You can be an agent of change; to responsibly, over time, radically reduce the carbon footprint.

Over a seven-year period, JCAN’s goal is to lead Jewish institutions to achieve radical, deep energy savings, and to inspire the entire Jewish community to do similarly in homes and businesses.

JCAN is developing resources and guidance for congregations and institutions. Every group of people, every physical plant, every financial situation will pose a different set of issues. And JCAN looks forward to the interchange of ideas as we go forward.

But together, in the spirit of כלל ישראל (Klal Yisrael, a community of Jews working together) and remembering the sanctity of all creation, we can achieve the deep reductions in energy usage critical to the future, for ourselves, and our children.

It is not beyond us. We can do it, and we must do it.

Portfolio Manager program

When you are ready to "get serious," JCAN recommends enrolling your facility in the Energy Star "Portfolio Manager" (PM) program run by the U.S. Environmenal Protection Agency. It is excellent, free, and used widely by many different building types across the country.

A big advantage of Portfolio Manager is that you can use it to manage carbon reductions. As you make changes in your building, you will readily see the results. Portfolio Manager requires much of the same data that you used for the MIP&L benchmarking spreadsheet, so you need only a bit more effort to get started. After the initial setup, enter data as you will -- perhaps when each utility bill is received, or monthly, or quarterly.

Whose job is this? It can be a volunteer or a committee, but the tool is valuable only when it continues to be used over time.

Many helpful guides and tutorials can help you use Portfolio Manager.

Another tool is EPA’s "Energy Star Congregation" goal. Any congregation can aim to achieve this level of efficiency. For recognition, you must at least be enrolled in Portfolio Manager. Upon setup in PM, you are given a score which compares your congregation to all others in the program. You become an "Energy Star Congregation" if and when you earn a score of 75 or higher, indicating that your facility performs better than at least 75 percent of similar buildings nationwide.

This recognition level has been achieved by only 50 congregations nationally as of Aug 2015. Only three of them were Jewish, and these were not in Massachusetts.

Energy Star provides other resources directed particularly at congregations: the 2014 Feb. EPA ENERGY STAR Action Workbook for Congregations and Appendices.

In order to fully transform your community in a world-sustaining way, Jewish Climate Action Network suggests the following eight areas of assessment and examination for making incremental changes over a period of time. Jewish texts are provided for each one.

The JCAN Bentshmarking Campaign, launched in 2015/5776, begins by focusing on an institution’s energy usage and education. If it doesn’t work for your organization to start with energy, the holistic approach to benchmarking offers additional opportunities.

Energy usage

What is your institution’s current carbon footprint in terms of the energy consumption of the building? How much gas, oil, and electricity do you use each year?

When in your war against a city you have to besiege it a long time in order to capture it, you must not destroy its trees, wielding the ax against them. You may eat of them, but you must not cut them down. Are trees of the field human to withdraw before you into the besieged city? (Deut. 20:19-20)

R. Zutra said: He who covers an oil lamp or uncovers a naphtha [lamp] infringes the prohibition of wasteful destruction. (BT Shabbat 67b)

Just as we have a moral obligation not to profit from industries that use slave labor; create, market or import addictive drugs; or do other activities we perceive as destructive to society, so should we not profit from the fossil fuel industry. Although we are not going to starve them of funds, we can delegitimatize such activity.  If our culture is to avoid a climate catastrophe 80% of all fossil fuel reserves must remain in the ground. The Saudis understand this and that is why they are pumping like mad to wring as much as they can from their reserves before oil becomes a stranded asset. The result is that that oil is now selling for less than $40/barrel.

By excluding fossil fuel and related industries from our personal and institutional investment portfolios we not only reduce the amount of carbon we directly contribute to the atmosphere but we also protect our portfolios from the inevitable loss of value of these reserves on which the industry bases its stock prices.

Where are your assets invested? How much of your financial portfolio is invested in the fossil fuel industry, whether it is your own institution’s investments or the larger community’s?

The earth is the Lord’s and all that it holds, the world and its inhabitants. (Ps. 24:1)

Raba said: When a person is brought for judgment on Judgment Day he is asked 'Did you do your business honestly…’ (BT Shabbat 31a)

Food and Waste Stream

What is the carbon footprint of your food consumption and waste production? How close to being a zero waste production institution are you? Paying attention to the food in your institution is another way to reduce its carbon footprint. In addition, you can insure that everyone who enters eats food that is kosher (literally “fit”) in ways that go beyond a traditional hechsher or certification.

See above regarding energy usage.

Rabbi Simeon bar Yohai taught: This may be compared to the case of men on a ship, one of whom took a borer and began boring beneath his own seat. His fellow travellers said to him: "What are you doing?" He replied, "What does it matter to you - am I not boring under my own seat?" They said, "[It matters to us] because the water will come up and flood the ship for us all." (Midrash Rabbah, Vayikra 4:6)

Hazon, a national Jewish food organization, provides the tools you need. Its Food Audit is an easy-to-use assessment tool that helps you to:

  1. Identify the strengths and weaknesses of your institution’s policies and practices for promoting food sustainability and justice in seven main categories.

  2. Develop an action plan for improving your institution’s food sustainability and food justice policies and practices.

The Food Guide, a companion to the Food Audit, has chapters on the same seven categories assessed in the Food Audit and provides an abundance of information and resources.

If you have any questions or concerns, Hazon provides the support you need.

How do people get to and from your synagogue? How widespread is carpooling? What encouragement is given to using public transportation, walking, and bicycling to and from events?

What is the reason [olive trees and grapevines were not burned in the Temple fires]? It is not because they are ash producing. It is because they make too much smoke. (Rabeinu Gershom to Babylonian Talmud Tamid p. 29b)

Ten things were said in Jerusalem: One cannot make [large] ovens in the city...because of smoke... (Babylonian Talmud, Bava Kama, p. 82b)

Carcasses, graveyards and tanneries (which are all sources of noxious odors) must be distanced from the city at least 50 cubits… (Babylonian Talmud, Bava Batra, p. 25a)

How viable and diverse is the ecosystem surrounding your building(s)? To what extent does your property provide a carbon sink to offset your carbon usage? To what extent does it contribute to your sustainability?

If along the road, you chance upon a bird’s nest, in any tree or on the ground, with fledglings or eggs and the mother sitting over the fledglings or on the eggs, do not take the mother with her young. Let the mother go, and take only the young, in order that you may fare well and have a long life. (Deut. 22:6-7)

You shall not kill the mother and its young both in one day (Lev. 22:28). The reason for both [commandments] is that we should not have a cruel heart and not be compassionate, or it may be that Scripture does not permit us to destroy a species altogether, although it permits slaughter [for food] within that group. Now the person who kills the mother and the young in one day or takes them when they are free to fly, it is as though they have destroyed that species. (Ramban, Moses ben Nachman, Nachmanides)

The ultimate key to our society moving off of fossil fuels is systemic change. How frequently do members of your community engage in advocacy around issues related to climate change? How frequently do they advocate or take other political actions related to climate change together, as a community?

All who can protest against [something wrong that] one of their family [is doing] and does not protest, is held accountable for their family.[All who can protest against something wrong that] a citizen of their city [is doing and does not protest], is held accountable for all citizens of the city.[All who can protest against something wrong that is being done] in the whole world, is accountable together with all citizens of the world. (BT Shabbat 54b)

How knowledgeable are members of your community and your community as a whole about the climate crisis? How often is the climate crisis discussed within your community? What connections can community members make between Jewish teachings and climate change?

You shall love the LORD your God with all your heart and with all your soul and with all your might. (Deut. 6:5)

When a person observes God’s works and God’s great and marvelous creatures, and they see from them God’s wisdom that is without estimate or end, immediately they will love God, praise God and long with a great desire to know God’s Great Name. (Mishneh Torah, Sefer Madah, Hikhot Yesodei Ha-Torah 2:1-2)

Teach them to your children. (Deut. 6:7)

Just as a person is obligated to teach his child, so, too, is he obligated to teach his grandchild, as (Deut. 4:9) commands: "And you shall teach them to your sons and your grandsons." [Furthermore, this charge is not confined] to one's children and grandchildren alone. Rather, it is a mitzvah for each and every wise man to teach all students, even though they are not his children, as (Deut. 6:7) states: "And you shall teach them to your sons..." The oral tradition explains: "Your sons," these are your students, for students are also called sons, as (II Kings 2:3) states: "And the sons of the prophets went forth." (Mishneh Torah, Sefer Madah, Hikhot Talmud Torah 1:2-3)
