Understand the most frequently used terms and phrases when discussing Greenhouse Gas emissions and liquid fuels.
Greenhouse gasses
Greenhouse gases constitute a group of 7 gases contributing to global warming and climate change; carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3). Converting them to carbon dioxide (or CO2) equivalents makes it possible to compare them and to determine their individual and total contributions to global warming.
CO2 equivalent
CO2 equivalent is a metric measure used to compare the emissions from various greenhouse gases on the basis of their global-warming potential (GWP),iv by converting amounts of other gases to the equivalent amount of carbon dioxide with the same global warming potential. For example, the GWP for methane is 25 and for nitrous oxide 298.
Carbon Intensity
Carbon Intensity (CI) means the amount of lifecycle greenhouse gas emissions per unit of energy of fuel. Carbon intensity is expressed in CO2 equivalent per MJ, g CO2eq/MJ.
The GHG emissions savings that HVO provide are expressed in ‘carbon intensity’, CO2 equivalent per MJ (CO2eq/MJ) on the independent International Sustainability Carbon Certificate(ISCC) for GHG reporting purposes.
Carbon cycle
Carbon cycle describes how carbon transfers between different reservoirs located on Earth. This cycle is important for maintaining a stable climate and carbon balance on earth.
Carbon neutrality
Carbon neutrality, put simply, means that we are not adding new emissions to the atmosphere. Emissions will continue, but will be balanced by absorbing an equivalent amount from the atmosphere.
