Greenhouse gases Agreement

The reflection principle approach (see article by Jost in this issue) produces essentially perfect agreement with experiment but it is not able to provide vibrational structure. Therefore the time-dependent techniques are important for indirect photodissociation, of which there are many examples in atmospheric chemistry, including HCHO, SO2, NO2,02, CO, HCl, H2O and O3. Many studies have shown how isotopic analysis is able to provide valuable insight concerning atmospheric photochemical reactions, and emissions sources and loss mechanisms. One of the largest uncertainties in projections of future climate is the ability to predict greenhouse gas concentrations, which depend on accurate knowledge of their sources, sinks and atmospheric photochemistry. 

In this context, pressures to implement greenhouse gas (GHG) mitigation measures have had a top-down character in that they originated from international agreements, the Kyoto Protocol, and the EU Directive on Emissions Trading. 

The quicker the climate warms up, the more likely it is that feedback processes will change the greenhouse gas buildup. There is a widespread agreement that C02 and other trace greenhouse gases may double sometime within the next century. 

Under the Kyoto Protocol, the EU has agreed to an 8% reduction in its greenhouse gas emissions by 2008-2012, compared to the base year 1990. The reductions for each of the EU-15 countries have been agreed under the so-called EU Burden sharing agreement, which allows some countries to increase emissions, provided these are offset by reductions in other Member States.

Basics of environmental rulemaking is reviewed as well as the role of the states. An overview Part 70, Title V permitting is provided, what various Title V permits exist today, why permit variations occur and when a state should be notified about work on a permitted process. Greenhouse gas requirement are in place today at the Federal level and at the state level one state has set hmits and requirements for controls but various agreements foretell expansion of such rulemaking to other jurisdictions.

As of 2011,191 states have signed Kyoto Protocol, which is a legally binding international agreement to reduce greenhouse-gas emissions by 5.2 percent of 1990 levels by the year 2012.
