The Clean Air for Delhi Through Interventions, Mitigations and Engagement (CADTIME) project aims to understand what is required to deliver significant reductions in levels of air pollution in the Indian capital, through affordable, effective interventions that consider and respond to future changes. CADTIME brings together a consortium of institutions and experts from across both India and the United Kingdom with the goal of addressing air quality issues that affect people's health in Delhi.

CADTIME itself is part of a larger consortium of five projects, running concurrently as part of the 'Atmospheric Pollution and Human Health in an Indian Megacity' (APHH India) programme. The APHH India programme is a four-year programme jointly funded by the Natural Environment Research Council (NERC), the Medical Research Council (MRC), the Newton–Bhabha Fund, and the Ministry of Earth Sciences (MoES) and Department of Biotechnology (DBT).
