Clean Technology Meets Data Science: News and Articles

Anyone who’s ever visited an Indian city in the heat of summer will remember the feeling that the city itself is baking – heat radiates from the pavements, the buildings and there are fewer green areas to mitigate these effects. This is the urban heat island effect – when the city is much hotter than the surrounding areas. Urban heat islands are a common problem and are only going to get worse as the climate warms. This is especially true in countries closer to the equator – summer is hot but is now promising to get even hotter. One of the solutions that people have been looking at is “greening building facades” or more simply – growing plants along the walls of buildings – vertical greening. The advantages of “green building facades” are that the plants help reduce building temperatures through shading by the leaves, reducing the impact of wind and through evapotranspiration. Now, like any other natural system – growing plants vertically means that there are a number of parameters tha

  Let’s take a look at one of the traditional clean tech sectors –   sustainability accounting . Now, this is a term that’s used in many different contexts, but traditionally, it refers to the use and flow of materials and energy. This could be locally, within a company, regionally for a specific sector across countries or monitoring a specific material over the globe. Most large companies these days track their   metrics on sustainability   –   carbon footprint, water usage, waste, conflict minerals   and so on… These metrics and the associated analyses are typically presented in reports that are one-time downloads or available in obscure places on the web. So anyone who’s interested in tracking changes over space and time for a single company or a group of companies – congratulations! You just agreed to spend a huge amount of time trying to get the data before doing anything with it. Enter the company   ESG Trends . This company was started a few years ago and has made it easier to f

Fact – fifteen of the hottest years have come in the last sixteen years. If you are one of the people who is living through the heat waves and wondering if your asthma is really getting worse or if it’s just your imagination – well congratulations! You’re not alone and you are not imagining things. Scientists at the   University of California, Irvine    wanted to understand what happens to the air pollutants that trigger human health problems like asthma when heat waves occur simultaneously. In other words, if there is already air pollution does having a heat wave at the same time make the pollution worse? And if it does get worse, how badly does it affect people’s health?   In order to answer these questions, they overlaid detailed air pollution maps of the United States and Canada with meterological models and data about heat waves over a 15 year time period. The data was on a very fine 1 degree grid. What they found was that having both a heat wave and existing pollution resulted in
