Mobility and climate change
How far can I get on half a gram of CO 2 ? The participants find out how far they can travel by car, coach, long- distance train and plane if each vehicle produces the same amount of greenhouse gas emissions. They each "travel" until they have emitted a certain quantity of climate-damaging greenhouse gases. The exercise teaches participants about the greenhouse gas emissions of different modes of transport and encourages them to reflect on their own mobility behaviour. At the end of the exercise, participants can discuss the advantages and disadvantages of the different modes of transport. If there is enough time, workshop leaders can provide more information on the subject of mobility.

Time required 20 to 30 minutes
Method
Interactive game requiring lots of space
• Four tape measures or similar (cord, etc.) 1.96m, 5.20m, 12.20m and 19.23m in length • 8 pieces of cardboard, two for each mode of transport, cord or string • Creation of eight cardboard signs (two planes, two cars, two trains, two coaches) which participants hang around their neck • Creation of measuring tapes or similar with the following lengths 1,2 , – Plane (short-distance flight of up to 1500km): 1.96m – Car (mid-size, petrol, 1 person): 2.60m
Materials
Preparation
– Train: 12.20m – Coach: 19.23m
Opening The participants start by naming the types of transport that can be used to travel from one city to another. It’s a good idea to pick two cities they can travel between either by train, coach, car or plane. Once they have named the four modes of transport car, coach, train and plane, eight volunteers are selected. The workshop leader then distributes the eight signs amongst the volunteers and assigns two appropriately labelled signs to each mode of transport.
1 The distances are based on: UK Department for Business, Energy & Industrial Strategy. Greenhouse gas reporting: conversion fac - tors 2019.

However, depending on how trains are powered, e.g. whether by electricity − and depending on how this is generated − or whether by diesel, these levels differ from country to country. Vehicle occupancy, i.e. how many people travel in a train, plane or coach, also affects the calculation. The examples given here are based on data and average values from the UK. Nevertheless, they are a useful point of reference. The emission of greenhouse gases, so-called CO 2 equivalents, is measured. Cf.
