Laboratory Efficiency Assessment Framework

Committed to reducing the environmental impact of all our activities.

The University of Warwick participates in the LEAF (Laboratory Efficiency Assessment Framework) Link opens in a new windowinitiative, designed by UCL that facilitates and drives improvements in laboratory efficiency.

LEAF is open to academic and research laboratories, including research or teaching facilities.

Laboratory activities are one of the most intensive in terms of carbon impact of the University. This is due to the energy intensity of laboratory equipment, and the embodied carbon of chemicals and equipment, especially when compared to the more typical academic spaces.

We work within the UCL online tool (portal) to capture evidence, and audit the Framework.

The use of the LEAF online calculators, to quantify actions, where plausible, is encouraged for groups working at a Silver or Gold level.

LEAF

LEAF is a two step process, using self assessment and peer-review to consider a range of criteria across three levels, including: waste, people, chemical handling, water, ventilation and research standards.

The time expectation is that Step 1 would take at maximum one hour of desk based work, and Step 2 take at maximum one hour of in-person auditing.

Step 1 - After registering on the platform, laboratories under take a self-assessment, which will show the group to what level they are working: bronze, silver or gold.

  • Laboratories are encouraged to initially review within Term 1, then implement their continually improvements within Term 2.
  • Laboratories are encouraged to read and assess the criteria at all levels to determine their inital level.

Step 2 - At the End of Term 2, there will be a Call for Submissions. Laboratories will need to submit the evidence of the self assessment to the Auditing team. The Auditing team will contact each laboratory to organise a suitable time to visit and review the submission in-person.

LEAF Auditors

Our LEAF Auditors are our Champions within the space, all have participated in the process for multiple years, and have experience that can support colleagues with submissions. They are:

  • SLS / WMS: Lesley Ward, Jeanette Selby, Muriel Erent, Nicole Pereira
  • Chemistry: Anish Mistry, Jo Drozd, Nafiz Biswas
  • RTPs: Chris Waldron, Ben Breeze, Cledi Zampronio
Volunteer with us to be a LEAF Auditor

We are looking for staff volunteers to support the auditing process for the LEAF scheme. This is a valuable opportunity to get involved in improving sustainability across our laboratories.

As a volunteer auditor, you will receive training and gain insight into how different labs are embedding sustainable practices. Your contribution will help ensure the credibility of the scheme and drive positive environmental change across the university. No prior experience is required, and staff from all departments are welcome to take part.

Estates Support

The central Sustainability team administer LEAF, and act as a point of contact for all Laboratories.

  • For support outside of the standard auditing calendar
  • For support on grant submissions, and information about what the University is doing

Please contact:

  • Sam Shaw - Estates Sustainability Officer

Requirements

Funding Requirement RE: Concordat for the environmental sustainability of research and innovation practice

There is Sustainable Research Practice Guidance to provide guidance, direction, information and advice to help Researchers identify their responsibilities and to raise awareness of risks and expectations when designing and conducting research.

Bronze Award
LEAF bronze aims to be accessible for all labs. However it also has the most categories for initial compliance, in order to set the groundwork and ebbed sustainability within the lab space. The requirements are listed here with suggestions from our current labs as to how to achieve the Bronze award.
LEAF Requirement - Bronze Award
Implementation Suggestions
The lab has an induction procedure in place for all new arrivals, explaining the sustainable practices to take.  
The lab has a system in place to clear or track materials left by departing staff.  
Either the lab has a nominated person to drive sustainability forward or a group of people that meet to address sustainability.

There are departmental Green Action Teams.

The Staff & PGR Green Champions Network is home to the LEAF network at Warwick.

They should be a lab member within the online LEAF platform. Any members of a lab can sign up to the LEAF platform at the top of the page.
Sustainability has been added as a standing agenda item into regular meetings and/or relevant networks (e.g. Health & Safety)  
Purchasing of consumables is completed through central procurement Purchasing consumables through OPERA catalogues ensures the suppliers are competitive and compliant.
Energy and materials consumption have been considered during the purchase of new materials. When tendering with central procurement for new equipment the energy efficiency should be requested as part of the sustainability weighting.
All samples and chemical containers have legible labels, or there is a system in place to ensure that going forward all samples will be consistently labelled.

Manufacturer packaging is preferable.

LabCup is being used by Health and Safety for COSHH compliance.

The lab has a system in place for sharing chemicals between users within the lab group.

LabCup is being used by Health and Safety for COSHH compliance.

LabCup has a functionality that offers chemical sharing. Ensure this is available to you.

Fume cupboards and safety cabinets possess signage encouraging good practice.

Laboratory know if the Fume Cupboard is VAV or CAV

Sashes lowered when not in use, with visual reminders.

Not used for storage

Unused taps removed - contact: estates.servicedesk@warwick.ac.uk

Any issues that estates must address have been reported. This includes ventilation, room pressure, water leaks, heating & cooling, and etc. Contact: estates.servicedesk@warwick.ac.uk
The lab possesses required waste bins (possibly clinical, glass/sharps, hazardous etc.), as well as recycling/general waste bins with appropriate and clear signage.  
Ideally users should request life-cycle assessments (LCAs), though should be prepared for vendors to not have these available. This is most pertinent when tendering for equipment over £10,000, and should be included within Tenders.
Heat sources on cold storage equipment are not blocked, and any filters are cleaned regularly. This could also be applied to data banks or in-lab servers that require ventilation. All units should be at least 3" or 7 cm from a wall.
Cold storage, ovens, or incubators are only operated when they are as full as possible. Highest energy intensive equipment should be run efficiently, considering the total load capacity, run time, and minimising the start up / close down sequencing without increasing the standby time.
There is a system in place to ensure equipment and lights are turned off when they are not needed.

RAG stickers may be available from LEAF Auditors, or designs can be locally printed.

Stickering is recommended for use on all small equipment.

Consider if equipment is suitable, including if sequencing where time would not be lost by turning off after use.

Stickers are recommended that detail the start up / close down time.

Computer monitor brightness settings and computer time-to-sleep have both been minimised.  
The lab (or relevant group) has taken part in 1 team activity of sorts over the course of the year, or one is imminently planned. This could include the Green Champion bi-monthly lunches, or Biodiversity surveys
Common protocols and methods are centrally shared and available to all lab members.

Use of SharePoint is suggested.

QR codes can be used to provide point of requirement documentation.

Computer monitor brightness settings and computer time-to-sleep have both been minimised.  
The lab has had its pipettes, scales, and any such equipment calibrated in the past year, or has them scheduled to be done. This applies to all equipment, having planned preventative maintenance, or annual servicing / calibration in place for all equipment.
