This class will teach teens how to use their influence as young people to lobby state legislators to pass strong climate legislation. In three hours, they will come to understand the basics of our Massachusetts legislature and the important political players, learn about the current state-level climate change bills, and practice effective communication strategies for lobbying at the statehouse. After the training, they will join other local teen leaders who recently received this training and have begun meeting with their state representatives. They will become part of a teen climate lobby movement in western Massachusetts that is demanding protection of their future!

Teens will be inspired by the example of trainer, Rep. Solomon Goldstein-Rose, currently the youngest representative in the Massachusetts state house. They will also learn tangible skills and strategies from seasoned climate activists, Adele Franks and Lilly Lombard.

We will serve a substantial, healthy, yummy snack. Class is capped at 15 students.

Climate Lobby Training for Teens is a free workshop taught by legislative activists with Climate Action Now, Adele Franks and Lilly Lombard, and Massachusetts state representative Solomon Goldstein-Rose.

Massachusetts Lobby Day for Carbon Pricing

Massachusetts Lobby Day for Carbon Pricing

June 13, 2017, 9:00am - June 13, 2017, 5:00pm

Old West Church
131 Cambridge St
Boston, MA  02114 Map

The Campaign for Clean Energy Future invites you to participate in our Carbon Pricing Lobby Day on Tuesday, June 13th! We'll meet at the office of Climate XChange (Old West Church), and then head over to the State House together.

Massachusetts is one of the only states in the country considering legislation that would put a price on carbon pollution, a policy that (if done right) will jumpstart the transition to clean energy and protect vulnerable communities.

Many climate experts say the solution to climate change is putting a strong price on carbon. That’s because making something expensive is a good motivation to get people to do it less. Right now, it’s free to pump carbon and other forms of greenhouse gas emissions into the atmosphere. But if we put a price on dumping that pollution into the our air, polluters would re-think their actions.

Right now there are two carbon pricing bills in the state legislature, and if one of them passes it would make Massachusett's the first state to price the very pollution responsible for climate change: carbon dioxide. To seize this opportunity, legislators need to hear from YOU.

Never lobbied before? No problem!
The Campaign will also be hosting a Grassroots Summit on Saturday, June 10 (location TBD) to train newcomers and talk strategy. This will provide space to prepare for the lobby day and get started on some exciting next steps. Please note that attendance at the Grassroots Summit is recommended, but not required to participate in the lobby day.

Learn more about the bills here:

Let's show Massachusetts legislators that we want bold climate action and support putting a price on carbon pollution!

Resist the Trump Fossil Fuel Agenda - Join the Billionaires Bash

Resist the Trump Fossil Fuel Agenda - Join the Billionaires Bash

May 16, 2017, 10:30am - May 16, 2017, 12:30pm


“Billionaires’ Bash” Rally to Divest State Pension Fund from Fossil Fuels

Unions, Students and Climate Groups to Rally in Boston May 16

As part of a Global Divestment Mobilization campaign, Massachusetts pensioners led by MassDivest will satirically demonstrate against the Pension Reserve Investment Management (PRIM) Board’s risky investment practices outside the next PRIM meeting. There will be billionaire puppets, artwork, a street theater skit, and a brass band. By investing $2 billion of state workers’ and teachers’ retirement funds in oil, gas and coal, PRIM is supporting the Trump agenda in Massachusetts and putting retirees funds at risk. As union leaders address the Board at their meeting, carbon investment risk expert Bob Massie will speak to the crowd outside. Afterwards, a brass band will lead the group on a march through downtown Boston to the State House where Rep. Marjorie Decker (D-Cambridge), the lead sponsor of House Bill 3281 which seeks to divest the pension funds from coal, will speak.

H.3281 would have the pension fund divest from coal and would set up a commission chaired by the State Treasurer to make binding recommendations concerning oil and gas holdings.

The mission of the MassDivest Coalition is to fight for a better future for Massachusetts retirees and citizens by divesting the state pension fund from fossil fuel companies and investing in a 100% clean and renewable energy future.

What: Demonstration outside the PRIM Board meeting

Who: Speakers Bob Massie, carbon investment risk specialist and Democratic Governor Candidate, and Rep. Marjorie Decker, sponsor of House Bill 3281; Massachusetts teachers, students, state union members, concerned citizens, actors, and members of MassDivest, a broad coalition of union, student and climate organizations, (

When: Tuesday, May 16th at 9:30 am: MassDivest address PRIM board meeting; 10:30 - street theater, music rally; 11:00 Bob Massie speaks; 11:30 Brass band procession to State House; 12:00 Marjorie Decker speaks about bill H.2381
Where: 84 State Street, Boston (9:30 - 11:15) and State House steps (12:00)

Why: To highlight the irresponsible investment practices of the PRIM Board and generate support for H.3281

Visuals: “Billionaires” dressed in colorful formal party garb; brass band playing lively New Orleans style party music, opposition chanting between “pensioners” vs. “oligarchs”

The MassDivest Coalition: The mission of the MassDivest Coalition is to fight for a better future for Massachusetts retirees and citizens by divesting the state pension fund from fossil fuel companies and investing in a 100% clean and renewable energy future.

Holyoke Community College (Leslie Phillips Theater)
Nuestras Raíces and Holyoke Community College are pleased to introduce the first annual Holyoke Food Justice Conference on May 6, 2017, at Holyoke Community College. The conference will host a diverse group of nationally-recognized food movement leaders who will share from their experiences working towards food justice and their visions for the work ahead.

At Nuestras Raíces, we are continuing to advance our work of building a sustainable and equitable food system for all residents of Holyoke and beyond. Given the current political climate, we firmly believe we must strive harder than ever to build an inclusive movement for a just, racially equitable, and sustainable food system: one that addresses privilege and access, values indigenous knowledge, and is led by, represents, and lifts up people of color and those from underserved communities. Inequity is present across the food chain, manifesting through the low wages and unfair working conditions experienced by food producers and vendors, the spread of food deserts, and unequal food access in marginalized communities. Now is the time to reclaim our food system and advance food equity through social and political change.

The conference will explore the historical roots of food inequity and evaluate our current food system. We will look at policy strategy across movements working nationwide to make our food system more equitable for all. Finally, we will share reflections on our 25 years of work at Nuestras Raíces at the intersection of food, culture, and urban agriculture in Holyoke, Massachusetts.

La conferencia será anfitrión de un grupo diverso de líderes de movimiento de alimentos reconocidos a nivel nacional que compartirán de sus experiencias trabajando hacia la justicia alimentaria y sus visiones para el trabajo por delante.

En Nuestras Raíces, continuamos avanzando nuestro trabajo de construir un sistema de alimentos sostenible y equitativo para todos los residentes de Holyoke y más allá. Dado el clima político actual, creemos firmemente que debemos esforzarnos más que nunca para construir un movimiento inclusivo por un sistema alimentario justo, racialmente equitativo y sostenible: uno que aborda el privilegio y el acceso, valora el conocimiento indígena y está liderado por, representantes, Y eleva a las personas de color y las de las comunidades desatendidas. La desigualdad está presente en toda la cadena alimentaria, manifestándose a través de los bajos salarios y las condiciones de trabajo injustas experimentadas por los productores y vendedores de alimentos, la propagación de los desiertos alimentarios y el acceso desigual a los alimentos en las comunidades marginadas. Ahora es el momento de reclamar nuestro sistema alimentario y promover la equidad alimentaria a través del cambio social y político.

La conferencia explorará las raíces históricas de la inequidad alimentaria y evaluará nuestro sistema alimentario actual. Examinaremos la estrategia de políticas a través de los movimientos que trabajan a nivel nacional para hacer que nuestro sistema de alimentos sea más equitativo para todos. Finalmente, compartiremos reflexiones sobre nuestros 25 años de trabajo en Nuestras Raíces en la intersección de la comida, la cultura y la agricultura urbana en Holyoke, Massachusetts.

Weinstein Auditorium, Wright Hall, Smith College Northampton

AWAKE, A DREAM FROM STANDING ROCK, a new documentary from directors Josh Fox, James Spione and Myron Dewey, will have a special free screening at Weinstein Auditorium, Wright Hall, Smith College. The film is subtitled for the hearing impaired and the hall is wheelchair accessible. The film will be followed by a discussion with the film’s director Myron Dewey.

AWAKE follows the dramatic rise of the historic #NODAPL native-led peaceful resistance at the Standing Rock Sioux Reservation near Cannon Ball, North Dakota, which captured the world’s attention as one of the biggest stories of 2016. Thousands of activists converged from around the country to stand in solidarity with the water protectors (activists) protesting the construction of the $3.7 billion Dakota Access Pipeline (DAPL), which is intended to carry fracked oil from North Dakota’s Bakken oil fields through sovereign land and under the Missouri River, the water source for the Standing Rock reservation and 17 million people downstream.
