  • Health impact of tyre particles causing “increasing concern”, say scientists

    Health impact of tyre particles causing “increasing concern”, say scientists

    Scientists at Imperial College London say particles from car tyres are particularly harmful because of the toxic chemicals they are made of. 

    The report, based on data from the UK government, shows a significant increase in fine particulate pollution.  According to the research, tyre and brake wear will account for 52% of all fine particulate pollution from road transport in 2021, while wear on roads and their paint markings will contribute a further 24%. Only 15% of the pollution came from car exhausts, with a further 10% coming from vans and lorries. In addition, emissions from UK vehicles have fallen by 90% since 1996. The UK government’s environmental data has given the researcher a good insight into the main causes of transport pollution.  Ongoing measurement, monitoring and analysis helps researchers identify the problem and begin planning the solution.

  • How a cost-benefit analysis can help reduce emissions in the transport sector!

    How a cost-benefit analysis can help reduce emissions in the transport sector!

    We live in the era of Big Data. One of the challenges we face in reducing emissions is converting technical information (big data) into actionable materials that help people or organizations shape strategies.

    Cost-benefit analysis serves two purposes: to verify that the benefits of an investment (or project) outweigh the costs, and to compare different costs. 

    The Climate and Clean Air in Latin American Cities (CALAC+) project has developed three tools to help evaluate emission reduction strategies and plans using the cost-benefit method.

    1. The benefits of better air for people and the environment

    Sparrow is a unique turnkey solution that measures more than 15 different parameters without investing in new infrastructure, at street level, 24/7 and creates Big Data as a result. Once Big Data is collected, we incorporate it into an urban development strategy for a cleaner and more sustainable future.
