If countries decide agreements, the influence and importance of cities cannot be underestimated. Every second, world cities populations increased by two people. By 2050, the target date for climate talks, will have increased from 3.9 billion to 6.4 billion. How cities engage in the struggle to slow, precent, reverse climate warming is essential.

But it also shows that cities can have impact on pollution, and the efforts to reverse worldwide trends. That so many of us live in cities, all the more reason why it is important that we make efforts to decrease our footprint. And there are few efforts as substantial and proven as riding a bike every day, for every journey under four kilometres.
