Annual inventories of greenhouse gas (GHG) emissions are carried out in all Odebrecht Businesses where emissions are significant (99% of the total). In line with GHG Protocol guidelines, the indicators are consolidated and monitored by the Holding Company. Goals for improvements in GHG emissions management are part of the Action Programs and monitoring programs conducted by corporate sustainability teams. The most significant emissions arise from Braskem’s operations, which correspond to 84.9% of the total.

Consolidated emissions in 2015 for all Businesses amounted to 34.5 million tons of carbon equivalent (tCO2e). Of that total, 35.2% is related to direct issues under the control of each Business, representing a specific emission of 0.08 grams of carbon equivalent (gCO2e) per Brazilian real in gross revenue.

Braskem focuses its efforts on the diversification of basic raw materials with the aim of progressively reducing the level of emissions. The company, which is a leader in the production of biopolymers (Green Plastic) made from sugarcane, has been progressively increasing the consumption of natural gas, a fuel that is less intensive in GHG emissions compared to naphtha. Considering the absolute differences in real emissions between 2009 and 2015 compared to base year 2008, emissions of 5.3 million tCO2e were avoided, equivalent to the planting of 35 million trees.

At Odebrecht Agroindustrial, the production process for ethanol, sugar and biomass electricity captures more greenhouse gases than it emits. In addition, sugarcane cultivation in areas previously used for pasture brings balance and increases the carbon capture process, further contributing to the removal of CO2 from the atmosphere. During the 2015-2016 harvest, net mitigation was 6.0 million tCO2e, 54% above the previous period, justified by the increase in production, since the large volume of emissions avoided derives from the use of ethanol as fuel and surplus electricity. The net effect is equivalent to 39 million trees planted.

At Odebrecht Ambiental, since 2012 there has been an almost proportional increase in emissions from the company’s three segments (Water & Sewer, Utilities and Waste), the outcome of the physical growth of the business, with new units reporting their data. Saneatins and Recife - the two largest units - began reporting respectively in 2013 and 2014, when they came under the management of Odebrecht Ambiental. At Odebrecht Engineering & Construction, which includes the operations of Construtora Norberto Odebrecht in Brazil, an emission reduction target of 25% by 2020 was established in relation to the base year 2010 (year the first inventory was carried out), considering the sum of scopes 1 (direct emissions) and 2 (indirect emissions per energy acquisition) divided by gross revenue (g CO2e/BRL). The proposed target for 2020 was achieved for the first time in 2014.

1 - Includes CO2, CH4 and N2O gases
2 - Biogenic emissions arising from changes in soil use. Biogenic emissions are related to the CO2 absorbed from the atmosphere by the plant during the process of photosynthesis, and are therefore considered neutral and calculated separately. In the case of Odebrecht Agroindustrial, they are caused by burning sugarcane bagasse.

(1) Land-Use Change (LUC): Emissions derived from land-use change (change in soil and above-ground carbon stocks) at Odebrecht Agroindustrial
result in increased carbon sequestration, leading to greater net mitigation. The LUC estimates are somewhat uncertain due to the lack of carbon stocks in equilibrium in the soil. The calculation method considered IPCC Tier 1 default factors and was improved with more recent and regional data from the Harmonized World Soil Database (HWSD).
(2) The Brazilian GHG Protocol Program does not adopt the concept of net GHG emissions, but directs organizations conducting inventories to report emissions and removals separately.
