It’s hard to decarbonise, unless we all do it.
NHS Wales cut emissions from buildings and transport by 23%, yet total carbon output rose 20% since 2018–19 due to supply chains

Green procurement is key to the Future Generations Act: greener suppliers mean greener healthcare

NHS Wales carbon emissions rise by 20% over past five years
The rise comes despite targets to reduce emissions by 16%, with NHS Wales blaming outside suppliers.

Critically important article finds the Windows man guilty of inventing his own reality. Science doesn’t care about wealth.
The press doesn’t get away unscathed: “The legacy media is apparently more interested in the climate musings of an erstwhile PC mogul than a sober assessment by the world’s leading climate scientists.”

Me discussing how Trump is weaponising his Justice Dept to attack his enemies

"Justice is meant to be about "here's a crime, let's find out who did it and prosecute them", but instead Trump is saying "here's the person I want to prosecute, find me the crime".

Ofgem should use firms’ windfall profits to fund energy debt relief, say MPs

The ESNZ Committee called it “completely inexcusable” that households are forced to choose between eating and heating while companies behind Great Britain’s gas pipes and power lines amass huge profits.

The world might be pulling back on climate truth: but I'm stepping it up.

How? I'm adding new videos, deep dives & behind-the-scenes stories to Talking Climate.

Why? Because climate honesty and hope matter more than ever right now.

Aged 18, all the world’s politicians promised they’d fix global warming. 33 years of adult life and we hear they shrugged, lied and walked away. I feel let down, but what about the next generation?
Overshooting 1.5°C wasn't 'inevitable.'

We've been pushed by fossil fuel giants & governments that pander to them.

Every delay, every oil field, every broken promise made this crisis worse.

Keir Starmer, will you promise to leave Rosebank undeveloped?
