We recognise the importance of tackling the impacts of our legacy business, as locked-in emissions pose a significant transition challenge if left unaddressed. To guide progress toward our net-zero goals, we have set an absolute emissions reduction target for scope 3 emissions from gas sales, aiming to reduce emissions by ~67% by 2030 (baseline 2018) and by ~90% by 2040. To mitigate potential risks associated with locked-in emissions, we focus on measurable performance and avoiding additional locked-in emissions by not entering into new gas sourcing agreements that would contribute to additional locked-in emissions.

For the purposes of meeting financial materiality assessment requirements, we have also considered the following time horizons: short term (covering the current reporting year and the next year), medium term (from the end of the short-term period to five years), and long term (more than five years). Applying these horizons did not lead to any changes in the results of the assessment. It is important to note that, in the context of climate change, these time horizons are relatively short term and may not fully reflect the scale of risks that develop over extended periods.

Our physical climate risk assessment analyses data based on the remaining operational lifetimes of our assets, which extend up to 35 years. This period is considered medium term in climate projections, as significant climate changes are not typically observed in the short term. The long-term horizon, defined as 2060 onwards, is not applicable under our current methodology, as all existing assets are scheduled for decommissioning before that time.
