The Code4Green sustainable hackathon goes into its second round – and it needs your ideas!

Factsheet Code4Green Hackathon


The German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) invites students, innovators, scientists, designers and entrepreneurs from all over Europe to take part in the second edition of the Code4Green hack. Teams of 5-7 are invited to code and present a prototype of how to use European environmental data for sustainable digital solutions.


As we recover from the pandemic, Europe will be facing far-reaching decisions: How do we work towards a green recovery that is resilient, inclusive, and sustainable? We are currently undergoing both an ecological and a digital transformation. Digitalisation without regard for the environment and climate impact can exacerbate existing problems. At the same time, we cannot solve our environmental problems without digital tools and data. Code4Green 2.0 aims to unite Europe’s brightest minds to find innovative and data-based solutions to ecological challenges. We believe that a better and more sustainable future for Europe is possible by reaching out, thinking creatively, and working together.


10 to 12 July 2020

Teams will be made up of 5 to 7 people.

Applications are currently open:

Topics and Challenges

Climate Change

Climate Change is a central challenge for our societies in the coming decades. By switching to renewable energy, we can greatly reduce carbon emissions. Innovative and new solutions are needed for a transition to renewable energy, as well as to improve the quality of life for current and future generations.


How can we use environmental data to better and more sustainably produce and store renewable energy in communities all over Europe?

How can we use environmental data and digital tools to mitigate and adapt to climate change at the same time?



The unsustainable way in which we are currently using land is contributing to the loss of biodiversity. We need to reconcile the economic well-being of people and ensure the survival or diverse flora and fauna for the survival of our planet.


How can we use environmental data to make agriculture and land use more sustainable?

How can we use digital tools to support biodiversity?

How can digital technologies help to modernise biodiversity protection measures?


Circular Economy

Producing goods depends on scarce natural resources that are often imported. At the same time, discarded products cause huge amounts of waste. We need to understand the ecological footprint of products better, use them longer and re-use resources at the end of their lifecycle. Reducing our consumption and waste footprint, designing durable and easy to repair products and providing visibility to supply chains are all key building blocks of a European Circular Economy.


How can we use environmental data to create solutions for a more sustainable production cycle?

How can we reduce waste, extend product lifetimes, and recycle sustainably?



A total of €10,000 will be awarded to the three winning teams of the Code4Green Sustainable Hack. In addition, teams will receive three months of tailored mentoring and coaching to take their prototype to the next level. They are invited to pitch their solutions to the European environmental ministers in Berlin at the beginning of October 2020.
