BBC, ITV or Netflix: which streaming and TV company is the most sustainable?

We scored thirteen streaming, TV and entertainment companies on sustainability, from Netflix and Disney to Spotify and Sony. Britain's public service broadcasters lead the field: the BBC, ITV and Channel 4.

The short answer: the BBC comes top with 59/100, ahead of ITV on 55/100 and Channel 4 on 54/100. Each score is out of 100 and measures what a company is doing about climate change and the environment. For comparison, 60 is where we say a company is leading, and only a handful of the 1,000-plus companies we've scored get there.

What we did

SINK is an independent sustainability score. We score every company out of 100 using the same ten questions:

• how much it emits, and whether that's falling
• how clean its energy is
• what targets it has set
• its effect on nature, water and waste
• how openly it reports
• its record on controversies

The evidence comes from each company's own reports and filings, and from independent sources such as regulators, campaign groups and the press. Every source is linked on the company's page, so you can check our work. Scores are free. Nobody can pay to change a score, speed it up or hide it.

The thirteen companies: the BBC, ITV, Channel 4, Sky, Netflix, Disney, Warner Bros. Discovery, Spotify, Sony, Tencent, Canal+, Twitch and Roku.

Who leads, and why

The three British broadcasters are the only ones making progress. The average across all thirteen is 40 today, and none has reached 60 yet.

All three have climate targets approved by the Science Based Targets initiative, which checks companies' climate targets, and all three targets are cuts in total emissions, not just per pound of revenue. For each of them, most of the footprint is in the supply chain, mostly the programmes they make and commission.

• The BBC's footprint fell from 404,102 tonnes in 2019/20 to 345,018 tonnes in 2025/26, and the emissions from its own operations are down 38%. Part of the fall comes from making fewer productions. Deloitte gives limited assurance on selected figures.
• ITV's reported footprint fell 20% in 2025, and its executive bonus scorecards include emissions targets. Much of that fall came from businesses it sold and changes of method. Its share of renewable electricity fell from 65% to 60%, short of its target of 100% by 2025; reaching that target would raise its score.
• Channel 4 has science-based targets for 2030 and 2050. Its footprint rose 2% in 2025, to 388,397 tonnes, and 99% of it is in its supply chain, mostly the programmes it commissions. Cutting that in absolute terms is what would raise its score.

None of the three publishes how much water it uses. Publishing it would raise each of their scores.

The rest of the field

• Sony scores 45/100 today, the highest outside Britain. It reports every category of its supply chain, checked by PwC, and its total footprint fell from 22.1 million tonnes in 2022 to 18.2 million in 2024. 10.2 million of that is the electricity its products use in customers' homes. Its own operations' emissions rose from 966,000 to 1,045,000 tonnes over the same years; bringing those down would raise its score.
• Netflix scores 42/100 today. The figures for its own operations are checked by EY, and it has science-based targets. But its emissions rose every year from 2023 to 2025, and its supply-chain target is per dollar of value, so the total can keep growing. An absolute supply-chain target would raise its score.
• Spotify scores 41/100 today. Its footprint rose 3.9% in 2025, its figures have no independent check, and it says its 2030 net-zero goal is under evaluation. A firm, checked target would raise its score.
• Tencent scores 40/100 today. Its music and video subscriptions sit alongside games and WeChat. Its green electricity rose from 22% to 48.5% of its use in 2025, and SGS checks its figures. But its electricity use grew 35%, to 8.67 terawatt hours, and its supply-chain emissions rose 8.7%.
• Sky is British, and scores 38/100 today. It publishes no supply-chain figure of its own, its own science-based commitment was removed from the initiative's list, and its carbon-neutral claim rests on buying offsets. The approved target it points to belongs to its US owner, Comcast, which we score separately: 39/100 today. Its own supply-chain figure and target would raise Sky's score.
• Disney scores 38/100 today. It has science-based targets for 2030, but its supply-chain emissions rose from 10.6 million tonnes in 2022 to 12.4 million in 2024. In 2025 it retired carbon credits equal to 39% of its own operations' emissions, and it has four more cruise ships planned from 2027 to 2031.
• Warner Bros. Discovery scores 34/100 today. Its total footprint fell 18% in 2024, but its own operations' emissions rose 22%. Its figures have no independent check and its targets have no science-based approval; both would raise its score.
• Canal+ scores 31/100 today. Its footprint counts six of the fifteen supply-chain categories, leaving out the content and sports rights it buys. France's broadcasting regulator fined its news channel, CNews, for unchallenged climate-science denial, and the Conseil d'État upheld the fine in November 2025.
• Twitch scores 28/100 today. It publishes no environmental reporting of its own. It is owned by Amazon, which we score separately: 27/100 today.
• Roku scores 20/100 today. It sells streaming players and TVs, but publishes no sustainability report, no emissions figures and no climate targets. A first sustainability report with emissions figures would raise its score straight away.

A couple of notes

• Some scores are for the whole group. Sony's covers PlayStation, music and films, and also its cameras, TVs and image sensors. Disney's includes its theme parks and cruise line. Warner Bros. Discovery, Tencent and Canal+ are also scored at group level.
• Sky's score is for Sky UK, which covers the UK and Ireland. Comcast, its owner, has its own score.
• ITV and Roku are covered by only two independent sources so far. Their pages say so, and their scores may change as more evidence appears.
• Twitch was last scored in April 2026, under an earlier version of our method. Its page says so.
• Scores can go down as well as up. When companies publish new reports, we score them again.
