What is Laboratory Efficiency and Assessment Framework (LEAF)?

LEAF is a green initiative developed by University College London (UCL) to improve the sustainability and efficiency of laboratories, technical workspaces including workshops, studios and galleries.

LEAF contains actions which lab users can take to save plastics, water, energy and other resources. By taking part in the programme, laboratories and other workspaces can 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.

A key feature of LEAF is that it allows participants to estimate what impact their changes have made (both in financial and carbon terms) with user-friendly calculators.

LEAF is supported by the UKRN (UK reproducibility network). This is in recognition that high-quality research is sustainable research – Ensuring that studies are reproducible and that we make use of the data we generate is a sustainability challenge as well as one for science. UKRN provides an annual review of the actions within LEAF which relate to research quality.

LEAF is also supported by the National Technician Development Centre (NTDC), in recognition that the application of sustainable lab practices improves career development and visibility for technical staff.
