The Greenhouse Gas (GHG) Protocol is the world’s leading framework for measuring and managing greenhouse gas emissions across Scope 1, Scope 2, and Scope 3, helping businesses accurately assess their carbon footprint. Widely adopted by sustainability standards such as CDP, CSRD, and the Science Based Targets initiative (SBTi), the GHG Protocol ensures consistency, transparency, and credibility in corporate climate reporting and emissions reduction strategies.

Regreener’s Carbon Calculator delivers reliable and actionable carbon footprint estimates by combining activity-based and spend-based methodologies—ensuring a practical balance between data availability and accuracy, aligned with GHG Protocol standards and suitable for audit-ready reporting.

Carrying out your own carbon assessment not only contributes to the global goal of reducing greenhouse gas emissions and combating climate change, but it also offers several strategic advantages:

• Meet customer expectations: consumers, especially younger generations, increasingly favor businesses that prioritize sustainability.

• Control operational costs: identifying and addressing inefficiencies can reduce expenses.

• Attract investors: sustainability initiatives can make your business more appealing to socially responsible investors.

• Enhance brand image: demonstrating climate action can strengthen your reputation and differentiate your brand.

• Prepare for future regulations: stay ahead of evolving environmental laws and compliance requirements.

We conduct our CO₂ measurements in accordance with the Greenhouse Gas (GHG) Protocol, the leading global standard for measuring and managing greenhouse gas emissions. Developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), the GHG Protocol provides comprehensive guidelines and tools for organizations to accurately measure, manage, and report their emissions.

Understanding GHG Protocol Scopes

The GHG Protocol categorizes emissions into three distinct scopes: Scope 1, Scope 2, and Scope 3. Here’s a quick breakdown:

• Scope 1 – Direct Emissions:
  These are emissions from sources that are owned or controlled by the organization. Examples include emissions from on-site fuel combustion, such as gas heating systems, company-owned vehicles, or industrial processes.

• Scope 2 – Indirect Emissions from Energy Use:
  Scope 2 covers indirect emissions from the consumption of purchased energy, such as electricity, steam, or heating and cooling. While these emissions occur off-site, they are directly tied to the organization’s energy consumption.

• Scope 3 – Other Indirect Emissions (Value Chain):
  Scope 3 encompasses all other indirect emissions generated across the organization’s value chain. These may include emissions from:

  • The production and transportation of purchased goods (e.g., IT equipment or office supplies)

  • Business travel and employee commuting

  • Waste disposal and logistics

  • The production of food consumed by employees
