Today aviation is a service not just for the wealthy. It is accessible to the vast
majority of the global population and serves a varied and valuable contribution to the
global societal fabric from connecting friends and families, populating ideas and
cultural sharing as well as enabling vital business through physical interaction and
efficient cargo movement. Modern transport sector is developing constantly. The world
volume of aircraft transportation increases on 4–5 % annually. Transport
predominantly relies on a single fossil resource, petroleum that supplies 95 % of the
total energy used by world transport. Along with the situation in exhausting of crudeoil
deposits, the state of environment causes a special concern. According to the report
by Intergovernmental Panel on Climate Change, transport is responsible for 23 % of
world energy-related greenhouse gases emissions with about 17 % coming from road
vehicles and 2 % from aviation. Over the past decade, transport‘s and aviation‘s in
particular, greenhouse gases emissions have increased at a faster rate than any other
energy using sector. And according to some forecasts air traffic will be responsible for
about 20 % of harmful emissions by 2020.
