Carbon Credits Vs. Offsets and When to Purchase Offsets

It’s Thursday!  Yay!

One more day to go.  As it’s Pizza Day in the Ring Household on Fridays, I’m incredibly excited to get to this part of the week.

Today, let’s solidify our understanding of carbon credits and carbon offsets.

I’d also like to extend my gratitude to our sister site, carboncredits.com, for making all this research available to me.

In Plain English, Please…

At their core, both carbon credits and carbon offsets are accounting mechanisms. They provide a way to balance the scales of pollution.

The big idea behind credits and offsets is that since CO2 is the same gas anywhere globally, it doesn’t matter where emissions are reduced.

It makes financial sense for both consumers and companies to reduce emissions where it is cheapest and easiest to do so, even if that does not involve their own operations.

Offset and Credit Similarities

At the simplest level, a carbon credit or offset represents reducing or removing greenhouse gas (GHG) emissions that compensate for CO2 emitted somewhere else. The instruments do have two primary attributes in common:

    1. One carbon credit or offset equals one ton of carbon emissions.
    2. Once a carbon credit or offset is purchased, and the CO2 is emitted, that credit is “retired.”  That means it cannot be sold or used again.

Carbon Offsets and Carbon Credits Defined

While the terms “carbon credits” and “carbon offsets” are often used interchangeably, they refer to two different products that serve two distinct purposes.

Before you begin purchasing either, it’s essential to understand the difference between the two and which one will help you meet your goals. Here is a broad definition of the terms:

    • Carbon offset: A removal of GHGs from the atmosphere.
    • Carbon credit: A reduction in GHGs released into the atmosphere.

To help visualize the difference, imagine a water supply that has been polluted by a nearby chemical plant.

A “chemical offset” would mean pulling chemicals out of the water to help purify it.

A “chemical credit” would mean paying another chemical company to release fewer chemicals into the water, so the overall pollution level stays the same.

Clear as mud? Great.

A Carbon Offset and Carbon Credit Primer*

Let’s dive a bit deeper into these products one at a time.

Creating a carbon offset involves a fancy term called “carbon sequestration.”

Recall how a judge can order a jury to be sequestered—meaning they must be sealed off from the outside world. It works the same way with carbon: offsets involve CO2 emissions being pulled out of the atmosphere and locked away for a time.

There is a growing list of ways to do sequester carbon.

These include planting forests, blasting rock into tiny pieces, storing carbon in manufactured devices, or capturing methane gas at a landfill.

The holy grail of carbon sequestration is using sophisticated technology to turn CO2 emissions into a usable product.

Carbon offsets are produced by independent companies that pull CO2 emissions from the atmosphere. The offsets are then sold to companies that emit (or have emitted) CO2.

Carbon credits, on the other hand, are generally “created” by the government.

Governments limit the amount of GHGs organizations can emit by placing a cap on them—a specific number of tons of CO2 the company can emit. Each of those tons is referred to as a carbon credit.

Companies comply with that cap by reducing the emissions produced in their operations through improving energy efficiency or switching to renewable energy sources.

An organization that brings its overall emissions below what is required by law can sell the excess credits to businesses unable or unwilling to cut their emissions to become compliant.

Carbon credits can be produced in a few other ways. For more detail, see our article on carbon credits.

The Two Carbon Markets

There’s one more important distinction between carbon credits and carbon offsets:

    • Carbon credits are transacted in the carbon compliance market.
    • Carbon offsets are transacted in the voluntary carbon market.

Mandatory schemes limiting the amount of GHGs that can be emitted have increased—and with them, a fragmented carbon compliance market is developing.

For example, the EU has an Emissions Trading System (ETS) that enables companies to buy carbon credits from other companies.

California runs its own cap-and-trade program, and nine states on the eastern seaboard have formed their cap-and-trade conglomerate, the Regional Greenhouse Gas Initiative.

The voluntary carbon market (think: offsets) is much smaller than the compliance market but is expected to grow much more prominent in the coming years.

It is open to individuals, companies, and other organizations that want to reduce or eliminate their carbon footprint but are not necessarily required to by law.

Consumers can purchase offsets for emissions from a specific high-emission activity, such as a long flight, or buy offsets regularly to eliminate their ongoing carbon footprint.

Do I Need Carbon Offsets or Carbon Credits?

Now that you know their differences and what they have in common, here’s how carbon credits and carbon offsets work in the grand, global scheme of emissions reduction.

The government is putting heavy caps on GHG emissions, meaning that companies will have to reconfigure operations to reduce emissions as much as possible.

Emissions that cannot be eliminated will have to be accounted for through the purchase of carbon credits.

Ambitious organizations, corporations, and people can purchase carbon offsets to nullify previous emissions or reach net zero.

So, which do you need?

If you’re a corporation, the answer is likely “both”—but it all depends on your business goals.

Carbon credits are unavailable to you if you’re a consumer, but you can “do your part” by purchasing carbon offsets.

Returning to our earlier illustration, the global goal is to stop dumping chemicals into the metaphorical water supply and purify the existing water supply over time.

Wrap Up

There are a few ways to look at this.

One is you can do well by doing good.  Another is “if you can’t beat them, join them.”

Whether you think climate change science is corrupted or there’s a legitimate reason for carbon offsets to exist, you can profit from this fantastic opportunity.

Tomorrow, I’ll wrap up this segment by discussing when to purchase carbon credits in the lifecycle and the importance of blue carbon credits.

Until tomorrow, have a wonderful Thursday!

All the best,

Sean

The 3 Investment Values

Starting at a young age, I had already decided I wanted to be rich. I quickly learned that to become rich I had to be willing to feel insecure and uncomfortable. There isn’t a right or wrong decision. If you’re not willing to give up your comfort or security for the sake of being rich, there’s nothing wrong with that. But, if that’s true for you, it’ll determine what type of investor you ultimately become.
