Recently, the concern for global environmental issues has risen all over the world. The increment in concentration of the heat-trapping greenhouse gases that causes global warming in earth’s atmosphere became a serious problem. The level of the sea rises by melting glaciers when global warming advances it. Forecasting the changes of carbon dioxide concentration is a major issue to maintain the stability of the Earth and its species. The measurement of carbon dioxide is also important for agriculture and local industrialization. The density of carbon dioxide varies depending on the environment. The development of a low cost device that detects carbon dioxide density is discusses in this paper. We developed some measurement systems of carbon dioxide for various purpose.

At present, our world is facing environmental issues, which is an increasing amount of carbon dioxide (CO2) generated by the Portland cement (OPC) production. To reduce that carbon dioxide emissions, some researchers have studied the alternative cementitious materials to replace the consumption of OPC, and geopolymer is one of the choices. Geopolymer cement (GP), a green technique for construction material, was applied for the road constructions by using Crushed rock (CR-the typical pavement material) as a starting material of geopolymer synthesis. The results showed that the optimum mixture to achieve both properties and economic aspect was 5M of NaOH concentration, 1.0 SS/SH ratio, 0.5 L/B ratio cured at room temperature. With that mixture, it passed the target compressive strength of Cement-treated base (CTB) for pavement (2.1-5.5 MPa) as well as achieving the CO2 reduction of 45.23% when compared to ordinary Portland cement.

Current Implementation

Carbon dioxide is one of the most important greenhouse gases which have caused the global warm. Reducing greenhouse gases, especially carbon dioxide emission, has become the hot spot of environmental issues in the current society of international world. Based on the analysis of carbon dioxide emissions in the global environment and the present introduction of carbon tax as a tool for reducing carbon dioxide emissions, the paper, on a unique perspective, compared some related conceptions in deep and analyzed the principle of the means in reducing carbon dioxide from the perspective of macro and micro. Finally, the paper gave the conclusion of China's carbon tax in the current implementation of specific measures.
