The circular-economy principle of ‘Reduce, reuse, recycle’ can also be applied to post-production. The French organization Ecoprod teamed up with post-production companies to create a green guide with seventy measures that were identified for the eco-friendly design of post-production workflow. Post-production averages twelve percent of the total carbon footprint of an audio-visual production.
In digital post-production, creative and technical specialists – colorists, VFX artists, post and video engineers – are involved in various stages of workflow that require powerful workstations to transfer video and audio files in networked storage systems or to render them in high resolution in real time.
When it comes to film productions, the environmental impact of the entire chain from pre-production to post-production up to the release must be assessed. Part of it is the resource and energy consumption of the devices employed. According to a 2023 study published by the French Agency for Ecological Transition ADEME, 2.5 percent of all carbon emissions and 10 percent of all energy consumption result from the use of digital devices.
As in film production, all creative and technical teams can together develop a detailed roadmap for sustainable post-production during the preparatory phase. A post-production supervisor should be named in order to coordinate and communicate sustainable measures. The energy consumption of a project can be reduced, for example, during data transmission. This requires a discussion at an early stage to determine which data formats, resolutions, and compression rates will be used.
Moreover, the energy requirements and carbon footprint of the post-production equipment has to be established. Retrofitted devices can save resources because of their extended life span. During digital data management, workflows can be optimized by using local storage for large amount of data, which is preferable to cloud-based solutions that require heavy energy consumption. The choice of digital tools and programs also has an impact on energy consumption. Opensource tools, such as Blender for 3D, Krita for illustrations, and the free audio editor Audacity are recommended.
The Latvian director Gints Zilbalodis used the free animation software Blender for the production of his award-winning animated film Flow. “Blender has a huge advantage because it‘s linked to the real-time rendering software Eevee”, says Gints Zilbalodis. “Blender and Eevee allowed me to create many variants, to try different camera angels, and to render the shot quickly to see whether it works”.
Rendering 3D models requires a lot of processing power as well as energy, which can be reduced by reusing 3D models from earlier projects. The use of GPU-based rendering engines reduces the energy consumption of the rendering process because it takes
the load off the main processor. Dubbing, post-synchronization, foley, and subtitling can be resource-intensive if the sessions take place on different days. Remote solutions can help prevent unnecessary travel. At the beginning of each project, effective metadata management, indexing, and standardized naming conventions improve file searchability and reduce redundancy.
“There are many levers in post-production that can be pulled to reduce the industry’s carbon footprint”, says Alissa Aubenque, project manager at Ecoprod. “Our green guide shows which measures can be taken so that the production of visual effects, as well as the entire post-production pipeline, can be configured to reduce energy consumption and use of resources."
“The time for half-measures and climate denial is over. Unless we move quickly away from fossil fuels, we’re going to destroy the air we breathe, the water we drink, the health of our children, grandchildren and future generations. If we’re going to avoid the worst of the impacts, then we’ve just got to act boldly. And we must act immediately."
Robert Redford

"The media has a powerful role to play in the fight against climate change. Through films, television, and all media outlets, we must continue to deliver the message that solutions are out there and are happening now. We have to make it attractive for people to take action. Movies like Avatar, The Day After Tomorrow, and documentaries like Years of Living Dangerously, which I was proud to be a part of, have been very popular, reaching and inspiring millions of people. And I believe films in particular can really inspire and make people want to take action. It’s great to see some of my film-industry friends working with climate related organizations to push forward those messages."
„It‘s high time to reorganize film production in Germany in a ‚greener‘ and more sustainable way. So far, I am flabbergasted by how much our industry works in environmentally harmful ways.To this very day, it starts with until today one-sided print-outs of scripts, and then it continues with plastic bottles in production offices and lots of plastic waste with every catered meal, and it doesn‘t stop with the limousines that pull up to a red carpet.
For many years, people have sneered at me when I brought my own cup or I declined to eat cheap meat served on paper or plastic plates with plastic knives and forks. It would be great if the Green Shooting Card could change all that.“
Director (Ben X, Time of My Life)
„It’s absolutely great that filmmakers all over the world are trying to clean up their act, and are trying to film as sustainable as we possibly can. Still, I think we shouldn’t underestimate the incredible power of the moving image to also change the hearts and minds of people.
So, apart from trying to be more environmentally aware in our business, I think the big gain lies in how we might make everyone more environmentally aware. Yes, cinema can change the world.
I think filmmakers should start using the powerful weapon in our hands that is the camera.
Let’s not only try to do ‘less bad’. Let’s try to do right, and help drive the change that we all know needs to arrive.“
“We are living in a time in which we can’t afford to behave irresponsibly towards nature. The more important is it that film productions try to work as environmentally friendly as possible. A film team produces every day tons of garbage. I try to avoid using plastic cups on set, I bring my own cup, use ecofriendly cosmetics and avoid needless single rides.”

“When we did Noah we knew we were making a film about the first steward of the earth, so we wanted to be good stewards ourselves. There’s so much waste on film sets. Because of groups like Earth Angel, we were able to change that a little bit.”
"As a TV and film producer I try to incorporate environmental storylines into my projects as much as possible. But it’s just as important, if not more, to ‚go green‘ behind the scenes! Therefore, I help run the Producers Guild of America’s Green Initiative.
We provide resources such as a Best Practices and a Carbon Calculator to help producers green their productions. We also partnered with all the major studios to create www.greenproductionguide.com which is a free green vendor database with over 2,000 vendors offering sustainable production solutions worldwide!"
‚Green screens excepted, we will do everything in our power to be as innovative as we can in order to make our production as green as possible.‘

‘It is somewhat embarrassing that green filming is only now becoming an issue in our industry because there have long since been many possibilities to shoot more efficiently.
Technical innovations such as energy efficient lighting are as much a part of this as the awareness of every crew member.’
I do work with a company in the States called Sungevity that leases solar panels to homes. They figured out how to move forward environmentally and how to make it economically successful.
So that’s my small but steadfast global contribution. I think everybody doing a little bit is all that’s made any difference, ever.‘
Producer, Director and Visual Effects Supervisor (2001: A Space Odysee, Blade Runner)
"Trumbull Studios in Massachusetts is dedicated to being green as much as possible, including the use of LED lighting, solar power, and solar laptops. This is not just because our location has limited amperage and no three-phase, we believe we have a responsibility to our community and our planet to be a clean industry.
We are planning for digital photography in 3D 4K at 120 frames per second from remote and inaccessible locations that will not have available power. Solar is the way to go."
Dieter Kosslick, Director Berlin International Film Festival
„The Berlinale is already actively addressing the sustainability subject since years. We appreciate it very much that a growing number of filmmakers, among them this year‘s jury presiden Darren Aranofsky, is following green guidelines on set.“
Benoit Delhomme
Director of Photography (A Most Wanted Man)
‘I never have been told precisely what the rules are for shooting a green movie, but we are trying to do it. This is something new for me. Sometimes people overlight scenes at night. I don’t. If I can see with my own eyes, then it is enough for the film. In that sense I am a green DoP.’
Academy Award winner Jeremy Irons who stars in the Berlinale Competition entry The Night Train To Lisbon is a fan of source segregated recycling. „Especially in Germany you have done a lot for that. You are examplary in the matter of waste separation.“
The Hollywood actor travelled around the world to promote the environmntal documentary feature film Trashed by Candida Brady which deals with the global garbage problem: „We buy it, we bury it, we burn it and then we ignore it“, says Brady. „With Jeremy Irons as our guide, we discover what happens to the billion or so tons of waste that goes unaccounted for each year.“
Since the world premiere at the International Cannes Film Festival in 2012 Trashed picked up various nominations and awards at international festivals.
