Umwelt-Indikator

Indicator: Renewable energy

A graph shows the share of renewable energies in gross final energy consumption and gross electricity consumption. The share in gross electricity consumption rose from 6.3 percent in 2000 to 45.4 percent in 2020. The share in gross final energy consumption rose from 6.2 to 19.6 percent from 2004 to 2020.

The share of renewable energies in electricity consumption increased from 6.3 % to 45.4 % between 2000 and 2020.Therefore, the target range of 40 to 45 % for the year 2025 was already exceeded in 2020.The share of renewables in gross final energy consumption increased from 6.2 % (2004) to 19.6 % (2020).According to preliminary calculations, the goal of increasing the share of renewables in gross f... read more

Indicator: Global surface temperature

A graph shows the deviation of the global air temperature between 1850 and 2020 from the average global air temperature from 1850 to 1900, which is taken as the baseline period. 2020 was 1.2 degrees Celsius warmer than the baseline average.

2020 was the second warmest year worldwide since records began, with a very slight distance to the warmest year to date, 2016.The last six years have been the warmest years worldwide since 1850.The Paris Climate Agreement stipulates that the increase in global temperature should be limited to well below 2 °C above pre-industrial levels, and even to 1.5 °C. Due to historical data availability, the... read more

Indicator: Hot days

A graph shows the number of hot days in the areal mean for 1951 to 2020. 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 and 2018.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

The transnational impacts of global climate change

Containerterminal

Climate change will affect the frequency, intensity and regional occurrence of extreme weather events and lead to gradual climatic changes. Although impacts appear locally at first, they spread beyond political borders due to the global physical and economic interconnectedness. A new UBA report provides an overview of the potential impact chains of global climate change on the German economy. read more

Natural Hazards Triggering Technical Accidents (Natech)

Lightning and technical installation

Examples like the earthquake and tsunamis 2011 in Japan and the devastating hurricane Harvey 2017 in the USA, make aware that natural hazards not just cause destruction of private houses but also led to accidents at installations containing hazardous substances. They can cause releases of hazardous substances, fire, and explosions endangering people and significantly pollute the environment. read more
