Project Details

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, within the confines of factors which are under our control, 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. This goal will be achieved through the development of an Integrated Action Plan (IAP), detailing strategies and potential interventions for mitigating air pollution in both the city, and surrounding region. The IAP will be based on development of a sound understanding of the current contributing factors to air pollution across the domestic, transport, industrial and agricultural sectors, for Delhi, as well as forecasting of how those sectors will change across the short, medium and long terms.

The plan can only be realised through the contributions of government agencies, local stakeholders and collaboration with population at large. The use of workshops, focus groups and extensive consultation will ensure that proposed strategies are realistic, clearly defined, well targeted and mindful of technological and social constraints. Above all strategies will be economically viable and environmentally sustainable. They will also be far-thinking and cross-cutting, embracing political, technological and behavioural change. The CADTIME project is envisaged to run over a 48-month period. Initial stages of the project will involve the development of modelling tools, such as collating emissions inventories and dispersion models, as well as the collection of information on current policies and best practice for mitigation within the city and region. The international nature of the consortium will allow a golden opportunity for academics and researchers from both nations to learn from each other.

Latter stages of the project will see collaboration with stakeholders coming to the fore, as the IAP takes definition and shape. Care will be taken to ensure that, wherever possible, the strategies defined for Delhi will also have relevance to other major urban areas in the sub-continent. In addition to Delhi, the CADTIME consortium includes the Indian Institutes of Technology of Madras and Bombay. Ultimately, the beneficiaries of the CADTIME project will be the Indian People and Government through a reduction in the burden of ill health that is inflicted upon them by air quality.

CADTIME consists of the following work packages:

  1. Baseline scenario development;
  2. Understanding current and proposed interventions and mitigation measures;
  3. Enhancement of modelling capability and emission projections for medium- and long-term horizons;
  4. Development of interventions and mitigation for current and future time horizons
  5. Evaluation of recommended interventions and mitigations;
  6. Coordination with other APHH Projects
