As the world grapples with an escalating climate crisis, among the most effective of tools for cutting global greenhouse gas (GHG) emissions is the use of carbon credits. These are credits that get businesses, governments, and individuals to offset their emissions by putting money into projects that cut or remove GHGs from the atmosphere. Carbon credits have found a place in international climate policy and markets, underpinning a market-based approach to climate action as we know it today.
But as the climate emergency escalates, carbon credits are increasingly called into question as being the world’s solution to climate targets. Carbon credits are a distraction from a solution, not a solution themselves, and critics worry about transparency, effectiveness, and equity. They believe carbon credits are a necessary bit of flexibility when it comes to achieving emission reductions, particularly in sectors that are too challenging to decarbonize directly.
In this article, we take a look at the ongoing arguments surrounding the effectiveness of carbon credits. It will then determine whether they can be relied upon as a first line of attack against climate change or whether their flaws necessitate a reconsideration of their place within future climate policy.
What Are Carbon Credits?
These carbon credits, also known as carbon offsets, are units of reduction of one metric ton of carbon dioxide or its equivalent of greenhouse gases (CO2e). The reductions can consist of diversifying towards energy efficiency or methane capture through avoided deforestation or renewable energy generation. Carbon credits enable businesses or countries to compensate for their emissions by funding projects that lower or capture carbon dioxide from the atmosphere.
Even though carbon credits are widely used, debate over whether they are effective enough to combat climate change has boomed. Proponents say they can fund meaningful environmental projects; critics counter that they offer a convenient excuse for polluters to not make real reductions in their own emissions.
The Case for Carbon Credits: These are flexibility and cost-effectiveness.
The advocates of carbon credits claim they are a practical and budgetary approach to reducing climate change. Carbon credits provide flexibility in meeting global emission reduction targets by allowing countries and companies to accomplish their targets by offsets, by investments, and by reductions of emissions in projects in other countries. The diversity in activities and industries around the world makes such flexibility essential. But there are several advantages when it comes to carbon credits in battling climate change.
1. Cost-Effectiveness
The main argument in favor of carbon credits is that they may be cheap. For lot of businesses, particularly those in the energy-intensive industries, reducing emissions might be too expensive. The purchase of carbon credits allows businesses to reduce emissions while fulfilling reduction targets at a significantly lower expense compared to internal measures of carbon reduction.
For instance, a company rooted in the fossil fuel industry could benefit from purchasing carbon credits embodying renewable energy or forest conservation at a lower cost than those of emission-cutting technologies. It enables businesses to get to their targets while sustaining the least financial impact to their operation from the cost of carbon credits by linking it to the market price of emissions.
Additionally, carbon credits are a cost-effective means for governments to meet mitigation objectives. In places where there isn’t much money, buying carbon credits as a way of fulfilling their international climate obligations might be cheaper than making big investments in the domestic side of emissions. It also allows nations with less capacity to be able to achieve climate goals.
2. Global Collaboration Encouraged
Carbon credits open up the option for countries to work together on a global basis to address climate change. The possibility to purchase the credits from the projects of emission reduction in the developing countries can help to create a more equitable system of climate mitigation in the regions where the high level of carbon emissions prevails, i.e., in the industrialized countries. Carbon credits can be a source of funding for sustainable development in less developed regions through such projects to advance the development of renewable forms of energy, conserve forests, and capture carbon.
Carbon credits provide a framework to link economic growth in the global South with climate action to create a shared responsibility for tackling the climate crisis. It can also go some way to healing some Cold War between developed and developing countries in terms of global climate negotiations.
3. Sustainable Projects Support.
Some of the most popular carbon credit projects exist to both reduce emissions and other types of co-benefits, including biodiversity conservation, improved water management, and even better air quality. For example, a reforestation project would sequester carbon, offer habitat to an endangered species, and improve soil health. Renewable energy projects can be a source for reducing emissions while providing access to clean energy for underserved communities.
These sustainable projects, however, often do not have the funding or political support to succeed and so are able to use carbon credits to provide the necessary financial support. Carbon credits can help move towards broader sustainability goals by allowing private investment in projects that bring environmental and social benefits.
The Criticisms of Carbon Credits: The Three Pillars That Impact Our Planet: Transparency, Additionality, and Long-Term Impact.
Held out as a way to improve carbon credits, practices are the advantages of carbon credits, yet very valid criticisms have been leveled against their power to combat climate change. Carbon credits are often touted as a ‘get out of jail free card’ for corporations and governments to continue polluting and not change their operations, the critics say.
1. DAK and Lack of Transparency and Accountability
But one of the most serious criticisms of carbon markets is that they lack transparency and accountability. Many projects that sequester carbon credits have been criticised for not doing what was supposed to happen in the way of decreasing emissions. It is difficult under this scenario to ensure that actual carbon credits are based on ‘legitimate, verifiable emissions reductions.
Even more opaque is the carbon credit market, which is naturally complex. Market by market, there are different standards and certification processes, and credits aren’t created equal. A good example is that a credit produced by a forestry project in one country may be verified in one way while the credit from a renewable energy project in another may be verified in another. But it’s hard to trust that the credits being bought are actually reducing global emissions if there aren’t consistent and transparent rules for how carbon credits are assessed in terms of legitimacy.
2. Adding and Real Emission Reductions
It is on this point that the credibility of carbon credits depends. Additionality is the idea that those emission reductions from a carbon credit had not otherwise occurred but for the financial investment that the sale of the carbon credit generates. In other words, that credit must not be an effort that didn’t occur in a “business-as-usual” scenario; rather, the credit must be a real, extra effort to cut emissions.
Proving additionality is, however, not easy. The credits are reductions that already would have happened, just without the marketplace. For example, a company that may have built a wind farm may have done that for economic reasons, rather than to harvest carbon credits. If such events were to become commonplace, carbon credits would be sold as real reductions when they wouldn’t be real reductions anymore, rendering the offset useless.
3. Risk of Reversal and Permanence
However, a larger concern regarding carbon credits, and especially those associated with land-based projects like forestry or soil carbon sequestration, is permanence. Not all emission reductions from projects like reforestation are permanent and can be reversed by natural events like fires, floods, pests, etc. When a forest that has been planted or conserved for purposes of carbon sequestration is destroyed, the stored carbon returns to the atmosphere, not counting its carbon credit.
The risk of reversal undermines carbon credits’ long-term effectiveness in delivering sustained reductions in emissions. Some crediting systems require “buffer accounts” to make sure that credits can be retired should the crediting turn out to be a reversal, but this doesn’t completely eliminate the risk.
4. The Risk of Greenwashing and Equity
Carbon credits have also been rapped for fuelling inequalities and ‘greenwashing.’ In some cases, richer countries or companies can still pump out large amounts of carbon without driving up the costs for themselves, buying carbon cuts from poorer countries or new markets where they are cheaper or easier to produce. That leaves countries and businesses responsible for most climate change free to offset emissions by what others do, rather than substantial action at home.
There is also alarm that companies will utilize carbon credits as marketing gimmicks to look green when in fact they don’t make substantial changes to their operations. For companies, by buying carbon credits, they could be able to say that they are ‘carbon neutral’ without tackling the actual causes of their emissions—burning fossil fuels, for instance, or being heavily reliant on supplies with a poor certification record.
5. Missing the Scale and the Systemic Change
But even with carbon credits fully transparent, additional, and permanent, critics say they cannot fill in the gap left by the systemic changes needed to address the scale of the climate crisis. Right now the carbon credit market is not big enough to make the global emission cuts needed, and it relies on voluntary participation that may not be sufficient for genuinely big change.
In addition, carbon credits all too often don’t confront the key causes of carbon emissions: unsustainable economic growth, overconsumption, and dependence on fossil fuels. The real work can’t just be on carbon credits alone to transform our world into sustainable and equitable models.
Are Carbon Credits Enough?
It is whether or not carbon credits will be enough to fight climate change that ultimately hinges upon how they are implemented and incorporated into the larger climate policy. Without massive amounts of carbon offsets, carbon credits alone are unlikely to fulfil the goals of the Paris Agreement or to avoid the worst impacts of climate change. While carbon credits can be important too in a low-carbon economy transition, they aren’t fit for use on their own; they should be coupled with direct reductions in emissions, carbon pricing, and investment in renewable energy.
In addition, strengthening regulations, improving transparency, addressing concerns about equity, and strengthening equity will also affect the effectiveness of carbon credits. To make the market more robust and accountable, the carbon credit market must come to be a transparent, defensible, transferable, and measurable entity based on real and lasting emissions reductions.
Overall, carbon credits can be an important part of the global solution to climate change but cannot themselves be relied upon as a one-stop solution to climate change. To achieve a sustainable and fair future, a holistic set of strategies to mitigate and adapt will be needed, such that systemic changes across the energy, transportation, and industry sectors are probable.
