Down to earth

Travel is an essential part of the jobs of many UN staff, yet it is a major source of GHG emissions. In fact, in 2017 it was responsible for 56% of the UN’s greenhouse gas emissions - 42% from air travel and 14% from other forms of travel (e.g. UN-owned vehicles, commuting, etc.).

The challenge facing all UN staff and organizations is how to reduce our travel-related carbon-footprint without reducing the effectiveness of our work.

There are a number of ways to do this including:

  • Arranging meetings in locations requiring minimum travel by delegates
  • Ensuring no more than two staff from one organization travel to the same meeting
  • Using local staff rather than travelling yourself
  • Planning trips carefully so as to reduce the number of flights required
  • Where possible, taking the train instead of the plane
  • When travelling by car, providing lifts to colleagues, to reduce the number of vehicles going from A to B

It’s not just about cutting carbon emissions, a more sustainable approach to travel planning also helps to cut costs and reduce stress for staff.

A number of UN organizations have already introduced policies to help reduce the costs and carbon associated with travel. You can see some examples on the case studies page.

We’re keen to hear how you have cut your travel-related carbon emissions. Please feel free to share your tips below. Or to suggest measures the UN could introduce to make our transport more efficient.

Did You Know?

  • Travel is responsible for approximately 56% of the 2017 UN’s climate footprint.
  • Choosing economy instead of business class travel reduces travel emissions by up to 50%
  • The emissions from a return business-class trip between New York and Beijing are equivalent to 3 tonnes of CO2, which is 54% of the average persons emissions per year (Sustainable Travel in the UN, 2010)
  • If just 1 million people replaced an 8km car trip with a bike ride once a week, CO2 emissions would be reduced by nearly 100 000 tonnes a year (Green Passport, 2010)

Sustainable Travel in the UN (2010) provides guidance on what UN organizations can do to improve the sustainability of their travel. Travel is responsible for approximately 50% of the United Nations’ climate footprint and represents a major cost to UN - over 1 US$ billion per year for the collective UN family. At the same time, travel is an essential means by which the UN delivers its mandate, and often cannot be avoided.

ICAO Planetary Priorities (2009) is a journal containing articles and insights discussing the addressal of emissions from international aviation.

Towards a Low Carbon Travel & Tourism Sector (2009) examines the ways in which the Travel & ToTourism sector could reduce its impact on climate change. Current findings indicate that the Travel &  Tourism sector's contribution to GHG is at 5% (global anthropogenic emissions).
