Protecting the ocean is essential to protecting our future.

🌊 Today, we announced a new $260 million commitment to expand the Bloomberg Ocean Initiative.

This support will help create new marine protected areas, strengthen fisheries management, protect coral reefs, and support community-led conservation efforts around the world — advancing the global goal of protecting 30% of the ocean by 2030: https://t.co/MKspgiWjWW

With air quality data from @breathecities, mayors around the world have reduced pollution near schools, expanded clean transit, cut building emissions, and taken other steps that are improving the health of millions of people.

Today at #LCAW2026, @bloombergdotorg announced a new $45 million investment in Breathe Cities to build on that progress and welcomed Addis Ababa, Ethiopia, and Madrid, Spain to the network.

#LCAW2026 is off to a great start 🇬🇧

One of the highlights of my first day in London was meeting with remarkable women leaders from the @UN Women Rise for All Network, including @annemarie_hou, @anthawilliams, Mary Schapiro, @citylordmayor, @LaurenceTubiana and more. The solutions they’re advancing to create a more sustainable future are making a real difference in communities around the world.

"People want to live in cities with clean air and, where people want to live, businesses want to invest."

@MikeBloomberg has exciting plans for what's set to be the biggest London Climate Action Week yet. Stay tuned for more this week!

Cleaner air. Lower emissions. More jobs.

Climate action and economic growth go hand in hand.

As @TheTimes reports, I'm in London for #LCAW2026. https://t.co/u3EEEzDuRV

This week at the #OurOcean Conference, 16 countries committed to combat IUU fishing through the Mombasa Declaration.

I teamed up with Emelia Arthur, Ghana's Minister for Fisheries & Aquaculture, to write about what this call-to-action means in practice. https://t.co/P6kMzNZMEt

🪸Coral reefs are not doomed.

For years, the story has been inevitable loss. New science says some reefs have a chance to survive, with policy and investment, write WCS's Stacy Jupiter and @MelissaW_Enviro of @BloombergDotOrg.

Progress is happening - and it’s being led by cities and communities around the world.

This #EarthDay, we’re spotlighting how @BloombergDotOrg and our partners are protecting the environment.

[Mike Bloomberg @MikeBloomberg]

🌎 Earth Day reminder: Climate leadership is built from the ground up.

From city halls to neighborhood blocks, climate action is delivering immediate benefits: cleaner air, healthier communities, and stronger economies.

[Antha N. Williams @anthawilliams]

Over the last year, I've had the privilege of exploring some of Earth's most magnificent oceans, forests, & mountains with family & friends.

For #EarthDay, I'm sharing some of my favorite photos – a small reminder of what we're fighting for & what makes this work so meaningful.

[Patti Harris @PattiHarris]

Urgency. Optimism. Innovation. 🌎

That’s what it takes to protect our planet — and it’s exactly what this year’s @EarthshotPrize winners bring. Congratulations to these inspiring changemakers — we can’t wait to work with them to grow their bold ideas and drive lasting impact. 💚

[Bloomberg Philanthropies @BloombergDotOrg]

📍This week in Rio de Janeiro, local climate leaders are showing what’s possible when collaboration meets commitment.

At the @BloombergDotOrg Local Climate Action Summit, mayors, governors and regional leaders are collaborating across levels of government, sharing solutions, and building momentum ahead of #COP30 in Belém. 💪

[Mike Bloomberg @MikeBloomberg]

Cutting methane is one of the fastest ways to slow climate change. Together with @CarbonMapper, @GMethaneHub, & other partners, @BloombergDotOrg is investing $100M to transform how methane super-emitters are found, fixed, & repaired.

[Bloomberg Philanthropies @BloombergDotOrg]

Congratulations to these 12 cities, states and regions for their work in fighting climate change!

Meet the 2025 Bloomberg Philanthropies Local Leaders Climate Awards winners, whose projects represent the most ambitious and impactful climate solutions led by cities, states and regions.

Together with @c40cities, we’re glad to celebrate their standout achievements as part of the @Cop30noBrasil @BloombergDotOrg #COP30 Local Leaders Forum.

Cities are leading the way in showing that it’s possible to clean the air, fast.

Yesterday we heard from the Mayors driving change across @BreatheCities at our #WMS25 session 👇
- Deputy Mayor Mete Coban MBE on how #London’s bold clean air action has lowered NO2 to safe levels 184 years earlier than projected.
- Mayor Trzakowski on how #Warsaw has eliminated 90% of coal ‘smoker’ stoves for domestic heating, driving healthier homes.
- Mayor Galan (Alcaldía Mayor de Bogotá) shared #Bogota’s plans to expand their electric bus fleet, and declare a second clean air zone - action that has seen them recognised as an #EarthshotPrize finalist.
- Mayor Dada Morero reflected on how #Johannesburg has partnered with over 1,000 of the city's young people to drive awareness around tackling dirty air, together.
- Mayor Vassil Terziev highlighted how residents in #Sofia are switching to cleaner heating methods, protecting public health and lowering bills.

I loved moderating this panel and left energised and optimistic after hearing from these Mayors alongside the wonderful @sabrodrigues61, @anthawilliams and @DrMariaNeira.

With deep thanks to @BloombergDotOrg for the vision and support in making #BreatheCities possible, and to @c40cities for our partnership in turning ambition into action across our cities.
