Clean Air Act gives legal tools to address the issue of transport pollution. However, Congress did not specifically give States the legal authority for them to act within their own deadlines. As a result, EPA has developed a policy to resolve this tension between deadlines. This policy was created to allow upwind areas to take responsibility for their pollution. EPA has fulfilled Congress's intent.
The EPA's Attainment Date Extension Policy reflects the Clean Air Act provisions. EPA understands that attainment for upwind areas is not as easy as it would be for them to do so as quickly as they wish. EPA has extended the attainment deadlines to upwind areas in an effort to achieve this goal. It also restricted the NOX submission extension to areas where there are documented transport issues. If an upwind zone fails to reach its goal, it might be required to implement more stringent controls.
EPA had no authority to assign responsibility for transport until 1998. However, by that time, EPA had a sufficient understanding of the magnitude and scope of the transport pollution problem. EPA still couldn't get adequate redress due to transported pollution after the OTAG process had been completed. EPA interpreted the Clean Air Act section 181(a), in light its own understanding of the problem of transport pollution.
As stated in EPA's Attainment Polic and Guidance (EPA), the EPA's policy assumes pollutant transport is an essential part of the area's attainment. A state in the upwind cannot rely on segregation or emissions to attainment. EPA could not assess whether upwind states had taken sufficient control measures, or if they were failing to take necessary steps to reduce their own pollution, until 1998.
EPA began to understand the problem of transport pollution better in 1999. EPA had analyzed regional transport pollution and associated air pollution, and found that pollution from upwind areas was most likely to be transported to their downstream areas. The states and EPA collaborated to determine who was responsible for transport. It took several years to complete a regional transport analysis. In the summer 1999, EPA finally announced that it had been assigned transport responsibility. EPA acknowledged during this process that EPA did not have a complete understanding of how emissions are measured.
EPA has responded to commenters who questioned the EPA's Attainment date extension policy. While EPA believes the policy is consistent with Congress's intent, it has been criticized because it does not provide meaningful relief to upwind areas. EPA believes this policy should be used only as a last-resort option. EPA still believes that the graduated attainment framework is important, despite acknowledging this fact by the EPA.
Although EPA has reclassified Phoenix under section 179B as moderate, it was not intended to be a punitive action. It was actually intended to protect areas downwind from the problem of transport pollution. Section 181(a), Clean Air act directs the classification ozone nonattainment area based upon design value. During the OTAG process, EPA and the states worked together to ensure that the transportation issues were addressed.
FAQ
What's the potential for climate-change technology?
There are many technologies that can be used to tackle this global problem. We can now transition to a more sustainable tomorrow by utilizing renewable energy sources such as solar, wind and geothermal, as well energy storage systems like thermal tanks or battery packs.

Ultimately, understanding our role in carbon production is paramount allowing us all to be better stewards of our planet.
Climate change: What is it and how can it happen?
Climate change refers the long-term shifts that occur in global weather patterns due to an increase in greenhouse gasses in the atmosphere. These gases trap heat in the atmosphere, which causes global temperatures rise. This leads to many changes in weather and climate. This could lead to rising sea levels, melting glaciers and extreme storms and dry spells, widespread coral reef bleaching, and the extinction of species.
Human activity is the major cause of climate change. These activities cause the atmosphere to heat up much faster than natural processes, like volcanic eruptions. They also emit many times more carbon dioxide than volcanoes.
Another major contributor to the global greenhouse gas emission is deforestation. It accounts for around 15-20%. It releases the stored carbon dioxide into the atmosphere when trees are chopped down or burned. Furthermore, forests act like a natural carbon sink and remove CO2 from air. Without this absorption capacity carbon dioxide levels will continue rising with devastating consequences to ecosystems all over the world.
The release of CO2 into the atmosphere is not the only effect of human-caused polluting. Other harmful gasses like methane, CH4, and nitrous dioxide (N2O), are also emitted by humans. Methane has been extensively used in industrial processes and contributes greatly to atmospheric warming. Meanwhile, N2O is emitted most commonly from agricultural soil management activities. For example, fertilization or tilling can release excess nitrogen into soil which results in N2O production upon contact with microbial organisms.
To limit climate change, we must collaborate across economic, political, and social institutions in order to reduce our emissions and transition away fossil fuel dependence towards renewable energy sources. The smart solution to reduce CO2 accumulation and atmospheric pollution could be replacing polluting fossil energy sources with zero-waste solutions. Reforestation projects, which are powerful aid in the fight against climate change by absorbing large quantities of CO2 back into nature and maintaining biodiversity, can help us take responsibility for our environmental impact.
What are the roles of individuals and communities when it comes to addressing climate change?
Climate change is one our greatest contemporary challenges. It affects all of us and requires our collective attention as well as individual actions to make a real difference.
Individuals can play an important role in addressing climate change. Your everyday behaviors could include reducing waste, conscious eating, changing your lifestyle, such as becoming vegetarian, choosing sustainable clothing and decor, and using public transport more frequently. They can also take part in advocacy and support initiatives that promote sustainability in their communities.
Communities are also key players in addressing climate change on a bigger scale. They can create policies that reduce greenhouse gas emissions by encouraging electric or bicycle transport, deforestation reductions, and the promotion of composting. Collaboration between different communities across cities and countries is fundamental for achieving success in this mission.
Moreover, civic education on the threats posed by climate change, as well as on ways to contribute positively towards tackling it needs to be implemented from the early stages of education acquisition throughout lifelong learning opportunities. This will enable individuals to become more aware of the issues and better understand how we are connected with other societies that are similarly affected by global warming.
Employers bear a huge responsibility for combating climate change. It is important that they adopt sustainable corporate practices and use green alternatives wherever possible.
The collective efforts of individuals, communities and businesses will all play a significant role in addressing global warming and defending humanity from the long-term effects of climate change.
What are the causes for climate change
Climate change is a global phenomenon that has been driven by an increase in human-generated greenhouse gases emitted into our atmosphere, primarily due to fossil fuel burning for electricity and transportation. These emissions trap more sun's heat, causing global temperature rises.
Other contributing factors to climate change are population growth, land clearance and destruction of ecosystems as well as deforestation, energy use, over-grazing and energy consumption. This further reduces the number of naturally occurring carbon sinks that absorb CO2 from the atmosphere. Climate change may also be caused by natural factors such as changes to solar radiation.
This combination of human activities results in Earth exceeding its ability to balance its energy budget. The result is an average global increase of 1° Celsius since pre-industrial days. Because oceans absorb the majority of heat energy, glaciers are more likely to melt than they ever form. Other negative consequences include water scarcity, droughts and extreme weather events like flooding and hurricanes.
We must reduce our carbon footprint, and begin reducing our emissions immediately to protect ourselves from the increasing impacts of climate change. Along with reducing our dependence upon fossil fuels to generate electricity, it is important to invest in renewable sources like wind turbines or solar cells that do not emit harmful pollutants into nature. Also, reforestation is a sustainable practice that can restore balance to the delicate planetary cycles which are essential for our survival.
What are the international efforts currently being made to address climate change
The current state of international efforts to address climate change is one of unprecedented unity and momentum. Countries from all over the globe are increasingly coming together to find ways to reduce their emissions, increase resilience against impacts and invest in renewable energy.
The Paris Agreement has been a catalyst for global action. Individual countries can set voluntary targets for reducing their carbon emissions by using the framework provided by the Paris Agreement. Additionally, the UN Framework Convention on Climate Change (UNFCCC) is providing political guidance and piloting new initiatives such as carbon market mechanisms.
Progress is also being made in specific regions; for example, The European Green Deal is a comprehensive package of legislation aimed at recreating Europe's economy with sustainability at its core, while countries of the African continent have committed to the African Renewable Energy Initiative which aims to increase Africa's share of global renewable energy production.
Action can also be seen across industries and sectors. Cities are moving towards sustainable public transport, while the whole society is adopting more sustainable lifestyles. Companies are developing technologies to reduce emissions, while investors shift their capital away fossil fuels in favor of renewables.
Through the Common Reporting Framework (CFR), the 2021 Guidelines, the rich countries that are members of the OECD committee have agreed to common standards for reporting their national climate change actions.
These efforts signify a new level of importance for climate action. To meet climate goals, both governments and civil society must continue to build on the momentum.

How To
How to reduce your carbon footprint and fight climate change
There are many actions you can take in order to reduce your carbon emissions and fight climate change. First, reduce any energy you consume in your home by investing in energy-efficient appliances, lighting, and insulation. You can also reduce energy consumption by turning down your thermostat during winter and summer, unplugging electronics, using public transportation, walking instead of driving, and switching off lights when they are not in use.
Second, recycle as much material as possible. Compost food scraps rather than throwing them away. This will ensure that they don't end-up in landfills which release methane gas into our atmosphere. Third, plants trees around your house for shade and natural cooling. The air absorbs carbon dioxide through the vegetation. Finally, you can consider buying products with minimal packaging and sustainable labelings like organic cotton or FSC wood. These certifications indicate that it has been sustainably managed over a long period of time to preserve forest health.
Not only can you reduce your personal emissions but you can also support organizations like The Nature Conservancy Canada, Climate Change Solutions and Emissions Reduction Alberta.
Everyday changes can be made to help fight climate change.
