This 2017 report by the Stockholm Environment Institute (SEI) assesses the life-cycle carbon footprint of a proposed wood biorefinery in Estonia. The study concludes that the facility would be climate-neutral and would positively contribute to Estonia's climate goals by replacing oil shale electricity with renewable energy and sequestering biogenic carbon in products.

• The proposed biorefinery is estimated to have a production capacity of approximately 750,000 tonnes per year, requiring about 3.3 million cubic metres of wood annually. The investment is projected to be around one billion euros.
• The facility's fossil carbon footprint is calculated to be negative, at -0.39 tonnes of fossil CO2-e per tonne of finished product (cellulose). This is primarily because the renewable electricity exported to the grid offsets fossil-fuel-based power.
• The biorefinery would generate 682 GWh/a of electricity from biomass (black liquor, bark, and sludge). While 63% (427 GWh/a) is used internally, 37% (255 GWh/a) is supplied to the grid, replacing oil shale electricity.
• In terms of biogenic carbon, the plant would sequester an average of 1.3 tonnes of biogenic CO2-e per tonne of finished product, after accounting for the 0.33 tonnes of biogenic CO2-e emitted during renewable energy production.
• Compared to a 'null scenario' where the plant does not exist and wood is exported, the proposed facility would reduce fossil CO2 emissions by approximately 5% due to lower transport emissions and the displacement of oil shale power.
• The project is expected to support Estonia's climate targets by increasing the share of renewable electricity in total consumption by 8 percentage points, potentially raising it to 26%.
