"A lo largo de los años hemos invertido mucho en nuestro equipo de datos de campo, centrándonos en la elaboración de calificaciones fiables. Si bien esto garantiza la precisión de nuestras valoraciones, no permite la escala a través de los miles de proyectos que los compradores están considerando."
Para más información sobre las tendencias en la adquisición de créditos de carbono, lea nuestro artículo"Key Takeaways for 2025". Compartimos cinco consejos basados en datos para mejorar su estrategia de adquisición.

Una cosa más: los clientes de Connect to Supply también tienen acceso al resto de herramientas de Sylvera. Esto significa que puede ver fácilmente las calificaciones de los proyectos y evaluar los puntos fuertes de cada uno de ellos, obtener créditos de carbono de calidad e incluso supervisar la actividad del proyecto (sobre todo si ha invertido en la fase previa a la emisión).

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.
¿Cuál es el ciclo de vida de un crédito de carbono?
Los distintos registros utilizan un lenguaje diferente para describir su proceso de documentación y acreditación, pero el proceso es en gran medida el mismo en todos los registros. El siguiente diagrama describe el proceso general de compra y retirada de créditos de carbono.
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.
Los proyectos sólo pueden emitir créditos verificados basados en reducciones o eliminaciones de emisiones que ya se hayan producido. Un proyecto emisor emitirá créditos periódicamente, normalmente con varios años de diferencia debido al coste de la emisión de créditos y a los procesos de verificación necesarios.
Cómo evaluar un proyecto previo a la emisión
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.
