2015 Environmental Sustainability Report
Shaping a Renewable Future

CFO’s Message

Mike Castro, Chief Financial Officer

The past several years, we have been making efforts to “green up” our business, working with a sustainability partner to take a hard look at our operations and help us take steps to reduce our carbon footprint. In addition to developing a number of waste reduction programs, including recycling and composting, we continue to reduce our overall spend on resources and increase our green purchasing. We are using less paper — which means we are printing less — and we’re appealing to our providers, enrollees and employees to join us increasing the sustainability of how we do business. This includes the promotion and adoption of paperless benefit statements.

I invite you to take a look at our Environmental Sustainability Report and see the progress we’ve made over the past few years. And of course, comments and suggestions are welcome — please send them to GoingGreen@delta.org. Thank you for helping our efforts to be leaner and greener!

Waste Diverted from Landfills

We committed to reducing the amount of trash sent to landfills and implemented better tracking to measure our progress. We continue to redirect more than 50% of our waste into reuse or recycling program.

Paperless Adoption

Adult enrollees are transitioning to online-only account management. This is a large opportunity for us to pioneer this effort in a historically paper-heavy industry. We need your help! Sign up to go paperless.

Innovative recycling programs allow us to keep more than half of our waste out of landfills. An employee-led polystyrene/foam initiative, a regional biodiesel program, an electronics-specific recycling bin and in-office composting are reasons for our success. We are proud to partner with local experts who are taking bold steps to reduce landfill volume.


2015 Purchasing Overview

Over the last five years, we have made a concerted effort toward reducing our overall consumption of supplies while simultaneously working to increase the proportion of green products we use in all of our facilities.
