The next big wave in software products seem to be in developing carbon management software. With the increase in energy costs, environmental regulations and green branding the business is forced to track energy consumption to the last light bulb. This requires a huge amount of effort to collect, audit and analyze data on energy consumption. More than 150 software products are already in the market with most following a SaaS model. Some of them are going a step further and offer high end analytics to reduce carbon intensity.
