The Ultimate Green Rating
Weighted Attributes Score - Pataua North Boat Ramp
This is the weighted attributes score for the Pataua North Boat Ramp. The nature of the project is very clear on the public record, its community profile and public use is high, so its Project Description score was 15/15. The ESG Suite required for the activity is mandated by New Zealand Resource Management law, and goes through a public review process, scoring 50/50. The owner of the facility is a public authority - the Whangarei District Council. Council staff and contractors are well known for their expertise in environmental science and marine engineering, scoring 15/15. Monitoring is part of scheduled works maintenance, but monitoring reports have to be requested from Council, scoring 3/5. Transparency is high, with key information available on the public record, but some searching is required in Council records to locate it, scoring 10/15. Total Green Rating Score 93/100. Our independent Green Rating of this development is GGG™: Triple G = Excellent.

Example Rating - Pataua North Boat Ramp GGG ("Triple G" = Excellent)
The Pataua North Boat Ramp is an excellent example of a small local authority maritime servicing project that has been sensitively designed and carefully constructed to make the most of a high profile public amenity on a beautiful coastline. Notice that the seagull roost to the right of the boat ramp remains undisturbed. During our inspection, we observed that a historical stormwater problem appeared solved, and water quality around the boat ramp was high.
Weighted Attributes Scoring
A Weighted Attributes scoring system is a method widely used to compare different project, product, system, or bidding proposals where a large number of factors can affect the result. Certain key criteria critical to the project being assessed are listed, and they are weighted with a mathematical score that reflects the importance of each assessment criteria. A weighted score of 'X' out of 100 presents a convenient and easily understood assessment protocol.
As independent science-based assessors, we offer independent Green Ratings using five rating criteria: Project Description, Environmental and Social Governance criteria (ESG Suite) customised for the activity, Suitably Qualified Persons (from appropriate technical disciplines make the claim on behalf of the applicant), Monitoring and Transparency.
The ESG Suite is weighted at 50%, because they are by far the most important factors in "green assurance". Project Description is weighted at 15%, clarity and completeness needed. Suitably Qualified Persons for integrity of assurance is weighted at 15%, and Monitoring weighted at 5%, because sustainability is a long game and monitoring systems are often inadequate or missing. Finally, Transparency is weighted at 15%, it being the characteristic that generates the most public complaint about inadequate disclosure.
A Green Rating by GreenXperts is an indicator that an activity is "planet-worthy". We use a four point green rating scale of G, GG, GGG, and F to verify green claims made by organisations, products, services and programmes.
Each application for a green rating is put through our "green filter" to determine what rating it should be awarded: "Triple G" Excellent, or "Double G" Very Good, or "Single G" Adequate, or F "FAIL" insufficient or false disclosure.
Our Weighted Attributes Scoring protocol is the "green filter" that we use to assign the Green Rating score. See the Pataua North Boat Ramp below as an example from New Zealand. More detailed information is in our Summary.
