A generic term which embraces the design, implementation, operation and management of environment-friendly transport modes. As a rule, the environmental impact of a means of transport (especially its greenhouse gas emissions) is the first criterion for determining whether it is "soft" or not. However, many other aspects may be included in the definition, such as safety, noise levels and the impact on the urban landscape. Walking, cycling, tramways and electric vehicles are frequently cited as examples of soft mobility. Also referred to as ecomobility and sustainable mobility.
