Along with continuous progress in the reduction of emissions from road vehicles, the Non-Road Mobile Machinery (NRMM) becomes a more and more important source of emissions.
Namely, although the EU Regulation 2016/1628 for NRMM introduces the latest limit emission values known as Stage V, their values are still considerably higher than those of road vehicles. Also, the average age of the NRMMs is always significantly higher than the average age of road vehicles. Additionally, a significant share of NRMM is used in highly urbanised areas.
To enable the emission inventories of higher quality, it is necessary to enable a better data collection on usage and working conditions of NRMM required for the development of emission inventories.
With that goal in mind, an organisational scheme for implementation of rules on type approval for Non-Road Mobile Machinery in the Republic of Croatia is proposed. Besides, an organisational scheme for market surveillance is proposed. An additional benefit of proposed market surveillance is the collection of data and development of corresponding emission factors for NRMMs.
