What is Carbon Neutrality?

While carbon neutrality has been a concept for decades, its prominence rose sharply following the 2015 Paris Climate Accords, where nearly every nation committed to economic and social transformations to mitigate climate change.

Private actors in business have developed entire industries around buying and selling carbon credits, renewable energies, and other carbon neutrality efforts. Individual companies have faced pressure from investors to work towards carbon neutrality and taken advantage of new market opportunities around climate mitigation.

This article unpacks the technologies, policies, and economic ramifications for reaching net zero emissions and potential decarbonization strategies available to investors looking to take advantage of climate mitigation.

Key Takeaways

• Carbon neutrality is essential for climate stability and involves balancing carbon emissions with removal through natural sinks and artificial technologies.

• Many organizations have individual commitments to carbon neutrality, using any number of strategies to offset their ongoing emissions.

• Strategies to achieve carbon neutrality include transitioning to renewable energy, enhancing energy efficiency, and adopting carbon offsetting initiatives, with both local and global efforts contributing to the commitment to reach net zero targets.

• There are challenges to carbon neutrality such as the controversy around carbon credits and the need for advancements in carbon capture technology.

Understanding Carbon Neutrality

At its core, carbon neutrality is about balance. It is achieved when the amount of carbon dioxide released into the atmosphere is offset by an equivalent amount removed, leading to a zero carbon footprint or, as it is often referred to, net zero. This balance is crucial in the battle against climate change, as achieving climate neutrality is key to limiting global warming to 1.5 degrees Celsius above pre-industrial levels.

Natural carbon sinks like forests, soil, and oceans play a vital role in maintaining this balance, absorbing an estimated 9.5 to 11 gigatonnes of CO2 annually. Despite their indispensable role, natural carbon sinks alone are not sufficient. As humans continue to emit more carbon, it becomes increasingly urgent to develop artificial technologies that can remove carbon from the atmosphere at scale.

How to achieve Carbon Neutrality

Achieving carbon neutrality is complex and multifaceted, requiring a well-coordinated approach. It involves transitioning away from fossil fuels to renewable energy, enhancing energy efficiency, and implementing carbon offsetting initiatives.

Let’s delve deeper into these pillars and understand how they contribute to the realization of carbon neutrality.

The Role of Renewable Energy

Renewable energy sources like solar and wind power have become crucial due to technological advancements, enabling a transition towards carbon neutrality. Innovations in energy storage technologies have been key to managing the intermittent generation from renewable energy sources, ensuring a reliable energy supply.

However, solar and wind are not the only pieces of the puzzle. Biomass, geothermal, and ocean energy, along with advancements in nuclear energy, are integral parts of the portfolio of renewable energy sources needed for carbon neutrality.

Carbon Offsetting Initiatives

Carbon offsetting initiatives have emerged as a critical strategy for achieving carbon neutrality. These initiatives allow for the reduction of emissions in one area to compensate for emissions elsewhere.

Such efforts are not confined to a local scale. The EU, for instance, has been enhancing its forests as carbon sinks to offset emissions, signifying a large-scale commitment to offsetting initiatives. Various projects, including forest conservation, afforestation, and expansion of renewable energy, enable the offsetting of unavoidable emissions, both locally and globally.

Some companies purchase hundreds of thousands of carbon credits, which allow them to invest in green energy initiatives whilst continuing to emit carbon dioxide, in theory balancing out to a carbon neutral operation.

Global Efforts and Commitments

The fight against climate change and the quest for carbon neutrality aren’t just individual or corporate endeavors. They require a concerted global effort. Over 140 countries, including major polluters, have set net-zero targets, covering around 88% of global emissions.

But how are these commitments being implemented, and what are the global initiatives driving us towards carbon neutrality?

Paris Agreement and Global Net Zero Emissions

The Paris Agreement, signed in 2015, is a landmark in the global fight against climate change. It aims to limit global warming to 1.5 degrees Celsius above pre-industrial levels, necessitating a 45% reduction in emissions by 2030 and achieving net zero by 2050.

However, while the percentage of countries with net zero commitments enshrined in law or policy has increased substantially, a gap remains between current plans and the required reductions to achieve net zero emissions commitments.

The top five emitters, which include China, the United States, India, the European Union, and the Russian Federation, collectively accounted for about 60% of global greenhouse gas emissions in 2021.

European Union's Climate Leadership

One of the leaders in the race to carbon neutrality is the European Union. With its Green Deal, the EU has set a legal commitment to reach a balance between CO2 emissions and removals by 2050, aiming to make Europe the first carbon-neutral continent.

In addition to setting ambitious goals, the EU has also been proactive in implementing measures to prevent companies from relocating their production to nations with more lenient greenhouse gas emission policies. The EU plans to implement a carbon border adjustment mechanism to address this issue.

Corporate Responsibility and Climate Action

While governments play a crucial role in driving the shift towards carbon neutrality, corporations also have a significant part to play. They can adopt carbon neutral goals, set transparent strategies for emission reduction, and align with UN Sustainable Development Goals.

Let’s explore how businesses are stepping up to the challenge.

Company-Led Emission Reductions

Many businesses are leading the way in emission reductions. They’re adopting strategies such as:

• Switching to green electricity

• Optimizing energy efficiency within their operations

• Investing in carbon offsets to neutralize portions of their emissions which are currently challenging to eliminate directly

Tools and initiatives that analyze and manage carbon risk across value chains aid businesses in their transition to low-carbon operations.

Aligning with UN SDGs

In addition to reducing their own emissions, businesses can align their strategies with the United Nations Sustainable Development Goals (SDGs). By doing so, they not only contribute to carbon neutrality but also improve their image and reduce risks associated with climate change.

Non-state actors, including businesses, are recommended to:

• Avoid financing new fossil fuel development

• Support strong climate policy

• Ensure that their business activities and investments do not contribute to deforestation.

The Controversy Around Carbon Credits

While carbon credits provide a mechanism to offset emissions, they have been the subject of controversy. Specific forest offsetting projects have been found to exaggerate their conservation impact and fail to lower forest loss substantially.

Scandals around overestimated environmental impacts of carbon credits have led to a loss of demand and declining prices for offsets. However, transparent verification mechanisms, like assignable ID numbers for carbon offsets, are crucial for enhancing the credibility of offsetting endeavors.

The effects of carbon credits also take time, delaying the true "neutrality" of some carbon neutral efforts. With a timeline of only a few decades, humans don't have the liberty of waiting years for carbon neutral initiatives such as tree planting and carbon sequestration to take affect.

Advancements in Carbon Capture and Storage

Innovative technologies are playing a significant role in the journey towards carbon neutrality. Metal-organic frameworks (MOFs), for example, are being studied for their potential in carbon capture technologies due to their large surface areas and high absorbency.

The development of negative emission technologies, such as bioenergy with carbon capture and storage (BECCS), exemplifies the emerging strategies that are essential for achieving net negative emissions.

The Future of Carbon Neutrality

Looking towards the future, achieving net zero by the mid-21st century is crucial to keeping global warming within a 1.5 degrees Celsius safe threshold, as outlined in the Paris Agreement of 2015. Although, more recent research published in 2023 has shown staying under 1.5 degrees is unlikely. The target now shifts to remaining as close to 1.5 degrees of change as possible, avoiding 2 degrees Celsius at all costs.

The economic benefits to achieving these emissions goals are twofold. Renewable energy is a relatively new sector with loads of financial opportunities. Additionally, the catastrophic effects of climate change, such as increased heat stress, lowered water availability, extreme weather events, and reduced biodiversity, will place extreme financial stress on governments and businesses around the world.

Summary

As we’ve explored throughout this blog post, carbon neutrality is a complex and multifaceted goal. It requires a balanced approach, combining renewable energy, energy efficiency, and carbon offsetting, backed by global efforts and corporate responsibility. Technological advancements in carbon capture and storage and the role of individual actions are also crucial in this journey.

However, the road to carbon neutrality is not without its challenges, as evidenced by the controversy surrounding carbon credits and the gap between current plans and required reductions. That said, the potential benefits of achieving carbon neutrality, both environmental and economic, make this goal worth striving for. After all, our planet’s future hangs in the balance.
