The Declaration of the Third Ministerial Conference on Environment and Health (June 1999) states: We are determined at international and national levels to effectively reduce the significant adverse effects and barriers to community development created by transport-related air, soil and water pollution, accidents and noise, greenhouse gases emissions and damaging of forests and to increase the health benefits of physically active transport modes, notably cycling and walking (including to and from means of public transport). Actions taken in the relevant fora to achieve these different aims should be consistent, notably concerning the reduction of greenhouse gases and other health-damaging emissions.
