Carbon Credits Register


Carbon credits serialization registry from GHG reductions of the Sustainable Community members which have been qualified, quantified, verified under the cluster of Quebec, Canada.

Sustainable Community is a project that has been developed, registered and validated in July 2013 under the VCS Program with the identification number 929


The use of a register allows each serialized carbon credit to be recorded individually and ensures the uniqueness (integrity) of the use of each GHG reductions that have been qualified under the Sustainable Community, then quantified, verified and converted to carbon credits. Maintaining a register, with all its relevant supporting documentation, makes it possible to address double accounting issues that are inevitable, and that can occur in several different ways such as those mentioned in our blog post of May 2019[1].

The use of a carbon credit register certified under the VCS program is an internal part of its program[2]. Following international public consultations held in summer 2018 and summer 2019, VERRA[3], the organization that manages the VCS program, updated the program in September 2019 under the name version 4.0. This more recent version provided for a transfer of external registers, previously managed by APX[4] or HIS Markit[5], to a centralized register which will be operated directly by VERRA.

Since the validation of the Sustainable Community project under the VCS program in 2013, WILL has used an external register to ensure the uniqueness of its serialized carbon credits. This external register for the whole period of 2013-2020 was previously managed by the firm APX accredited by the VCS program.


A Double Register System

Simultaneously, WILL operates and compiles the GHG reductions of its Sustainable Community project in its own internal register, since the very first verification in February 2014, which has made it possible to:

  • Conciliate the information that is entered in the APX register.
  • Ensure for each member of the Sustainable Community the distribution of verified carbon credits according to their geolocation, their micro-projects and vintage for the years 2010 to 2029.
  • Create and maintain the carbon asset portfolio (CAP) during summer 2019 for each member of the Sustainable Community, which will allow a fair and equitable distribution of the income from the sale of carbon credits in proportion to the verified efforts of each member.
  • The double register system (internal and external) optimizes the minimization of the risks of errors inherent in any single system.

Our Internal Register

WILL’s internal registry includes the recording of the results of new carbon credits issued following the 4th verification that cover the years 2017 and 2018. WILL’s internal register conciliates the supporting documentation as well as the quantities of GHG reductions which have been qualified under the Sustainable Community, quantified and verified by a third party recognized by VCS and which have been registered in the VERRA register since April 9th, 2020[7]. WILL’s register distinguishes, with consideration to the uniqueness of each carbon credit, between carbon credits serialized and registered under VERRA and carbon credits serialized and registered under WILL.

This double keeping of separate registers, always with a concern for social and environmental equity, makes it possible to connect the GHG reductions, qualified, quantified, verified which are prior to the current year of their verification by a third party[8]. This internal register makes it possible to identify, by means of a unique serialization, each carbon credit, which since January 1st, 2015, is subject in Quebec to discussion on their legitimacy [9]. WILL has also created a simple solution on this topic [10], with all respect for the integrity of the SPEDE and for the benefit of all Quebec stakeholders.
