A low-carbon production

Vallourec examines its carbon policy.

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Vallourec examines its carbon policy in the context of the Paris Conference of Parties (COP​21)​​, a crucial meeting on the climate organized by the UN*.



Vallourec produces ​low greenhouse gases in comparison to other similarly sized industrial groups

Two main factors explain this low level of emissions:
  • ​More than 75% of the steel the Group produced in 2014 was made from recycled scrap metal.
  • In its Brazilian factories, Vallourec uses charcoal instead of coke. Therefore the cast iron production process in our blast furnaces releases CO2. But the charcoal used is made from eucalyptus trees grown by Vallourec, which absorb an even larger​​ ​amount of CO2 as they grow​.
  • Recently a detailed scientific study has been conducted over several years, with the assistance of Brazilian experts and universities, and under the aegis of the French national forestry office. It showed that the forest-steelworks system captured close to 250,000 tons of greenhouse gases per year during the last 30 years, instead of, as previously thought, emitting greenhouse gases.
     
The main emissions of CO2 in Vallourec's production processes come from the natural gas burnt for the rolling and heat treatment of tubes.
 
The reduction of greenhouse gases is one of Vallourec's commitments

In relation to Vallourec's ​direct emissions, the ratio of 231 kg of CO2 per metric ton processed has remained stable since 2010. This is in spite of the increase in the number of tubes heat treated - a result of the increase in Vallourec's product quality. The same goes for the ratio of emissions to consolidated revenue, which was 220 g of CO2 per euro in 2014.
 
In the beginning of 2016, the Group will set and publish its emissions objectivesfor the coming years based on its new industrial footprint, given the assessment of Brazilian operations mentioned above. Progress in the area of emissions will continue with Vallourec's energy efficiency plan (GreenHouse project), and in particular with the eco-design approach applied to processes. Vallourec will also improve performance through the responsible management of its Brazilian forest, from which even surplus biomass is expected.
 

 
*From November 30 to December 11, 2015​, 195 member states of the United Nations Framework Convention on Climate Change meet at the Paris Conference of Parties (COP21). The convention was signed in 1992 and aims to reach an international agreement on how climate change can be limited to an increase of 2°C by 2100.
