UN Warns Nations Must Dump Inefficient Air Conditioners in Order to Act on Climate

As Electrek reported, a new UN report has shown that if households around the world stop using poorly made air conditioning units in addition to ensuring they’re manufactured twice as efficiently as they are now, this would make a significant contribution to keeping to the Paris Agreement’s targets of a global temperature rise of 1.5C by 2050.

People need to be protected from extreme heat, which will in part require ensuring everyone has access to air conditioning–something the City of New York is working to implement. We will also need better policy and city and building design to keep help keep cities and people cooler.

Especially as nations are working to recover and rebuild from the coronavirus pandemic, it’s an opportune time to address air conditioning and cooling/heating efficiency. As Inger Andersen, the Executive-Director of the United Nations Environment Programme said, nations “have an opportunity to use their resources wisely to reduce climate change, protect nature and reduce risks of further pandemics. Efficient, climate-friendly cooling can help to achieve all of these goals.

Why This Matters: As our planet warms and extreme heatwaves become longer and more deadly, more people will require air conditioning to stay cool and safe. In fact, it’s estimated that around two-thirds of the world’s households could have an air conditioner by 2050, and the demand for energy to cool buildings will triple. We must be proactive rather than reactive in how we will cool buildings without generating staggering emissions.

The Details: The Cooling Emissions and Policy Synthesis Report, from the UNEP and the International Energy Agency (IEA), shows that up to 460 billion tons of greenhouse gas emissions – roughly the amount produced over an eight-year period – could be cut over the next four decades by making air conditioners twice as efficient as they are now: by 2050, it would be possible to save the amount of electricity produced by all the coal-fired power stations in China and India in 2018, saving up to $2.9 trillion.

FYI: Unrelated to cooling efficiency, but very pertinent to the COVID-19 pandemic, a new study conducted by the University of Maryland shows just how quickly the virus can circulate around the home. Researcher Dr. David Krause said central air conditioning, in particular, can disperse the virus from room-to-room.

“If you have someone that you’re trying to isolate and who is either sick or is positive with COVID — we want to make sure their room is isolated from the home central air conditioning system,” Krause said. “That can be achieved using either a wall unit or a window unit.”

Click to Climate: EPA’s Data Tracker is Back

After a four-year hiatus under the Trump administration, the Environmental Protection Agency’s Climate Change Indicators website is back in action. The public portal includes data on 54 indicators including sea-level rise, Great Lakes ice cover, heat waves, river flooding, and residential energy use.

Why This Matters: People are experiencing the impacts of climate change in their everyday lives, from hotter temperatures to more intense wildfire seasons.

Explain It To Me: What is a Metric Ton of Carbon?

When reading about climate change, you’ll often come across the unit of measurement called a “metric ton of CO2.” That sounds like a lot, but the unit is a bit abstract for most of us when our reference point for a ton is a VW Beetle, the Liberty Bell, or even a baby humpback whale […]

Oh No! Climate Change Threatens Global Tea Production

According to a new report from Christian Aid, Kenya, which produces half of all black tea consumed by the UK, may lose a quarter of its growing capacity by 2050, and the tea that makes it into drinkers’ cups may taste a lot different than before.  The decline of tea farming has implications for economies worldwide, including Kenya, India, China, and Sri Lanka.

Why This Matters: Tea is the most popular drink other than water globally and the tea industry employs more than 3 million people in Africa alone.
