The #SummerSolstice marks the longest day of the year and official start of summer: long days and ever warmer weather—a time of year many look forward to. But increasingly, the summer weather has started too early, has become too long hot and too hot!

How to best keep cool and beat the heat can often be a real struggle. Here are some tips to help you keep your cool, while other are losing theirs.

🌀 Let cool air in and encourage air flow: Open windows on opposite sides of the house to encourage air flow to release trapped warm air and allowing in cooler air. Do this overnight or in the early morning when it is cool outside.

🪟 Keep warmer air out during the day: In the heat of the day keep your windows shut and blinds or curtains closed in the sunniest parts of the home.

🪭 Use a fan to enhance the breeze and keep the air moving. If its still cooler outside, placing a fan in front of an open window draws the cooler air into the room.

🍳 Limit hot activities: Avoid cooking, using the oven other appliances, such as washing machines and dishwashers that emit heat. Stick to eating cold foods such as salads.

🧊 Cool yourself down: Cool showers are an effective way to bring down your body temperature as will placing an ice pack or cold-water bottle.

🍙 Find an alternative space: Air-conditioned public building such as libraries, leisure centres and shopping centres can also provide relief if your home is too hot. More and more, local authorities are creating so-called "cool spaces" to help people beat the heat.

For the love of food🍓🥗🥐 #SustainableGastronomyDay celebrates the art of food but also how we source and store what we eat.

Up to a third of food is lost or wasted globally. A major cause of this? Lack of reliable cooling, especially for fresh foods.

Through the Kigali Amendment, celebrating its 10th anniversary, the MontrealProtocol supports sustainable cooling solutions—helping strengthen cold chains, reduce food loss, protecting both people and the planet.

As the Kigali Amendment marks its 10th anniversary this year, HE Abdourahmane Diouf reminded us in his address at a high-level event during #UNEA7 of our collective responsibility to prioritise its full ratification and effective implementation.

Because as temperature records keep on getting broken, the collective benefits of the Amendment are clear:

🔹 Potential to avoid up to a combined 1°C of global warming by 2100 through the phase down of HFCs and energy efficiencies in cooling
🔹 Driving sustainability in the sector
🔹 Unlocking investment, innovation, and green jobs

Without the Protocol, “models show that there would have been catastrophic ozone depletion, exposing all living things on Earth to huge and ever increasing dangerous amounts of UV radiation,” says @SEHay_Smith, communications and information officer at the United Nations Environmental Programme’s @UNEPozone

At the 79th World Health Assembly #WHA79, Member States adopted Resolution WHA79.13 on "Radiation and Health" requesting a global mapping of actors, their mandates and gaps in relation to radiation and health—to strengthen and advance the public health agenda on ultraviolet (UV) radiation, protection, preparedness and response.

The resolution is an acknowledgement of the significant impact on health of #UV radiation—a major environmental risk factor for cancer.

The Montreal Protocol plays a vital role in this agenda by not only protecting the ozone layer—the Earth’s natural shield against harmful UV radiation—but also by monitoring UV radiation. The Protocol's Environmental Effects Assessment Panel regularly assesses and reports on the effects on human health from UV exposure due to stratospheric ozone depletion.

The forty-eighth meeting of the Open‑ended Working Group (OEWG48) is fast approaching, bringing parties together to advance the vital work of the Montreal Protocol and its Kigali Amendment.

As we prepare for this important session, we look forward to constructive discussions, continued collaboration, and practical solutions to accelerate action on ozone layer and environmental protection.

#OEWG48 will be another key opportunity to build on past progress, strengthen cooperation, and help pave the way for successful outcomes at the next Meeting of the Parties.

#MontrealProtocol continuing to deliver impactful results for the ozone layer, for the environment, and for future generations 🌿

Ambition alone is not enough. To deliver safer, healthier and more prosperous societies, implementation and enforcement must keep pace with commitment.

From record temperatures in Europe to compounding climate impacts across Africa, Asia, and small island states, the urgency is clear: climate action must deliver results.

The Montreal Protocol and its Kigali Amendment offer one of the fastest ways. But progress depends on something often overlooked: enforcement.

Customs authorities are on the frontline — preventing illegal trade, protecting environmental gains, and safeguarding global supply chains.

On World Food Safety Day, the theme focused on “From burden to solutions – safe food everywhere” highlighting the urgent need to reduce food loss and ensure safe consumption.

A key part of the solution is access to sustainable cold chains.

The Montreal Protocol, through its Kigali Amendment, is driving the transition to energy-efficient, climate-friendly cooling technologies helping to:

🥕 Reduce food loss and waste
🛟 Improving food safety
👨‍🌾 Supporting farmers and supply chains
🌿 Protecting the environment

With nearly one-third of global food production lost or wasted—often due to limited refrigeration—expanding sustainable cold chains is essential to ensuring food reaches people safe and in good condition.

On #WorldEnvironmentDay, we often focus on forests, oceans, and wildlife. But one of the most powerful levers for environmental protection lies in the hands of refrigeration and air-conditioning (RAC) technicians.

Through proper installation, maintenance, and smart servicing practices, technicians:

✅ Prevent harmful refrigerant emissions
✅Improve energy efficiency
✅Support the transition to climate-friendly cooling technologies

As an implementing partner of the Montreal Protocol, OzonAction works to strengthen technician capacity worldwide—helping countries protect the ozone layer while advancing climate action.

This World Environment Day, let’s recognise the people behind sustainable cooling!

⁉️ Did you know the Montreal Protocol changed weather patterns ⁉️

A depleted ozone layer enabled more ultraviolet radiation to penetrate to Earth's surface, the ozone hole forming over Antarctica each year created many wide-ranging climate impacts on the Southern Hemisphere.

By the 1980s, scientists noted that jet streams were changing. As a result Australia got drier, and the rain increased in parts of Uruguay, Brazil, Paraguay and Argentina.

The changing wind patterns that caused these effects paused around the year 2000, approximately when the Montreal Protocol began to take effect. In 2020, researchers from @NOAA Chemical Sciences Laboratory documented that declining atmospheric concentrations of ozone-depleting chemicals were responsible.

Hurray for the weekend and hurray for the #MontrealProtocol 🎉

“Because I know Paris’s efforts at planting and cooling down certain areas, I’m adapting my tours. The worst is the stretch between the Louvre and the Opéra Garnier. In the 19th century, Charles Garnier said he wanted no trees obscuring the views towards the Louvre. He didn’t know what the future held in store in terms of temperature.”

As temperatures in Europe—still in the late stages of spring—reach summer heatwave levels, efforts to adapt cities, public spaces, and private homes into cool havens must not only accelerate, but also remain sustainable.
