Scope 1 greenhouse gas emissions are the emissions released to the atmosphere as a direct result of an activity or series of activities at a facility level. Scope one emissions are sometimes referred to as direct emissions. Examples are:
emissions produced from manufacturing processes, such as with cement.
emissions from the burning of diesel fuel in trucks
fugitive emissions, such as methane emissions from coal mines, or
production of electricity by burning coal.
Scope one emissions are specified under the NGER legislation and must be reported.
​
Scope two greenhouse gas emissions are the emissions released to the atmosphere from the indirect consumption of an energy commodity. For example, 'indirect emissions' come from the use of electricity produced by the burning of coal in another facility.
​
Scope two emissions from one facility are part of the scope 1 emissions from another facility.
​
For example, a power station burns coal to power its generators and, in turn, creates electricity. Burning the coal causes greenhouse emissions to be emitted. These gases are attributed to the power station as scope one emissions. If the electricity is then transmitted to a car factory and used there to power its machinery and lighting, the gases emitted as a result of generating the electricity are then attributed to the factory as scope two emissions.
​
Scope two emissions are specified under the NGER legislation and must be reported.
​
Scope three greenhouse gas emissions are not reported under the NGER Scheme but can be used under Australia's National Greenhouse Accounts.
​
Scope three emissions are indirect greenhouse gas emissions other than scope 2 emissions that are generated in the wider economy. They occur as a consequence of the activities of a facility, but from sources not owned or controlled by that facility's business. Some examples are extraction and production of purchased materials, transportation of purchased fuels, use of sold products and services, and flying on a commercial airline by a person from another business.

There are several differences between biodiesel and renewable diesel, including those related to the production process, chemical composition, engine capability, cold-weather performance, and emissions. Renewable diesel is considered a superior product, despite costing a little more.
Whilst traditional biodiesels and renewable diesel come from the same feedstock, the manufacturing process differs.
PRODUCTION PROCESS AND CHEMICAL COMPOSITION
Biodiesel is a fatty acid methyl ester - FAME, produced by the transesterification, where vegetable oils or animal fats react with methanol (or ethanol) in the presence of a catalyst to form biodiesel and glycerin.
Renewable diesel is a hydrotreated vegetable oil (HVO), produced by hydrotreating. This process utilises hydrogen to remove oxygen from fats/oils, resulting in a diesel with a similar chemical structure to standard mineral diesel, enabling it to be used as a 100% drop-in replacement.
Both are more environmentally friendly than mineral diesel.
ENGINE CAPABILITY
Biodiesel is used as a blended product with mineral diesel and most commonly as B5 or B7 (5% & 7%). However, blends of B20 (20%) or greater B100 (pure biodiesel) may require the user to check with vehicle manufacturers regarding compatibility and warranty implications or consider engine modifications as it may not be compatible with all diesel engines.
Renewable diesel is a ‘drop-in fuel’ that can be used 100% in any diesel engine without modification. Fully compatible with current diesel infrastructure. Renewable diesel is much easier to use, as it can be used as a standalone fuel without needing to clean the tank after using mineral diesel.
COLD WEATHER PERFORMANCE
In addition, biodiesel generally has poorer cold flow properties than diesel; it can gel in low temperatures, while renewable diesel performs well in cold weather, similar to or better than mineral diesel.
Both fuels reduce lifecycle greenhouse gas emissions compared to mineral diesel. Biodiesel reduces CO, particulate matter, and unburned hydrocarbons, but may slightly increase NOx. Renewable diesel, on the other hand, offers more complete combustion, reducing CO, NOx, and particulates across the board.
If you want to maximise the reduction in NOx and indeed CO2 equivalents, renewable diesel is the best option and supported by OEMs.
