Lack of investment in safe walking and cycling infrastructure is contributing to the deaths of millions of people and overlooking a great opportunity to contribute to the fight against climate change, a new UN Environment report says. In Global Outlook on Walking and Cycling, UN Environment calls on countries to invest at least 20 per cent of their transport budgets in walking and cycling infrastructure to save lives, reverse pollution and reduce carbon emissions, which are rising at over ten per cent a year. The report surveyed the progress towards safer walking and cycling infrastructure in 20 low- to middle-income countries across Africa, Asia and Latin America, where compared with high-income countries, twice as many more people die in road traffic accidents.
