Sustainable UCL


LEAF - Laboratory Efficiency Assessment Framework

LEAF is a standard set by UCL to improve the sustainability and efficiency of laboratories. Join the 85 global institutions already taking part and help address the climate and ecological emergencies through your science.

What is LEAF?

Laboratory-based research is essential for advancing society but it is also extremely energy and resource intensive. It’s estimated that laboratories are responsible for around 2% of global plastic waste and use 3-10 times more energy per meter squared than a typical office.

By joining the LEAF programme, laboratories reduce their carbon emissions and create an environment that supports research quality.

Laboratories are awarded either a Bronze, Silver, or Gold level depending on how many sustainability actions they take.

The LEAF programme comprises four elements:

  1. The Framework: An online tool that guides users through sustainability actions to save plastics, water, energy and other resources in their laboratory.
  2. Online calculators: To help measure financial and carbon impact. You can estimate how sustainable your lab is now and track improvements.
  3. Toolkit and Resources: From guides to sustainable lab equipment and consumables to induction and exit procedures. 
  4. User Engagement & Training: We offer each institution a tailored workshop to engage laboratory staff and students on sustainable science, and to introduce LEAF.
