13. When you can buy a new car, choose a gas-saving type. Instead of going to consume 1 gallon of gas that only goes 30km, if your car goes 64km with the same amount of gas consumption and you travel 16,000km per year, you will reduce about 7,000kg CO2 emissions.
14. Reduce the amount of domestic waste. The way is to minimize the use of pre-packaged products or you can use products that are reusable and recyclable. Cutting or recycling each kilogram of waste to the environment will save energy and reduce at least 0.5kg of CO2 emissions.
15. Recycle the refrigerant of the vehicle’s air conditioning system. In the United States, leaks from car air-conditioning systems are the main cause of CFC emissions, a substance that pores the ozone layer and causes the warming effect of the earth.
16. Insulation for walls and roof. This reduces energy costs by 20% to 30% and reduces CO2 emissions from 300 kg to 2500 kg per year.
17. Modernizing the window system. Replace the traditional door with double-layer glass doors, between two layers of glass with argon gas. Using this type of glass door can reduce 2.4 tons of CO2 annually for gas-heated apartments, 3.9 tons for oil heating and 9.8 tons for electric heating.
18. Plant trees and light-colored walls. If you live in hot climates or painted in dark colors if you live in a cold climate. Reducing energy consumption by utilizing shade from the right paint colors can help you reduce up to 2.4 tons of CO2 per year.
19. Install energy efficient equipment and implement energy saving and minimizing measures in the workplace. Establish or join local associations and groups and work with authorities to implement these measures in schools and public buildings
20. Contact local and national environmental authorities to get your opinion on economical and efficient use of energy as well as environmental issues.
