9. Summary
- Table 9.1 Open ▸ presents a summary of the lifetime emissions of the Array, contextualised against the cumulative emissions of the transmission infrastructure. Net emissions of the Array only are calculated to be between 10,532,655 tCO2e and -131,667,016 tCO2e, and net emissions including the transmission infrastructure (i.e. for Ossian as a whole) are calculated to be between 13,608,654 tCO2e and ‑128,591,016 tCO2e. Note that negative values represent avoided emissions, i.e. emissions that would have occurred without Ossian.

[1] The Kyoto Basket of global warming gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3). The latter four are together termed ‘F-Gases’.
[2] As defined in IEMA (2022), material emissions sources are those that are greater than 1% of total emissions, and result from activities that do not significantly change the result of the assessment.
