How a global engineering firm drives sustainable travel decisions through employee engagement

EngineeringFirm

A leading global engineering firm with over 30,000 employees has sustainability embedded as a core business value. Among its many targets is an ambitious goal to reduce business travel emissions.

To get there, it needed its travellers to make more sustainable decisions.

Company Global engineering firm
Employees 30,000+
Travelling employees 10,000+
Goal Reduce business travel emissions
The challenge

An incomplete picture, and messages travellers ignored

The firm’s emissions data came mainly from its Travel Management Company, so it wasn’t capturing many of the sustainable choices travellers were already making.

Internal sustainability communication was generic and lacked meaningful engagement. A better way was needed to reach 10,000+ travelling employees and drive behavioural change.

The solution

Integrated data feeds

Thrust Carbon connected both travel and expense data sources to Thrust Calculator, giving the firm a complete picture of its travel emissions and a better understanding of employee travel behaviour.

The integration captured roughly 400,000 yearly journeys on regional public transport, a sustainable choice previously omitted from reporting.

Hyper-personalised email summaries

Quarterly emissions summaries go directly to 10,000+ travelling employees, each with sustainability suggestions tailored to the individual’s travel patterns.

Comparisons against teams and business units create healthy competition and awareness of collective progress towards sustainability targets.
