Denver Public Schools and The Greenway Foundation collaboration launched

April 2024

We passed out 4000 hot sleeves to 18+ schools across Denver K-12 and asked students to draw any Earth Month related image – the results were fantastic, inspiring, hilarious, and outrageous. We loved it! See one of our favorite examples to the left.

Annual waste audit

April 2024

We've completed at least two waste audits beofre all three reports that have been published. Audits are the only way to know how customers are deciding what to recycle vs throw away. How do we complete one, you ask? We dump out your trash/recycling and count everything inside!

Heat pump installed at Blake Street

March 2024

With help from the City of Denver’s Electrification Feasibility Report Pilot Program, we replaced our outdated, over worked, unreliable heating and cooling unit with a new, efficient, electric, heat pump.

March 2024

We waited a long time for this one. Now, $0.50 from every bag of Blue Sparrow Coffee we sell will be donated to Zero Foodprint to help fund regenerative agriculture across the US.

December 2023

*MAINSPRING is our parent company, meaning we aren't a Certified B Corp but our work played a role in them becoming one!

Changed "Sustainability" Fund to subsidize alt-milks

We decided to subsidize the cost of alternative milks to keep prices low on lower impact options within our store. 100% of our single-use charge now goes to keeping alternative milks cheaper, in the name of "sustainability".

Replaced sugar packets w/ refillable syrups

Tracked our "recyclables" to see where they were really going

August 2022

Remember this? We decided to replicate the experiment by placing GPS devices in to-go cups and sending them off to be recycled (fingers crossed). One was quickly lost, the other ended up in the dump, and the last one standing made it allll the way to a landfill outside of Boulder, CO.

First barista training

July 2022

Baristas are the voice of our “sustainability” work, we implemented quarterly trainings in year one to ensure they are up to speed on the initiatives we are launching, our reports, and the environmental science behind our work. Oh yes, and they’re paid to learn all of this. Click here to see the first training!

Changed our customer facing napkins

June 2022

We removed the "100% recycled content" branding on our napkins to reduce the chances of them contaminating our recycling bin. Our first waste audit made it clear that they were a top contaminate. Anecdotally, it totally worked!

Compost added at Platte Street

June 2022

Compost added at Blake Street

May 2022

Adding compost allowed us to ensure 100% of all coffee grounds were being diverted from the trash.

Added MS Marketplace to slack

May 2022

We created our own version of a used goods marketplace for staff 35+ staff members to share items they no longer want and keep their closet clean outs circular!

Daily trash sorting for BSC X Alejandro Gaeta Earth Day collaboration dress

March 2022

Our 2023 Blue Sparrow Coffee x Alejandro Gaeta collaboration was made of 100+ used to-go cups, so we stopped by the store at the end of every day to gather them for our designer!

Tried to donate our leftover pastries

March 2022

Turns out we don't have many! We loved the idea of partnering with local non-profit We Don’t Waste, but we rarely had leftovers to share. Currently, any leftovers get taken home, handed out, or composted.

First water meter reading at Platte Street

March 2022

In response to our year two water data (which was x2, x3, x5, even x10 times higher than the year before) we started reading the meter ourselves. We continue to do this twice a month and won't stop until we understand our water usage.

Put our lighting on a tight schedule to reduce energy use in stores

March 2022

Single-Use Initiative launched

January 2022

We started charging $0.10 per single-use cup going out our doors, knowing that customers are more likely to change behavior when they're fined than when they’re rewarded. All single-use fees go back into our “Sustainability” work at Blue Sparrow Coffee. Read more, here.
