- Slight increase in operating emissions intensity in 2022 attributed to adverse weather conditions and operation of many rig power systems in an open bus configuration.
- Challenges in unified data reporting and meaningful comparisons of waste generation, water generation, and water consumption data due to varying requirements from region to region.
Transocean Ltd.
Greenhouse gas emissions & sustainability report data
In its 2022 reporting, Transocean Ltd. disclosed greenhouse gas emissions of 957.4K tCO2e/year. By scope: Scope 1: 66 tCO2e/year; Scope 2: 2.1K tCO2e/year; Scope 3: 931.1K tCO2e/year. Figures are as stated in the company's own report and may use different boundaries, units or methods (for example market-based vs location-based Scope 2), so compare with care.
