Blue Marble undertake all carbon accountancy exercises according to the globally accepted international standards.

The bulk of carbon accounting is working with ‘Organisations’. These organisations could be companies, charities, or even single events. In all cases we follow the Greenhouse Gas Protocol Standards supported by ISO 14064-1 Standard.

Using the most relevant and accurate emission factors is crucial to the calculation process. The majority of these emission factors are detailed within the DEFRA, BEIS and IPCC publications. This data is updated regularly.

The Greenhouse Gas Protocol Standards

GHG Protocol establishes comprehensive globally standardised frameworks to measure and manage greenhouse gas (GHG) emissions from private and public sector operations, value chains and mitigation actions.

Building on a 20-year partnership between World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), GHG Protocol works with governments, industry associations, NGOs, businesses and other organisations.

GHG Protocol supplies the world’s most widely used greenhouse gas accounting standards.

Objectives of the GHG Protocol
  • To help organisations prepare a GHG inventory that represents a true and fair account of their emissions, through the use of standardized approaches and principles
  • To simplify and reduce the costs of compiling a GHG inventory
  • To provide organisations with information that can be used to build an effective strategy to manage and reduce GHG emissions
  • To provide information that facilitates participation in voluntary and mandatory GHG programs
  • To increase consistency and transparency in GHG accounting and reporting among various organisations and GHG programs.
ISO Standards

ISO 14064 provides a solution to the problem brought to light in 2002 by the ISO Group on Climate Change. It observed that governments, business corporations and voluntary initiatives were using a number of approaches to account for organisation and project-level GHG emissions and removals with no generally accepted validation or verification protocols. In response, the Standards Council of Canada (SCC – proposed the development of ISO 14064.

The Standard used for calculating GHG emissions is:

ISO 14064-1:2018 – Part 1: Specification with guidance at the organization level for quantification and reporting of greenhouse gas emissions and removals

Objectives of ISO 14064
  • Enhance environmental integrity by promoting consistency, transparency and credibility in GHG quantification, monitoring, reporting and verification
  • Enable organizations to identify and manage GHG related liabilities, assets and risks
  • Facilitate the trade of GHG allowances or credits
  • Support the design, development and implementation of comparable and consistent GHG schemes or programs.
