Question

What are the differences between two policy strategies to mitigate \(\mathrm{CO}_{2}\) emissions, Clean Development Mechanism (CDM) and Joint Implementation (JI)?

Short answer

Answer: The major differences between CDM and JI are: 1. Participating countries and project location: CDM projects are implemented in developing countries, while JI projects take place within developed countries. 2. Emission reduction credits: CDM provides Certified Emission Reduction (CER) credits, while JI grants Emission Reduction Units (ERUs). 3. Project types: CDM focuses on projects promoting sustainable development and reducing emissions, whereas JI projects involve technology transfer and know-how between developed countries for emission reduction and energy efficiency. 4. Project approval procedures: CDM projects require approval from the host country's Designated National Authority (DNA), validation by a Designated Operational Entity (DOE), and registration by the CDM Executive Board. In contrast, JI projects follow either Track 1 (national procedures) or Track 2 (international verification) approach, with project approval and verification from the host country's authorities or the Joint Implementation Supervisory Committee (JISC).

Step-by-step solution

Introduce CDM

The Clean Development Mechanism (CDM) is a flexible emission reduction scheme established under the Kyoto Protocol, aimed at promoting sustainable development and emission reduction projects. It allows developed countries (Annex I countries) to finance emission reduction projects in developing countries (non-Annex I countries), and receive Certified Emission Reduction (CER) credits for their efforts. These CERs can be used by the developed countries towards meeting their emissions reduction targets.

Introduce JI

Joint Implementation (JI) is another mechanism under the Kyoto Protocol that enables developed countries (Annex I countries) to invest in emissions reduction projects within other developed countries (also Annex I countries). In return, they receive Emission Reduction Units (ERUs) for their efforts. These ERUs can also be used by the participating countries to meet their emission reduction targets.

Highlight differences in participating countries and project location

One major difference between CDM and JI is the countries involved and project location. While CDM projects take place in developing countries (non-Annex I countries), JI projects are implemented in developed countries (Annex I countries).

Highlight differences in types of credits and unit

Another difference lies in the type of emission reduction credits they provide. CDM grants Certified Emission Reduction (CER) credits, whereas JI provides Emission Reduction Units (ERUs). Both CERs and ERUs can be used by developed countries towards meeting their emission reduction targets.

Highlight differences in project types

CDM mainly focuses on projects that promote sustainable development and help reduce emissions, while JI projects mainly focus on acquiring or transferring technology and know-how between developed countries for reducing emissions and increasing energy efficiency.

Highlight differences in project approval procedures

CDM projects need approval from the host country's Designated National Authority (DNA) and validation by a Designated Operational Entity (DOE) before finally being registered by the CDM Executive Board. On the other hand, JI projects follow a different procedure, depending on whether the project utilizes the Track 1 (national procedures) or Track 2 (international verification) approach. Track 1 projects require approval and verification from the host country's authorities, while Track 2 projects require verification from the Joint Implementation Supervisory Committee (JISC). In conclusion, the major differences between Clean Development Mechanism (CDM) and Joint Implementation (JI) strategies to mitigate CO2 emissions are the participating countries, project location, nature of projects, types of credits, and project approval procedures.

Key concepts

Clean Development Mechanism (CDM)

The Clean Development Mechanism (CDM) is a pivotal part of the Kyoto Protocol, designed to lower greenhouse gas emissions globally while promoting sustainable development. It acts as a flexible tool allowing developed countries, classified as Annex I, to invest in emission-lowering projects situated in developing countries, known as non-Annex I countries. The most exciting aspect of CDM is that it creates a win-win scenario: developed nations can meet their emission reduction obligations by earning Certified Emission Reduction (CER) credits, while developing countries gain from sustainable development initiatives and technology transfer.

• CDM projects focus on fostering environmentally sustainable practices within developing countries.
• The projects can include renewable energy ventures, waste management improvements, or energy efficiency upgrades.
• Achieving CER credits requires the approval and registration of projects by a Designated National Authority (DNA) and the CDM Executive Board.

In short, CDM helps bridge the gap between economic and environmental needs across different nations.

Joint Implementation (JI)

Joint Implementation (JI) is another essential mechanism set by the Kyoto Protocol that emphasizes collaboration between countries to reduce carbon emissions. Unlike CDM, JI projects occur in developed countries, all of which fall under the Annex I category. This means a developed country can earn Emission Reduction Units (ERUs) by investing in projects in fellow Annex I nations.

• JI fosters technological collaboration and innovation among developed countries.
• The main objective is to enhance energy efficiency and reduce emissions within technologically advanced nations.
• Projects could range from advanced energy systems to industrial process optimization.

The verification and approval process for JI can follow either Track 1, which relies on national procedures, or Track 2, which involves international oversight by the Joint Implementation Supervisory Committee (JISC). This dual-track option makes JI a more versatile approach, ensuring that projects meet high standards.

Kyoto Protocol

The Kyoto Protocol is a landmark international treaty adopted in 1997 and enforced starting in 2005, after which it became a foundation stone for global efforts against climate change. Its ultimate purpose is to curb carbon emissions and blunt the impact of global warming by setting legally binding targets for developed countries to reduce greenhouse gas levels.

• The Protocol divides countries into two groups: Annex I, which are largely industrialized nations, and non-Annex I, which are primarily developing countries.
• It introduces market-based mechanisms, such as the Clean Development Mechanism (CDM) and Joint Implementation (JI), to help countries meet their targets cost-effectively.
• The Protocol has sparked a global conversation about climate change and brought about accountability in emissions reductions.

Under the Kyoto Protocol, the world began to see collaborative efforts between nations to combat environmental challenges efficiently and innovatively.

Certified Emission Reduction (CER)

Certified Emission Reduction (CER) credits are foundational elements in the functioning of the Clean Development Mechanism (CDM). These credits are awarded to projects in developing countries that successfully lower or prevent greenhouse gas emissions. Importantly, each CER credit equates to one tonne less of carbon dioxide emissions and can be traded or sold in emissions trading schemes, helping countries to fulfill their Kyoto Protocol commitments.

• CERs provide financial incentives for developing countries to engage in significant climate-positive projects.
• The credits enhance the credibility and viability of CDM projects by ensuring they meet international standards.
• They can be banked, sold, or traded for flexibility in how countries meet their emission reduction commitments.

By turning emission reductions into a quantifiable and tradable asset, CERs stimulate investment in green technology and global participation in reducing climate impacts.

Emission Reduction Units (ERU)

Emission Reduction Units (ERUs) are at the core of the Joint Implementation (JI) mechanism under the Kyoto Protocol. Like CERs, these units serve as currency within the emissions market. ERUs are awarded to developed countries that successfully implement projects aimed at reducing greenhouse gas emissions, following different procedural tracks - Track 1 or Track 2.

• Each ERU represents an equivalent reduction of one tonne of carbon dioxide emissions.
• ERUs can be used by developed countries to meet their international climate obligations under the Kyoto Protocol.
• The flexibility in the JI mechanism via the dual-track process broadens opportunities for participation and project execution.

ERUs not only encourage nations to refine and implement advanced technology but also promote cross-border energy cooperation, driving collective success in emission mitigation.
