The focus areas

Responsible production and green consumption

Worldwide consumption and production drives the global economy yet is inextricably linked to the environment. For example, the number of air conditioning units worldwide is expected to almost triple to 5 billion by 2050, which will drive sharp growth in electricity consumption. Technology can help in many ways, from recommendations on energy efficiency to highlighting the carbon footprint of online purchases.

Clean water and sanitation

Water is the natural resource that is most threatened by climate change and is a prerequisite for life on earth. From intelligent solutions for small farmers to recycling showers, technology can make a significant impact on the availability of water and its consumption.

Zero hunger

135 million people suffer from acute hunger, with climate change a major contributing factor. Technology can help farmers grow more crops in areas on the edge of drought or communities to quickly distribute perishables from small stores to local homeless shelters.

About the conference

The best way to get started on your Call for Code Global Challenge submission—starter kits from the experts.
