  • Engaged Tracking (ET) Index Ltd reserves the right to update the ET Carbon Ranking Series as it deems appropriate.

  • Any member of the public is permitted to use the information provided in the ET Carbon Ranking Series for non-commercial purposes, provided that ‘Engaged Tracking’ or ‘ET Carbon Ranking Series’ is cited as a source.

  • Use of the ET Carbon Rankings is currently authorised for all forms of media dissemination. The use for academic, research and all other non-commercial purposes is authorised with prior written consent.

  • Reproduction of the ET Carbon Ranking Series and associated data for commercial purposes is not permissible without a license agreement from Engaged Tracking (ET) Index Ltd. This means that no data on the ET website can be sold, resold, transferred, assigned, distributed or otherwise commercially exploited or made available to any third party in any way without the prior written consent of Engaged Tracking (ET) Index Ltd.

  • The information provided in the ET Carbon Ranking Series is derived from publicly available sources but no guarantee can be offered to its absolute reliability.

  • Particular caution should be exercised when interpreting an inferred figure. This should not be considered an estimate of a company’s actual carbon emissions. The purpose of an inferred figure is only to incentivise disclosure by the company.

  • Engaged Tracking (ET) Index Ltd reserves the right to use inferred figures as a tool for incentivising companies to disclose information regarding their carbon emissions.

  • Wherever data is not complete, which means Scope 1 and 2 have not been reported for the company’s entire operations (or they have not been expressed in a sufficiently clear manner, or no public and freely available data is available) a worst case figure is inferred based on the highest reported emissions intensity by any company within the same industry, sub-sector or sector within the ET Carbon Ranking Series.

  • Engaged Tracking (ET) Index Ltd makes no warranty as to the reliability of independent third-party assurance.

  • Questions relating to the standard of assurance should in all cases be addressed to the company in question directly.
