IBM Call for Code Global Challenge

IBM: Using Open Source for the Greater Good


For the past four years, IBM has hosted its annual Call for Code Global Challenge — a worldwide, open-source competition that brings together start-ups, academic leaders, NGOs and enterprise developers to tackle the world’s most pressing societal issues. And as a global initiative, there was no greater challenge to address in 2021 than climate change.



The competition invited developers and innovators to address climate change with an emphasis on three sub-themes, all of which are key to combatting the global issue: clean water and sanitation, zero hunger and responsible production and green consumption.

Standing out in the media landscape on an issue that many find overwhelming presents a challenge all its own. Since 2018, we’ve partnered with IBM to ensure this initiative garnered attention and propelled people to action – even if they weren’t on the ground directly.


From the launch of the 2021 competition in March to the virtual ceremony in November, our team helped generate over 15.2K articles and social posts that highlighted the winning teams and over 15K solutions from the program since 2018. The Call for Code Global Challenge fostered the creation of practical, open source-powered applications – using technology to make an immediate and lasting humanitarian impact in communities around the world.
