Mapping air pollutant emissions in the Republic of Moldova with UNECE support

A map of air pollutant emission sources of a given country can help experts and decision-makers understand which policies are most viable. Spatial allocations of emissions are also important to understand where emissions are coming from on a regional level.

Spatially allocating – or gridding – emissions is technically complex. It requires applying the gridding matrix to the inventory emissions to transform source-based inventory emissions to gridded emissions. Under the UNECE Convention on Long-range Transboundary Air Pollution (Air Convention), Parties now report gridded emissions in a 0.1° x 0.1° longitude-latitude spatial resolution. The fine resolution can help attribute emissions more precisely on the map.

To assist the Republic of Moldova in developing gridded emissions, UNECE organized a workshop in Chisinau this week (29-31 October 2018). The training programme for the workshop focused on both theoretical and practical work, covering a number of activities in various sectors. In particular, participants discussed the methods and tools used to collect and process relevant data for the calculation of grid emissions and emission projections. This was followed by practical work and interactive discussions and exchanges.
