Road to Net Zero

There is no escaping the fact that we need to change - and soon. To reach the goal of Net Zero by 2050, we need to reduce our reliance on carbon-intensive materials and processes. We evaluated the advantages of taking your confidential document delivery digital in research conducted with Project Rome's Simon Pringle, Associate Fellow Of Chatham House & Professor at Edinburgh University.

Lower costs

Through our consultancy process, we found that for businesses with high outputs, secure email generates 95% savings on print, pack, and post.


Carbon savings

Taking into account the full lifecycle of paper production and delivery, secure email helps businesses to reduce their carbon impact by over 80%.

What could you save?

Take our 2-minute online assessment to see how much carbon you could save by switching from post to secure email.

Time to change?

Switching a portion of your sensitive document output to secure email is an immediate step towards carbon output reduction, but it's not just the carbon cost that makes tracked post unsuited to sensitive information exchanges. Security, compliance, and efficiency are among the benefits of digital alternatives.
