We are at the forefront of sustainable construction in the 21st century.

Columbia collaborates with clients to achieve our common objective of environmental stewardship and social responsibility. We are eager to use business to protect nature and our relationship with it by building projects that contribute to cleaner air, water, and soil. 
As best practices in sustainability and renewable energy evolve, Columbia employees learn and grow their careers with training and continuing education support. We have successfully achieved certification for a variety of sustainability ratings, including LEED Platinum, Gold, and Silver Certifications, WELL Building Certification, Green Globes Certification, and Net Zero Energy Buildings.

In addition to our LEED services, Columbia's Energy Division specializes in providing building performance assessment services. Our team identifies available financial incentives and rebates and implements integrated energy conservation solutions and energy efficient and sustainable measures.

Columbia acknowledges responsibility for our Greenhouse Gas (GHG) emissions and supports a low-carbon economy transition. We are always working to make Columbia a better and more sustainable company. We do this through company-wide initiatives that promote positive changes that reduce carbon emissions and increase individual employee and overall environmental health. 

Some example initiatives include: 

• 35% of Columbia’s annual electrical energy use is cleanly generated by our 87 kW Rooftop Solar PV array  (designed and built by Columbia, of course!)
• Free Electric Vehicle charging for all employees and guests 
• Shared Electric Vehicle program to reduce emissions
• LED temp lighting required on all jobsites
• LEED compliant Indoor Air Quality management required on all jobsites (not just LEED projects!)
• HEPA filters for personal health in jobsite offices
• First Boston-area contractor to join Building Green’s Contractor’s Commitment to Sustainable Building Practices
• Public supporter of Massachusetts’ adoption of a Net Zero Stretch Code 
• Columbia is actively engaged in improving construction recycling across the industry
