Environment - Latvia
PRB monitoring
▪ Latvia achieved a KEA performance of 1.24% compared to its reference value of 1.30% and therefore contributed positively towards achieving the Union-wide target.
▪ As well as benefitting from lower traffic levels, Latvia will implement A-CDM in 2021, which is expected to deliver almost 1,000 tons of CO2 savings per year. However, the KEA performance in 2020 was worse than in 2016 and since the shortest constrained routes in Latvia in 2020 were 1.14%, the PRB believes further improvements (in addition to the already good performance) are possible.
▪ Only one out of four Latvian airports that are regulated reported terminal data.
▪ The share of flights operating CCO/CDO at Latvian airports worsened in 2020 compared to 2019. Latvia’s commitment to implementing PBN should improve this performance in the future. The additional time airspace users spent taxiing or holding in terminal airspace reduced by 20% compared to 2019.
