By 2020, BASF aims to reduce greenhouse gas emissions per metric ton of sales product by 25% compared with 2002. BASF’s innovative products enable our customers to contribute to climate protection. In our production we have long been striving to reduce the greenhouse gas emissions. Worldwide we are the only company that regularly publishes a comprehensive corporate carbon footprint since 2008.

4. BASF’s Corporate Carbon Footprint.
In February 2008, BASF became the first company in the world to
present a comprehensive carbon footprint which was updated in
October 2009. It covers the entire lifecycle of BASF’s products,
from sourcing of raw materials to product disposal.
