Integrated assessment of carbon and sulphur emissions, simulations with the CLIMNEG model

چکیده
Combustion of fossil fuels causes carbon emissions which contribute to global climate change. But combustion processes are also responsible for sulphur emissions and sulphate aerosols o set part of the global warming problem since they increase locally the albedo of the Earth's atmosphere. However, sulphate aerosols contribute to the regional acidi cation and acid rain problem. Integrated assessment analysis of climate change should incorporate these interactions between global and local environmental problems in a consistent way. This paper describes in a theoretical framework the trade o between carbon and sulphur emission control. Necessary conditions are derived for optimal investment, carbon and sulphur emission control rates in a Nash equilibrium and are compared to Pareto e cient policies. The theoretical results are illustrated by means of a numerical simulation model.

Introduction: Carbon stored in soils particularly in arid rangelands soils is the most significant carbon sink in terrestrial ecosystems. In arid rangelands, Soils have special places in both carbon sequestration and mitigate global warming. Therefore, any small change in the soil organic carbon (SOC) leads to a significant impact on the CO2 concentration in the atmosphere. Studies have shown t...
متن کاملA Novel Hybrid Whale Optimization Algorithm to Solve a Production-Distribution Network Problem Considering Carbon Emissions
Nowadays, there is a great deal of attention for regulations of carbon emissions to enforce the decision-makers of production and distribution networks to redesign their systems satisfactorily. The literature has seen a rapid interest in developing novel metaheuristics to solve this problem as a complicated optimization problem. Such difficulties motivate us to address a production-distribution...
