While discussions are ongoing in Paris to achieve a legally binding and universal agreement on climate, with the aim of keeping global warming below 2°C, the Italian National Environmental Protection Agency published the yearly report on national green house gasses emissions.

Total greenhouse gas emissions, in CO2 equivalent, excluding emissions and removals from land use, land use change and forestry, decreased by 16.1% between 1990 and 2013 (from 521 to 467 millions of CO2 equivalent tons). The share of the different sectors, in terms of total emissions, remains nearly unvaried over the period 1990- 2013. Specifically for the year 2013, the greatest part of the total greenhouse gas emissions is to be attributed to the energy sector, with a percentage of 81.7%, followed by industrial processes and agriculture, accounting for 7% of total emissions, respectively, and waste contributing with 4.2%.

The most important greenhouse gas, CO2, which accounted for 82.4% of total emissions in CO2 equivalent in 2013, showed a decrease by 17.4% between 1990 and 2013. In the energy sector, specifically, CO2 emissions in 2012 reduced of 15.4% as compared those in 1990.

For the agriculture sector, the trend of GHGs from 1990 to 2013 shows a decrease of 14.9%, due to the reduction of the activity, such as the number of animals and cultivated surface/crop production, and the recovery of biogas from manure and agricultural residues, leading to a large reduction of CH4 emissions. CH4 emissions, in 2013, are mainly originated from the agriculture sector which accounts for 42.4% of total methane emissions, as well as from the waste (37.5%) and energy (20.1%) sectors.

For the waste sector, total emissions, in CO2 equivalent, decreased by 20.5% from 1990 to 2013, mainly due to a decrease in the emissions from solid waste disposal on land (-23.6%), which account for 75.0% of waste emissions. In the waste sector, CH4 and N2O emissions were equal to 10.1% and 4.4%, respectively, of the total CO2 equivalent greenhouse gas emissions in 2013. Both gases showed a decrease from 1990 to 2013, equal to 18.3% and 29.6% for CH4 and N2O, respectively.
