‘Let’s Go to Hack4Climate’: Leveraging Blockchain to Fight Climate Change

22 Sept 2017, Impact Hub Singapore

How can we use blockchain for carbon pricing, energy distribution, and other climate challenges? This question brought twenty-odd individuals together at ‘Let's go to Hack4Climate’, a pre-workshop event organised by Impact Hub Singapore in the run-up to the hackathon in Germany later this year. Pizza, beer, and cutting-edge environmental technology solutions on a Friday evening, what more could one ask for?

'Let’s Go to Hack4Climate’ drew twenty-odd participants with diverse interests and expertise.

Willie and Ying Tong from the SSN team joined in this night of ideation and discussion. As members of the environmental community and sometimes-event organisers, here’s what we took away from the evening:

  1. Environmental efforts must engage the tech community. Over the course of a few hours, we met an AI researcher, an energy plant technician, a patent attorney, a global development strategy consultant… we could go on! While we'll definitely be keeping in touch with our new friends, we unfortunately did not meet any blockchain experts. Perhaps this raises a bigger issue: how can the environmental and technological communities further engage each other? It often seems like one side has all the problems, and the other side the solutions: and events like Hack4Climate are a first step in bringing them together. We hope to see more of such envirotech collaborations in future events.

  2. Good ideas come from balanced discussion formats. We found the format of this event very effective for ideation, in two ways:

    1. Transition from guided to organic discussions. Information sessions and guided frameworks helped to focus the discussion at the start. In the rapid Round One of ideation, we were told to follow the format: “We solve [problem] with [technology] by [outcome].” After the initial ideas took shape, we then transitioned to more organic and longer discussions.

    2. Mix of breakout and whole-group activities. A mix of big-picture whole-group discussions and in-depth breakout group sessions provided both breadth and depth to the ideas generated.

Teams share their solutions on one of five climate issues: emissions tracking; carbon pricing; distributed energy; sustainable land use; or sustainable transport.

Some exciting climate solutions that came of the evening were: uploading emissions and tracking data to the blockchain for transparency; smart contracts that penalise energy-inefficient mobility; and using machine learning to identify indicators of carbon-intensive activities. A few teams are seriously considering applying to the Hack4Climate challenge with these ideas. The hackathon will be held in conjunction with COP23 in Bonn this November.

Overall, our greatest takeaway is the need for the environmental community to increase engagement with the tech community. ‘Let’s Go to Hack4Climate’ was an effective example of this initiative.

Some questions to consider:

  • What are some other effective formats to encourage ideation and problem-solving?
  • How else can environmentalists and technologists collaborate in Singapore?
