document helps achieving the objectives set up in the policy.

Guidelines
2.1
Transportation
- Before driving:
o Plan your workload to avoid travelling (e.g. organise meetings the same day, on after the other
rather than on two different days).
o Organise videoconferences when feasible.
o Use public transport as much as possible.
o Walk if distances are under 1 kilometre (unless health condition such as injury, pregnancy,
disability, or heavy load needed).
o Carpool. It is possible to carpool with someone from the council or someone from another
organisation.
o Combustion engine vehicles occupied by only one person are only used as a last resort.
- While driving:
o Drive smoothly, avoiding fast acceleration and sharp braking.
o If you drive a manual vehicle, change up gears to avoid over-revving.
o Reduce short trips (up to +20% fuel consumption when your engine is cold).
o Reduce your speed (up to +10% fuel consumption when driving over the speed limit).
o Don't leave your vehicle idling for long periods.
o Don’t carry unnecessary loads.
o Use your air conditioning wisely (up to +10% fuel consumption when using your air
conditioning).
o Choose a vehicle that's the right size for your needs.
o Check your tyre pressure at least once a month and before long journeys.
- Contact your manager if you wish to have more explanations or training.
2.2
Energy
- When working in the office:
o Turn off electric appliances (lights, heaters, A/C, computers, etc) when not in use.
o Turn off lights, heaters and A/C if you are the last person to leave the premises.
o Set the heater or A/C temperatures wisely.
In an indoor environment, the following temperature ranges should provide thermal comfort
for most people:
SUMMER
WINTER
Sedentary work
19-24°C
18-22°C
Physical work
16-21°C
16-19°C

Set the heater or A/C temperatures inside the thermal comfort range. The temperatures
should preferably be set on the highest part of the range in summer (24°C) and the lowest
part of the range in winter (18°C).
o Use the blinds provided to keep the warm in in winter and keep the heat out in summer (shut
the blinds when necessary).
o Save water (do not leave the tap running for nothing, turn the dishwasher ON only when full,
use the half flush when possible).
- Contact your manager if you wish to have more explanations or training.
2.3
Information Technology – Prints
- Before printing:
o Make sure you need to print the document.
o Print double-sided if possible.
o Print in black and white if possible.
- Other:
o Create and maintain a positive digital footprint by being aware of the greenhouse gas
emissions coming from the Internet and the emails (electricity used by devices, servers etc).
A typical email (no pictures) is responsible for 4g of CO2 and 50g of CO2 if the email has a
picture attached1.
- Contact your manager if you wish to have more explanations or training.
2.4
Solid waste
- Use the bins provided (compost, recycle and refuse).
- Contact your manager if you wish to have more explanations or training.
