Seventeen claims that the ten-step plan will assuage the fears of events organisers overwhelmed by "something as big and scary as climate change".
The checklist can be downloaded from the agency's website and from the resources page of 10:10's site.
Andrew Williams, Seventeen Events' managing director, said: "We've been big supporters of event sustainability standards such as BS8901, but we also recognise that the most important part of the sustainability journey is the first step we all take. By producing this guide with 10:10, we're hoping to encourage industry colleagues to look at the simple changes they can make towards a more sustainable future."
Harriet Bell. the 10:10 campaign coordinator who helped produce the checklist, added: "10:10 is all about a positive approach to carbon reduction. Whilst we recognise there is plenty of hard work involved it can also be fun and provide an opportunity to be creative in the way we work.
"Events provide so much scope to put this approach into practice maximizing the creativity of those planning them and the enjoyment of those attending."
Separately, Smyle said yesterday that it had become one of the first event and production agencies to gain BS8901 accreditation - a third-party endorsement of its recently implemented sustainability management systems.
