The United Nations Framework Convention on Climate Change (UNFCCC) met in Kyoto Japan to develop an international accord that would help mitigate the effects of climate change through the reduction of GHG emissions.
The resulting agreement called the Kyoto Protocol was signed by Canada on April 29, 1998 and ratified in 2002. It became legally binding on February 16, 2005. Under the terms of the Protocol, Canada is required to reduce emissions to a level of 6% below 1990 levels in the period 2008-2012.
As an interim step towards reporting under the Kyoto Protocol, Canada is currently required to submit annually a National Inventory Report (NIR) and a set of tables in a common reporting format for 1990 and all subsequent years to the UNFCCC Secretariat on April 15th each year. These submissions follow a set of internationally agreed to guidelines developed by the Intergovernmental Panel on Climate Change (IPCC) for the preparation of national greenhouse gas inventories.
