GHG Accounting in ECM

Before embarking on our journey to build Enterprise Carbon and Energy Management software, we decided that to build an enterprise solution, it would have to cater for as many greenhouse gas accounting, calculation and reporting frameworks as possible, in order for organisations to meet the highest number of legislative and international standards.

Standards that our ECM system currently supports include the GHG Protocol, Carbon Disclosure Project, ISO 14064, and the CRC Energy Efficiency Scheme. ECM supports all these standards simultaneously, and certain standards such as the CRC can be simply turned off.

The highest level standard that had to be considered is the Greenhouse Gas Protocol; a global accounting framework established  and maintained by the World Resources Institute and World Business Council For Sustainable Development.
 
The GHG protocol serves as the backbone of most global greenhouse gas reporting standards by setting out clearly defined boundaries, or “scopes”.
 
In ECM, we break the inputs and reporting into the three GHG protocol scopes:
Ghg_scopes
Scope 1 includes all an organisation’s direct GHG emissions; vehicles owned or leased by the organisation, directly consumed fuels and gas fired boilers that are usually metered.
 
Scope 2 includes indirect emissions though electricity consumption. These emissions are indirect as the actually generation is usually carried out by a third-party, but most of the result of that generation is consumed by the organisation through metered electricity.
 
Scope 3 includes indirect emissions and essentially accounts for everything else that an organisation consumes and in an ideal world will include the whole chain of suppliers, distributors and other products or services an organisation consumes.

As you can see from the first image in this gallery, total GHG (all scopes) 75.69 tonnes CO2, and as you cycle through the images you can see the amount of greenhouse gasses associated with each scope.

ECM also provides you with a view of scope emissions on a monthly basis:

In terms of other greenhouse gasses, our Enterprise Carbon Management solution also accounts for Methane (ch4) and Nitrous Oxide (N2O) where the data is available:
