According to a report by the Vancouver Sun, Hollywood’s entertainment industry produces an average of 500 metric tonnes of CO2 per production. To put things in perspective, this is equivalent to over a hundred cars driving for year-round. While the industry is raking in billions of dollars in revenue, it’s also leaving a hefty carbon footprint.

Production studios are plagued with environmental challenges including set waste, transportation to locations, plastic food containers and water bottles as well as the chemicals used to achieve certain special effects.

Now, production companies have expressed their commitment to the fight against climate change. Sony Pictures announced that for each day of production, it will plant a tree in the community where filmings are held. It seeks to reach a zero carbon footprint by the year 2050 with a science-backed target every five years.

“It required us to bring in things like carbon emissions as a true focus,” says John Rego, VP of sustainability at Sony as per Variety.

Walt Disney Television corporate social responsibility chief Dave Ambroz said, “Sustainability really only works if there is a shift in the cultural mindset.” Disney introduced a full-time environmental steward to each live-action film production crew back in 2009. They are assigned to

“serve as the leader in environmental advocacy to educate the cast and crew on the best practices and habits to embrace as we forge our way to a greener world.”

These big Hollywood studios including NBCUniversal are part of a collaborative effort to focus on sustainability and green shooting. NBCUniversal’s sustainability director Shannon Bart says, “What’s been really cool is that that that alliance has grown to be inclusive of smaller productions and even some of the new streaming services.”
