The nature of the pollutant plays a very important role when policy-makers decide which framework should be used to control pollution.
CO2 acts globally, thus its impact on the environment is generally similar wherever in the globe it is released.9L0-509 So the location of the originator of the emissions does not really matter from an environmental standpoint.
The policy framework should be different for regional pollutants(e.g. SO2 and NOX, and also Mercury) because the 9L0-402 study guide impact exerted by these pollutants may not be the same in all locations. The same amount of a regional pollutant can exert a very high impact in some locations and a low impact in other locations, so it does actually matter where the pollutant is released. This is known as the 'Hot Spot' problem.
A Lagrange framework is commonly used to determine the least cost of achieving an objective, in this case the total 9L0-402 reduction in emissions required in a year. In some cases it is possible to use the Lagrange optimization framework to determine the required reductions for each country (based on their MAC) so that the total cost of reduction is minimized.9L0-509 audio exam In such a scenario, the Lagrange Multiplier represents the market allowance price of a pollutant, such as the current market allowance price of emissions in Europe and the USA
