NZ Gaseous Biofuels GHG Carbon Intensity Methodology

This carbon footprint methodology outlines the first New Zealand specific product carbon accounting guideline for biogas and biomethane. This methodology was developed with reference to leading clean fuel standards and biomethane Renewable Energy Certificate (REC) schemes within Canada, USA and Europe. Each international scheme has its own associated methodologies as shown below in the research references and explained further in the associated research document which informed this methodology for NZ.  Appendix A contains an overview of international scheme references.
