TL;DR

In the carbon market, the term "pre-issuance" refers to early-stage projects that have yet to issue carbon credits. Sylvera helps corporate buyers, investors, and other parties involved in the credit procurement process to find, track, and benefit from carbon projects thanks to proprietary frameworks and a commitment to transparency. In this article, we explain the lifecycle of a carbon credit, how to assess pre-issuance projects, and more.

Corporates of all sizes are going upstream to invest in pre-issuance carbon projects.

Put another way, more companies are funding projects early in the development stage, before credits have been issued. The goal? To secure high-quality supply. 

But to make quality investments, buyers need independent assurance of over-crediting, additionality and permanence risks from early-stage projects.

Discounting provides carbon market participants a way to utilize average-rated credits available today and account for imperfection. Investment in upstream projects, on the other hand, catalyzes the growth of high-quality credit supply.

The stage of a project in the crediting lifecycle can create unique risks and opportunities. Here's what you need to know.

Qual é o ciclo de vida de um crédito de carbono?

Registros diferentes usam linguagem diferente para descrever sua documentação e processo de crédito, mas o processo é basicamente o mesmo em todos os registros. O diagrama abaixo descreve o processo geral de como um crédito de carbono se torna disponível para compra e aposentadoria. 

It's important to keep in mind that it can take years for a project to get from the initial ideation, planning, and development phase to the stage where it can actually deliver credits to the market. (And even longer to actually impact climate change, depending on the project.)

Sylvera uses the terms Pre-Issuance Projects and Issuing Projects to distinguish between projects that have delivered verified credits to market and those that have not yet done so.

You may also encounter the terms ex-ante and ex-post. Ex-ante means “before the event”. In the context of carbon credits, the event is verification and subsequent release of credits by a registry. Ex-ante credits have not been verified or released to the market and, therefore, cannot be retired immediately. Purchasing them is a future-thinking strategy.

Ex-post means “after the event”. Ex-post credits are those that have been verified and released by a registry. These credits can be purchased and retired immediately. 

In the pre-issuance phase, a project's credits are entirely ex-ante. Based on the typical structure and cadence of the project lifecycle, an issuing project can have both ex-ante and ex-post credits.

The first major piece of documentation a project typically creates is one that defines the project design—for example, which methodology and modules are used, additionality, location, and other key data. In the early stages, the project developer will outline the expected volume of credits, typically defining the expected number of credits for each year of the project lifetime.

Os projetos só podem emitir créditos verificados com base em reduções ou remoções de emissões que já tenham ocorrido. Um projeto emissor terá liberações periódicas de créditos, geralmente com vários anos de intervalo, devido ao custo de emissão de créditos e aos processos de verificação necessários.

Como avaliar um projeto de pré-emissão

Sylvera's carbon credit Ratings are an ex-post assessment (i.e. conducted after the project has been up and running) of the quality of credits that have been delivered to market. They are updated at a regular cadence when new data is available, including when a project has a periodic issuance. 

However, projects at the pre-issuance stage face unique risks. Sourcing reliable projects, assessing claims and risks for each, and monitoring their implementation can be complex and time-consuming.

That's why Pre-issuance Ratings are used to make an investment decision and provide an indication of what Rating the project is expected to receive at issuance. This in-depth assessment is made up of 3 modules: ‍

  • Integrity: What rating this project is expected to receive at issuance
  • Delivery: How credits will be issued and when
  • Value: How this translates into money using our price rating correlation. 

Across these 3 modules, remedial actions provide guidance on how to improve the project's quality and value. Once remedial actions are taken, project stakeholders can progress with confidence, knowing their projects are optimized to generate quality credits that companies will pay a premium for.

So, for corporate retirees and investors looking to invest in these early-stage projects, Pre-Issuance Ratings can provide assurance and a sense of control because they give buyers a more reliable supply of credits and an opportunity to improve the quality of projects. (For financiers, it's an investment opportunity that looks a lot like more traditional project finance). 

How pre-issuance projects create high-quality credit supply

At Sylvera, our mission is to incentivize investment in real climate action. There is significant capital locked up on the sidelines, waiting to be invested in pre-issuance carbon credit projects. By using our proprietary frameworks to assess pre-issuance projects, we help investors identify the benefits and risks associated with these unique investments.

Upstream investments are essential to create the scale of high-quality supply needed to underpin corporate climate compensation and net zero action plans. Sylvera's independent assurance built on rigor, depth, and data is the momentum needed to unlock capital and set the flywheel in motion.

FAQs About Pre-Issuance Projects

What does pre-issuance mean?

For the carbon market, the term "pre-issuance" refers to the stage of the carbon project lifecycle before credits are issued. By investing in early-stage projects, corporate buyers and investors can secure quality credits at the best prices. But to succeed with this strategy, buyers need to understand project viability, i.e. collect sufficient proof that the project will eventually deliver the credits it claims it will. Sylvera's Pre-Issuance Ratings helps deliver this proof to buyers so they know which projects and credits to favor in their procurement strategies.

What are ex-ante and ex-post carbon credits?

Ex-ante carbon credits represent intended emission reductions. They are credits that have yet to be verified and released to the market. As such, they can't be retired immediately. Ex-post carbon credits represent emissions that have already been captured, verified, and released to the market. Companies that invest in ex-post carbon credits can retire them immediately to offset the GHGs they generate via normal business operations.

How does Sylvera help companies invest in quality pre-issuance projects?

Sylvera's Pre-Issuance Ratings give users access to comprehensive early-stage project insights that corporate buyers and investors can use to make better investment decisions. Our Pre-Issuance Ratings make an in-depth assessment of three modules: Integrity, which specifies the Rating the project is expected to receive at issuance; Delivery, which describes how and when the credits generated by the project will be issued; and Value, which explains how the project's credits can turn into money for your company. Our Pre-Issuance Ratings also feature remedial action reports that help project developers and/or early-stage investors identify and fix issues to generate higher quality credits and maximize project value. With Sylvera's Pre-Issuance Ratings, you can identify quality investment opportunities, mitigate risks associated with each project, and understand how every investment will impact your carbon portfolio.
