joint Implementation Project) in any other Annex I country as an alternative to reducing emissions domestically.
  • Two early examples are change from a wet to a dry process at a Ukraine cement works, reducing energy consumption by 53 percent by 2008-2012; and rehabilitation of a Bulgarian hydropower project, with a 267,000 ton reduction of C02 equivalent during 2008-2012.

What is Clean Development Mechanism?

  • The Clean Development Mechanism (CDM) allows-‘l developed country with an emission reduction or emission-limitation commitment under the Kyoto Protocol to implement an emission reduction project in developing countries as an alternative to more expensive emission reductions in their own countries. In exchange for the amount of reduction In emission thus achieved, the investing gets carbon credits which it can offset against its Kyoto targets. The developing country gains a Step towards sustainable development.
  • To get a CDM project registered and implemented, the investing country’ has to first take approval from the designated national authority in the host countryestablish “Additionally”, define baselines and get the project validated by a third party agency, called a Designated Operational Entity (DOE).The Executive Body of CDM registers the project and issues credits, called Certified Emission Reductions (CERs), or carbon credits, where each unit is equivalent to the reduction of one metric tonne of. C02 or its equivalent. There are more than 4200 CDM projects in the pipeline as on 14.3.2010. The expected CERs till the end of2012 is 2,900,000,000

What is “Additionality” in a CDM project ?

  • The feature of “additionality” is a crucial element of a CDM project it means that the industrialized country that is seeking to establish the CDM project in the developing country and earns carbon credits from it has to establish that the planned carbon reductions would not have occurred on its own, in the absence of the CDM project. They have to establish a baseline of the project. Which is the emission level that would have been there in the absence of the project. The difference between this baseline level and the (lower) emission level achieved as a result of the project is the carbon credit due to the investing country

What are some of the concerns regarding CDM ?

  • The risk of “false Credits” is a cause for concern with regard to CDM projects. If a project does not actually offer an additionally and the reduction in emission would have happened anyway Even without the project.
