Carbon dioxide emissions
In 2017, the NSG Group was responsible for emitting 3.7m tonnes of CO2. This is a 5 percent reduction on the previous year. Our Scope 1 emissions from our furnaces and fuel were 2.9m tonnes. Our measured Scope 2 indirect emissions were 0.9m tonnes of CO2 and our estimated Scope 3 emissions were 0.9m tonnes. Conversion from heavy oil to natural gas has helped our float plants reduce carbon emissions by around 50 percent over the past 40 years and a combination of design and operational innovations has made further progress. We aim to reduce CO2 emissions per tonne of equivalent product by 1 percent per year until 2020. This target has been achieved year-on-year for the last three years. We are currently investigating the requirement for setting a science based carbon reduction target.
