CO2 capture from gaseous effluents is one of the great challenges faced by chemical and environmental engineering, as the increase of CO2 levels in the Earth's atmosphere might be responsible for dramatic climate changes. This compilation begins by presenting the recent developments in studies focusing on the optimization of CO2 capture using amine solutions. The authors assess the effects of land use change on soil carbon flux in Brazil, in addition to contributing to the body of knowledge about carbon stock balance in tropical and subtropical domains. The authors also assess whether it will it be possible to fulfill the Brazilian Paris agreement goals if the Amazon deforestation increase continues. The potential inflation effects of a global carbon price on consumer prices, investment prices, export prices, and import prices are explored, estimating the effects under various scenarios.
