Building Decarbonization & Building Decarbonization

In Massachusetts, Rhode Island, and most other states, the building sector is second only to transportation in terms of greenhouse gas (GHG) emissions. For states that have already passed laws committing to serious GHG reductions, there is no way to avoid making a timely transition to clean heat (i.e. switching from methane, heating oil, and propane to electrification).  

But what’s a decarbonizer to do, exactly? Let's assess some of the options that are on the table for state governments. Spoiler alert: These are all excellent policies, but each one is insufficient. None of them are capable on their own of reducing building sector emissions 50% by 2030 or to net zero by 2050. But together they can.

Two states & their Decarbonization challenges

Rhode Island and Massachusetts both have mandates to reduce statewide greenhouse gas (GHG) emissions by 2030 compared to 1990 levels: 50% for Massachusetts and 45% for Rhode Island. Let’s take a look at the approaches they’re taking in the building sector, specifically – what they have in common, what’s different, and what might work.

Is Mass Save capable of phasing out natural gas?

Massachusetts and Rhode Island have both committed to reducing greenhouse gas (GHG) emissions economy-wide to reach net-zero emissions by 2050. Achieving these required reductions means zeroing out emissions associated with heating our homes and businesses, which means phasing out the combustion of fossil fuels for heat.

Our two favorite states have had nation-leading energy efficiency programs for many years and those programs have saved an impressive amount of electricity, heating oil, propane, and natural gas. But are these programs up to the task of actually phasing out fossil fuels by 2050?

Why We Need a (Good) Clean Heat Standard – a message for Massachusetts & Rhode Island

Energy standards have changed our electricity and auto industries for the better. Now it’s time to bring the same idea to how we heat our buildings.

What the Inflation Reduction Act Means for Massachusetts & Rhode Island

On August 16, President Biden signed into law the Inflation Reduction Act (IRA), the largest investment in fighting climate change on the national level this country has ever seen. The IRA is a huge deal and fundamentally changes the game for our work here at the state level. On August 31, we held a webinar to discuss the IRA and its impact on three levels: on individual consumers who want to go green, on towns and cities, and on the state. Here is the webinar recording, as well as a summary and clips of each individual section. Enjoy!

We Like the Massachusetts Climate Bill. The Governor Must Sign It.

On Thursday, the Massachusetts House and Senate both passed a major new climate bill, An Act Driving Clean Energy and Offshore Wind. The legislation now goes to Governor Baker for signature. The bill is basically what we expected: a combination of the House’s emphasis on offshore wind, the Senate’s emphasis on electric transportation, and some new policies in other areas. Overall, we are very pleased with the 96-page bill. Here are our views on some of the key provisions – and what you can do to get this over the finish line. 

How to "Shave the Peak" when the electric grid is dirtiest

Peak Alerts! Protect our climate by reducing your electricity use on weekdays from 5-8pm

Starting Tuesday, July 19th, 2022

According to Accuweather, we're headed for a prolonged stretch of hot weather through July 31st. Over the next few days, you might hear from your local utility or our electric grid operator, ISO-New England, that our electricity system will be stressed. If you care about air quality and the cost of electricity, the next two weeks are a time to pay attention to when you're using energy. In this blog, we’ll explain how weather affects the power grid, and how we can collectively try to cope.

Buildings in the Massachusetts Clean Energy & Climate Plan

This blog covers strategies outlined in Massachusetts’ final Clean Energy and Climate Plan (CECP) to reduce greenhouse gas (GHG) emissions in the buildings sector. For more background on the CECP for 2025 and 2030, read this blog.

Residential and commercial heating and cooling contributed 29.5 million metric tons of carbon dioxide equivalents to Massachusetts’ emissions in 1990, or about 15% of total GHG emissions. The newest draft of the state's Clean Energy and Climate Plan (CECP) now calls for a 49% emission reduction by 2030 relative to 1990 in the heating sector (virtually the same percentage decrease as the economy-wide target of 50%).

For the last several years, we have seen emissions fall significantly from within the electricity sector, while building emission reductions have been more stubborn. Here’s what the CECP says we’re going to do about that, and our take on those strategies.

Cracking the Code on Building Sector Emissions

On February 8, Massachusetts energy officials proposed regulations that would require new residential and commercial buildings to be significantly more energy efficient. The proposal would establish a new energy code statewide, in addition to a more rigorous “stretch code” that cities and towns can adopt.
