In view of the great contribution of coal-fired units to CO2 emissions, the coupled coal and power system with consideration of CO2 mitigation is a typical sub-system of the highly emitting Chinese energy system for low-carbon studies. In this study, an inexact mix-integer two-stage programming (IMITSP) model for the management of low-carbon energy systems was developed based on the integration...

A key aspect of sustainable development in a country is how energy, environment and economic sectors interact. Greenhouse gas emissions and their impacts are among important environmental issues that have been in focus. The increase in the concentration of these gases in atmosphere to levels above the natural level results in global warming, depletion of the Earth’s protective layer against har...

Urban forest management and policies have been promoted as a tool to mitigate carbon dioxide (CO2) emissions. This study used existing CO2 reduction measures from subtropical Miami-Dade and Gainesville, USA and modeled carbon storage and sequestration by trees to analyze policies that use urban forests to offset carbon emissions. Field data were analyzed, modeled, and spatially analyzed to comp...

Preliminary analysis indicates that careful consideration of non-CO2 greenhouse gas emissions and sinks from a variety of sources as provided in the Kyoto Protocol is warranted. Sources, projections, abatement options and uncertainties in these estimations are investigated in support of Post-Kyoto assessments of burden sharing in the European Union. Despite large uncertainties, evidence is give...

It is clear that city must be part of the solution if an urbanizing world is to grapple successfully with ecological challenges such as energy depletion and climate change. A system dynamics model was developed in this study using STELLA platform to model the energy consumption and CO2 emission trends for the City of Beijing over 2005–2030. Results show that the total energy demand in Beijing i...

the gaseous composition of the earth's atmosphere is changing at an accelerated rate because of the influence of human activities. different factors can cause increasing air contamination such as co2. understanding factors affecting atmosphere gaseous change is important for management and reducing air contaminants. the aim of this paper is to investigate factors affecting on co2 emission ...

To achieve a low-carbon economy, China has committed to reducing its carbon dioxide (CO2) emissions per unit of gross domestic product (GDP) by 40%–45% by 2020 from 2005 levels and increasing the share of non-fossil fuels in primary energy consumption to approximately 15%. It is necessary to investigate whether this plan is suitable and how this target may be reached. This paper verifies the fe...

[1] A coupled atmosphere-ocean-carbon cycle model is used to examine the long term climate implications of various 2050 greenhouse gas emission reduction targets. All emission targets considered with less than 60% global reduction by 2050 break the 2.0 C threshold warming this century, a number that some have argued represents an upper bound on manageable climate warming. Even when emissions ar...

The purpose of this study is to conduct the financial and emission analysis of the Lahendong site as a case study of geothermal powerplant in Indonesia. The outputs of energy model in RETScreen worksheet are power capacity, electricity generation, annual GHG emission reduction, the Internal Rate Return (IRR) and payback period. The sensitivity analyses also were carried out at two scenarios (no...
