the week in which the World Environment Day is celebrated, Braskem has great news about its environmental performance. Since 2007, when it started measuring its greenhouse effect emissions, the company reduced by 13.6% this type of environmental aspect, reaching 7.3 million tons of CO2 equivalent in 2009. The information is included in the company’s 3rd greenhouse effect inventory, which was just concluded. The result was reached thanks to the investments in energetic efficiency, to the discontinuity of some operations that were intensive in emissions and the other operational improvements.

With this evolution, Braskem took another important step in the strategy of performing in consonance with sustainable development and advanced in the fulfillment of the public commitment "You must mature to be green", which it disclosed in 2009, where it committed to, among other things, to reduce the intensity of greenhouse effect gas emissions. The index truly cut the CO2 equivalent 0.80 per ton of the product in 2007 to 0.71 in 2009.

All the eco-efficiency indicators, which presented the emissions and consumptions per ton of production, also improved expressively between 2002 and 2009. The generation of residues dropped 61%, of waste waters 40%, water consumption 19% and energy, 12%.

Upon being compared with the sector average in Brazil or around the world, Braskem's differential is evident: its consumption of 4 cubic meters per ton of the product is significantly lower than the chemical industry average around the world, which is 27.8, according to data from ICCA - International Council of Chemical Association. Braskem generated 2.7 kg of residue per ton of the product, while the Chemical Industry average in Brazil is 11.9, according to data from Abiquim - Associação Brasileira da Indústria Química [Brazilian Chemical Industry Association].

In 2002, when Braskem was formed, there was the understanding that the company should focus on the reduction of the environmental impact. And exactly that was done. The company went from an average level of investments in improvements in the installations in health, security and environment of R$ 40 million, between 2003 and

2004, to R$ 140 million between 2005 and 2008. This was linked to the improvement of the practices and management as a whole. When Braskem got past the strategic integration phase, there was growth in the investment in Health, Security and Environment in 2009 to another level, when almost R$ 290 million invested.

Recently, Braskem launched, in Bahia, a new product that partially uses renewable raw material: ETBE. The company also developed and certified, as pioneers in the world, the Green Polyethylene which has the main raw material, ethylene, will be produced 100% from renewable raw material: ethanol. The industrial factory which will produce the Green Ethylene will start to operate in the third quarter of this year, in the Triunfo pole, in Rio Grande do Sul. It will be the first industrial scale one in the world and will produce 200 thousand tons/year.

The use of renewable raw material, originated from sugarcane, for the production of Green Polyethylene brings a very important benefit: its contribution for the reduction of greenhouse effect gases. The carbons that participate in its composition comes from carbon gas dispersed in the atmosphere. Each ton of Green Polyethylene is equivalent to the removal of 2.5 tons of CO2. Each year, with the production of ETBE and Green Polyethylene, Braskem will be contributing with the emission reduction of more than 750 thousand tons of CO2. That is equivalent to planting and maintaining more than one million trees each year.
