Abstract
Several international agreements, focused on regulating greenhouse gases emissions in the atmosphere, were created due to the growing concern about the climate change due to human action. The carbon dioxide (CO2) emissions account for more than 70% of the total greenhouse gases emissions; among the CO2 emitting sectors, electricity generation accounts for 25% of the global emissions. CO2 emissions from Brazilian power plants motivated their mapping, a method was proposed to performance a local market analysis for potential products from CO2 chemical conversion. The forecast behavior of this market for 2030 was also calculated. Among the studied products, methanol, polycarbonates, formic acid and acetaldehyde are the most promising for local manufacture. The States of Sao Paulo, Parana, Amazonas, Bahia, Rio Grande do Sul and Santa Catarina are the most promising regions in terms of potential of CO2 utilization.
Highlights
The increasing concern about the environmental impact generated by global warming has stimulated a series of international agreements aimed at regulating greenhouse gases (GHG) emissions in the atmosphere
There is a wide variety of approaches, for example analytic hierarchy process (AHP) (Saaty, 1977), Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) (Brans and Vincke, 1985), Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) (Behzadian et al, 2012; Hwang and Yoon, 2012) and the simple additive weighted (SAW) method (Kirkwood and Corner, 1993) which have been successfully utilized in dealing with Multiple criteria decision analysis (MCDA) problems
A time series forecasting model is designed to handle the common features of the business time series of imports and exports
Summary
The increasing concern about the environmental impact generated by global warming has stimulated a series of international agreements aimed at regulating greenhouse gases (GHG) emissions in the atmosphere. In 2016, total global GHG emissions continued to increase steadly by about 0.5% (±1%), to about 53.4 Gt CO2-eq (including land use, land-use change and forestry emissions, estimated at about 4.1 Gt), the slowest since the early 1990s, except for global recession years, according to Olivier et al (2017). This result is justified by the partial replacement of coal consumption from fuel to natural gas and the increasing renewable power generation (wind and solar power, mostly)
