+## Discussions
+1. Different standard rating programs call for different rating scope, calculation, and algorithm, etc. Some represent the ratings using number scores (e.g. EnergyStar), some using alphabetic letters (NutriScore). Therefore, in order for SCER to be widely adopted, and be flexible enough to fit a wide range of use case scenarios, the design of the SCER spec shall adopt the generic and modular approach for standardization, and enable domain experts from different industry verticals to define category-specific SCER standard, based on the generic SCER spec.
+2. SCI addressed the score part, but lacking **relative rating specification**. Therefore, SCER is supplementing SCI spec to provide an easy-to-understand rating mechanism. SCER also defines the standard specification for software categorization, benchmark definition, and rating definition. These are used as guidelines for users of SCER spec to create their own category-specific SCER specifications.
+2. With respect to the use of SCER spec, it involves data collection and publication of the ratings for various types or categories of software. For instance, refer to [MLPerf](https://mlcommons.org/) and [Geekbench](https://www.geekbench.com/), both of which defined a standard set of workload, in the case of MLPerf, the workload is open sourced, in the case of Geekbench, the workload is close sourced. Both of them provide a standard set of workload and benchmarks. They also provide a means of data collection and intuitive result publication. What are the directions of SCER in this respect? Do we want to define the spec so that other people can use it to define their own category specific SCER spec, or do we create a SCER plaform that's more like MLPerf or Geekbench where benchmarks and data collection of workload are crowd-sourced, and the results are published on a central SCER platform?
+1. House-keeping item: Confirming CLA (Contributor License Agreements) handling: 
+    - GitHub Integration: There are tools like CLA assistant that integrate with GitHub to manage CLA confirmations. When a contributor submits a pull request, they are prompted to agree to the CLA with a single click if they haven't done so already for that project.
+    - Git Signed-off-by Statement: In certain projects, especially those using Git, a contributor might use the signed-off-by statement in their commits as an indication that they agree to the terms of the CLA, though this method is less formal and typically used in conjunction with another method.

+This References section demonstrates cases where different rating, labelling systems are used for different use cases and industry verticals.
+
+### EnergyStar:
+
+To earn the ENERGY STAR, eligible commercial buildings must earn an 1–100 ENERGY STAR score of 75 or higher—indicating that they operate more efficiently than at least 75% of similar buildings nationwide. Before applying, a building's application must be verified by a Professional Engineer or Registered Architect.

+
+
+### Nutri-Score:
+Nutri-Score is a front-of-package nutritional label that converts the nutritional value of food and beverages into a simple overall score. It is based on a scale of five colors and letters: 
+- A: Green to represent the best nutritional quality
+- B: Light green, meaning it's still a favorable choice
+- C: Yellow, a balanced choice
+- D: Orange, less favorable
+- E: Dark orange to show it is the lowest
+
+The Nutri-Score calculation pinpoints the nutritional value of a product based on the ingredients. It takes into account both positive points (fiber content, protein, vegetables, fruit, and nuts) and negative points (kilojoules, fat, saturated fatty acids, sugar, and salt). 
+
+The Nutri-Score is calculated per 100g or 100ml. The goal of the Nutri-Score is to influence consumers at the point of purchase to choose food products with a better nutritional profile, and to incentivize food manufacturers to improve the nutritional quality of their products.
+

+
+### CDP:
+[CDP](https://www.cdp.net/en/info/about-us) (formerly Carbon Disclosure Project): A global disclosure system for companies, cities, states, and regions to manage their environmental impacts.
+- Data collection as a form of company disclosure: CDP provides guide that covers the key steps to disclose as a company including setting up a CDP account, responding to the CDP questionnaire(s), and receiving a CDP score. 
+- A CDP score is a snapshot of a company’s environmental disclosure and performance. CDP's scoring methodology is fully aligned with regulatory boards and standards, and provides comparability in the market.

+### LEED
+LEED stands for Leadership in Energy and Environmental Design. It is the most widely used green building rating system in the world. LEED is an environmentally oriented building certification program run by the U.S. Green Building Council (USGBC). 
+LEED provides a framework for healthy, efficient, and cost-saving green buildings. It aims to improve building and construction project performance across seven areas of environmental and human health.
+![](https://www.sustain.ucla.edu/wp-content/uploads/2020/07/Capture-1.png)
+
+To achieve LEED certification, a project earns points by adhering to prerequisites and credits that address carbon, energy, water, waste, transportation, materials, health and indoor environmental quality. Projects go through a verification and review process by GBCI and are awarded points that correspond to a level of LEED certification: **Certified (40-49 points), Silver (50-59 points), Gold (60-79 points) and Platinum (80+ points)**.
