RIM+ is a Dutch acronym for Environmental Information and Planning Model (Reken‐ en Informatie‐systeem Milieuhygiene). It is currently under development at the National Institute for Public Health and Environmental Protection in the Netherlands. The objective is to generate projections of emissions, waste production and energy use (environmental load) for any pollutant, waste material or energy carrier. Also financial implications of environmental policies can be calculated. All these projections will be calculated using the same principle: the process method. By estimating the future development of processes and applying measures to reduce environmental load, the users of RIM+ will be able to generate these projections. The structure of RIM+ is strongly modular and some modules will be built in 1992, others in 1993.
