The role of treasurer is to maintain ongoing involvement in the organisation’s financial management and represent the trustees on financial matters. This includes regular oversight of the finances, assisting staff in ensuring that Green Alliance fulfils its financial obligations, and advising staff and trustees on financial policy and strategy.

In addition to the wider responsibilities of a trustee (see below), the duties of the treasurer include:

• Providing direct support and advice to the operations director and executive director on financial matters, as required.
• Maintaining an understanding of the overall financial picture and attending quarterly board meetings to report to trustees.
• Understanding the implications of Green Alliance’s policy and business plans on the finances.
• Making recommendations and advising staff and trustees on financial strategy, to maximise resources, minimise risks and improve performance.
• Presenting the audited accounts to trustees at the AGM.
• Chairing meetings of the finance and management committee (see below).
• The role of treasurer requires some additional time commitment, compared to other trustees, at around eight to ten days a year.

Finance and management committee

The finance and management committee meets online a week before quarterly board meetings. It oversees administrative and financial activities. It has no delegated authority but makes recommendations to the board. It has up to five members, who are Green Alliance trustees, nominated by the board at its AGM, one of whom will be the treasurer. An agenda is produced for each meeting. The outcomes of meetings are reported to the board, including advice on policy and items of information. Minutes of each meeting are produced and circulated to all trustees. Members of the committee also provide ad hoc advice to staff between meetings, as and when necessary.

What the board does

The whole board meets once every three months for two hours, in addition to an annual board dinner and strategy session. Trustees are encouraged to attend meetings in person at Green Alliance’s office, in Millbank Tower, SW1, but are able to join the meeting via Microsoft Teams when necessary.

Trustees read the board papers in advance of the meeting and come ready to contribute questions and comments. A couple of times a year we invite staff to join trustees for refreshments at the office before the board meeting, and some of the team give a brief overview of work they have led. This gives great insight into the work taking place and helps bring topics covered in the board papers to life.

In addition to the quarterly board meetings, trustees may be part of smaller working groups for designated periods. Trustees are also encouraged to attend Green Alliance events, including our annual summer reception.

Trustees serve an initial term of three years, which can be renewed up to a maximum of nine years.

We’re committed to diversifying

We need a diverse and inclusive board to lead Green Alliance effectively. We know that including different perspectives, experience and expertise will enrich our conversations and help us make better decisions.

We encourage applications from people of all backgrounds, particularly from candidates who are under 35, people of colour and those who will increase the socioeconomic diversity of our board.

We are open to applications from people who have not served on a board before and will offer mentoring and support in skills development to enable full participation as a trustee. We understand that people can have different needs and will always work to accommodate them.

You can read more about our emphasis on equity, diversity and inclusion on our website.

What do trustees do?

The board of trustees is responsible for making sure that Green Alliance fulfils its purpose. They support and hold to account the executive director and the senior management team. Together, Green Alliance trustees:

• ensure the organisation pursues its objectives, manages its resources effectively and complies with its governing document, charity law, company law and other relevant legislation and regulations;
• contribute actively to the board’s role in determining the strategy of the organisation and setting the mission, purpose and priorities of Green Alliance and safeguarding the organisation’s ethos and values;
• offer advice and assistance to the chair, other trustees, executive director and staff;
• share contacts that could be relevant and beneficial to Green Alliance in the pursuit of its charitable aims;
• represent the organisation and participate in its activities, as appropriate.

You can find out more about what it means to be a trustee on the Charity Commission’s website.
