GREENHOUSE GAS EMISSIONS AS A GLOBAL PROBLEM OF NOWADAYS

Greenhouse gases (GHGs) warm the Earth by absorbing energy and slowing the rate at which the energy escapes to space; they act like a blanket insulating the Earth. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The primary sources of GHGs emissions are: electricity production, transportation, industry, commercial and residential, land use and forestry, and agriculture. From year to year, emissions can rise and fall due to changes in the economy, the price of fuel, and other factors. How will economic and social developments drive environmental change to 2030? If we will not seriously deal with GHGs emissions we risk irreversibly damaging the environment and the natural resource base needed to support economic growth and well-being. The "Climate Action and Renewable Energy" package adopted by the Council on 6 April 2009 underlined the objective of limiting the rise in global average temperature to no more than two degrees Celsius above pre-industrial level. To achieve this goal Member States agreed to reduce total EU GHGs emissions by 20 % compared to 1990 by 2020. Is it realistic? The aim of our article is to create a mathematical model based on Markov chain to describe changes in emissions development.
