Carbon emissions are one of the most pressing global challenges today. Their impact not only accelerates the climate crisis but also forces companies across industries to comply with increasingly stringent emissions regulations.
One widely adopted approach to reducing emissions is through carbon credits or carbon trading. This market-based mechanism appears logical in theory. But is it truly effective? Let’s take a closer look.
What Is Carbon Trading?
Carbon trading is a market-based mechanism designed to control greenhouse gas emissions. At its core, the concept is quite distinctive: carbon emissions are no longer viewed as invisible waste, but as emission rights or credits with economic value.
Under this system, governments or regulators set an emissions cap. If a company emits less than its allocated limit, it has surplus allowances or emission credits that can be traded.
Conversely, companies that exceed their emissions cap are required to purchase credits from other parties to remain compliant and avoid penalties.
Here, the government plays a crucial role as rule-maker, compliance enforcer, and guarantor of transparency within the carbon trading system.

How Does Carbon Trading Work?
To understand the effectiveness of carbon trading, it is essential to examine the mechanisms commonly used in both global and domestic markets:
The Cap-and-Trade Concept
This is a system that sets limits and enables trading. Regulators establish a maximum emissions cap for specific industrial sectors. Emission allowances are then distributed or auctioned to companies.
If a facility successfully improves energy efficiency and emits below its assigned limit, it can sell its excess allowances to other companies struggling to reduce emissions.
Carbon Offsets and Carbon Credits
Unlike allowances, carbon credits or offsets are generated from projects that actively reduce, avoid, or remove carbon emissions, such as:
- Reforestation
- Renewable energy projects
- Large-scale energy efficiency initiatives
These projects must undergo rigorous verification processes by international standards such as Verra or the Gold Standard to ensure that the claimed emissions reductions are measurable and verifiable.
Implementation Examples Across Countries
One of the most established carbon trading systems today is the EU Emissions Trading System (EU ETS) in Europe.
Indonesia has also launched a national carbon exchange (IDXCarbon) and strengthened its regulatory framework through Presidential Regulation No. 110 of 2025 on the Implementation of Carbon Economic Value.
This regulation serves as the latest legal foundation for controlling greenhouse gas emissions and achieving national climate targets (NDC/Nationally Determined Contributions).

What Are the Benefits of Carbon Trading for Industry and the Environment?
Carbon trading aligns economic interests with environmental protection within a flexible market mechanism, allowing industries to contribute to emissions reductions without sacrificing competitiveness.
- Financial incentives: Emissions reductions can be converted into carbon credits with economic value.
- Flexible compliance: Industries can choose between reducing emissions directly or purchasing carbon credits as needed.
- Driver of low-carbon innovation: Pricing emissions encourages investment in clean technologies and process efficiency.
- Support for global climate targets: Directly contributes to NDCs and commitments under the Paris Agreement.
With a measurable, market-based mechanism, carbon trading acts as a bridge between industrial interests and the global climate agenda, strengthening the role of the private sector in accelerating the transition to a low-carbon economy.

Is Carbon Trading Truly an Emissions Solution?
Yes, carbon trading can be an effective tool for reducing greenhouse gas emissions. However, it does not stand alone. Its effectiveness depends heavily on policy design, regulatory strength, and consistent implementation on the ground.
Carbon Trading as a Tool, Not the Only Answer
Carbon trading proves most effective when it is part of a strict and comprehensive climate policy framework, rather than functioning as the sole emissions control instrument.
Clear emissions caps, consistent law enforcement, and meaningful penalties for non-compliance are critical to ensuring that the mechanism genuinely drives emissions reductions.
In practice, carbon trading works best when combined with other policies such as energy efficiency standards, renewable energy incentives, and restrictions on high-emission fuels.
Real Impact on Emissions Reduction
The actual impact of carbon trading on emissions reduction depends largely on policy design quality and the maturity of the carbon market.
Regions that implement progressively tightening caps, manage allowance allocations strictly, and enforce robust oversight tend to show measurable declines in emissions.
Conversely, systems with loose caps, excessive allowance allocations, or weak monitoring often deliver minimal impact. This underscores that the success of carbon trading lies in regulatory strength, not merely in the existence of a market mechanism.

What Are the Drawbacks and Challenges of Carbon Trading?
Despite its promise, several risks and challenges must be carefully managed in the implementation and oversight of carbon trading:
Greenwashing Risks
Greenwashing refers to practices where companies project an environmentally friendly image without making meaningful changes to their actual environmental impact.
In the context of carbon trading, there is concern that companies may purchase carbon credits solely to enhance their public image rather than undertake genuine emissions reductions.
Market Inequality and Access
Large corporations with strong financial resources often find it easier to purchase carbon credits as a compliance shortcut.
Meanwhile, smaller companies or developing countries face higher costs and capacity barriers, potentially creating unequal access within the global carbon market.
Carbon Price Volatility
Like other market instruments, carbon prices can fluctuate significantly. This volatility can undermine investment certainty and complicate long-term business planning.

How LNG Becomes an Alternative Within the Carbon Trading Framework?
Amid debates between market-based solutions and real-world action, many industries are turning toward emissions reduction at the source. One of the most practical options today is transitioning to Liquefied Natural Gas (LNG).
LNG is increasingly viewed as a viable alternative due to several advantages:
- Produces lower emissions and carbon intensity, approximately 40–50% less than coal.
- LNG use can reduce carbon costs by lowering total operational emissions, thereby decreasing the need to purchase carbon credits.
- LNG serves as a transition fuel for industries not yet able to fully shift to renewable energy due to technological or infrastructure constraints.
Within a carbon trading framework, LNG adoption is not merely a form of compensation. It is a proactive step toward reducing emissions at the source while maintaining business competitiveness in a low-carbon economy.
Carbon trading is not an illusion, but it demands high integrity to avoid becoming merely a numbers game. For industry players, relying solely on carbon trading is not enough.
A more strategic approach is to combine market mechanisms with tangible energy transitions, such as adopting LNG, to create cleaner, more sustainable operations.
