Sustainability Services
Let us make the business case for your projects, so you can focus on the impact

Financial Modeling
We provide financial analysis for your sustainability projects. We model the return on investment and net present value for your renewable energy, climate change mitigation, energy efficiency, and/or water projects. We work with you to understand which financial metrics matter to your organization, and deliver a tool that is specifically designed to your needs. Our financial tools include user friendly functionalities such as buttons and drop down menus, so that even the novice Excel user can use them. We go beyond delivering an Excel file and make sure that you understand the numbers and help you make the business case for your projects.

Environmental Impact Modeling
We know that our clients care about environmental impact. In order to reach your sustainability goals, you have to measure them. We estimate the environmental impact of your projects, both the amount of greenhouse gases mitigated as a result of your project and the amount of water saved. This information is useful for end of the year reporting and to understand which sustainability projects should take precedence. We deliver our analysis in an easy-to-understand Excel tool.

Economic Analysis
If you want to monetize the impact your policy or project has on society at-large, this service is for you. The economic value of a project includes the societal and environmental costs and benefits. We use metrics such as an increase in Gross Domestic Product (GDP) or the social cost of carbon to monetize impact. For example, when a clean energy project provides jobs, this is a social benefit, or when it improves air quality, this is an environmental and health benefit. We deliver a user-friendly Excel tool with clear and stated assumptions about the economic inputs.

Environmental Disclosures Strategy
A growing number of investment decisions are made with Environmental, Social, and Governance (ESG) indicators. What you disclose publicly on sustainability reports impacts how investors evaluate your company. Lange Group Consulting develops a clear and integrated strategy for sustainability reporting. This includes a review of your public disclosures and actionable recommendations to improve your ratings. We work with investor relations and sustainability teams to ensure consistent messaging and to identify areas to streamline the sustainability reporting process across teams.
