Executive Order No. 594 Overview

Building on the success of Executive Order 484, Executive Order 594 sets goals and requirements that will accelerate the decarbonization of fuels used to heat and cool state facilities, help to demonstrate new technologies and strategies necessary to meet the Commonwealth’s energy goals, and quicken the shift to electric heating and vehicles. By leading by example in these and other areas, state government can help guide the Commonwealth toward a cleaner future.

To help guide and measure the collective progress toward meeting these objectives, Executive Order 594 sets specific energy-related targets for Massachusetts state government between 2025 and 2050:

Targets set by the Leading by Example Executive Order, including goals to reduce emissions from onsite fossil fuels and vehicles, reduce energy use intensity, and install EV charging stations

In addition, Executive Order 594 provides directives related to state government sustainability (including demand management, water conservation, waste minimization, sustainable landscaping, and environmentally preferable purchasing), real-time energy monitoring, and data tracking and reporting.

State Partner Responsibilities

State entities covered by the Executive Order shall provide their full cooperation to the LBE Program and make every effort to support initiatives at their own facilities and collaborate with other agencies to support emissions reduction progress within state government. Specifically, state entities shall: 

  • Assess and implement strategies to mitigate greenhouse gas emissions and other environmental impacts when planning for and executing projects related to the design, construction, operations, and maintenance of state facilities, and the procurement of goods and services, including vehicles.
  • Comply with all applicable directives of Executive Order 594.  
  • Support efforts to track the energy performance of existing buildings or sites and take concrete steps to reduce building energy use through operational efficiencies. 
  • Continue to prioritize the deployment of renewable and clean energy resources to be consumed onsite or on the grid.  
  • Provide energy consumption data and other information as requested by LBE staff. 
  • Appoint LBE coordinators and participate on the LBE Council.  
  • Prioritize efforts at facilities located in Environmental Justice populations, when key fiscal, physical, and environmental factors are fundamentally equivalent.

Executive Order No. 484 (2007-2021)

Please note: The provisions of Executive Order No. 484 are superseded as of July 1, 2021, the effective date of Executive Order No. 594.

From April 2007 to June 2021, Executive Order No. 484 Leading by Example – Clean Energy and Efficient Buildings established the LBE Program and directed state agencies to prioritize practices and programs aimed to address resource use at state facilities, including a reduction in energy consumption derived from fossil fuels and emissions associated with such consumption. It set forth targets related to greenhouse gas emissions reductions, overall energy consumption, renewable energy generation, and dictated that new construction projects must meet a Massachusetts LEED Plus green building standard.

LBE progress reporting in relation to meeting the goals of Executive Order 484 will be published here when available.
