2050 Decarbonization Roadmap

Our Commitment

Within the power industry, PMLP has been a committed leader in environmental awareness for over 40 years. There's no reason to stop or slow down now. In fact, in recent years, humanity has become more aware of the effect of emissions than ever. So if anything, it's time to ramp up our efforts and meet these environmental concerns with equal doses of hope, determination and reason. Hope will provide us with our goals. It defines where we want to be. Reason will temper those goals with what's possible, while still being affordable and reliable. Whereas Hope and Reason can be at odds with each other, Determination will be the deciding factor. And it is with this that PMLP offers our pledge. We don't yet know what the future will bring, but PMLP will be ever-vigilant in making decisions for our customers that meet our mission statement of providing safe, reliable electricity at affordable rates, while being environmentally sustainable.

We ask that you, our customers help us along this path. It's a constant balancing act to determine the best way to meet all 4 crucial pillars of our Mission Statement. Our track record proves that we've been doing something right. We're already ahead of the curve on our path to 2050 (42% net-zero), by 2030 (59% net-zero), and all while having some of the lowest rates in Massachusetts! This is our commitment. And this is our path. We will always strive to have high-quality, reliable service at extremely low rates. And likewise, we will continue our path toward 100% net-zero carbon emissions by 2050. We believe we'll be ahead of that game, as we are now. And we pledge to keep you aware of each project as it becomes available to us.
