Here is why cities around the world should build 2 km high quality, segregated cycling lane per 1000 inhabitants (thread β¬) π²β
To avert catastrophic climate change and limit warming to 1.5Β°C we need to reduce carbon emissions from transport drastically. In fact transport is the problem child of carbon emissions. In many countries transport
emissions are rising while all other emissions are falling. 2/n

Cycling π² is (almost) zero emission already, together with walking πΆββοΈπΆββοΈand public transport π it can be a great contributor to lower carbon emissions π³. 3/n

However, there is a big barrier to increasing cycling and getting more people to use their bikes: road safety. Cyclist fatalities have been decreasing eight times more slowly than deaths of motor vehicle occupants. 4/n

But how are countries like Denmark π©π° or the Netherlands π³π± succeeding? The two countries have famously high bicycle mode shares π²π²π²and decades of experience providing great infrastructure for cyclists. π²π²π³ 5/n
Letβs take the best as example: The Netherlands π³π±.
Some 35,000 km of cycle-track has been physically segregated from motor traffic, equal to 1/4 of the country's entire 140,000 km road network; this enables an incredible high cycling modal share. 6/n

π²π³Quality counts: The backbone is a country-wide
network of segregated, high-quality cycling lanes with a minimum width of 2.5m per direction, clear signage,
weather resilient design, that provides continuous
connections, etc. Smaller streets are designed with low speeds. 7/n

To achieve a quality network π²such as the Netherlandβs, governments should build roughly 2km of segregated high quality cycling lanes per 1000 inhabitants. This cycling quality indicator obviously does depend on local topography and population density. 8/n
2km / 1000 inh. equals 16 000 000 km worldwide. Do you think this is exaggerated ? Figures for road networks vary widely, the 64 million km from Wikipedia seem reasonable. Why should the
most sustainable mode of transport (cycling π²) get less? 9/n

π² Further considerations:
β’ Large cities can make a "development contribution"
to the hinterland for long-distance commuting, and
to areas where city dwellers relax.
β’ Pursue multi-year planning
β’ No new road or rehabilitation without high quality cycling infrastructure. 10/n
