As an important component of Volatile Organic Compounds (VOCs) in atmosphere, the Biogenetic Volatile Organic Compounds (BVOCs) has crucial effects on climate and environment. This paper collected and reviewed existing studies. Firstly, on the basis of reviewing gas-phase of chemistry processes of BVOCs from the existing studies, we described mechanisms in which BVOCs lead to the O ₃ pollution and Secondary Organic Aerosol (SOA) pollution. The importance of BVOCs on the formations of O ₃ and SOA pollutions were thereby highlighted. Secondly, through reviewing on the existing studies, we summarized two pathways in which BVOCs regulate the earth climate. One pathway is modifying radiation budgets of low level of atmosphere through transforming into SOA. The other pathway is taking part in the carbon cycle of earth to modify the lifetime of greenhouse gases, such as CH ₄ and CO. The latest researches on the climatic effects of BVOCs exhibiting on the two pathways were also summarized. Thirdly, along with the temporal ways, the development history of emission model of BVOCs was reviewed and the present measurement technology of BVOCs was summarized. The advantages and disadvantages of models and successions of models were reviewed.The present status on the coupling climate model and BVOCs emission model was also depicted. Finally, on the basis of general picture of existing studies, we proposed two research directions which should be enhanced to improve our understanding on the climatic and environmental effects of BVOCs. One direction is studying the oxidation mechanism of BVOCs in the atmosphere and physical and chemical properties of the oxidation products. The other direction is developing new earth system model with coupling the emission and chemistry process of BVOCs.
