gaz sf6-policy development in the Netherlands

As shown in this paper the Netherlands tries to develop a balanced policy for ncgg’s in close co-operation with industry. With its active approach the Netherlands policy strives for the use of switchgear that reduces overall greenhouse gas emissions. This will include insulating gas-insulated switchgear for the foreseeable future.
