Sustainable travel specialist Trees4Travel has joined forces with analytics firm Cirium to provide corporate clients with additional data to measure air travel emissions.

The partnership will leverage Cirium¡¯s recently launched Emerald Sky carbon calculator to provide ¡®accurate¡¯ insights into air travel emissions, both during the booking process and for post-travel ESG reporting, according to the companies.

The Emerald Sky calculator utilises Cirium¡¯s flight analytics to ¡®precisely calculate¡¯ fuel consumption and an aircraft¡¯s CO2?output, the companies said.

Its calculation methodology is based on fuel burn rather than flying distance estimates and considers factors such as aircraft type and engine configuration, age, flight duration (both physical taxi and airtime) and passenger and cargo load, according to the companies.

¡°This precision in measuring aircraft CO2 emissions offers stakeholders valuable insights for developing far more effective CO2 reduction strategies,¡± the companies said in the statement.

Cirium CEO Jeremy Bowen added that the company has ¡°significantly invested¡± in the development of Emerald Sky, which leverages schedule information from more than 900 airlines, is updated 280,000 times daily ¡°and [is] fully auditable¡±, he said.

Emerald Sky will be offered to Trees4Travel corporate customers along with the company¡¯s existing carbon calculators, which Trees4Travel CEO Nico Nicholas said ¡°allows us to offer a whole suite of ultra-sophisticated tools to measure emissions¡±.

¡°Our collaboration takes carbon management to another level¡­ [and] is an important ¡®string to our bow¡¯ for both us and our TMC partners,¡± he added.

In addition to the new Cirium partnership,?Trees4Travel also offers emissions methodologies from the UK Department for Environment, Food & Rural Affairs (DEFRA), Google¡¯s Travel Impact Model and Cornell University¡¯s hotel benchmarking index.
