Greenhouse Gases• Greenhouse gases cause global
warming • Notably:
– carbon dioxide – ~80% – methane – nitrous oxide– fluorinated gases
• Greenhouse gases trap the sun's rays within the Earth's atmosphere
• Sources of greenhouse gases:– energy production, – deforestation, – agriculture – waste disposal

Changes in Ecosystems
• Adélie penguins on Antarctica: – from 32,000 breeding pairs to 11,000 in
30 years.
• Some butterflies, foxes, and alpine plants – have moved farther north or to higher,
cooler areas.
• Polar bears: since the mid-1980s, – polar bears have gotten considerably
skinnier, with less ice on which to live and fish for food
– If sea ice disappears, the polar bears may as well.
• Some diseases will spread, such as malaria carried by mosquitoes

Reducing energy usage and wastage
• Laboratories consume more energy per square foot, often x5 as much compared with non-laboratory buildings such as offices.
• Clean-rooms: consumption can be is 10-100-times higher.
![Page 45: 1 The Next Frontier for Laboratories - Going Green Joseph Lopez Associate Professor and Head, Dept. of Biomedical Sciences, MAHSA University Kuala Lumpur](https://reader030.vdocuments.us/reader030/viewer/2022032723/56649cff5503460f949cfde2/html5/thumbnails/45.jpg)
45
Lighting in Labs
• Lighting in laboratories is up to x2 that of a typical office space.
• Lighting energy use typically accounts for 8% to 25% of total electricity use
• Use LED lighting

Good Practices• Daily “end of day” lab and office walk-throughs - to
manually close lights equipment, instruments.
• Chiller/heat temperature and humidity controls - adjust according to the seasonal demands.
• Analytical equipment and processes: shut down when not in use
• Regular equipment maintenance
• Consolidate equipment and instruments of different units of the laboratory where feasible.

Reduction
• Reduction of test numbers – audits of tests requested and their
usefulness to identity unnecessary requests
• Reduction in the use of collection tubes
• Reuse of specimen collection bags • Paper management to reduce usage• Waste reduction • Water Usage

Paper Usage
Reduce, Reuse, Recycle • Reduce:
– introduction of paperless systems; – Introduction of non-paper options
where possible
• Reuse: Print and photocopy double-sided
• Recycle
• Paper usage audits

Clean Water
• Deionised water – Consider resin technologies instead of
Reverse Osmosis systems, since the latter are wasteful of water and energy.
• Perform an audit of water usage and look for ways to reduce water usage

Environmentally-friendly buildings
• The Leadership in Energy and Environmental Design (LEED) - an internationally recognized green building certification system
• The LEED standard has been adopted in the USA as the industry standard of measurement for green buildings
• Such buildings: – use environmentally preferable materials – reuse building materials – Achieve energy reduction through
modifications and operational changes – have improved water-usage efficiency and
waste handling

Advocacy - Influencing others
• Staff: – engage in carbon-offsetting
activities
• Vendors: – Contractual conditions on vendors to be more
environmentally friendly in dealings with the laboratory
– to supply instruments that consume less energy, water and produce less waste.
– powered reagents requiring reconstitution - leaves a smaller carbon footprint when transported

What we need to do
• Make a commitment
• Reduce disposables: – Wash and reuse – use less plastics
• Reduce energy consumption
• Buy: – powdered reagents reconstituted at point of usage – chemicals in reusable/returnable containers– Take back packaging– Instruments that consume less energy, water
• Remember: Cost savings in good environmental practices
