The Green House Gases (GHG) have increased considerably in comparison with those of the pre-industrial time (year 1750). Indicatively, since 1750, CO2 in the atmosphere has increased by 41% while methane has increased by a shocking 160%.It should be noted that each gas contributes at a different extent to the Greenhouse.

The increase in the amount of greenhouse gasses (mainly by human factors) leads to the overheating of Earth, with important consequences to the ecosystem and therefore the life of us, people. The problem is that the increase in CO2 concentration is increasing as time passes. Indicatively, in 1750 the concentration of CO2 was 280ppm (parts per million). In 1973 (223 years) this amount had increased by 50ppm, while from 1973 to 2006 (33 years) it increased by another 50ppm!

"Mankind is changing the climate," Professor Sir David King, Britain's chief scientific adviser told the BBC earlier this year.Another 100 ppm increase in CO2 concentration could boost global temperatures an average of two to four or five degrees higher."Three degrees Celsius higher and we don't know if ecosystems can cope. At four degrees, we'll be in big trouble," says Andreas Hamann, a forestry expert at the University of Alberta, Canada.

The EU, in 2009, took measures to encounter the greenhouse effect, ensure security of energy supply and increase the energy efficiency. These measures were called 20-20-20 (20% reduction of CO2 emissions, 20% of energy consumption expected to come from renewable energy sources (RES) and 20%, reduction in primary energy use has to be achieved by improving energy efficiency) until 2020, in comparison with the relevant data from 1990.

The way to meet these energy and climate targets is given by renewable heating and cooling (RHC) technologies: solar thermal, biomass, geothermal, district heating & cooling (DHC), heat pumps, hybrid systems and thermal energy storage.However, many people consider these measures very conservative.

As a result, new and more ambitious goals have been set for 2030: 40% reduction of GHG emissions, 27% increase in RES (renewable energy sources) and 27% reduction in primary energy use by improving energy efficiency.

The EU decided that these percentages should concern each member separately. But, these goals are simply indications and are not mandatory for every member.

According to WWF and other environmental organizations, the new targets are inadequate to address the phenomenon of climate change.

Greece is one of the countries that are worst affected by climate change (forest fires, heat waves, drought, decrease in water resources, agriculture, touristm, etc.). Unfortunately, while the government says it will fight this problem, not much is done in this direction.

Additionally, while the Greek government states that it supports the mandatory application of the above policies, it ended up voting for more "loose" policies.
At the same time, the government voted for the construction of the new energy production factory, based on the very polluting lignite instead of pushing development using RES. Lignite power generation in Greece is the largest single source of GHG emissions accounting for ~35%.

The financial crises in Greece, but also the general economic downturn in many Europe countries has been used as an important argument in lowering the policies for the protection of the environment, which, among others, will be a burden itself against the efforts to reduce GHG emissions.

As long as global warming appears to be a future risk, and is not expressed convincingly as a problem in our everyday lives, there is a serious likelihood that it will be underestimated. If that happens, it might be too late for the consequences to be encountered properly.

In this very important environmental problem, the solution is awareness, and Tunza Eco-generation is an important effort in this.
