Cycling has relevance to a number of environmental issues:

• Climate change: no emissions in use; fewer emissions than cars in their production.
• Clean air: no emissions.
• Noise: no noise.
• Traffic congestion: more cyclces on the road mean fewer cars on the road, and therefore less congestion.
• Urban planning: Planning for cycleways makes it easier to reduce car use.
• Waste dispoal: bikes are less costly to dispose of, in both physical space, and in their recycling.
• Recreation: recreational cyclists seek access to "the great outdoors".
