This is a sample project description: elect 50-100 stocks from the Russell 3000 index ensuring all sectors are represented. 2. Present past 24-60 monthly return descriptive statistics for your market cap-based portfolio including mean, standard deviation, min, max, and percentiles. 3. Set up and solve the optimisation problem that finds a mean-variance efficiency frontier with standard objective and constraints. Discuss the properties of mean variance frontier you obtained. 4. Redo the exercise in in Point 3 above with additional greenhouse gas emissions (sum of latest Scope 1 and Scope 2 emissions) constraint in following different forms: Raw emissions Emissions scaled by revenues Industry level standardised emissions scaled by revenues For each above greenhouse gas emissions measure, the constraint is your portfolio emissions should be less than equal to median raw emissions of all the stock in sample. Which of these three forms of greenhouse gas emissions constraint you would prefer? 5. Compare mean variance frontier you obtained in Point 3 and Point 4 above. My question: In the context of this project, please explain to me what do you mean by 'Industry level standardised emissions scaled by revenues'
