The China Urban Transportation Emissions Calculator (CUTEC) private vehicles (PV) version 1.0 is the fruit of iCET's CTTP's year of project development together with E4Tech. The calculator is meant to support urban transport decision making through the comparison of various policy impacts on local air quality and carbon emissions, as well as other related effects such as congestion. CUTEC is designed to be an open-source: it is an Office spreadsheet tool that enables insights into the entire design and calculation processes, it is adjustable to local conditions and requirements, and it is free for use. The calculator was refined through the support of the Shenzhen Urban Transport Planning Center in providing Shenzhen's actual fleet data. Among reviewers and contributors to CUTEC are the Shenzhen Transport Development Research Institute (TDRI), Shenzhen Tsinghua Graduate School, Sun Yet Sen University, the World Resources Institute (WRI) and others. The CUTEC project was funded by the Rockefeller Brothers Fund, the UK Strategic Posterity Fund, and the Blue Moon Fund.
