CSA major source of CO2 emissions in Rio de Janeiro


SBB 14 November Companhia Siderúrgica do Atlântico (CSA) – the new Brazilian slab plant owned by ThyssenKrupp and Vale – is being blamed for a large rise in carbon emissions in Rio de Janeiro, Steel Business Briefing learns from local environmental authorities.

From June 2010 to June 2011, city chiefs estimate 5.7m tonnes of CO2 were released into the atmosphere by CSA’s activities, half the city’s total 11.35m t of CO2 emissions in 2005.

Rio de Janeiro aims to reduce CO2 emissions 8% (from 2005’s CO2 total) by 2012 and the policy on climate change and sustainable development requires emissions to be cut 16% in 2016 and 20% by 2020.

Authorities have yet to decide whether to penalize CSA or if the company can receive its definitive operating license. To date, the mill has functioned with a pre-operation license that expires in September 2012, SBB notes.
