The Sustainability Office undertakes initiatives designed to make Portland a vibrant, environmentally friendly community now and into the future. We collaborate with all departments to increase the efficiency of City operations and seek innovative approaches to improve municipal services. We partner with community organizations, citizens, and businesses working to conserve energy, reduce waste, and preserve our natural resources. We promote actions that will make Portland resilient in the face of a changing climate.

IMPORTANT UPDATES

Electrify Everything!

We are pleased to announce Electrify Everything! -- an initiative to help residents and businesses install energy efficient, electric appliances in their homes and to encourage them to adopt solar power for their energy needs. We'll use the group buying power of Portland residents to reduce costs to residents to purchase and air source heat pumps, heat pump water heaters, solar panels, and community solar subscriptions. We're organizing information about all available rebates, tax credits, and other financial assistance available to help people make this transition. Our program partner, ReVision Energy, can also help people identify affordable financing, if required. 

We look forward to helping residents reduce carbon emissions, save money, and make their homes more comfortable!

 Learn more about the program by visiting the Electrify Everything! page.

Energy Benchmarking Are Due May 1

The owners of buildings with 20,000 square feet that are occupied at least 90% by a single occupant are required to report their energy and water consumption by May 1. If you are subject to the ordinance and have not yet reported please visit our Energy Benchmarking page for information about how to comply.

New Energy Code Effective July 1, 2021

The 2021 International Energy Conservation Code (IECC) went into effect in Portland on July 1, 2021. This affects new residential and commercial construction, as well as many expansions and renovations of existing structures. Portland is the first municipality in Maine and amongst the first in the nation to adopt this code which will dramatically increase the energy efficiency of new construction and significant renovations. Implementing this code is a significant step to reach the City's goal that all new construction be net zero by 2030. We collaborated with our colleagues in South Portland to present a training session for the commercial code and the residential code presented by Kim Cheslak of the New Building Institute. Northeast Energy Efficiency Partnerships has created a number of helpful resources about the new code that is available on their website:  NEEP. Learn more about the City's climate action goals at One Climate Future.

Food Waste Composting!

We're pleased to host our food waste drop off program that helps Portland residents reduce waste by composting food scraps. Visit the location near you: North Street Community Garden, Boyd Street Community Garden, Clark Street Community Garden, Libbytown Community Garden, and Riverside Recycling. Learn more at our Compost Page.

Climate Action

The City of Portland has adopted One Climate Future, and ambitious plan to mitigate the worst impacts of climate change and prepare for those we already anticipate such as sea level rise and more extreme heat. Learn more about our efforts to reduce carbon emissions by electrifying buildings and transportation and by promoting renewable energy. The One Climate Future team holds Coffee & Climate chats that focus on different climate actions each month!

Pesticide Use Ordinance

The City Council passed a pesticide ordinance designed to protect public health and the environment by reducing chemical inputs used for maintaining landscapes. Get more information on the new pesticide use guidelines. Pesticide Applicator Reports are due February 1. 

Small changes can make a big impact.
