Records from Mauna Loa, Hawaii (in parts per million by volume) show how CO2 concentrations in the atmosphere have increased since accurate records began.

The main greenhouse gases (GHGs)
The Convention concerns all greenhouse gases not covered by the 1987 Montreal Protocol to the United Nations Convention on Protection of the Ozone Layer. The focus of the Kyoto Protocol is on the following six:
●Carbon dioxide (CO2)
● Methane (CH4)
● Nitrous oxide (N2O)
● Hydrofluorocarbons (HFCs)
● Perfluorocarbons (PFCs)
● Sulphur hexafluoride (SF6)
The first three are estimated to account for 50, 18 and 6 per cent, respectively, of the overall global warming effect arising from human activities. The HFCs and PFCs are used as replacements for ozone-depleting substances such as chlorofluorocarbons (CFCs) being phased out under the Montreal Protocol

NOTE: N2 and O2 are not GHGs

United Nations Framework Convention on Climate Change (UNFCCC) was created in 1992 to deal with climate change, in particular to reduce GHG emissions.
UNFCC holds meeting of negotiators from countries, and the most important meeting is known as Conference of Parties (COP) held in December of every year.
In COP 3, negotiators met in Kyoto, Japan to work out a set of binding emission reduction target, and that is known as the Kyoto Protocol.

Joint Implementation (JI) Emissions Trading Clean Development Mechanism (CDM)
International Emissions Trading has come about from a unique historical event, i.e., the changeover of the Soviet block from a controlled to a market economy.
As a result of that many East European countries are emitting much less GHGs than prior to 1990 because their industrial activities have severely gone down.
Since the base year for Kyoto Protocol is 1990, these countries have emission quotas, which they can sell to other countries that have emission reduction targets.

The country where the project activity is located is called a host Party
GHG emission reduction unit (ERU) is issued against successful verification
The GHG reduction must be such that under regular activity it would not have occurred
ERUs can be used to meet KP commitments Both the countries participating in JI must
have emission caps implying that the total amount of emissions caps of Annex I parties will not change
ERUs will come into effect after 2008

What is CDM ?
Cost effective way of reducing greenhouse gas (GHG) emission
globally i.e.
Reducing GHG in Developing Countries instead of in Developed
Countries
Greenhouse Gas Mitigation

Need GHG credits Too Expensive in Country
Developing Country
Need Money + Technology Cheap to reduce GHG

HOW CDM WILL WORK?

What are baselines?
– X represents avoided tons in a given time period
– Actual project performance may differ from projected
– X1 represents CERs for the period

Investment Additionality
Financial Additionality
Overseas Development Assistance (ODA) cannot be used to finance a CDM project. This is essentially to prevent the existing development assistance from being used to purchase carbon credits. All CDM funds must be additional to the existing or future commitment of development funds
Sustainable Development criteria
![Page 23: Ijaz Hossain Chemical Engineering Department BUET ijaz@buet.ac.bd.](https://reader035.fdocuments.us/reader035/viewer/2022062221/56649f155503460f94c2a0cc/html5/thumbnails/23.jpg)
Project must not be financially viable, i.e., the
project IRR should be low. Projects that can be
executed without the financial support of the
CDM, should be excluded.
This criteria has, however, been relaxed.
Therefore, if the project proponent can
demonstrate that there are barriers that are
preventing the project from occurring
spontaneously, then it can be a CDM project.
![Page 24: Ijaz Hossain Chemical Engineering Department BUET ijaz@buet.ac.bd.](https://reader035.fdocuments.us/reader035/viewer/2022062221/56649f155503460f94c2a0cc/html5/thumbnails/24.jpg)
The sustainable development (SD) criteria attached to CDM has a curious history.
The concept of developed countries buying carbon credits from developing countries was severely criticized by many, terming it as a way of avoiding responsibility in own country.
The addition of the word ‘clean’ denotes that strict conditions must be met to execute a CDM project.
The SD criterion was thus added to the list of checks and balances to ensure that the project did not adversely the affect the host county, and that it actually promoted sustainable development.

Good historical data is not maintained in most developing countries
Because of widespread pilferage of electricity/gas and evasion of VAT, it is very difficult to get good data from private industrial and commercial establishments
Due to autonomous efficiency improvements, emissions in the baseline usually decrease over time; this need to be reflected in baseline
Small developing counties lack capacity to develop CDM projects because of its complicated structure

It failed to include the largest polluter , i.e., the USA
Some countries will not achieve the stated emission reduction target
The CDM has failed to deliver the desired impetus to emissions reduction
The land use sector was totally neglected
