What are the sources of greenhouse gas emissions?

 

A ranking of the sources of greenhouse gas emissions established for our world in data for the year 2016 shows the diversity of the sectors concerned and alerts us to the difficulty of finding a rapid and appropriate response to each of the sources of pollution identified.

Energy consumption: 73.2%, of which

Energy used for industry: 24.2%, such as for iron and steel, petrochemicals, mining, textiles, food processing, ……

Road transport: 11.9%,

Energy used for residential buildings: 10.9

Energy used for commercial buildings: 6.6%,

Air transportation: 1.9%,

Marine transportation: 1.7%,

Agriculture and land use: 18.4%, of which

Livestock and manure use: 5.8

Maintenance of agricultural soils: 4.1

Deforestation: 2.2

Industrial processes: 5.2%, such as cement and chemical processes

Waste: 3.2%, including wastewater and landfills

 

In the industrial sector in particular, efforts to reduce greenhouse gas emissions must be combined with an increase in the production of clean energy, the energy efficiency of buildings and the way vehicles are driven, for example. But changing practices alone is not enough, it is also necessary to rely on technological innovations, which for certain sectors such as maritime or air transport, are not yet available on a large scale.




These data confirm those proposed in 2014 by the IPCC on polluting activities with an almost identical distribution:

Heat and electricity production: 35% of which fuel extraction, refining, processing and transport

Agriculture and land use: 24%.

Industry: 21%; and

Transport: 14% of the total

Buildings excluding electricity consumption: 6%.
 



 

The IPCC also had another classification relating to greenhouse gases emitted by human activities which is characterized as follows

Carbon dioxide, CO2: 76% of which fossil fuel combustion for 65% and forestry activities including deforestation and clearing of agricultural land for 11%.

Methane, CH4: 16% of which agricultural activities, waste management, energy consumption and biomass production

Nitrous oxide, N2O: 6% of which fertilizer and fossil fuel use

Fluorinated gases: 2% including refrigeration and various industrial and consumer processes that use hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).
