There are two things that made this an exciting project for me. First, what started out as an idea in the mind of one Googler became a live feature in a product used by millions of people every day. And second, the launch of this feature in April 2010 marked the first time that individual investors could freely access this kind of information in conjunction with financial data.
Why would investors be interested in a company’s carbon disclosure rating? We thought it would be useful because a company’s emissions, as well as climate change more generally, can pose financial risks -- and investors generally like to understand such risks. These risks can take several forms: from regulatory risks (e.g. legislation placing costs on carbon-intensive activities) to physical risks (e.g. sea-level rise threatening a company’s facilities) to market risks (e.g. consumers switching to another company’s products because they believe that company to be a better environmental steward). All of these factors (and others) go into CDP’s calculation of a company’s carbon score, so it can be a useful metric for investors.
As I begin my sixth year at Google, I’m excited that we’re making environmental information more universally accessible and useful, and I’m looking forward to the projects and challenges ahead.
