Head of operation volunteer roles

ClientEarth is looking to add two to three new Trustees to our UK Board of Trustees.

Our Board of Trustees brings together experts from the private sector, B-Corps, non-profits and foundations, law, and the arts to guide and champion the ambition of ClientEarth in the wider environmental movement. They are driven by the urgency of the climate crisis and the relentless destruction of nature, and united in their belief in the law’s essential role in defending people and planet.

We are specifically seeking candidates with significant experience living and working in the EU or Asia-Pacific, given our depth of work in the former and rapid growth in the latter. We are also looking for candidates with the skills and willingness to take up roles on our Finance, Audit, & Investment Committee or our Governance & Risk Committee.

We are seeking outstanding people with diverse insights and experiences to help support this unique organisation in its next chapter. Will you join us?

An online Question and Answer session is scheduled for 10:30 BST / 11:30 CEST, Wednesday 5th August. Click through to the advert on our careers site to find the registration link.

Trustees also have oversight of arrangements for the appointment, supervision, support, appraisal, and remuneration of the Chief Executive Officer and the rest of the Executive Team. Day-to-day management of ClientEarth is delegated to the Chief Executive Officer, who onward delegates certain functions to the Executive Team, as well as members of the Global Leadership Group.

Further Information

UK Trustees serve a three-year term, and will be eligible for re-appointment for one additional term. In exceptional cases, or where necessary to fill a needed skill gap, a Trustee may be offered a third term.

Non-Executive Director (Board member) 

Positive Money is a leading international think tank and campaign organisation working to redesign our economic system for social justice and a liveable planet. We publish research, advocate for our proposals with politicians, policymakers, and the press, collaborate with civil society, and mobilise our community of supporters with digital campaigns. We work across six key areas: racial economic justice, finance and democracy, green finance, the future of money, housing, and macroeconomics.

We are seeking up to 4 new Non-Executive Directors (NEDs) to join the board of Positive Money UK. Our board is a non-executive body responsible for the organisation’s vision, mission, strategic direction, finances and governance. These positions are voluntary and unremunerated. Our board meets four times per year at our office in Vauxhall, and NEDs also support the organisation via membership of occasional working groups, or in reviewing policies or other documents.

We are looking for people who will bring strategic insight and either have, or wish to develop, a good understanding of governance. At a time when the funding landscape for our sector is volatile, we are also seeking people who can bring insight, experience or new connections to our fundraising efforts. We are also seeking a candidate with a strong finance background to take over from our current Non-Executive Finance Director, who will be retiring at the end of his term by the end of 2027. We are not seeking all these attributes in each candidate, and recognise that different candidates will bring different strengths and skillsets. See our application pack (link below) for full details

We are committed to diversity, equity, inclusion, and accessibility and aim to dismantle oppression in all areas of our work. If you have any questions or considerations you would like us to accommodate in the recruitment process, please contact us.

Contract: Voluntary unremunerated position

Time commitment: Attendance at four board meetings annually, including at least three in person. NEDs may also be asked to review policies, proposals or other documents for the organisation or serve on occasional working groups. NEDs generally spend 3-5 hours per month on Board work.

Deadline: Closing date for applications is 9am Mon 7th Sept with interviews held on Wed 16th Sept

There will also be an open webinar on Wed 26th August at 6pm at which some current board members and Co-ED’s at Positive Money will speak a little more about the organisation and the role, and take questions.

Start Date: We aim to appoint new NEDs formally at our Dec board meeting. We may also invite successful candidates to attend some upcoming strategy development sessions this autumn, see application pack for dates and further details.
