Introduction
Global warming is the most talked concern in the world now. The developed countries are mainly responsible for the global warming but the countries like Bangladesh are affected more adversely by the global warming for being a coastal country.

The main reason behind global warming is the emission of carbon which reacts negatively with the ozonosphere of the earth. The developed countries like America are emitting a lot of carbon, in the other hand, trees are being cut down and global warming is accelerated due to this imbalance.

All the countries are trying to resolve this global issue, but the carbon emission is increasing day by day. The industries, brick fields, vehicles, electric power plants and so on are emitting carbon every moment in a large amount. The scenario is almost same all over the world. Thus the carbon emission has taken a great concern of the whole world.

In Bangladesh, people use Kupi (Kerosene Lamps) to light at night, who, more than 55%, are not connected with electricity and those who have the electricity also suffer a lot from load-shedding especially in time from evening to midnight. By this time, rural people use these kupies to light their houses using kerosene as fuel which emits a huge amount of carbon.

A survey has been taken in three tribal villages of Bangladesh where more than 90% people are not connected to the national electric grid. The survey took their daily usage of fuel and made an advance calculation on the emission of carbon, the affects of the carbon emission on the nature and its adverse affect on the global warming.

These carbons are mainly emitted in the form of CO2 (Carbon-di-oxide) which is not only harmful to the environment but also harmful to the human health. Especially in case of kupies, here the CO2 are produced in the room where the people live. Additionally, the kupies produce smoke which harms human eyes very badly. Considering all the adverse affects, a proposal is given to introduce a co-operative solar lighting system which will completely remove the carbon emission of the kupies by replacing them with solar lamps powered by the green energy of solar. This co-operative solar powered system will develop the socio-economic life of the rural poor people by reducing the fuel cost and giving them LED solar lights with more luminance, giving more light and more time to search their livelihood. Moreover, the school going children can't study due to lack of adequate clean light at night. This co-operative solar lighting system will give an opportunity to the children so that they can study at night and be educated for the upcoming future.

Environmental Condition:
Let's take a brief look in the Earth's present atmospheric condition. The atmospheric elements show the following percentages:

Fig. 1 Percentage of various elements of earth’s atmosphere [2].

Here, the graph shows that the current concentration of the CO2 in earth’s atmosphere is 0.0387% or 387 ppm [2]. The main sources of this CO2 consists of both the natural sources and man-made sources. The nature produces 220 giga-tones of CO2 each year by the volcanic out-gassing, the combustion of organic matter, the respiration processes of living aerobic organisms, virus microorganisms from fermentation and cellular respiration and many more [2]. The man-made resources produce 13%-40% of the total CO2 emission of the earth every year [2]. These resources include fossil fuels, power generation and...
