Climate change is arguably the most significant issue facing the world right now. So you’d be forgiven for thinking this is an issue on which it would be easy to hold politicians to account. But you'd be wrong.

DeSmog collaborated with the Guardian to analyse which of the UK’s MPs have the best and worst records on climate change. We’re very pleased with the Guardian’s climate score league table, and think it offers a fair reflection of where most MPs sit on the issue — today and over the past decade. 

With Boris Johnson (who scores terribly, by the way) poised to call a general election as soon as Parliament will let him, and more people than ever caring deeply about climate change, now seemed like the perfect time to do the analysis.

The BBC has altered its editorial guidelines after persistent calls for the organisation to improve transparency around the commentators to which it gives a platform.

The broadcaster has now added “think tanks” to a list of groups that it says presenters and producers should “not automatically assume … are unbiased”.  “Appropriate information about their affiliations, funding and particular viewpoints should be made available to the audience, when relevant to the context,” the guidelines say.

The change could have significant ramifications for representatives of anti-regulation, pro-Brexit think tanks and campaign groups based in and around offices at 55 Tufton Street, including the UK's principal climate science denial campaign group the Global Warming Policy Foundation, on which DeSmog has extensively reported.

A network of lobbyists, politicians and campaign groups is pushing the UK towards a hard-Brexit, with the aim of axing environmental protection in the name of free-market ideology.

Powerful vested interests are at play, with a network of decision-makers and companies that profit from climate inaction overlapping with a cabal of climate science deniers eager to limit global action to cut emissions.

Over the past four years, DeSmog has been tracking this network. We’ve now mapped over 2,000 connections between its actors operating at the highest levels of political and corporate life in the UK, US and Europe.
