Air Pollution In Argentina: The Main Culprits

Argentina, like many other countries, faces environmental degradation in the form of air pollution. The sources of air pollution in Argentina are diverse and complex. From the deterioration of the Antarctic ozone layer, exposing both humans and livestock to harmful UV radiation, to the more localized air pollution in cities like Buenos Aires, where vehicular emissions and noise pollution are a significant concern. Argentina has taken steps to address these issues, such as joining the Climate and Clean Air Coalition in 2018 and implementing various national plans to reduce emissions and increase renewable energy sources. However, the country still faces challenges, including the import of nuclear waste and the threat of glacier destruction due to mining projects.

Motor vehicles

In response to this issue, Argentina has taken several measures to reduce emissions from motor vehicles. In 2018, the country joined the Climate and Clean Air Coalition (CCAC) and has since collaborated with partners to mitigate black carbon emissions from heavy-duty diesel vehicles. Additionally, Argentina established a National Cabinet of Climate Change in 2016 to drive down emissions in line with its Paris Agreement commitments. This led to the creation of national climate change action plans in various sectors, including transport.

The transport sector's decarbonization strategies are outlined in the 2017 National Plan for Transport and Climate Change. This plan aims to implement policies for urban mobility, cargo and heavy vehicle transportation, and inter-urban mobility to reduce greenhouse gas emissions. Argentina's commitment to addressing air pollution from motor vehicles is evident through its active participation in international agreements and the implementation of national strategies.

Furthermore, motor vehicles are also responsible for a significant portion of noise pollution in Argentina. According to a study, vehicular noise accounts for 80% of noise levels at certain intersections in Buenos Aires, exceeding 80 decibels. Buses and motorcycles are identified as the primary sources of this noise pollution, partly due to inadequate mufflers.

To summarize, motor vehicles contribute significantly to both air and noise pollution in Argentina. The country has recognized the urgency of this issue and has taken steps towards reducing emissions and noise pollution through various initiatives and policies. These efforts demonstrate Argentina's commitment to improving air quality and mitigating the health impacts of air pollution caused by motor vehicles.

Ozone layer depletion

Argentina, like many other countries, faces environmental issues, including air pollution. One of the main contributors to air pollution in Argentina is the depletion of the Antarctic ozone layer, which has exposed both humans and livestock in southern Argentina to harmful ultraviolet radiation.

The effects of ozone layer depletion are significant, as the ozone layer protects us from the sun's harmful ultraviolet rays. The depletion of this layer leads to increased exposure to ultraviolet radiation, which can have detrimental effects on both human health and the environment.

Argentina has been vulnerable to the impacts of ozone depletion, with a 50% increase in ultraviolet radiation measured in Ushuaia, southern Argentina, in December 1990. This incident was caused by the annual ozone hole, which is primarily located over the Antarctic. The hole is caused by CFCs, which, unlike chlorine from natural sources like seawater and volcanoes, travel to the stratosphere where the ozone layer is located.

To address ozone depletion, various countries, including Argentina, have launched programs and initiatives. Argentina has been at the forefront of promoting ozone protection internationally and has focused on reducing the consumption of hydrochlorofluorocarbons (HCFCs). Additionally, the Montreal Protocol, proposed in 1987, aims to stop the use, production, and import of ozone-depleting substances, and minimize their concentration in the atmosphere. While progress has been made, recovery at the Antarctic level is slower, and it is expected that the ozone layer will recover to its 1980 benchmark level by 2050 if countries continue to fully comply with the Montreal Protocol.

Nuclear waste

While there is no direct evidence that nuclear waste is the biggest contributor to air pollution in Argentina, it is certainly a significant environmental issue in the country.

Greenpeace Argentina has protested an agreement with Australia to import nuclear waste for reprocessing near Buenos Aires, which is prohibited by the Argentine constitution. Despite this, Argentina has its own nuclear reactor near the town of Lima, and the country has promoted nuclear power since the 1950s.

Argentina generates 200 cubic meters of low and medium-level radioactive waste per year, and scientists are working to identify the best methods to treat this waste. The IAEA is supporting the country with equipment and training, and Argentinian scientists are adapting existing methods to safely treat nuclear waste.

One potential treatment method is thermal decomposition, or waste gasification, which involves heating waste using ionized air to understand how to treat the sources and reduce their volume. Another method under consideration is vitrification, which entails heating sources to extremely high temperatures so that they can be bonded into a highly resistant type of glass. This results in a solid waste form that will remain stable for thousands of years.

Energy sector

The energy sector in Argentina is recognised as the sector with the highest potential for mitigation of air pollution. The country has been working to reduce black carbon emissions from heavy-duty diesel vehicles and engines. In 2018, Argentina joined the Climate and Clean Air Coalition (CCAC) and has since developed an integrated national plan to target short-lived climate pollutants across multiple sectors.

The country's energy sector is addressed by the 2017 National Plan for Energy and Climate Change, which outlines measures and laws to address both the supply and demand sides of energy usage. The plan aims to increase the use of renewable energy sources such as biofuels and improve energy efficiency in households. To encourage this, the Ministry of Energy and Mining launched the RenovAr Auction Programme, which provides financial support for renewable energy projects. This has been a driving factor in Argentina's increasing adoption of renewable energy sources.

Despite these efforts, Argentina still faces challenges in the energy sector. The country has a history of relying on fossil fuels, with ageing diesel buses and private vehicles contributing significantly to air pollution in urban areas. Additionally, there has been mismanagement and disinvestment in the fossil fuel industry, leading to a decrease in self-sufficiency and the need to import natural gas from Bolivia.

To improve the situation, Argentina has set a target of reducing greenhouse gas emissions in the agriculture sector, the second-largest emitter in the country, by 25.75 Mt CO2e by 2030. The country has also been promoting nuclear power since the 1950s, and the 357-megawatt Atucha I reactor has powered the capital's electrical grid since 1974. However, it has mostly operated at reduced capacity due to cheaper alternatives and inadequate maintenance.

Greenhouse gases

Argentina, like many other countries, faces environmental degradation, including air and water pollution. In 2022, Argentina's emissions rebounded above 2019 levels, and the country's 2030 emissions projections are approximately 15% above its already unambitious target for that year.

The energy sector, led by fossil fuels, contributes 37% of the country's greenhouse gas emissions. Argentina has been investing heavily in fossil fuels, including a USD 30 billion LNG terminal to export fossil gas from Vaca Muerta. The country also has a 357-megawatt nuclear reactor near the town of Lima. However, the government has promoted nuclear power since the 1950s and has plans to develop renewable energy sources and increase energy efficiency.

Agriculture is another significant contributor to greenhouse gas emissions in Argentina, accounting for 39% of GHG emissions in 2018. Nitrous oxide, a strong greenhouse gas, is mainly produced from agricultural activities, such as the use of synthetic and organic fertilizers. Pursuing decarbonization in the agricultural sector is crucial for reducing emissions and increasing carbon sequestration.

To address these issues, Argentina has committed to achieving carbon-neutral development by 2050. The country aims to reduce its emissions through a decrease in deforestation and the implementation of climate-smart agricultural practices. According to the World Bank, transitioning to a low-carbon economy can boost Argentina's economic growth and the well-being of its people.
