Introduction

Carbon Trading represents a market-oriented mechanism for mitigating climate change, facilitating the exchange of carbon credits to control greenhouse gas emissions. Initially introduced under the Kyoto Protocol, it has become a central instrument in international climate policy, enabling countries and organizations to achieve emission reduction targets with greater efficiency (Tietenberg, 2006). It’s key models include cap-and-trade and carbon offset programs, which incentivize emission reductions through market mechanisms (Ellerman et al., 2014). With the Paris Agreement, carbon markets have expanded, supporting global decarbonization efforts and promoting cost-effective pathways to a low-carbon economy (UNFCCC, 2015; Sterner, 2003; World Bank, 2020).

Carbon Trading Concept

Carbon Trading, also known as emissions trading, is a market-based approach to reducing greenhouse gas (GHG) emissions. It allows countries or organizations with high emissions to buy “carbon credits” from those with low emissions, aiming to limit overall emissions in line with climate goals. This system was popularized under the Kyoto Protocol and is now also integral to the Paris Agreement’s framework.

Mechanics of Carbon Trading:

The fundamental concept of carbon trading lies in creating a cap-and-trade system. Regulators set a cap on total emissions, and entities are given or can purchase allowances representing the right to emit a specific amount of CO₂. Those who reduce their emissions below their allowance can sell excess credits, incentivizing low-emission practices. Over time, the cap is lowered, which is designed to gradually reduce emissions across the board (World Bank, 2021).

Carbon Markets are generally divided into two main types:

1. Compliance Markets: Market Created through regulatory policies like the European Union Emissions Trading System (EU ETS), these markets require participation from industries with high emissions, such as energy and manufacturing sectors.

2. Voluntary Markets: These markets are driven by companies or individuals seeking to lower their carbon footprint beyond legal requirements. Voluntary markets have been expanding as organizations commit to climate goals to showcase their dedication to environmental sustainability.

Benefits and Criticisms:

Carbon trading incentivizes emission reductions, enables cost-effective achievement of climate goals, and fosters investment in cleaner technologies. However, it faces criticism for potentially allowing wealthy companies or nations to avoid genuine reductions by purchasing offsets, sometimes resulting in insufficient action toward lowering actual emissions (UNFCCC, 2022).

Overview of Kyoto Protocol:

The Kyoto Protocol, adopted in 1997 and entered into force in 2005, was the first significant international treaty aiming to combat climate change by reducing greenhouse gas (GHG) emissions. It established legally binding targets for industrialized nations (also known as Annex I countries) to reduce their emissions by an average of 5% below 1990 levels over the commitment period from 2008 to 2012 (UNFCCC, 1998).

Mechanisms of the Kyoto Protocol:

The Kyoto Protocol introduced several innovative mechanisms to assist countries in meeting their emission reduction targets:

1. Emission Trading: Allowed countries with surplus emission allowances to sell these to countries that exceeded their targets, forming the foundation for the carbon trading market.

2. Clean Development Mechanism (CDM): Enabled developed countries to invest in emission reduction projects in developing nations, earning certified emission reductions (CERs) that counted toward their targets.

3. Joint Implementation (JI): Allowed industrialized countries to earn emission reduction units (ERUs) by investing in projects that reduced emissions in other industrialized countries.

These mechanisms provided flexibility and cost-effective solutions, encouraging international cooperation on climate action (World Bank, 2021).

Second Commitment Period and Limitations: In 2012, the Doha Amendment established a second commitment period (2013–2020) with revised targets, although this amendment faced ratification challenges, limiting its global influence. Moreover, critics noted that the protocol lacked enforcement mechanisms and exempted developing nations, resulting in some major emitters not being bound by reductions (Grubb et al., 2020).

Transition to the Paris Agreement: The Kyoto Protocol paved the way for the Paris Agreement in 2015, which expanded the scope to include commitments from all countries, not just industrialized nations. The Paris Agreement’s flexible structure addressed some limitations of the Kyoto Protocol, making it more inclusive and globally focused on long-term climate targets.
