The industrial sector dominates the global energy consumption and carbon emissions in end use sectors, and it faces challenges in emission reductions to reach the Paris Agreement goals. This paper analyzes and quantifies the relationship between industrialization, energy systems, and carbon emissions. Firstly, it forecasts the global and regional industrialization trends under Representative Concentration Pathway (RCP) and Shared Socioeconomic Pathway2 (SSP2) scenarios. Then, it projects the global and regional energy consumption that aligns with the industrialization trend, and optimizes the global energy supply system using the Model for Energy Supply Strategy Alternatives and their General Environmental Impact (MESSAGE) model for the industrial sector. Moreover, it develops an expanded Kaya identity to comprehensively investigate the drivers of industrial carbon emissions. In addition, it employs a Logarithmic Mean Divisia Index (LMDI) approach to track the historical contributions of various drivers of carbon emissions, as well as predictions into the future. This paper finds that economic development and population growth are the two largest drivers for historical industrial CO2 emissions, and that carbon intensity and industry energy intensity are the top two drivers for the decrease of future industrial CO2 emissions. Finally, it proposes three modes, i.e., clean supply, electrification, and energy efficiency for industrial emission reduction.

The article presents a comprehensive analysis of the development of the global energy market, highlights the key stages and gives their distinctive characteristics. Steady tendencies of each stage are revealed taking into account the dynamics and structure of changes in the fuel and energy balance at the level of macroregions and individual countries. It is shown that the dynamics and structure of the use of various energy carriers is uneven throughout the continuation of the development of human society. Particular attention is paid to the greening of the economy, the study of the causes and consequences of increased CO2 emissions, the impact on the economy.

Recently, cutting the CO2 emissions has been the worldwide problem. In order to reduce the CO2 emissions, it is important to promote the energy conservation and introduce the sustainable natural energy. In this paper, we have been studied to develop a combination energy system of the energy conservation and the natural energy in the Okayama Prefectural University. We have a result that it is possible to cut off the 36% or more CO2 emission with the combination of (1) replacing the air-conditioner from the absorption type to a heat pump type, (2) introducing photovoltaic power generation and (3) changing the car that is used for commute from the internal-combustion engine type to an electric vehicle (EV). In addition to cut the CO2 emission, the studied combination energy system can be presented the high economically method.
