Date: November 8, 2016 Source: University of North Carolina at Chapel Hill Where the world emits is more important than how much it emits, suggesting that the southward shift of emissions toward the equator is driving the increase in total ozone. Since the 1980s, air pollution has increased worldwide, but it has increased at a much faster pace in regions close to the equator. A global emissions map is creating more total ozone worldwide compared to the amount of pollution being emitted, signaling an effect that could be difficult to reign in without strategic policy planning. Even if there is a net reduction in global emissions, ozone levels may not decrease if emissions continue to shift toward the equator. This new discovery impacts the science community dramatically because it is not all about on how much pollution is released, the more important factor is where it's released. Those with the fastest growth of emissions, such as decreasing emissions of ozone precursors in regions close to the equator are a lot more effective. Making new regulations around these areas will have a much better impact on global Ozone. Continuing observations of ozone across the tropics monitoring the situation and making model forecasts can guide decision making for controlling global ozone pollution.
