Given the rise in disinformation and the shift towards destructive far-right ideologies, I’ve decided to step away from X.
While my profile will remain visible for now, I will no longer be active here.
I’ll continue sharing updates around positive climate action and the work cities are doing to tackle the climate crisis on Bluesky and LinkedIn - platforms where I believe we can build more inclusive and compassionate communities.
I hope to connect with you there.

1/ We know that any price rise is a concern for families. Wholesale gas prices remain 75% above their levels before Russia invaded Ukraine. That is the fossil fuel penalty being paid by families, businesses and our economy.
Readers added context they thought people might want to know
Figures provided by Ofgem show that the wholesale gas price in the UK is now actually below the level it was prior to Russia invading Ukraine in February 2022.

BP's climate U-turn could cause over 400,000 deaths by 2050. This is not a business decision - it's a public health catastrophe.
The era of fossil fuels must come to an end.

Climate action is not incompatible with economic transformation.
Instead, they are inextricably linked, argues @MarkWatts_ of @c40cities.
Pope Francis was a true global leader whose commitment to climate justice has inspired millions. On behalf of C40 Cities, I extend our deepest condolences and reaffirm our dedication to the urgent climate action he so passionately championed.
From his groundbreaking Laudato si’ encyclical in 2015 to his championing of local communities and urgent call for action in Laudate Deum, Pope Francis consistently reminded world leaders of their responsibility to protect our planet, the vulnerable, and future generations.
His message resonated strongly with mayors and city leaders who were honoured to meet the Pope on several occasions, most recently at the Vatican climate summit in May 2024.
Pope Francis’s leadership will continue to inspire us as we work to create a sustainable, fairer world.

It's inspiring to see C40 Co-Chair & @MayorofLondon @SadiqKhan and Governor of Nairobi @SakajaJohnson working collaboratively to address the climate crisis, and foster closer ties.
Together, city leaders can spearhead the urgent climate action the world needs.
Global cooperation on the climate crisis has never been more important. I was delighted to welcome the Governor of Nairobi Johnson Sakaja to City Hall today and discuss how our cities can work more closely together to reduce the impact of the climate emergency.

Great to plant a tree as part of #FreetownTheTreetown - where residents earn tokens to plant and monitor trees.
So far over 1.2 million trees have been planted - helping strengthen resilience & reduce carbon emissions.
A brilliant example of climate action delivering economic & environmental benefits.
Climate action needs collaboration.🤝🇸🇱
This week in Freetown, I’ve had the opportunity to meet with @VP_Jalloh, Deputy Minister of Local Government and Community Affairs Hon. Alfred Moi Jamiru, Alexandra Maclean, Development Director @FCDOGovUK and the national media of Sierra Leone.
We’ve discussed the important progress being made on climate action in the region and Freetown’s leadership in addressing the climate crisis.
Great to be in Freetown this week - thank you for the warm welcome @FCC_Freetown.
Freetown welcomes @c40cities Executive Director @MarkWatts_. The visit underscores our shared commitment to climate action, sustainable urban development, and resilience. We look forward to impactful discussions and collaborations! 🌍
I’m excited to be in Freetown- a city leading the way on climate resilience.
It’s great to spend time with Mayor @yakisawyerr. Thank you for the warm welcome.
This week, I’m meeting leaders to strengthen partnerships & visiting climate projects driving real impact.
Air pollution isn’t just an environmental issue - it’s a public health emergency claiming over 8 million lives annually.
We need national governments to step up to ensure the right to clean air is afforded to all.
Speaking on behalf of C40 Co-Chairs @MayorofLondon and @yakisawyerr, @metecoban92 spoke at the @WHO Conference on Air Pollution and Health.
By putting people at the heart of clean air action, city leaders can create healthier, thriving places to live, play and work.

ALT A quote card from Mayor of Freetown, Yvonne Aki-Sawyerr and Mayor of London, Sadiq Khan which reads: "Breathing clean air is not a luxury—it’s a fundamental human right that should be accessible to everyone, everywhere. We recognise that air pollution is not just an environmental crisis—it is a public health emergency and a matter of justice."
Congratulations to @MikeBloomberg for making @TIME's 2025 Earth Awards list.
At C40, we are honoured to work alongside you to advance climate action and fight for a sustainable future for all.

Cities are at the forefront of tackling the climate crisis - but they need the best available evidence to drive real change.
The latest special issue of the Journal of City Climate Policy and Economy is led by cities and features case studies and analysis from multiple sectors and regions and how on-the-ground action can shape policy and inform science.
📖 The latest issue of the Journal of City Climate Policy and Economy is here.
Research and city practitioners connect and share the knowledge and approaches needed for cities to meet their climate goals.

Brilliant to see C40 Co-Chair @MayorofLondon backing initiatives that safeguard the future of football and the health of our cities.
#NFFC @_greenfootball
Football has the power to change the world and now it’s taking on the climate crisis. Great campaign from @_greenfootball.
Very concerning to see the arrest of the Mayor of Istanbul @imamoglu_int. @annehidalgo.bsky.social & many other mayors are calling for his release
