  In terms of climate protection, one of the most important questions is the reduction of the GHG emission. In this study, I compared CO2 -emission of households heated by natural gas and firewood, which had similar heated area and volume of air, considering the carbon-dioxide absorbing of forests of the households heated by firewood. Natural gas is a fossil fuel; however, the firewood (solid biomass) is a renewable energy resource. One of the main features of renewable energy sources is to get into the atmosphere less CO2 than fossil fuels. The renewable energy resources emit into the air just as much CO2 as they absorb during their life cycle.

  Greenhouse gas emissions resulting from anthropogenic activities play a significant role in climate change. The residential heating should be mentioned one of the main polluting source of greenhouse gases.This paper aims to give a comprehensive view about the amount of CO2 emission as well as objectives and strategies for reduction the GHG emission. In addition, we illustrate the example of an average Hungarian family house (100 m2 ), that biomass-based energy production what extent can reduce the current very high degree carbon dioxide emissions. We prepared investment analysis, as to what kind of ecological and economic benefits may result in heating modernization projects of a four-member family home. Additionally, a calculation method of CO2 emission from heating is demonstrated on the basis of IPPC report (2006); the role of biomass is explained in heating; furthermore I give an overview analysis about the significance of forests for reduction of CO2 concentration.
