Carbon per million dollars of revenue. The legacy industry-standard reference (CDP, MSCI). Useful for cross-sector context, but distorted by margin — high-margin firms appear artificially efficient. Read alongside the operational and asset intensities for the full picture.

OpEx (operating expenditure) is the running cost of the business — staff, services, energy, materials. This shows how carbon-intensive operations are per million dollars of spend. Removes the margin distortion that revenue-based ratios introduce.

EVIC (Enterprise Value Including Cash) is the firm's total capital footprint — equity + debt + cash + minority interest. The EU's standard intensity measure (SFDR PAI 3) — answers: how much carbon does each million of capital deployed in this business produce?

PP&E (Property, Plant & Equipment) plus leased real-estate assets is the firm's physical infrastructure on the balance sheet. This shows the carbon intensity of that physical footprint — uses Scope 1+2+3 for consistency with the other headline intensities. Surfaces stranded-asset risk for asset-heavy firms.

Siemens Energy Group achieved powering 100% of its global electricity consumption with renewable sources in fiscal year 2023 and has maintained this into FY2025. The report does not detail the specific renewable procurement instruments (e.g., PPAs, RECs) used to reach this target for the Norway entity specifically, but frames it as a group-wide milestone central to the Company's sustainability strategy.

Siemens Energy is developing emission removal technologies as a long-term (beyond 2030) lever for Scope 3 downstream decarbonization, including a Direct Air Capture (DAC) demonstration unit agreement with Saudi Aramco intended to capture over 1,000 tons of CO2 per year and lay groundwork for a larger pilot plant. In parallel, the 'Forests of Siemens Energy and Siemens Gamesa' program has planted ~168,000 trees across 36 forests in 16 countries since FY2021, contributing to the removal of 23,900 metric tons of CO2 (nature-based, not distinguished from durable removals in company disclosure).
