Boston's BERDO Regulations: What to Know for Compliance

Mon 06/15/2026 - 11:41

Understanding Boston BERDO compliance is essential for large commercial and multifamily building owners, as covered buildings must meet annual emissions standards starting in 2025 or 2030. Navigate compliance and avoid fines with guidance from SOCOTEC.

Boston’s BERDO (Building Emissions Reduction and Disclosure Ordinance) is one of the most ambitious municipal climate regulations in the United States. For building owners and property managers across Boston, failure to comply with BERDO can result in fines. As the City of Boston accelerates its decarbonization goals, large commercial and multifamily buildings are at the center of this regulatory shift.

With buildings accounting for nearly 70% of Boston’s greenhouse gas emissions, BERDO 2.0 introduces progressively stricter emissions standards that will reshape how buildings are designed, operated, and valued.

Evolution & Goals

What Is Boston's BERDO Regulation?

Introduced in 2013 and updated in BERDO 2.0, the Boston BERDO ordinance is a comprehensive climate policy requiring large buildings to track, report, and ultimately reduce their greenhouse gas emissions. Originally enacted as a disclosure-focused regulation, BERDO evolved significantly with amendments that transformed it into an emissions reduction mandate.

BERDO's Evolution

The City of Boston's BERDO initially focused on transparency, requiring building owners to annually report energy and water consumption data. This foundational phase established baseline emissions profiles across Boston's building stock.

BERDO 2.0, adopted in 2021, fundamentally changed the regulation's scope. The updated ordinance introduced:

  • Mandatory emissions reduction targets aligned with Boston's 2050 carbon neutrality goal
  • Five-year compliance periods with progressively stricter performance standards
  • Independent third-party verification requirements for energy reports
  • Financial penalties for non-compliance
  • Public disclosure of building emissions performance data

The regulation targets building emissions reduction through a performance-based framework, allowing owners flexibility in choosing their decarbonization pathway while maintaining accountability for results.

The regulation targets building emissions reduction through a performance-based framework, allowing owners flexibility in choosing their decarbonization pathway while maintaining accountability for results.

BERDO's Goals

Boston BERDO aims to achieve net-zero emissions in the building sector by 2050 through interim targets specific to each building use. In general:

  • 2025-2029: First compliance period with baseline emissions standards
  • 2030-2034: Emissions limits reduce by approximately 20%
  • 2035-2039: Further reductions toward mid-century targets
  • 2040-2044: Aggressive reductions approaching net-zero
  • 2050: Full carbon neutrality achieved

These phased requirements provide building owners time to plan capital improvements while ensuring steady progress toward climate goals.

Owners who plan early can move beyond compliance and use BERDO as a framework to improve efficiency, manage risk, and protect long-term asset value.

Which Buildings Are Subject to BERDO?

Boston BERDO requirements apply to large buildings based on size thresholds:

Buildings and properties meeting these criteria must comply:

  • Large commercial buildings that are 20,000 sq. ft. and above
  • Multifamily buildings with 15 or more units
  • Parcels containing multiple buildings that sum up at least 20,000 square feet or 15 residential units

  • Boston BERDO: Large buildings in Boston, Massachusetts.
  • Newton BERDO and Cambridge BEUDO: While primarily focused on Boston, similar requirements extend to neighboring municipalities such as Newton and Cambridge, Massachusetts.
  • Other Massachusetts communities are considering comparable ordinances.

Note that timelines and coverage may vary in other regions. Contact a BERDO specialist at SOCOTEC to learn more.

Building owners, not tenants, bear primary compliance responsibility, though tenant cooperation is often essential for achieving emissions reductions. This creates complex situations in multi-tenant properties where operational control is distributed.

BERDO Emissions Reporting & Performance Requirements

Compliance with Boston BERDO reporting involves multiple interconnected obligations that extend beyond simple data submission. SOCOTEC is an energy consultant that helps translate BERDO requirements into actionable compliance plans, including energy audits, building envelope analysis, decarbonization strategies, and third-party verification.

Annual Reporting to the City of Boston

Starting with BERDO 2022 reporting cycles, building owners must:

  1. Track monthly energy consumption across all fuel sources, including energy usage not reported by utilities (electricity, natural gas, fuel oil, propane, etc.)
  2. Monitor water consumption annually
  3. Request tenant data if energy is purchased directly by a tenant
  4. Submit reports through the city's online portal by May 15th annually
  5. Obtain third-party verification from credentialed professionals (PE, CEM, or equivalent), required for the first reporting year, first emissions compliance year, and every five years thereafter.

Performance Standards

BERDO compliance requires buildings to meet emissions intensity targets measured in kilograms of CO₂ equivalent per square foot. These targets:

  • Vary by building type (office, retail, multifamily, etc.)
  • Decrease every five years
  • Apply penalties when actual emissions exceed allowed thresholds

Verification Requirements

Independent verification ensures data accuracy and credibility. Verifiers must:

  • Review utility bills and consumption records
  • Confirm building characteristics and square footage
  • Confirm all energy usage is accurately reported, including use of backup generation and EV charging station usage to be exempt from emissions standards
  • Confirm eligibility of any renewable energy credits (RECs) and power purchase agreements (PPAs)
  • Certify report accuracy through professional seal

This third-party oversight increases reporting rigor and establishes reliable baseline data for Boston's climate tracking.

Emissions Calculation Tools

Many building owners are undertaking decarbonization projects to meet BERDO compliance. SOCOTEC can assist with decarbonization studies to help your buildings comply. In addition, the BERDO Emissions Calculator and Emissions Compliance Projection templates are tools that building owners can use for future emissions planning, helping building owners understand current emissions and how emissions may change over time under future projects.

  • Electricity emissions decrease over time due to Massachusetts’ policy for a cleaner, more renewable grid
  • Fossil fuel emissions apply standard combustion factors, reducing only through efficiency, electrification or fuel switching

Fine & Payment

What is the fine for BERDO in Boston?

Fines and penalties for BERDO non-compliance can be considerable for building owners:

  • Reporting and verification violations: From $150 to $300 per day, depending on the property size
  • Emissions standard violations: From $300 to $1000 per day, depending on the property size
  • Inaccurate reporting: From $1,000 to $5,000 fine per discrepancy

Alternative Compliance Payments (ACP)

Rather than paying daily fines for exceeding emissions limits, building owners may choose to make an Alternative Compliance Payment (ACP) to the City of Boston, currently set at $234 per metric ton of CO2 above the allowed standard. Depending on the level of excess emissions, this option can be more cost-effective than ongoing penalties.

Owners facing technical or financial constraints may also request flexibility through individual compliance schedules or hardship plans reviewed by the BERDO Review Board.

      Frequently Asked Questions About BERDO

      BERDO stands for the Building Emissions Reduction and Disclosure Ordinance, the City of Boston regulation that requires certain buildings to measure, report, and reduce their carbon emissions.

      BERDO 2.0 Boston introduced mandatory emissions reduction targets, third-party verification requirements, and substantial penalties for non-compliance. Unlike the original disclosure-focused ordinance, BERDO 2.0 requires actual emissions reductions with enforceable standards.

      Yes, new building construction must comply with BERDO immediately upon completion. Designing new buildings to exceed minimum standards provides cushion as requirements tighten.

      Yes, existing buildings must comply with BERDO. Decarbonization planning helps older buildings achieve BERDO compliance.

      Buildings that cannot meet BERDO standards may be subject to fines that vary based on building size, the type of violation, and the duration of non-compliance. As an alternative, owners may opt to make an Alternative Compliance Payment (ACP), calculated per metric ton of emissions exceeding the allowed limit.

      They are numerical values provided by the City of Boston that refer to the regulated amount of emissions a BERDO building is allowed to produce during a year, converting energy usage (electricity, natural gas, heating oil, etc.) into carbon emissions (CO₂e). Emissions standards vary by building use type.

      Covered buildings must report annually, with submissions typically due by May 15 each year. Reporting is completed using the Boston BERDO calculator and requires accurate energy, fuel, and water consumption data from the previous calendar year.

      A qualified BERDO or decarbonization consultant can support building owners with emissions reporting, performance analysis, compliance strategy, and long-term planning to meet BERDO 2.0 Boston requirements. SOCOTEC combines deep technical knowledge with hands-on experience in state and local energy regulations, helping clients navigate complex compliance pathways while optimizing building performance and sustainability outcomes.

      Verification must be performed by independent, credentialed professionals including Professional Engineers (PE), Registered Architects (RAs), Certified Energy Managers (CEM), or equivalent qualified parties not employed by your organization. At SOCOTEC, we can provide comprehensive verification services to ensure your emissions data is accurate, compliant, and ready for submission.

      Yes, renewable energy certificates (RECs) and power purchase agreements (PPAs) receive appropriate credit in emissions calculations, though specific rules govern their application and documentation requirements.

      BERDO operates alongside state-level regulations including the MA Stretch Energy Code. Building owners must comply with all applicable federal, state, and local requirements.

      SOCOTEC also provides consulting services for the Large Building Energy Reporting Policy (LBER), a state-wide ordinance requiring disclosure of energy usage for buildings greater than or equal to 20,000 sq. ft. Reporting is due annually, beginning in Compliance Year 2025. SOCOTEC supports building owners subject to this complementary reporting requirement alongside or independently of BERDO.
