Carbon emissions are an environmental problem due to changes in temperature and ozone depletion. With technology, you will be able to use water and other important resources immediately inside and outside the house. Humans increased the use of water for irrigation and recreation and reduced the supply of water while using water to release carbon. The amount of water used today applies pressure to the water supply. Examining Figure 1, most students use sufficient water each time to release more than 0.40 kg of CO 2.
Environment: An increase in the production capacity of an airline also means more environmental damage - carbon emissions. Older technology aircraft have relatively large environmental damage compared to new technology aircraft. The introduction of carbon taxes in Europe is the first step to put pressure on industry - the use of alternative fuels and new technology aircraft. Airspace and airport capacity: When you arrive at a crowded airport, you need to wait for the turn. The average cost of staying in the air is 12% (reference: IATA). To use the latest technology it is necessary to shorten the separation distance between successive arrivals / departures and to increase the runway capacity, such as a highway exit guideway at an appropriate distance along the runway.
It is environmentally friendly. The use of renewable energy has little emission of greenhouse gases. There is also no effect on the atmosphere due to the emission of carbon dioxide. It will greatly reduce the amount of carbon dioxide (CO 2) damage to the protective layer and will greatly reduce toxic pollution causing disease to the world's population. Economic impact is always one of the main concerns of people and these problems make it impossible for several countries to advance with better, more environmentally friendly and more stable energy options did. However, at the Paris Climate Change Conference (COP 21) held at the end of 2015, renewable energy attracted attention, its strength was demonstrated and its implementation was encouraged.
Adopting sustainable energy is often referred to as "green" because it has a positive impact on the environment. Energy sources like fossil fuels hurt the environment if burned and may cause global warming. The first major international agreement to reduce carbon dioxide emissions and global warming was the "Kyoto Protocol" signed in 1997. Recently major countries of the world held a conference in Paris in 2015, promised to reduce emissions and concentrate on more energy dependent on renewable energy.
