The Clean Air Act provides legal mechanisms to address the transport pollution problem. However, Congress didn't explicitly give States the authority to act according their own deadlines. EPA developed a policy in order to end the tension between deadlines. This policy is designed to allow upwind regions to accept responsibility for pollution. In doing so, EPA is fulfilling 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 therefore extended the attainment deadlines in upwind areas. It has also restricted the NOX submission extension for areas with documented transport difficulties. If an area upwind fails to achieve its goals, it may need to exercise more stringent control.
EPA could not assign transport responsibility until 1998. EPA had a good understanding of the scope and magnitude of the transport polluting problem at that point. EPA failed to receive adequate redress until the OTAG process. EPA interpreted the Clean Air Act section 181(a), in light its own understanding of the problem of transport pollution.
As stated in the EPA's Attainment Policy and Guidance, the EPA's policy assumes that the transport of pollutant is an integral part of the area's nonattainment. This assumption means that an upwind state cannot depend on segregation to achieve its goals. 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 and determined the source of the pollution in the region and its impact on the air quality. It had also found that the pollution was being transported from the upwind to the downwind. The transport responsibilities were determined by the EPA and the state governments. The initial regional transport analysis took over a decade to complete. In 1999, EPA officially announced the transfer of transport responsibility. EPA also acknowledged that EPA had not developed a comprehensive approach to measuring emissions due to a lack in understanding.
EPA has responded to commenters who questioned the EPA's Attainment date extension policy. Although EPA believes the policy conforms with Congress's intent, critics have pointed out that it does not provide meaningful relief for upwind regions. EPA believes that this policy should not be used except as a last resort. Despite acknowledging the importance of the graduated attainment structure, EPA has not changed the stance on the reclassification provision.
Although EPA has reclassified Phoenix under section 179B as moderate, it was not intended to be a punitive action. It was intended to protect downstream areas from the effects of transport pollution. Section 181(a), Clean Air act, specifies that ozone nonattainment zones are to be classified based upon design values. During the OTAG process, EPA and the states worked together to ensure that the transportation issues were addressed.
FAQ
What is the climate impact of land use and deforestation?
The climate is directly affected when land use and deforestation are both occurring. If trees are cut down, or burned, carbon dioxide, one the most important greenhouse gases, is no longer absorbed. Therefore, when trees are cleared by deforestation or burned for agricultural purposes, less carbon dioxide is removed from the atmosphere.
Changes in land usage can also cause more greenhouse gasses to be released into the atmosphere. When forests are cleared for livestock production, the use of fertilizer and pesticides may lead to an increase in methane or nitrous oxide emissions. Clearance can increase exposure of soils that have large amounts stored carbon. These soils release carbon dioxide when they are turned over or disturbed through farming activities.
The impacts of deforestation and land-use change extend beyond just increased greenhouse gas emissions; it can also have an impact on regional air quality. Smoke from deforestation-related burning events has been shown to cause decreased visibility and health problems such as asthma, as well as other respiratory conditions. Because of the reduced amount of aerosol particles in our atmosphere, which scatter sunlight off the Earth's surface, these changes can have a cumulative impact on global climate.
In conclusion, deforestation and land-use change have resulted in a significant contribution to increased levels of global greenhouse gas emissions and have had negative impacts on local air quality that further contribute to climate change. If serious efforts towards mitigating climate changes are to be made quickly, then reducing these practices must be a priority.
How are developing countries and communities affected by climate change?
Because of their limited access and lack of technology and healthcare, the impact climate change has on developing countries and communities is particularly severe. Climate change can increase the pressure on already limited resources. Floods and droughts can also cause damage to already fragile ecosystems. Rising temperatures can lead to a decrease in crop yields, which will disproportionately affect poorer communities struggling with food insecurity. Extreme weather events like heatwaves or hurricanes can lead to destruction of infrastructure, displacement of people and further perpetuating economic inequality.
The long-term impacts of climate change include resource scarcity, poverty, increased health risks, and an increase of vector-borne diseases, such as malaria and dengue fever. A rising sea level and extreme weather events will increase the risk of flooding, putting lives at stake in coastal areas that often lack the infrastructure or emergency services required to evacuate. Not only does it require reducing greenhouse gas emissions, but other measures like better management and access to medical facilities. This will help with the prevention of diseases like Malaria.
What's the current climate in the world? And how does it change?
The current climate situation is one of uncertainty and unprecedented change. Temperatures are increasing dramatically due to increased atmospheric carbon dioxide, which is leading to heat waves, droughts and changes in rainfall patterns.
These changes already have a profound effect on ecosystems all over the globe, causing habitat destruction and extinctions. They are also threatening lives and livelihoods for billions of people, especially those who live in areas with resource scarcity.
Because of the increase in average surface temperatures from human activity, the number of extreme weather phenomena such as hurricanes and cyclones has been increasing steadily over time. As temperatures rise, this trend will likely continue.
A rapidly changing climate has many effects. They can impact everything from food insecurity to displacement by extreme weather events to sea level rise, causing communities to relocate. Climate change is also exacerbating existing social inequalities by disproportionately affecting marginalized communities that do not possess the resources or knowledge necessary for adapting effectively.
Although there have been some progress in efforts to reduce carbon emissions and renewable energy initiatives in certain countries, it is still not clear that meaningful global action is required to mitigate these changes. All nations must unite to prevent further destruction and devastation by climate change.

How To
How to Invest in Clean Energy and Support the Transition to a Low-Carbon Future
Clean energy is any form of renewable energy that doesn't produce or emit pollution. It includes technologies such as solar photovoltaic, wind power, hydroelectricity, geothermal energy, and hydrogen fuel cells. Clean energy investments can provide many environmental benefits. They reduce dependence on fossil fuels and help to reduce air pollution.
By buying shares in companies involved in developing clean energy technologies, investors can get involved in these projects. This could be done by investing in publically traded stock, mutual funds, or ETFs related to renewable energies. Investors might also consider direct investments in start-ups or venture funds to finance research and development for clean technology technologies.
Clean energy investors are supporting innovation that helps to reduce harmful emissions from conventional sources of electricity generation. This investment may also lead to increased economic development by creating jobs related to the production of renewable energy systems that require skilled labor and engineers. Finally, putting money into clean energy can provide investors with a financial return due to tax incentives programs that are incentivizing investments into green technologies like wind farms, solar panels, and biomass heat generation systems.
By investing in companies focused on creating cleaner sources of electricity from renewable resources such as sun, wind, and water while avoiding activities that could harm the environment, we can support the transition to a low-carbon future while reaping economic rewards at the same time.
