Climate action for URBan sustainability (CURB) scenario planning tool

Climate action for URBan sustainability (CURB) is an interactive scenario planning tool designed specifically to help cities take action on climate change. The user-friendly tool allows cities to:

  • Identify and prioritize low-carbon infrastructure and other greenhouse gas reduction actions;
  • Quickly understand the impact on emissions and financial performance of potential actions;
  • Develop, compare and explore multiple scenarios;
  • Draw on extensive built-in city, national and region-specific data to refine this with city specific data where available.

CURB is being used by cities to explore potential emission reduction targets, support development of city climate action plans, and prioritize investments.

How does CURB work?

Emissions forecasts: Users input GPC inventory data. CURB then generates activity and emission forecasts using default or custom growth rates.

Emission target setting: CURB allows users to select emission or energy targets for three horizon years. User can select different types of target: absolute, intensity or scenario based targets.

Reduction actions in 6 sectors: CURB contains over 50 city greenhouse gas emission actions in six sectors: private sector buildings, municipal buildings and public lighting, electricity generation, solid waste, transportation; and water and wastewater.

Financial analysis: CURB provides details of implementation cost, cash flow, payback and return on investment. Users can change discount rate and cost assumptions to evaluate the impact of alternative financing conditions.

City co-benefits: CURB provides information on the other non-emission related benefits that actions could provide to the city.

Comparisons of multiple scenarios: CURB allows comparison of four alternative scenarios. Scenarios can be varied using different packages of actions, implementation assumptions, or financing assumptions.
