By forcing everyone to quarantine, fighting the coronavirus has its positive side and brought back images that entire generations had never seen before. As an example, the murky waters of the Venice canals in Italy have become clear because of the tourism ban. Even fish have been seen again. In Brazil, the effects are similar. An application called carbonZ (www.carbonzapp.com.br), which performs calculation of carbon footprint (CO2 emission into the atmosphere) of companies, people and events, shows that shortly after the first week of trade closure and abrupt fall in the use of means of transport, there was a 65% reduction in atmospheric emissions in Greater São Paulo. "We are talking about the reduction of 107 kg per person", says Gabriel Estevam Domingos, director of Research and Development of Grupo Ambipar, holder of the carbonZ application assets. If the figures are maintained, it will be a reduction of 1.3 million tons of CO2 per month, in the city of São Paulo alone, which has 12 million inhabitants. "That’s proportional to 7.9 million trees."
The application works based on data entered by more than 4 thousand registered customers. Free of charge, it can be downloaded on mobile phone and has served as a tool for companies to implement programs to neutralize carbon emissions. The calculations allow companies to know how many trees must be planted to neutralize the atmospheric impact generated by their activities. The carbonZ commits itself to planting (at the cost of R $ 45 per unit), enabling the tracking of planted seedlings. "The first company to use the app was Bayer. We helped the multinational plant 3,000 seedlings at the time of the water crisis," Domingos said.
