Risk Management: Brazilian Environmental Assessments And Unconventional Natural Gas Developments
Natural gas is an energy source among fossil fuels (oil, coal and natural gas)
with less impact on greenhouse gas emissions and can play an important role
in the relevant energy matrix and to the transition to a low carbon economy.
Natural gas can be obtained both from conventional and unconventional
sources. The unconventional gas resources are found in unusual geological
locations and therefore require special extraction technologies (such as
fracking). Unconventional gas may be important to enhance the availability
of natural gas and reducing prices, as it happened in North America. Other
countries have been trying to replicate such success story like Argentina,
China, UK, South Africa, Brazil, among others. However, the experience
of large-scale exploitation of this energy source, notably in the usa, show
potential environmental risks, which could be present in other unconventional
developments as well.
