• Can the objective of a trip be achieved in another way, for example through digital communication, and still accomplish a comparable result when it comes to knowledge transfer or building networks? Extra considerations here might include the situations of people in early career phases as well as actual networking needs for people in a given field or international environment.
• Can emissions be reduced by adapting the means of travel or routes? Can air travel be replaced or linked to other stages of the project? Are direct flights available even if they are more expensive?
• Can a quantitative estimate of the environmental impact (especially CO2 emissions) caused by the project’s travel be made?
• When organising conferences: could hybrid or digital formats offer a useful alternative to face-to-face meetings?

General

• Which methodological approaches offer the most potential in limiting resources used and reducing emissions that are harmful to the climate and the environment? 
• Can the design and scaling of the experiment or field trial be better adjusted to the scope required to answer the question, or could a simulation be (partially) used instead? 
• Taking into consideration the uniqueness of the planned research, could available existing data be used to progress the project under more sustainable conditions? 
• Could the complete use of data and/or (if possible) making available of data and/or re-use of available data make new trials and experiments redundant?

Laboratory equipment and non-renewable materials 

• Is it possible to reasonably reduce non-renewables, re-use items or use items made of recycled material? 
• Can providers be found that sell more energy-efficient products? 
• Could purchasing smaller quantities reduce storage costs? Emissions and resource consumption caused by transport must also be taken into account.

Samples 

• Is it possible to draw on existing samples? 
• Is it possible to reasonably reduce the amount of material, re-use the material or make it available to others? 
• Is it possible to store objects in a more climate-friendly and energy-efficient way? For example, can samples be stored at a lower or higher temperature?
   

• Can the computing power for modelling, simulation, evaluation and visualisation be reduced? Are cloud-based solutions an option? Is it possible to use suppliers who provide green electricity?
• Can the energy consumption be reduced by planning the simulations to be carried out even more efficiently?
• When selecting the parameters for a simulation, can you use less energy while maintaining a similar quality of results?
• Could the complete use of data and/or (if possible) making available of data and/or re-use of simulation data be used to reduce energy consumption?
• Can specific statements be made on the environmental impact caused by time-intensive computing simulations (specifically on the level of CO2 emissions)?

• Is it necessary to purchase new equipment if existing or repairable equipment is available (e.g. in a neighbouring working group)? Would the new equipment be more energy-efficient than any existing equipment?
• Before purchasing new equipment, what information is available on its environmental impact and ability to reduce the use of resources and emissions during its production and operation?
• Are there ways to more efficiently use resources and achieve a reduction in emissions by taking into account the service life, repairability and capacity of the new equipment?
• What are the considerations in regard to recycling equipment (old or planned procurement)?
