The measurement of greenhouse gas emissions associated with the entire lifecycle of a biofuel, expressed as grams of carbon dioxide equivalent per megajoule of energy (gCO2e/MJ), is crucial. This analysis encompasses all stages, starting from feedstock cultivation or sourcing, through processing and conversion, to transportation and final utilization. The result provides a comprehensive understanding of the biofuel’s environmental footprint.
Determining the emissions associated with a biofuel is fundamental for assessing its potential to mitigate climate change. It allows for a direct comparison with conventional fossil fuels, enabling informed decisions regarding energy policy and investment. Historically, the drive to calculate these emissions stemmed from a need to quantify the sustainability of alternative fuels and ensure their real-world benefits are realized.
