The big question is how to decide and justify what you will measure? Linked to this is identifying where reductions could occur, and what you can do to actually achieve those reductions. And finally – is it even practical to try and measure those reductions?
Luckily there has been some guidance developed to help you make informed, relevant, possibly effective and definitely transparent decisions on what you should or shouldn’t include in the GHG measurements of your event.
Rules of Thumb
Events should include any greenhouse gas emissions that meet any or all of the following:
- GHGs created from activities where you have financial or operational control.
- GHGs which are estimated to make up more than 1% of your event’s total estimated GHG inventory.
- GHGs from activities that are deemed integral to the intended outcome of that event.
- GHGs that your stakeholders deem critical to be measured and disclosed.
- GHGs that the event could take action to reduce or influence potential reductions.
- Scope 3 GHG emissions that are large or relatively large compared to the estimated Scope 1 and 2 emissions.
Exclude GHGs if:
- evidence can be provided to demonstrate that such quantification would not be technically feasible, practicable or cost effective.
- they are estimated to make up less than 1% of total GHGs.
Assistance in justifying your inclusions and exclusions
Transparency and process are key in GHG measurement, carbon footprint determinations and carbon neutrality claims.
The first step on the journey is determining which ‘material’ greenhouse gas emissions will be included in your measurement scope.
We have created a downloadable and interactive PDF checklist to help you determine and justify what should be included and excluded in your event’s GHG emissions scope of measurement.
The potential GHGs are categorised by Scope 1 (direct), Scope 2 (indirect) and Scope 3 (other indirect) emissions. Tick Yes or No for each question, and include a short sentence to justify your inclusion or exclusion of the GHG source in question. Download the checklist
