The GHG Calculator assesses the level of reduction of GHG emissions from bio-based products such as biofuels and bioplastics against a fossil fuel baseline. The tool uses RSB's own methodology which was developed for global application by RSB members (industry, NGOs, UN organisations, universities, and farmers). The tools was designed for industry and farmers to demonstrate their level of GHG reduction for RSB certification but can be used for other applications. It is compatible with the EU Renewable Energy Directive.
