We could start plant trees at the conferences. it's also a nice social event. You can ask people who enroll if they want to pay the cost of a tree (you know CO2 footprint of a plane) and than they can plant it, with a picture. And you can also  put a bed of organic residues of food left overs from waste sorting as compost.

I see from:   https://meta.wikimedia.org/wiki/Sustainability_Initiative that: <quote> On February 24, 2017, the board of trustees of the Wikimedia Foundation adopted the following resolution as a result of this initiative: The Wikimedia Foundation is committed to seeking ways to reduce the impact of our activities on the environment. We aim to always act responsibly and sustainably as possible, including favoring renewable energy for our operations. We believe that a long-term commitment to sustainability is an essential component of our work towards the Wikimedia mission and vision.To this end, the Wikimedia Foundation makes the following commitments: * We will seek to minimize our overall impact on the environment; * We will consider sustainability as an important part of decisions around servers, operations, travel, offices, and other procurement; * We will use green energy where it is available and financially prudent; and * Starting in 2018, we will include an environmental impact statement in our annual plan. </quote> for example: * use cotton (not plastic) lanyards; or avoid lanyards altogether * don't give away cheap plastic pens, etc. * avoid bottled water, where tap water is potable, otherwise use glass bottles * avoid sandwiches in plastic (or plastic-lined) packs * avoid disposable cutlery and plastic plates * ensure waste is collected, appropriately sorted and recycled How can we build this into our movement? Should it be a consideration in assessing grant funding applications? Would a more specific resolution from the board help? Who at WMF has oversight responsibility for these issues? -- Andy Mabbett @pigsonthewing http://pigsonthewing.org.uk _______________________________________________ Wikimedia-l mailing list, guidelines at: https://meta.wikimedia.org/wiki/Mailing_lists/Guidelines and https://meta.wikimedia.org/wiki/Wikimedia-l New messages to: Wikimedia-l(a)lists.wikimedia.org Unsubscribe: https://lists.wikimedia.org/mailman/listinfo/wikimedia-l, <mailto:wikimedia-l-request@lists.wikimedia.org?subject=unsubscribe>
