1 Net promoter score is the number of promoters (giving a score of 9 or 10) minus the number of detractors (giving a score of 0 to 6) in our client care survey, expressed as a percentage.
2 Data includes energy consumption and business travel where available and covers 74% percent of our employees. We follow a standard procedure to handle missing data entries for energy consumption and business travel. Where data is not available, we use the monthly consumption for the month in the previous year. If this is not available, then we use the average monthly consumption for the current reporting year. If no data is available for the current year, we use the average monthly consumption for the whole of the previous year.
We have applied UK Government 2018 emissions factors (Department for Business, Energy and Industrial Strategy, 2018, https://www.gov.uk/government/collections/government-conversion-factors-for-company-reporting) and IEA 2017 emissions factors for electricity consumption in non-UK offices (www.iea.org). Scope 1 (direct) carbon emissions include natural gas, gas oil and fuel associated with company car travel. Scope 2 (energy indirect) carbon emissions include electricity consumed or purchased on behalf of tenants (less than 1% of scope 2 emissions). Scope 3 (other indirect) carbon emissions include business air, rail and private car travel.
3 Data includes offices where we have both energy and business travel recorded and covers 63% percent of our employees. We follow a standard procedure to handle missing data entries for energy consumption (see notes above). We apply emissions factors as detailed above.
