How does transportation impact climate?
Why is business travel important?
What effect has COVID-19 had on business travel?
As a consequence of global lockdown and stay-at-home measures, mobility and its associated emissions declined by an unprecedented amount in early 2020. Global business travel spending fell by roughly 61% in 2020 over the previous year due to the pandemic. (5) Transport demand is rebounding since 2021, both passenger and cargo. Global aviation passenger numbers are expected to return to 2019 levels in 2023 and demand is projected to grow over the next decades. (6)
Why is this a key issue for the aid sector?
Business travel is one of the greatest contributors to an organisations’ carbon footprint. This is especially true for the aid sector, which provides assistance worldwide. Meetings, training, missions, evacuations, home leave – there are numerous reasons for travelling.
What are the main families of solutions?
In addition to reducing the number of trips, several other types of solutions exist such as fuel efficiency, alternative fuels and alternative modes of transport.
Some key principles to consider
Reducing and adapting one’s professional travel behaviour is a critical step in mitigating the climate footprint of an organisation. However, these changes must not compromise the mission of the aid sector of assisting individuals worldwide. Business travel solutions must therefore be carefully selected and adapted to the various contexts, geography, accessibility, security or reasons for travel.
Is it easy to implement?
Business travel solutions are relatively easy to implement, without contravening the aid organisations’ primary objectives. They provide substantial emission reduction, they have an immediate effect, they require minimal intervention, they are easily measurable and they have a high symbolic value. According to a 2021 study, 83% of travellers worldwide believe that sustainable travel is important. (7)
The COVID-19 crisis has altered business practices, especially travel. Organisations learned to adapt. New tools were adopted as alternatives, such as videoconferencing. Despite the success many organisations experienced through a year of essential-only travel, some business leaders also realized the value of face-to-face interaction. As lockdown measures are disappearing, the standardisation of these new business travel practices is on the table, to reduce an organisation’s climate footprint but also to reduce costs and improve staff well-being.

The rebound effect
Sobriety and alternative sources of energy are the primary and main levers to significantly reduce carbon emissions globally.
When improvements in energy efficiency contribute to the reduction of energy consumption, this leads to reduction of usage cost, and therefore to more consumption. For example, more efficient engines that use less kerosene can lead to a reduction in the price of air travel, which in turn can lead to an increase in passenger demand and therefore in the number of flights worldwide, thus emissions.

# 1 Online meetings
Prioritise travel-free meetings and use video conferencing as much as possible for remote meetings. Discover more
#2 Airline choice
Favour the most eco-responsible ones, such as the most fuel-efficient ones or the ones using sustainable alternative fuels.
#3 Train on short-hauls
Prioritise ground travel, train especially, for all short-haul trips.
#4 No stop-overs
Take direct, non-stop flights to avoid detour emissions and high emissions during takeoff and landing.
#5 Economy class tickets only
Flying business or first class produces much more GHG emissions per passenger. Discover more
#6 Combined business / leisure trips
Allow staff to extend a business trip with a personal stay to reduce all professional and personal emissions of staff.
#7 Loyalty programs
Donate all benefits received through loyalty programs to climate friendly projects.
#8 Less-carbon intensive vehicles
Buy, rent and use lighter, fuel efficient, bioethanol or electric cars.
An ambitious travel policy is one of the cornerstones of an effective climate strategy at an organisation’s level. It sets the rules and provides a clear and common framework for all staff. It allows for bold climate actions and best individual practices to be generalised across the entire organisation, thus scaling up the impact.
Specific tools can be developed or adjusted to support the implementation of the policy, such as a travel decision & booking tool.
Innovative financial means can be introduced to support a balanced budget, such as an internal carbon taxthat can be reinvested in green practices.
Behavioural incentives are essential. Awareness raising posters are useful tools to inform and engage the staff.
