= The Climate CoLab seeks to harness collective intelligence through online contests. Anyone in the world can contribute their ideas to CoLab contests, but experts play an important role, too.
"Climate CoLab’s crowdsourcing project approaches its daunting challenge by first breaking the issue of climate change into dozens of smaller questions: How can we reduce greenhouse gas emissions from energy generation? How can we shift public attitudes toward climate change? How can we increase urban energy efficiency?
Each question forms the backbone of a contest in which experts, amateurs, and even artists are invited to propose potential solutions. Currently, 17 contests are active on the project’s website. Another seven are set to open soon.
All entries are posted to the site, where anyone can read them, leave comments, and ask questions.
“What’s nice about how the Climate CoLab is set up is it lets you gauge interest from other parties: What do they like? What message is getting across when you share this idea?” said Tim McGee, part of a team that proposed ways to alleviate the heat-island effect in Cambridge in a contest earlier this year. McGee’s team suggested addressing the problem — the tendency of cities to have higher temperatures — by using canopies draped between buildings and walls covered in plants to imitate the natural cooling cycles of a forest.
This year, the CoLab is adding a new layer of contests intended to generate more comprehensive plans for dealing with climate change. These competitions will ask entrants to combine existing ideas, from other contests or from outside sources, to create an integrated strategy for a geographical region.
For instance, a competitor in the India Plan contest might create a plan combining transportation, agriculture, and urban energy projects from other contests. “The idea is to get lots of people engaged in thinking about how can all the parts fit together,” Malone said.
Each contest produces a popular winner, chosen by online voting, and a judges’ winner, selected by a panel of experts. Judges also award a grand prize of $10,000 to one of the individual contest winners each year.
Once winners are chosen, the CoLab makes a point of helping participants connect not only with each other but with other people and organizations who can help bring proposals to fruition. At the end of each contest year, the CoLab hosts a conference at MIT to highlight the winning ideas and present new developments in the fight against climate change.
Last year’s big winner was Danielle Dahan, whose work as an energy efficiency engineer inspired a proposal to train maintenance workers to better use the sophisticated energy efficiency systems installed in most new buildings today.
Dahan plans to spend this summer figuring out how best to get her plan off the ground, before starting a master’s program in technology and policy at MIT in the fall.
“You don’t usually get to think big about energy and think outside the box you work in,” Dahan said. “Just the title ‘grand prize winner’ has been helpful to get attention from people and support.”
The first round of competition was held in 2009, but nearly two-thirds of the 1,000 proposals submitted came last year, Malone said. The number of people registered to view and vote on submissions has tripled over the past year to 34,000, including participants from almost every country in the world.
The obvious advantage of crowdsourcing is it creates a large pool of ideas. And more ideas mean more chances of finding a great proposal, said Karim Lahkani, principal investigator at the Crowd Innovation Lab at Harvard University. The approach can also encourage a greater diversity of ideas, he added, because anyone can participate; no managers pick the “best person” to work on a project.
One CoLab contest is focused on finding strategies to help Somerville reach its goal of becoming carbon-neutral by 2050. Reaching out to the crowd is a promising approach to such an ambitious goal, said Emily Reichert, one of the contest judges and chief executive of Greentown Labs, a clean tech incubator in Somerville.
“What the platform allows you to do,” she said, “is to access a community that is already engaged in addressing climate-related issues on a global scale, rather than going in a room and hiring a consultant and making it a closed-door process.” (http://www.bostonglobe.com/business/2015/05/10/address-climate-change-mit-lab-seeks-wisdom-crowds/uZUNE1MoIg22e995R5nyZI/story.html)
