Editing Kyoto Protocol (section)

===Monitoring emissions===
Monitoring emissions in international agreements is tough as in international law, there is no police power, creating the incentive for states to find 'ways around' monitoring. The Kyoto Protocol regulated six sinks and sources of Gases. Carbon dioxide, Methane, Nirous oxide, Hydroflurocarbons, Sulfur hexafluouride and Perfluorocarbons. Monitoring these gases can become quite a challenge. Methane can be monitored and measured from irrigated rice fields and can be measured by the seedling growing up to harvest. Future implications state that this can be affected by more cost effective ways to control emissions as changes in types of fertilizer can reduce emissions by 50%. In addition to this, many countries are unable to monitor certain ways of carbon absorption through trees and soils to an accurate level.<ref>Victor, David G.
