17 Working methods Another important aspect of our preventive work is to spread knowledge about our work and our findings, the situation of people deprived of their liberty in Norway and the national risk factors we have identified. We do this by contributing to seminars, giving lectures, providing training and engaging in dialogue with relevant institutions (see Activities in 2019). International dialogue and cooperation are also important in our preventive work. The NPM cooperates and exchanges information with international human rights bodies. The national preventive mechanisms of other countries are also useful partners, and a special cooperation has been established between the national preventive mechanisms of the Nordic countries (see Chapter seven). The NPM's staff The NPM has an interdisciplinary composition and includes staff with degrees in the fields of law, criminology, sociology, psychology, social science and human rights. The NPM is organised as a separate department under the Parliamentary Ombudsman. The NPM does not consider individual complaints. External experts The NPM can call in external expertise for individual visits if this is considered necessary. External experts are assigned to the NPM's visit team during the preparation for and execution of one or more visits. They can also help to write the visit report and provide professional advice and expertise to the visit team. No external experts were consulted in 2019, because the number of visits decreased in order to make time to write the Special Report to the Storting on Solitary Confinement and Lack of Human Contact in Norwegian Prisons. The NPM's employees travel in the most environmentally friendly way possible. Climate friendly preventive work The National Preventive Mechanism's activities require a great deal of travel and extensive contact with other parties both nationally and ­internationally. In 2019, we focused on how we can limit our climate footprint within the scope of our work. We therefore choose to travel by train, if possible. If we have to travel by car, we do so in the same car and in electric cars when possible. The NPM also has meeting rooms with video equipment, which means that we can hold digital meetings with parties in locations outside Oslo. We traveled to Strasbourg by train in November.
