Partnership Project is a left-of-center environmentalist advocacy group that consists of a collaboration of 20 environmental groups, including some of the largest environmentalist organizations in the country. It is governed by a 20-member board of directors and a 10-member executive committee. 
The Partnership Project manages the Save Our Environment Action Center website, a collaboration of various groups that utilize the internet for environmentalist activism. 
Protect NEPA (referring to the National Environmental Policy Act) is a campaign of the Partnership Project. The National Environmental Policy Act (NEPA) is a law passed in 1970 that is used as a framework to protect the environment on key federal actions. The Protect NEPA campaign is a coalition of left-leaning environmentalist and civil rights advocacy groups, including Sierra Club, Defenders of Wildlife, and League of Conservation Voters, that attempt to advance and protect the NEPA. 
The campaign focuses on the left-leaning issue of climate change. Through Partnership Project’s Protect NEPA campaign, it denounces President Donald Trump and his administration’s handling of environmental issues.  It has accused the Trumps administration of taking measures to weaken the NEPA and that will result in massive oil spills and environmental catastrophes.  Defenders of Wildlife, a left-leaning organization involved with Partnership Project, has accused President Trump of giving public lands to private interests. 
Climate Action Campaign
Partnership Project created the Climate Action Campaign, an unbranded coalition of environmentalist groups, state and local partners, and allies that promote an aggressive left-wing policy approach to combatting climate change.
Climate Advocacy Lab
Climate Advocacy Lab is a Partnership Project campaign. Climate Advocacy Lab helps climate-change and environmentalist-energy advocates create and run campaigns by providing support, data, and other tools needed. It offers its member groups an online platform to find research and experimentation results.  In November 2018, Partnership Project received a grant of $200,000 specifically for the Climate Advocacy Lab from the William and Flora Hewlett Foundation. 
Methane Partners Campaign
Methane Partners Campaign, a campaign by Partnership Project, claims to advocate for nationwide methane pollution standards by defending and implementing regulations within the oil and gas industry. There is little information available on the campaign and it has no website. In November 2017, Partnership Project received a grant of $700,000 for both the Climate Advocacy Lab and Methane Partners Campaign from the Hewlett Foundation. 
Partnership Project claims to be an environmental advocacy group, however, many of its allocated grants do not focus on the environment or climate change, but are given to left-progressive organizations, groups, and unions focused on medical reform, voter turnout and voter education, poverty, and progressive initiatives.

Partnership Project Coalition Members Donations
Of the 19 Partnership Project coalition members, nine received grants from Partnership Project in 2017, while Partnership Project received grants from coalition members. Partnership Project’s largest donations, some exceeding $800,000 were given to fellow partner organizations. Most of Partnership Project’s grantees in 2017 received under $100,000; however, the largest amounts were given to coalition members, while lesser amounts were given to non-coalition members.
Many coalition members received grants from Partnership Project and in the same year Partnership Project received money from those same groups. In 2017, Partnership Project allocated $123,450 to partner group Natural Resources Defense Council (NRDC), and NRDC allocated $540,000 to Partnership Project.  This practice occurred with several other coalition members, including Environmental Defense Fund (EDF) and the League of Conservation Voters. Environmental Defense Fund received $303,093 and Environmental Defense Fund – Mom’s Clean (an arm of EDF) received $315,936  from Partnership Project, while Partnership Project received $530,000 from EDF.  League of Conservation Voters received $851,033 from Partnership Project, while Partnership Project Action Fund, an arm of Partnership Project, received $2.5 million from the League of Conservation Voters in 2017. 
Of the nine coalition members, many organizations allocated monies to fellow members, for example, NRDC received grants from EarthJustice, Partnership Project, and National Wildlife Federation.  Sierra Club received money from NRDC, Wilderness Society, and Partnership Project.  The League of Conservation Voters received money from Sierra Club, EarthJustice, NRDC, National Wildlife Federation, and Partnership Project. 
The coalition members all identify as organizations that advocate for environmentalist issues or animal liberation welfare, however, at least half of the members granted monies to organizations and groups that are active in broader left-leaning advocacy work, including medical reform, voter turnout and voter education, poverty, and progressive initiatives. Coalition members donated to the same outside groups, including Taxpayers for Common Sense, Hip Hop Caucus, Mi Familia Vota Education Fund, and Virginia Organizing.
