Measuring and Managing Emissions For a Greener Future

As governments, regulators, investors and customers place increasing emphasis on climate change, organisations are expected to understand and disclose their greenhouse gas (“GHG”) emissions with greater accuracy and transparency.

GHG accounting enables organisations to quantify emissions generated from their operations and value chain, providing the foundation for sustainability reporting, climate-related disclosures, emissions reduction strategies and Net Zero planning.

Whether your organisation is responding to regulatory requirements, customer requests or voluntary sustainability commitments, reliable GHG accounting is the first step towards effective climate management.

GreenCo provides professional GHG accounting and carbon footprint assessment services to help organisations measure, manage and report their GHG emissions in accordance with internationally recognised methodologies

Why is GHG Accounting Important?

Understanding your carbon footprint is no longer simply an environmental initiative,—it has become an important aspect of corporate governance, risk management and business strategy.

Comprehensive GHG accounting helps organisations to:

  • Meet sustainability reporting and climate disclosure requirements
  • Respond to investor, customer and supply chain expectations
  • Identify major emission sources and opportunities for emissions reduction
  • Support decarbonisation and Net Zero strategies
  • Improve operational efficiency through better resource management
  • Prepare for future assurance and regulatory developments
  • Demonstrate transparency and accountability to stakeholders

For many organisations, GHG emissions have become one of the most closely monitored sustainability performance indicators.

Supporting Evolving Reporting Requirements

Climate-related reporting requirements continue to develop across global markets.

Listed companies are increasingly expected to disclose greenhouse gas emissions as part of their sustainability reporting and climate-related disclosures. Requirements issued by stock exchanges and international reporting frameworks place growing emphasis on transparent, reliable and decision-useful emissions data.

GreenCo supports organisations reporting under a range of recognised sustainability frameworks, including:

  • HKEX ESG Reporting Code

  • SGX sustainability reporting requirements

  • IFRS Sustainability Disclosure Standards

  • GRI Standards

  • CDP Climate Change Questionnaire

  • Science Based Targets initiative (SBTi) preparation

Our consultants help organisations establish reporting processes that are practical, robust and capable of supporting evolving disclosure expectations.

GHG Protocol
International Standard

Greenhouse Gas Protocol

GreenCo applies the principles of the Greenhouse Gas Protocol, the world’s most widely recognised accounting framework for measuring and reporting organisational greenhouse gas emissions.

The GHG Protocol provides internationally accepted methodologies for defining organisational boundaries, identifying emission sources, selecting appropriate calculation approaches and reporting greenhouse gas emissions consistently across reporting periods.

Applying recognised methodologies helps organisations improve data quality, enhance comparability and support future assurance requirements.

Understanding the 3 Main Components

A complete greenhouse gas inventory generally consists of three categories of emissions.

Scope 3 Emissions

For many organisations, Scope 3 emissions represent the largest proportion of their overall carbon footprint and often require collaboration across multiple business functions and external stakeholders.

GreenCo provides technical advisory services covering all three scopes, from organisational boundary setting and emissions calculations to reporting and improvement planning.
