Dear reader,

Around the world – from the Amazon rainforest to Australia, via Europe and North America, the Guardian’s expert network of environment reporters are working tirelessly to explore the state of our planet for readers. It's work that feels particularly important as much of the planet swelters from another relentless period of oppressive heat.

Our reporters' scientific knowledge, passion for nature in all its glory, and diverse range of contacts – from specialist academics to grassroots community movements and world leaders – is unparalleled. They find terrific scoops, produce hard-hitting investigations, help us understand what’s going on and publish clear, accessible, deeply informed journalism about the most urgent issue of our time.

Hundreds of thousands of readers have supported this vital work, telling us they want to power independent, authoritative environmental journalism that pulls no punches and is available to everyone.

Expert, hard-hitting journalism can make a difference, raising awareness of the problems – and the solutions, too. It helps put pressure on governments and businesses to make positive, urgent changes. It encourages human ingenuity and innovation. It challenges all of us to rethink every aspect of our planet – how it can be better, more sustainable, more just, and more hopeful.

The Guardian also puts its money where its mouth is. That’s why, in recent years, we have renounced fossil fuel advertising and qualified as a B Corp to hold ourselves to high social and environmental standards. By 2030, we will have completely eliminated two-thirds of our emissions. We have spelled out these editorial and institutional commitments in a climate pledge, which we report on and update each year.

If you can, please support us. You can do so for as little as €4 per month or with a one-off contribution.

Thank you,

Will Dean
