These figures do not include emissions from the manufacturing of motor vehicles or other transport equipment – this is included in the previous point ‘Energy use in Industry’. This includes a small amount of electricity (indirect emissions) as well as all direct emissions from burning fossil fuels to power transport activities. Other industry (10.6%): energy-related emissions from manufacturing in other industries including mining and quarrying, construction, textiles, wood products, and transport equipment (such as car manufacturing). Machinery (0.5%): energy-related emissions from the production of machinery. Paper & pulp (0.6%): energy-related emissions from the conversion of wood into paper and pulp. The manufacturing of these metals requires energy which results in emissions. Non-ferrous metals: 0.7%: Non-ferrous metals are metals which contain very little iron: this includes aluminium, copper, lead, nickel, tin, titanium and zinc, and alloys such as brass. Iron and Steel (7.2%): energy-related emissions from the manufacturing of iron and steel.Ĭhemical & petrochemical (3.6%): energy-related emissions from the manufacturing of fertilizers, pharmaceuticals, refrigerants, oil and gas extraction, etc.įood and tobacco (1%): energy-related emissions from the manufacturing of tobacco products and food processing (the conversion of raw agricultural products into their final products, such as the conversion of wheat into bread). Energy (electricity, heat and transport): 73.2% Energy use in industry: 24.2% Let’s walk through each of the sectors and sub-sectors in the pie chart, one-by-one. These descriptions are based on explanations provided in the IPCC’s Fifth Assessment Report AR5) and a methodology paper published by the World Resources Institute. To know what’s included in each sector category, I provide a short description of each. The overall picture you see from this diagram is that almost three-quarters of emissions come from energy use almost one-fifth from agriculture and land use and the remaining 8% from industry and waste. 2 This is the latest breakdown of global emissions by sector, published by Climate Watch and the World Resources Institute.

In this post I present only one chart, but it is an important one – it shows the breakdown of global greenhouse gas emissions in 2016. To figure out how we can most effectively reduce emissions and what emissions can and can’t be eliminated with current technologies, we need to first understand where our emissions come from.

The world emits around 50 billion tonnes of greenhouse gases each year. To prevent severe climate change we need to rapidly reduce global greenhouse gas emissions.
