Germany's Fight Against Air Pollution: Strategies And Solutions

Germany has been taking steps to tackle air pollution, with a significant decrease in recent years. However, the country still faces challenges in meeting updated air quality standards, particularly in urban areas. Germany's air pollution is largely due to transportation, industry, and energy sources. To improve air quality, Germany has implemented measures such as feed-in tariffs for electricity to encourage renewable energy technologies, the establishment of environmental zones, and participation in EU emission standards regulations. Germany's Federal Ministry for Economic Cooperation and Development (BMZ) has an opportunity to champion air quality globally. While Germany works towards meeting EU standards, it has been taken to court by the European Commission for failing to comply with air pollution laws.

Germany's transition to renewable energy sources

Germany's renewable energy use rate has increased significantly, from 6.3% in 2000 to 34% in 2016. This transition has been facilitated by feed-in tariffs (FiT) for electricity, which provide incentives for the adoption of renewable energy technologies such as wind power, biomass, hydropower, geothermal power, and solar photovoltaics. Germany's progress in this area has led some to view it as a leader in climate change and renewable energy policy within the European Union and the world.

However, Germany's CO2 emissions per capita are among the highest in Europe, and it has faced criticism and legal action from the EU for failing to meet air pollution standards. Germany's Environment Agency (UBA) predicts that compliance with updated thresholds is achievable by 2030, but this will require addressing the transport sector, which is responsible for a significant proportion of particle emissions, particularly in cities.

The German government has implemented an "immediate action program for clean air" which includes measures such as equipping public buses with exhaust-scrubbing systems and increasing charging points for electric cars. Germany has also established 36 "environmental zones" which have been effective in reducing air pollution, with associated health benefits for residents.

Overall, Germany's transition to renewable energy sources has been driven by a combination of economic, environmental, and political factors, and while progress has been made, further efforts are needed to tackle air pollution and meet international standards.

Transboundary air pollution control policy

Germany has been working to improve its air quality over the past few decades, and it has made significant progress. However, as a country located in central Europe, Germany is susceptible to transboundary air pollution, where air pollution travels across borders from neighbouring countries. To address this issue, Germany has developed and implemented a transboundary air pollution control policy, recognising the importance of international cooperation in improving air quality.

Germany's transboundary air pollution control policy involves active participation in European and international dialogues on air pollution control measures. This includes engaging with other countries and organisations to share knowledge, discuss strategies, and develop collaborative solutions. Germany has been influenced by the environmental policies of countries such as the United States, Japan, Sweden, and Great Britain, and has also learned from their experiences in establishing new environmental institutions, procedures, and technologies.

One of the key strategies employed by Germany to address transboundary air pollution is the introduction of feed-in tariffs (FiT) for electricity. These tariffs encourage the adoption of renewable energy technologies such as wind power, biomass, hydropower, geothermal power, and solar photovoltaics. By providing remuneration above the retail or wholesale rates of electricity, Germany incentivises the use of cleaner energy sources, reducing the country's dependence on fossil fuels and decreasing its economic-political vulnerability.

In addition to its focus on renewable energy, Germany has established 36 "environmental zones" as part of its transboundary air pollution control policy. These zones have been effective in reducing air pollution, particularly in urban areas. The implementation of these zones has resulted in decreased levels of PM10 and NO2, leading to positive impacts on public health, including reductions in asthma medication use, depression and anxiety diagnoses, and related healthcare costs.

While Germany has made strides in improving air quality through its transboundary air pollution control policy, there are still challenges to be addressed. Germany's transport sector, for example, remains a significant contributor to air pollution, with a growing number of cars on the road and only a small percentage of electric vehicles. Additionally, Germany has faced criticism and legal action from the EU for failing to meet air pollution standards, particularly in cities like Stuttgart, where NO2 levels have exceeded the allowed threshold. Nonetheless, Germany remains committed to improving air quality and continues to work towards meeting the standards set by the EU and its own ambitious climate goals, such as those outlined in the German Climate Action Plan 2050.

The role of the German Environment Agency (UBA)

The German Environment Agency (Umweltbundesamt – UBA) was established on 22 July 1974 through the Act creating a Federal Environment Agency. It is Germany's central environmental authority, and its primary responsibilities include researching, advising, and informing on environmental protection, the environment, and health.

UBA supports the Federal Environment Ministry in matters related to pollution control, waste and water management, and environmental health concerns. This includes drafting legal and administrative regulations, researching and developing the basis for appropriate measures, and testing and investigating procedures and establishments.

UBA plays a crucial role in enforcing various laws, such as emissions trading, the Plant Protection Act, the Electrical and Electronic Equipment Act, and the EU REACH regulation. Additionally, UBA is tasked with raising awareness about environmental issues. To this end, they provide access to extensive databases, regularly publish the "Data on the Environment" indicator report, and maintain the largest environmental library in a German-speaking country.

UBA is also a key partner and point of contact for numerous international organizations. Its staff actively participates in several international committees, including the WHO Collaborating Centre for Air Quality Management and Air Pollution Control (WHO CC) and the National EU Air Quality Reference Laboratory.

UBA has been instrumental in Germany's transition to renewable energy sources, helping the country become a leader in climate change and renewable energy within the European Union and the world. It has set ambitious goals, such as the German Climate Action Plan 2050, and continues to work towards reducing greenhouse gas emissions and improving air quality.

The impact of diesel vehicles

Germany has been taking steps to address air pollution, and while it has made progress, it still has work to do. A large proportion of pollution in Germany is due to transportation, and motor vehicles are a significant contributor to this.

The rise in diesel engine production and usage in Europe, including Germany, has had a considerable adverse impact on air quality. Diesel vehicles produce 15% less CO2 than petrol engines, but they emit four times more nitrogen dioxide pollution (NO2) and 22 times more particulates—the tiny particles that can penetrate the lungs, brain, and heart. This increase in nitrogen dioxide and particulate matter has had negative consequences for public health. Studies have shown a correlation between air pollution and the occurrence of skin issues, such as eczema, and psychological health issues, including chronic stress.

The German government has recognized the need to address transboundary air pollution and has actively engaged in dialogues at the European and international levels. Additionally, Germany has implemented feed-in tariffs (FiT) to encourage the use of renewable energy technologies. Despite these efforts, Germany's air quality remains an issue, and in 2019, it ranked 25th in the World Air Quality Report.

To further combat the issue of diesel emissions, Munich, a city in Germany, implemented a selective diesel vehicle ban within its existing low-emission zone in February 2023. This ban targeted Euro 4 and older diesel vehicles to reduce NO2 concentrations. However, the ban's effectiveness has been limited, possibly due to exemptions, unclear enforcement, and a focus on older diesel vehicles.

Germany continues to face the challenge of improving air quality and reducing the impact of diesel vehicles on pollution levels and public health. The country's efforts to transition to renewable energy sources and implement selective diesel vehicle bans demonstrate its commitment to addressing these issues.

The importance of reducing greenhouse gas emissions

Germany has made efforts to reduce air pollution and its greenhouse gas emissions, with some success. However, there is still a long way to go, and the country has faced criticism and legal action from the EU for its air pollution levels.

Secondly, transitioning to renewable energy sources and reducing emissions is essential for mitigating climate change. Germany has made notable progress in this area, increasing its renewable energy use rate from 6.3% in 2000 to 34% in 2016. This shift not only reduces emissions but also decreases Germany's dependence on uncertain foreign sources of fossil fuels, thereby reducing their economic and political vulnerability.

Thirdly, the development and implementation of green technologies and renewable energy sectors create new jobs and foster economic growth. Germany's efforts to adopt cleaner technologies have resulted in the creation of economic "winners," demonstrating that environmental protection and economic growth can go hand in hand.

Furthermore, reducing greenhouse gas emissions is crucial for meeting international commitments and standards. Germany has set ambitious goals, such as the German Climate Action Plan 2050, and is actively involved in dialogue at the European and international levels to address transboundary air pollution. By taking a leadership role in this area, Germany can inspire and influence other nations to follow suit.

Lastly, while Germany has made strides in reducing air pollution, there are still critical areas that need attention, particularly the transport sector. High nitrogen oxide levels, largely due to diesel cars and trucks, remain a significant concern. Encouraging the use of electric vehicles, improving public transportation, and promoting active mobility are essential steps towards reducing emissions from transportation and improving air quality.
