Greenhouse Gas (GHG) Inventory Services
Overview
A Greenhouse Gas (GHG) inventory is the first step that enables businesses to understand the carbon footprint of their operations. From this baseline assessment, organizations can make informed, data-driven decisions to manage impacts, optimize operations, and progressively reduce greenhouse gas emissions.
Based on the hands-on sustainability practices implemented across Oxalis Group’s operations, Oxalis Empowerment (a subsidiary of Oxalis) provides practical, operation-based GHG inventory services integrated with capacity-building training. We support businesses in identifying their emission profiles, defining feasible reduction roadmaps, and advancing toward long-term sustainable development towards Net Zero goals.
Why Does Your Business Need a GHG Inventory?
Conducting a GHG inventory allows businesses to move beyond sustainability commitments toward measurable and actionable outcomes. It establishes a data-driven foundation for long-term emission reduction strategies by:
– Identifying Key Emission Sources: Categorizing emissions into Direct (Scope 1) and Indirect (Scope 2 and Scope 3) sources, enabling businesses to optimize operational costs and improve efficiency in energy use, waste management, and resource allocation.
– Building a Credible Emissions Baseline: Creating a reliable data foundation for Sustainability Reporting, Net Zero planning, and continuous performance improvement.
Oxalis Empowerment’s GHG inventory services are implemented in accordance with recognized international standards and frameworks, ensuring Accuracy – Transparency – Comparability, including:
– GHG Protocol – the world’s most widely used standard for organizational-level GHG accounting.
– IPCC Guidelines (Intergovernmental Panel on Climate Change) – providing the scientific basis for emission factors and calculation methodologies.

A Carbon Footprint represents the total amount of greenhouse gas emissions generated by an activity, product, or service. Identifying a carbon footprint enables businesses to clearly visualize their environmental impact and implement appropriate improvement and emission reduction measures.
The carbon footprint concept is fully applicable to service-based business models. Oxalis has pioneered carbon footprint measurement within its own operations as the starting point of its sustainability and Net Zero journey.
Businesses interested in applying this approach may refer to Oxalis’ practical examples, where carbon footprint results are transparently integrated into service information:
- Carbon Footprint of Adventure & Cave Tours:

Service fees are structured as project-based packages and depend on several factors, including business scale, inventory scope, data complexity, and specific training or consulting requirements.
Oxalis Empowerment will propose the most appropriate and cost-effective plan based on the actual conditions and readiness of your business.
Typically, the GHG inventory process takes between 1 and 3 months, depending on data availability, data quality, and the selected emission scope.
For businesses with an existing and well-structured data management system, the timeline can be further optimized to meet specific operational needs.
Absolutely. Oxalis Empowerment places strong emphasis on step-by-step guidance and foundational training.
Businesses that are new to GHG accounting will be supported to implement the process in a systematic, practical, and effective manner, aligned with international standards.

No. It is not mandatory to cover all emission scopes in the initial phase.
Depending on business objectives, data availability, and control capacity, organizations may follow a phased approach – prioritizing direct emissions (Scope 1 and Scope 2) first, and gradually expanding to indirect emissions (Scope 3) when systems and resources are ready.
Yes. Oxalis Empowerment partners with businesses to analyze key emission sources and propose feasible, data-driven reduction solutions based on the results of the GHG inventory.
These recommendations are grounded in actual operational data and aligned with each business’s capacity and long-term sustainability objectives.
