Effective joint environmental resource management is essential to ensure environmental sustainability and reduce environmental accidents. According to statistics, CBRN accident rates in the Latvia and Lithuania is increasing every year, which oblige us to think about the development of joint actions in order to reduce such accidents. Therefore State Fire and Rescue Service of Latvia, Utena county Fire and Rescue board and Visaginas county Fire and Rescue board joint project aim is to reduce environmental risks and to fight together against environmental accidents of chemical, biological and, in particular radioactive material leakage and contamination. That can be achieved with cooperation and strengthening the capacities and capabilities during CBRN accidents on Latvian and Lithuanian border area. During project implementation, it is planned to do joint exercises, training courses, and workshops and purchase a compatible equipment. Since through the Latvian and Lithuanian borders are frequently transported hazardous substances, as well as the border area is located in high-risk sites such as the Ignalina nuclear power plant in Visaginas, it is particularly important to improve cooperation between both countries and service capabilities of CBRN incidents and decontamination. This project will not only improve the Latvian and Lithuanian Fire and Rescue Service and co-operation skills, but also promote public awareness and knowledge of the behavior and safety of CBRN contamination and accidents.
