Private-sector initiatives have generated some results. For example, ASOCANA, the association of sugar cane producers of the Cauca Valley, increased the amount of green cut of sugarcane harvested without burning from 23% to 39% between 2006 and 2012. In a city of 7.6 million people, it accounts for more than 1.5 million, or 74%, of public transit trips in the city.
