Just by becoming a member, your donations will help us to do more to get our first MPs elected.
Whatever you enjoy doing, there is always lots to help with, from writing letters to the papers, to delivering leaflets, knocking on doors, organising events and, of course, standing as a Green Party candidate.
Whatever time or effort you put in will be completely up to you.
Membership is open to everyone. You don't have to agree with every single one of our policies and, no, you don't have to pass a test!
The only requirements are that you are not a member of another party (apart from our sister Green Parties in other countries) and that you accept the party's aims to create a fair, equal and green society.
As long as you donate more than £10 a year (£5 if you are a student) this also covers your membership fee. Just answer 'Yes' to the question 'Would you like to join the Green Party' on the form when you make a donation.
We will try not to swamp you with paperwork. Most of the information you will need to stay in touch with us is available online.
When you first join, you will get a welcome pack containing a short guide to membership. Then, four times a year, you will receive a copy of our official magazine 'Green World'. There are also annual elections for national party officers and occasional mailings about important campaigns.
Your local and regional parties may also contact you with important information and ballot papers for internal elections.
We hope you will remain a member of the Green Party for many years after you join. But, if you do change your mind, you can contact us at any time to cancel your membership or your direct debit payments.
Policies are decided by our members at twice-yearly conferences. We have something to say on every subject, not just the environment. Find out more about our policies here.
You can help elect Britain’s first ever Green MPs. Caroline Lucas, Darren Johnson and Adrian Ramsay are all on the verge of getting elected.
As Green MPs, they would change the country for the better, forever. You can help make that happen.
Rejoin today online, and you’ll be contributing the biggest shake-up of British politics for nearly 100 years.
To help make being Green that bit easier, if you rejoin online by Direct Debit today, we’ll send you a free organic cotton string shopping bag to help you cut down on plastic waste.
