Energy company Dalkia adds 'delete by' dates to social media posts

Dalkia isn't foisting the responsibility for carbon-conscious behavior on consumers. In addition to tagging its own posts with #dld, the company redesigned its website for lower energy consumption. From reducing the number and size of images and videos on each page to switching from seven to two servers (and shutting down one of the two every evening and weekend), the new site uses 64% less energy than its precursor.

As Dalkia's CEO, Sylvie Jéhanno, explains: "When we use the internet, we are not really aware of the energy consumed by what we read, watch or listen to — despite the fact that the digital world accounts for 4% of global greenhouse gases—more than air travel! We decided to design our site sustainably, in line with Dalkia's business lines, to take collective action and perhaps inspire others to do the same."

(And yes, we at TrendWatching are acutely aware that we need to lower our own carbon footprint, too...)
