Our Carbon Emissions Management


CO2As a business that primarily provides services, our company’s environmental footprint consists mostly of transportation, electricity consumption and use of communication and IT technologies. Other indirect emissions comes from our supply chain and embedded carbon from objects and material usage.

In 2013, we decided to closely examine our CO2e [1] emissions and establish a carbon management system. First, we identified all our possible carbon emission sources, their importance in our overall footprint and how they can be measured. We then prioritized the most significant and measurable sources of carbon emissions[2] and included them in our monitoring system as follows:

Resulting from our assessment, the following sources of carbon emissions have been included in our system for monitoring.

Scope / Activity

Type of emissions

Scope 1: Direct emissions

Not applicable[3]


Scope 2: Indirect emissions from the generation of purchased energy

(for work done at the office, staff home, public locations or client’s premises)

  • Electricity use for IT equipment such as computers and laptops

Work settings
(for work done at the office or staff home)

  • Electricity use for air conditioning and ventilation

Scope 3: All other indirect emissions that occur in the value chain

Commuting and travel
(public transport, taxi, plane)

  • Emissions from staff commuting to and from work
  • Emissions from trips to and from client’s offices, meetings and events
  • Emissions from air travel

Internet & communication

  • Embodied emissions of web usage (browsing, emails, webserver use, etc.)
  • Embodied emissions of phone communications

Meetings and events

  • Carbon emissions for hotel stay
  • Embodied emissions from beverage taken during meetings


  • All above emissions incurred by our 1st tier suppliers (consultants, partners)


  • Embodied emissions of purchased appliances and materials (computers, printers, paper, etc.)

Carbon measurement tool

To track our carbon emissions, we have developed a tool for reporting emissions for each activity listed in the table above. The tool is completed by our personnel for each project they support. Data on energy usage are obtained from different sources, primarily official documents, such as invoices or technical descriptions. Other factual information, such as time spent per activity and number of items consumed, are analysed with defined conversion factors and energy consumption averages to calculate realistic CO2e estimates.

We compile the total emissions for the whole company once a year. Factors and calculation methods are also reviewed annually.

In 2015, Ere-S emitted a total of 25 tonnes of CO2e



Ere-S is growing and so is our business activity. This means that we will most likely be generating more carbon emissions in the near future.

Although we do our best to minimise our energy and materials consumption (see our environmental policy), it is not possible to reduce many of our most significant emissions at this time. For example, we depend on the local public electricity grids and transport systems, which currently do not offer carbon-zero alternatives. Although we fly only when essential, air travel still represents by far the largest chunk of our total carbon emissions. Similarly, the majority of our other emissions are embedded and not under our direct control.

Within these limitations, and while real green alternatives become gradually available, we have decided to offset our carbon emissions. See our Carbon Offsetting page for more details.

[1] Equivalent carbon dioxide.

[2]  Activities representing less than 5% of our global emissions, air travel not included, were omitted.

[3] Ere-S does not have scope 1 (direct) emissions, such as use of fuel on-site. Only scopes 2 and 3 are therefore relevant in our case.
