Umwelt-Indikator

Indicator: Nitrate in groundwater

A graph shows the proportion of groundwater sampling sites where nitrate measurements for the years 2008 to 2022 were above 25 and 50 milligrams per litre. In the period covered, neither sub-indicator has shown any significant change.

The European Nitrates Directive, the Groundwater Directive and the German Groundwater and Drinking Water Ordinances require that exceedances of the limit value for nitrate of 50 milligrams per liter be prevented.Since 2008, the quality standard has been exceeded every year at almost one in six measuring points.Extensive changes to the fertilizer legislation have allowed the designation of particul... read more

Indicator: Grasslands

A graph shows the area of permanent grassland and its share of the total agricultural area from 1991 to 2023. Both indicators have been declining until 2013 and have then increased in the years that followed. Most recently, the values have stagnated.

Between 1991 and 2023 the area of grassland in Germany decreased by around 12 %.The area of permanent grassland has almost remained at the same level in recent years.The loss of grassland was largely halted with the 2014 agricultural reform, and the area of grassland has not fallen below the 2013 level since then. Effective steps are required to achieve this target. read more

Indicator: Combined heat and power (CHP)

A graph shows the development of CHP net power generation from 2003 (78 terawatt hours) to 2022 (109 terawatt hours) and the target for 2025 according to the CHP Act.

The volume of electricity generated by combined heat and power (CHP) has been increasing almost steadily until 2017.The decline in CHP electricity generation between 2017 and 2018 is due to a change in energy statistics: Since 2018, CHP plants have been recorded more accurately.The CHP Act stipulates that CHP should generate 120 terawatt hours (TWh) of electricity in 2025.The target of 110 TWh for... read more

Indicator: Hot days

A graph shows the number of hot days in the areal mean for 1951 to 2023. Although the trend varies greatly, the increase is clearly visible. A trend line has also been plotted on the graph which shows a significant rise.

The highest number of hot days averaged across Germany were recorded in 2003, 2015, 2018 and 2022.Despite considerable fluctuations between individual years, the overall trend is rising significantly.More hot days are expected during summer months in the coming decades due to climate change. read more

Indicator: Nitrogen eutrophication

A graph shows the proportion of vulnerable ecosystems in Germany where the critical loads for eutrophication were exceeded between 2000 and 2019 and the target for 2030. In 2000, the share was 84 % and in 2019, it was 69 %.

69 % of vulnerable ecosystems in Germany are threatened 2019 by excess nitrogen deposition.With the revised German Sustainable Development Strategy 2016, the Federal Government aims to reduce the proportion of these areas by 35 % until 2030. According to the current calculation basis, this results in a target value of 52 % by 2030.This target is feasible only if efforts to reduce air pollution are... read more

Indicator: Agricultural nitrogen surplus

A graph shows the agricultural nitrogen surpluses for individual years and as rolling 5-year means between 1990 and 2021. The 5-year-mean nitrogen surpluses in kilogrammes per hectare dropped from 117 to 82. The target for 2030 is 70 kilogrammes per hectare and year.

The five-year average of nitrogen surplus of the total balance per hectare of utilized agricultural land has decreased by 30 % since 1992.The Federal Government aims to reduce the average nitrogen surplus of the total balance of the years 2028 to 2032 to 70 kilogrammes per hectare of agricultural land.If the trend of the last 10 years continues, the target will be reached. read more

Indicator: Species diversity and landscape quality

A graph shows the development of the population of representative bird species for different landscapes and the development of an aggregate indicator for 1970, 1975 and from 1990 to 2019 in percent. The aggregate indicator decreases significantly from 214 in 1970 to 75 in 2019.

In 2019 the indicator was at 75.3 percent and remains far from the target value of 100 percent.Particularly the values of the sub-indicators for agricultural land and inland waters have shown a negative development in recent years.In the German Sustainable Development Strategy, the Federal Government envisages that the indicator should rise to 100 percent by 2030. Considerable additional effort is... read more

Misleading calculation: EU plans for pesticide reduction at risk

Traktor besprüht ein Feld

The use of pesticides is to be halved by 2030, according to the draft EU regulation on pesticide reduction. This goal is to be verified using pesticide sales data. In the view of the German Environment Agency this method is misleading. Pesticides that are no longer approved are weighted too high. Decreasing sales figures would indicate a decreasing trend, which does not happen in the field. read more
