Climate change is one of the greatest threats that humanity faces. The tourism industry and moreover the hotel industry, should be the pioneers in efforts towards global agreement for the reduction of greenhouse gas emissions.

The commitments of Greece and the rest EU countries adopted a comprehensive package of measures to reduce emissions. The objectives of these measures are to reduce greenhouse gas emissions at least 20% by 2020 (compared with levels in 1990), to increase the market share of renewable energy resources at 20% and to reduce total energy consumption by 20% (compared to provisions). In order to promote the use of renewable energy resources, it was decided that the 10% of transport fuels have to come from biofuels, electricity or hydrogen.
