XBRL > Climate Change Reporting Taxonomy (CCRT) due process

The CCRT Technical Working Group

For the development of CCRT a XBRL Technical Working Group was put in place, composed of both subject matter experts and technology experts. The TWG is currently composed of the following members:

Name Organization Area of expertise
Alan McGill PwC Subject matter
Brad Monterio XBRL Int. XBRL Int. Observer
Christine Condit Climate Registry Subject matter & technology
Craig Wong Climate Registry Subject matter & technology
Gordon Wilson KPMG Subject matter
Greg Soulsby XBRL Int. Technology – Bus. Requirements
Koizumi Makoto Fujitsu Research Institute Technology – Data architect (Technical lead)
Michael Piechocki BRAG Technology – Data architect
Pedro Faria CDP Subject matter & technology (Leading author)
Liv Watson XBRL Int. XBRL Int. Observer
Paul Hulst Deloitte Technology – Data architect
Josef MacDonald Independent consultant Technology – Project management

CDP and CDSB would like to thank the members of the XBRL Working Group and Fujitsu for their continued support and hard work in developing the Climate Change Reporting Taxonomy.

 Introduction

 

CDP and CDSB, along with CDSB’s members of the Board and of Technical Working Group (formed of representatives of large global accounting firms, their professional bodies, professional advisors and academics), share a common vision of a future where climate change disclosure will be a common feature of all business reporting and that it will ultimately be integrated with mainstream financial reporting.

Recognizing that regulators around the world are mandating the use of interactive data in XBRL format for electronic filing of statutory reports, these leading partners are committed to developing a taxonomy at an early stage so that data language can evolve alongside standards and practices for disclosing climate change-related information and so that stakeholders can provide input and guidance.

With this in mind, CDP and CDSB decided to initiate the process for the definition of such a Climate Change Reporting Taxonomy (CCRT). The CCRT initiative aims to develop a taxonomy that will be the representation of the most common reporting schemes so as to allow systems to process and communicate climate change data. In the longer term, the intention is that the data standard will establish the necessary links between financial business data and reporting and the new needs of information for a carbon constrained economy.

 

 Governance

 

The project is lead and set under the umbrella of CDSB and the organizations that actively participate in it. CDSB is responsible for launching the initiative and to make the initial draft scope and governance. The initiative will be supported by a secretariat provided by CDSB, or organizations collaborating with it and that will be in charge of preparing the agenda, website, management and distribution of documentation as well as arranging venues for meetings.

The Climate Change Reporting Taxonomy will be developed through a formal system of due process and with as broad consultation as possible. Its starting point will be the Climate Change Reporting Framework, developed by CDSB, and CDP’s 2012 Investor Questionnaire. However, its ambition is that it can become a general Taxonomy for any climate change reporting.

Proposed governance model for the Climate Change Reporting Taxonomy

The following governance model is proposed for the development of the Taxonomy (click to enlarge image).

The lead is CDSB board which oversees, reviews the effectiveness, appoint resources and finance the work done by CDSB Technical Working Group and CCRT XBRL project team (or Expert group). CDSB TWG is an existing body of CDSB and holds the subject matter experts which are responsible for the overall development of the Climate Change Reporting Framework. As such, their work informs the translation of CCRF by the Expert group into an XBRL Taxonomy.

The Expert Group will be responsible for development of the Taxonomy and support materials for the Taxonomy. It will be composed by members that will draft and authorship the taxonomy. It will cover two areas of expertise – technology and subject matter (climate change reporting). Technology experts will provide XBRL, taxonomy and ontology development, data architecture, business analysis, project management and development of XBRL tools. Subject matters experts will provide guidance on the translation of CCRF and CDP questionnaire in to the Taxonomy. Participation in the “Expert group” will be on a voluntary, non-remunatory basis. The elements of the “Expert group” will be initially appointed by CDSB. The “Expert group” will have a “leading author” that will be responsible for the deliverables of the group.

The Stakeholders Council (SC) is composed of individuals, or representatives of organizations, interested in the development of a climate change Taxonomy. It has the primary objective of providing strategic advice related to the Taxonomy development work. The objective is to provide a space where the Expert group can consult individuals and representatives of organizations affected by this work. The Expert Group will consult on issues which include, but are not limited to, the following:

  • Input on the Taxonomy architecture;
  • Input on the timetable, including priorities and consultation on any changes of plans and priorities;
  • Advice on projects, in particular practical application and implementation issues of the Taxonomy;
  • Advice on the due process for the Taxonomy development work, any changes that are deemed as necessary.

(Note: all working structures are currently working with exception of the stakeholder council with strategy/advisory responsibilities.)

To cover the costs of the work to be developed, organizations are invited to become “Sponsor organizations”. The details of sponsorship will be worked out with the organizations that express interest in it on an individual basis.

 

 Due process

 

Currently, there are no defined and generally accepted methodologies for XBRL Taxonomy developments however the process roughly corresponds to software development. The methodology proposed for the development of the CCRT follows closely the one implemented by the International Accounting Standards Board (IASB) for the development of International Financial Reporting Standards (IFRS) Taxonomy. This is considered best practice. CDSB convened an XBRL Technical Working group to oversee and inform the process, while providing consultation and feedback.

The Taxonomy development process will comprise the following phases:

  1. Planning and analysis
    • Preparatory work to guarantee success;
    • Initial requirement process, to define the scope of taxonomy, and use cases and a time line for deliverables; and
    • Milestones of Taxonomy development.
  2. Design
    • Taxonomy Architecture and data model set in accordance with the best practice and existing technologies.
  3. Taxonomy building or implementation
    • Iterative process developed in consultation with technology and subject matter experts;
    • Small cycles of testing that will validate conformance with XML and XBRL specifications and best practice; and,
    • Conformance with requirements and use cases; testing with artificial climate change data; testing with real life climate change company reports.
  4. Taxonomy consultation
    • Exposed publicly for a minimum period of time of 30 days; and
    • Where possible, the consultation of the Taxonomy will also comprise live demonstration of the concept to key companies.
  5. Taxonomy publication and maintenance
    • Once comments from the consultation stage have been considered, the final XBRL Taxonomy is published, together with any support materials
