If you want to be a member at either Boston-area or Houston location of Greentown Labs, you better have a small carbon footprint.

Leading global venture capital firm Clean Energy Ventures, which funds early-stage climate tech innovations, announced a partnership to offer access to the firm’s Simple Emissions Reduction Calculator (SERC) to Greentown Labs, the largest climate tech incubator in North America that is dually located in Houston and Sommerville, Massachusetts. New members will be required to report their CO2e emissions reduction potential as part of the incubator’s climate impact assessment as part of the Greentown Labs’ application process.

Greentown Labs has nurtured more than 525 companies across its two locations with a 94 percent success rate for startups. Greentown Labs supports and fosters collaboration with corporates, early-stage entrepreneurs, investors, government and other players while providing members access to labs and resources.

“As we continue our work to support the most innovative climate tech startups, we’re doubling down on how we quantify impact — both the impact Greentown Labs is having on the entrepreneurs we’re privileged to support, and the impact the startups themselves are having by reducing greenhouse gas emissions,” Kevin Knobloch, CEO and president of Greentown Labs, says in a news release. “Having access to this timely tool that Clean Energy Ventures has created is elevating our recruitment efforts and helping us standardize how we quantify the projected impact of our member community.”

CEV developed SERC in 2021 to assist startups with tools and algorithms to estimate their technology or business model’s emissions reduction potential. SERC is now used as an essential screening tool in over 1,000 companies asn a climate tech accelerators, incubators and investors across the globe, and was awarded an honorable mention by Fast Company World Changing Ideas in 2022.

“As climate tech investors, we are always eager to support the growth of an ecosystem of innovation and impact,” CEV Managing Partner David Miller in says in the release. “With the number of climate tech companies seeking investments today, startups that are able to estimate their innovation’s capacity to mitigate CO2e emissions truly stand out from the crowd and are more likely to secure investment. Through SERC, investors are able to gain critical insight to back the most impactful technologies with the potential to address climate change as quickly as possible over the next two decades.”

Rice University chemistry professor László Kürti was named as a recipient of the 2025 Ross M. Brown Investigator Award from the California Institute of Technology’s Brown Institute for Basic Sciences.

Kürti is one of eight mid-career faculty members to receive up to $2 million over five years for their research in the physical sciences.

“I’m greatly honored,” Kürti said in a news release. “We will learn a tremendous amount in the next five years and gain a much clearer understanding of the challenges ahead.”

Kürti was selected for the research he’s been developing for six years on a molecule called tetrahedral N4, which studies show can release large amounts of energy on demand. The molecule can also decompose directly into nitrogen gas without producing carbon dioxide or water vapor. Kürti believes N4 can be used as a "new type of fuel for vehicles."

“Eventually, N4 and other stable, neutral polynitrogen cages could be used to power rockets, helping us reach the moon or Mars faster and with heavier payloads,” he added in this release.

The Brown Investigator Awards were founded by entrepreneur and Caltech alumnus Ross M. Brown and established by the Brown Science Foundation in 2020. The organization has recognized 21 scientists over the last five years.

“Midcareer faculty are at a time in their careers when they are poised and prepared to make profound contributions to their fields,” Brown said in the news release. “My continuing hope is that the resources provided by the Brown Investigator Awards will allow them to pursue riskier innovative ideas that extend beyond their existing research efforts and align with new or developing passions, especially during this time of funding uncertainty.”
