Our online calculator will work out your share of emissions created by your meetings in our hotels. The calculation is based on the number of guests and the length of your event.

How is it calculated?

Carbon emission is calculated from the specific conversion factor for each Langham hotel (the amount of carbon dioxide emitted per guest night). This conversion factor is calculated based on their energy consumption and guest nights data based on the previous year. Energy consumption comes from a mix of energy sources (electricity and gas). Guest night represents the total number of room nights, plus regular day guests (each day guest is counted as one-third room night).
