Why are Life Cycle Assessments becoming an increasingly important means of evaluating cleantech performance and economics? First, consumers, businesses, insurers and regulators are increasingly denouncing greenwashing, and demanding more fact- and science-based environmental impact analyses. Second, these assessments include verifiable Environmental Key Performance Indicators (EKPIs), which enable cleantech developers and investors to make informed decisions about which technologies to invest in, and how best to evolve their operations. Finally, LCAs also help investment managers ensure that they and their customers have full insight into the risks and opportunities in portfolio companies. The assessments examine sourcing and type of materials used, greenhouse gas emissions, energy efficiency and resiliency.
