Sustainable UCL


Offset Your Travel

Sometimes travel is unavoidable so we are currently developing a UCL-wide carbon offsetting scheme. In the meantime we suggest that staff plant trees in a UCL Grove with Trees for Life. We can testify that this programme will lead to a verifiable reduction in carbon emissions and will improve UK biodiversity by planting native species, whilst working in partnership with local communities.

Trees for Life plant native trees in the Scottish Highlands – helping to restore the Caledonian Forest. We have developed a UCL grove with Trees for Life for UCL staff and students to offset their carbon emissions.

To compensate for your carbon emissions using the UCL Grove follow these steps:


  1. Find out the carbon emissions from your trip: When you book your trip through the Clarity travel booking system the carbon emissions associated with your trip will be displayed. If you need to calculate emissions yourself we recommend using this carbon emissions calculator. 

  2. Find out how many trees to plant: Once you have your emissions in tonnes, calculate the number of trees needed to offset the emissions. To do so, use this simple formula: Multiply the number of tonnes of CO2 by 4 to find out how many trees you need to plant. 1 tree fixes 0.25 tonnes of carbon over 100 years. If you want to offset your emissions in a shorter time frame, use this Excel calculator to work out how many trees you need to plant as well as the cost. 
  3. Get planting! Once you know how many trees you need to plant to offset your carbon emissions, add them to The UCL Grove by clicking here. It is only £6 per tree!

If your budget is tight, plant fewer trees! If you wish, contribute more! Add as many trees as you can afford!

Trees are planted by Trees for Life in batches in Spring and Autumn. The “Grove” refers to the trees you contribute rather than a specific physical grove on a hillside.

However, all trees will be planted in the Scottish Highlands either in Glen Affric or in Trees for Life’s Dundreggan Estate. Trees for Life runs a volunteers programme – some of your trees will be planted by volunteers and some by professionals.
