Forests can play an important role in mitigating the impacts of climate change by reducing atmospheric carbon dioxide.The purpose of this study is to quantified carbon storage and sequestration by forests and carbon emissions from energy consumption by several energy types in Tianjin,China,as well as the role of forests on offsetting carbon emissions from fossil fuel combustion.Data used for this study were collected according to the sixth national forest inventory(1999-2003) and China energy statistical yearbook.The results showed that the forests including natural forests and plantation forests in Tianjin stored 571,151.24 t C,with a carbon sequestration rate of 27,311.79 t C/yr. carbon storage per ha was 14.65 t C, and carbon sequestration per ha was 0.87 t C/yr. Carbon emissions from energy consumption in Tianjin were 3.85×107 t C /yr. The carbon stored by forests equaled to 1.48% of the annual carbon emissions from fossil fuel combustion, and carbon sequestration could offset 0.07% of the annual carbon emissions in Tianjin. In addition, the results indicates that the carbon storage and sequestration rate varied among forest types with different species and age structure. They provide insights for decision-makers and the public to better understand the role of forests, and make better management plans for forests.

Using a growth model that accounts for environmental and climate externalities, we take a closer look at the welfare effects of promoting biomass growth and the use of bioenergy, and especially the role of carbon neutrality. As an illustration, a hypothetical intensive forest cultivation project is simulated. Costs and benefits of the project show that only determining the postive effects of promoting biomass growth and the use of bioenergy, such as substitution away from fossil fuels and carbon sequestration is not sufficient. But more importantly, to achieve a balanced measure of the effects on the climate, we must also incorporate all carbon emissions that are associated with bioenergy. Not doing so will over-estimate the positive climate effects of increasing the use of bioenergy.

Timber harvesting is an activity in producing wood to supply the lumber industry. However, timber harvesting brought consequences such as decreasing carbon sequestration potential of natural forests. This study aimed to determine the reduction in the potential for carbon sequestration due to timber harvesting in natural forests. Data were collected using non-destructive methods through stand inventory before felling for all tree species, cruising results report, and tree distribution maps. Biomass was calculated using the existing allometric, and carbon stocks were calculated using the Intergovernmental Panel on Climate Change method. The results showed that there were 238 trees (65.29 m3) of stands in the study area (6 ha) based on stand inventory before felling. Potential biomass and carbon storage before trees felling were 16.12 ton ha-1 and 7.58 ton ha-1, respectively. Potential biomass and carbon storage after tree felling were 5.15 ton ha-1 and 2.42 ton ha-1, respectively. Carbon absorption before and after tree felling is 28.37 ton CO2eq ha-1 and 4.44 ton CO2eq ha-1, respectively. Carbon emissions during tree felling was 18.93 ton CO2eq ha-1 (81.00%). The application of environmentally friendly wood harvesting shall be carried out appropriately to minimize a decrease in carbon absorption from timber harvesting.  Keywords: biomass, carbon emission, timber harvesting
