SYDNEY, Oct. 5. 2012 /PRNewswire/ -- CarbonSystems has been named a top-five global leader in the enterprise carbon accounting (ECA) and sustainability software market in a new report analysing the performance of 75 software vendors. The analysis released today by Groom Energy confirms the increasing adoption of ECA and sustainability software by large corporations seeking to track and report their sustainability performance in areas such as carbon emissions, energy, water, supply chain and waste. In the last 24 months more than 600 large corporations including American Airlines, Adidas, Microsoft and Volkswagen Group have adopted ECA and sustainability software. The new report is intended as a buyers' guide for organisations seeking independent advice about software vendors that can best meet their needs. Its intended audience includes CIOs, CFOs, Directors of Sustainability/Energy/Facilities, and sustainability and environmental consultants. The analysis reveals three leading drivers to adopt enterprise carbon accounting and sustainability software: requests from top customers for annual environmental data; a desire to enhance company image and increase brand loyalty; and, cost savings from improved energy management. The report ranks software vendors on five weighted criteria - number of customer deployments, technology features, sales momentum, market vision and financial stability. Inputs for each weighting were based on software demonstrations, vendor interviews, customer discussions and case studies. "This new analysis confirms the maturation and consolidation of the carbon and sustainability software market with a trend for a handful of top vendors to win increasing market share," says CarbonSystems CEO, David Solsky. "Buyers of carbon accounting and sustainability software want solutions that offer fast deployment and broad functionality that can be easily tailored to their assets and facilities. "The report confirms our view that corporations want software that lowers the cost and complexity of capturing, managing and analysing their sustainability data so they can improve their operational and financial performance. It also reveals that pressures such as carbon emissions regulation, rising energy costs and investor expectations are driving more large corporations to be more accountable for their sustainability performance."
