NZE: Separating Climate Strategy from Climate Marketing

"Net Zero" has increasingly become a central topic in today's climate discussions around the world. Countries have announced it, companies have featured it on their websites, and even products are marketed around Net Zero claims.

Net Zero is, in fact, a scientific strategy that is essential for tackling global warming. However, in practice, the term is often used as a marketing tool—commonly referred to as greenwashing—when it is not accompanied by meaningful action.

What does Net Zero actually mean?

Imagine that every month:

- You deposit $100 into our bank account, 

- You also withdraw $100

at the end of the month, your balance is zero

The same principle applies to Net Zero. The atmosphere also has a "carbon bank account." Every year, humans release carbon emissions from power plants, vehicles, industries, aircraft, cement production, and steel manufacturing. If the total amount of emissions released is equal to the amount removed from the atmosphere, the final balance becomes:

Net = Zero

(Emissions released = Emissions removed)

Many ask, "Why can't we simply stop all emissions?" In theory, that sounds like the most effective solution. In reality, however, it is currently impossible as there are several sectors where achieving zero emissions is extremely difficult.

Even if the world's entire electricity supply came from renewable energy, many industrial processes would still produce CO₂. This is why Net Zero emphasizes reducing emissions as much as possible first, and only then offsetting the remaining emissions that cannot yet be avoided by removing carbon from the atmosphere.

Why Is Net Zero Controversial?

In recent years, this term has become a source of debate—not because the Net Zero concept is flawed, rather because of how some companies and organizations use it.

One of the most common misconceptions is the assumption that as long as total emissions can be "offset" through various means, a company can claim to be Net Zero. However, the primary goal of Net Zero is not to find ways to balance emissions on paper, but rather to reduce emissions as much as possible in the first place.

For example, a company may still produce millions of tons of carbon dioxide (CO₂) every year through its operations. Instead of significantly reducing these emissions, the company purchases carbon offsets, such as funding tree-planting or forest restoration projects, and then announces that it has achieved its Net Zero target.

Although projects like these can provide environmental benefits, many experts argue that carbon offsets should not be used as a substitute for direct emissions reductions. Trees take decades to absorb carbon, while emissions from burning fossil fuels are released into the atmosphere within seconds. Furthermore, not all offset projects are capable of removing as much carbon as promised or maintaining those reductions over the long term.

When Net Zero Turns into Greenwashing

Simply put, greenwashing is the practice to make a company, product, or organization appear more environmentally friendly than it actually is. This can be done through advertisements, product labels, sustainability reports, or marketing campaigns that emphasize a green image without any meaningful change.

For example, a company might promote the use of more environmentally friendly packaging, but at the same time continue to rely on production processes that generate significant carbon emissions. Others may announce a Net Zero target for 2050 but fail to provide a clear roadmap explaining how they plan to reduce emissions over the next five or ten years.

So, how can we distinguish between a genuine credible Net Zero target and one that's simply a marketing gimmick?

According to the guidelines of the United Nations High-Level Expert Group on the Net-Zero Emissions Commitments of Non-State Entities, there are several principles that demonstrate the credibility of a Net Zero target.

First, reducing emissions must be a top priority. Companies need to demonstrate concrete efforts to reduce emissions from their operations through increased energy efficiency, the use of renewable energy, or changes to production processes. Carbon offsets should only be used for emissions that cannot yet be eliminated with currently available technology.

Second, set measurable short-term targets. Committing to Net Zero by 2050 alone is not enough. Companies should also establish milestones for 2030 and 2035 so that the public can assess whether they are genuinely making progress.

Third, be transparent about emissions data. Information on total emissions, calculation methods, and progress toward emissions reductions should be publicly available so that it can be evaluated by stakeholders and independent organizations.

Fourth, ensure that business strategies align with climate goals. A company's Net Zero commitment is difficult to consider credible if it continues expanding investments in fossil fuel projects without a clear transition plan.

Ultimately, a credible Net Zero target is not simply about setting a target year. It is about demonstrating measurable actions and continuous progress. Transparency, direct emissions reductions, and accountability are what separate a genuine climate strategy from climate marketing.
