of the COVID-19 pandemic. In response, the BBC was targeted by "Chinese trolls and fake news websites", which cybersecurity company Recorded Future says are "likely state-sponsored", claiming the broadcaster had applied "a gloomy or 'underworld' filter" to the imagery in its reports to make the country look "dull and lifeless". Foreign Affairs ministry official Zhao Lijian and Chinese state media outlets have repeated allegations of a "gloom filter." The Global Times posted a comparison between the Chinese version and English versions of the BBC video, pointing out a difference in coloration between the two. Organizational practices Climate change The BBC has been criticised for hypocrisy over its high carbon footprint despite the amount of coverage that it gives to the topic of climate change. Newsnight presenter Jeremy Paxman argued that its correspondents "travel the globe to tell the audience of the dangers of climate change while leaving a vapour trail which will make the problem even worse". Paxman further argues that the 'BBC's coverage of the issue abandoned the pretence of impartiality long ago'. At the 2007 Edinburgh International Television Festival, Peter Horrocks, the head of television news, and Peter Barron, the editor of Newsnight'', said that the BBC should not campaign on climate change.

In July 2011 a BBC Trust review cited findings of an assessment by Professor Steve Jones of University College London. Jones found there was sometimes an "over-rigid" application of the editorial guidelines on impartiality in relation to science coverage, which failed to take into account what he regarded as the "non-contentious" nature of some stories and the need to avoid giving "undue attention to marginal opinion". Jones gave reporting of the safety of the MMR vaccine and
