 Formic acid is a naturally occurring component of the atmosphere primarily due to forest emissions.In 2009, the worldwide capacity for producing formic acid was 720,000 tonnes per year, roughly equally divided between Europe (350,000, mainly in Germany) and Asia (370,000, mainly in China) while production was below 1000 tonnes per year in all other continents.It is commercially available in solutions of various concentrations between 85 and 99 w/w %.
