Port Houston’s initiatives to reduce emissions have shown some positive results, according to new data from the Port of Houston Authority.

Pulling from the Goods Movement Emissions Inventory (GMEI) report, which tracks port-related air emissions, Port Houston cited several improvements compared to the most recent report from 2019.

The port has seen total tonnage and container volumes increase by 16 percent and 28 percent, respectively, since 2019. However, greenhouse gas emissions have increased at a slower rate, growing only by 10 percent during the same time period, according to the data.

Additionally, emissions of nitrogen oxide fell by 7 percent, and emissions of particulate matter fell by 4 percent, despite adding 280 more pieces of cargo handling equipment.

“These results show that our emission-reduction efforts are working, and we are moving in the right direction,” Chairman Ric Campo said in a news release.

The Port Commission also recently approved items related to the $3 million U.S. Environmental Protection Agency Clean Ports Program (CPP) grant, which it received last year. The items will allow the port to work towards five new sustainability initiatives.

They include:

  1. An inventory of the port’s Scopes 1, 2, and 3 for greenhouse gas emissions
  2. A Port Area Climate Action Plan for the area and surrounding communities
  3. A CPP Truck Route Analysis
  4. Creation of the CPP Trucking Industry Collaborative
  5. Design of a customized website for Port of Houston Partners in Maritime Education, which is a non-profit leading maritime workforce development effort in local schools

A new partnership between The Hertz Corp. and the City of Houston will bring 2,100 rental electric vehicles to Houston, according to an announcement from the organizations earlier this week.

Dubbed Hertz Electrifies Houston, the program aims to boost Houston's EV rental fleet, as well add to the city's charging infrastructure and EV education and training opportunities.

The new vehicles will come from automakers Tesla, Polestar, and GM and can be rented to leisure and business customers, as well as rideshare drivers.

In partnership with bp pulse, Hertz Electrifies Houston will also bring a new EV fast-charging hub to Hobby Airport that's designed to serve ride-hail, taxi fleets and the general public.

"Our goal is to convert all non-emergency, light-duty municipal vehicles to electric by 2030," Mayor Sylvester Turner says in a statement. "This partnership with Hertz will provide an invaluable boost to achieve this goal and the goal of our Climate Action Plan for Houston to be a net-zero city by 2050."

In addition to the new fleet and charging hub, Hertz announced it will also donate an EV to Lone Star College-North Harris to help the college provide EV training to students in its auto servicing curriculum.

"Lone Star College-North Harris houses one of top automotive programs in Texas," Archie Blanson, president of Lone Star College-North Harris, says in the statement. "To make our students competitive and meet industry demand, we must ensure we are bringing the latest technologies, including a diversified fleet of EVs into the classroom.”

Earlier this month, Hertz also launched a Hertz Electrifies program in Denver. The initiative aims to bring 5,200 rental EVs to Denver. In 2022, the company first announced its plan to partner with bp pulse to install a national network of EV charging solutions for its customers.

Houston also has grown into a hub for EV and EV charging innovation recently. Houston-based Zeta Energy is leading efforts to develop efficient EV batteries, and received $4 million in funding from the U.S. Department of Energy's ARPA-E Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program earlier this year.

Houston's Revterra has also created a kinetic energy storage system that enables rapid EV charging. The company’s founder and CEO, Ben Jawdat, spoke about the energy transition on the Houston Innovators Podcast last month.

Cleantech incubator announces location in Houston, names newest partners

Greentown's moving in

After announcing its plans to expand to Houston in June, Boston-based Greentown Labs has selected its site for its cleantech startup and tech incubator.

Houston Mayor Sylvester Turner and the Greater Houston Partnership announced that Greentown Houston will be opening in the Innovation District, being developed by Rice Management Co. and home to The Ion. The site is located at 4200 San Jacinto St., which was Houston's last remaining Fiesta grocery story before it closed in July.

The facility is expected to open this coming spring and will feature 40,000 square feet of prototyping lab, office, and community space that can house about 50 startups, totaling 200 to 300 employees.

"We are thrilled to announce the selection of Greentown Labs' inaugural location in partnership with RMC, the City of Houston, the Partnership, and leading global energy and climate impact-focused companies," says Emily Reichert, CEO of Greentown Labs, in a press release. "In order to meet the urgent challenge of climate change, we must engage the talent and assets of major ecosystems around the country. We look forward to catalyzing the Houston ecosystem's support for climatetech startups as we work together toward a sustainable future for all."

Greentown Labs launched in 2011 as community of climatetech and cleantech innovators bringing together startups, corporates, investors, policymakers, and more to focus on scaling climate solutions. Greentown Labs' first location is 100,000 square feet and located just outside of Boston in Somerville, Massachusetts. Currently, it's home to more than 100 startups and has supported more than 280 startups since the incubator's founding. According to the release, these startups have created more than 6,500 jobs and raised over $850 million in funding

"We are so pleased that Greentown Houston will locate in the heart of the Innovation District, where they will seamlessly integrate into the region's robust energy innovation ecosystem of major corporate energy R&D centers, corporate venture arms, VC-backed energy startups, and other startup development organizations supporting energy technology," says Susan Davenport, chief economic development officer at the Greater Houston Partnership, in the release. "Houston truly is the hub of the global energy industry, and Greentown Houston will ensure we continue to attract the next generation of energy leaders who will create and scale innovations that will change the world."

Greentown Houston, which previously announced several founding partners in June, has just named new partners, including: RMC, Microsoft, Saint-Gobain, and Direct Energy. According to the release, Greentown Houston is also looking for Grand Opening Partners. Naturgy and and FCC Environmental Services (FCC) are the first to join on as a grand opening partners, and startups and prospective partners can reach out for more information via this form.

Reichert previously told InnovationMap that it was looking for an existing industrial-type building that could be retrofitted to meet the needs of industrial startups that need lab space. She also said that this approach is very similar to how they opened their first location.

The new location will be in the 16-acre Innovation District that's being developed by RMC, which will be anchored by The Ion, a 270,000-square-foot hub that is being renovated from the former Sears building.

"What we love about Greentown Labs as much as its commitment to helping Houston become a leader in energy transition and climate change action is its proven track record of job creation through the support of local visionaries and entrepreneurs," says Ryan LeVasseur, managing director of Direct Real Estate at RMC, in the release. "Greentown Houston, like The Ion, is a great catalyst for growing the Innovation District and expanding economic opportunities for all Houstonians. We're thrilled Greentown Labs selected Houston for its first expansion and are honored it will be such a big part of the Innovation District moving forward."

Acquiring the new Greentown location is a big win for the mayor, who released the city's Climate Action Plan earlier this year. The plan lays out a goal to make Houston carbon neutral by 2050.

"We are proud to welcome Greentown Labs to Houston, and we are excited about the new possibilities this expansion will bring to our City's growing innovation ecosystem," says Turner in the release. "Organizations and partners like Greentown Labs will play a vital role in helping our City meet the goals outlined in the Climate Action Plan and will put us on the right track for becoming a leader in the global energy transition. The City of Houston looks forward to witnessing the innovation, growth, and prosperity Greentown Labs will bring to the Energy Capital of the World."

Greentown Labs will host a celebratory networking event on September 24 at 4 p.m. Registration for the EnergyBar is open here.
