The European Commission is asking that question as part of a new photo competition.

And we know our biotech and science readers in Europe will be keen to show off the green credentials of their labs and working environments. Researchers and science enthusiasts who want to take part should upload their photo by 19 October for the chance to win a 2-day paid trip to Berlin, where they will visit the ARTEFACTS exhibition, led by artist and competition judge,  J Henry Fair. The public will also help decide on the best #GreenLabEU pic by voting via the EU Science Hub – Joint Research Centre Facebook page.

Upload your photo now – the winner will be revealed on 29 October.
