Air-Conditioning Discovery Eliminates Harmful Gases Scientists just invented an air conditioner that avoids harmful refrigerant gases. Refrigerant gases are some of the strongest emitters causing climate change.

The use of environmentally damaging gases in air conditioners and refrigerators could become redundant if a new kind of heat pump lives up to its promise. A prototype, described in a study published last week in Science, uses electric fields and a special ceramic instead of alternately vaporizing a refrigerant fluid and condensing it with a compressor to warm or cool air.

Three positive climate developments - The climate trajectory, while still poor, has improved since countries signed the Paris Agreement in 2015 and committed to limiting the global temperature rise to "well below" two degrees Celsius above pre-industrial levels, preferably a safer 1.5C.

And the uptake of renewable energy is providing a rare glimmer of hope.

When the Paris Agreement was adopted, the global reliance on fossil fuels—oil, gas and coal—placed the world on a path towards a 3.5C rise in temperature by 2100 compared to the pre-industrial era, the International Energy Agency (IEA) said at the time.

  • Eight years on, country commitments to reduce their carbon footprints have pulled that down slightly, putting the world on a path for a still-disastrous 2.5C to 2.9C by the end of the century, according to the UN's Environment Programme this month.

  • The climate experts of the UN Intergovernmental Panel on Climate Change (IPCC) have projected that to meet the Paris goals, emissions need to peak by 2025. To limit temperature rise to 1.5C emissions need to be slashed almost in half by 2030. Recent estimates by the Climate Analytics institute find global emissions could peak by 2024 or even as early as this year.

  • Three technologies—solar, wind and electric vehicles—are largely behind the improved global warming estimates since 2015.

This week was key for carbon dioxide removal (CDR) around the world, as the EU Parliament officially approved the Carbon Removal Certification Framework (CRCF) and the Net Zero Industry Act (NZIA).

The amendments adopted by the Eur opean Parliament on the Carbon Removal Certification Framework from the text proposed by the Commission, aim to ensure a more robust framework. Overall, they are a step forward towards recognizing carbon removals as a necessary part of the net zero mix and integrating them into the EU climate policy landscape.

The Parliament introduced four distinct types of certified units – carbon removal, carbon storage in products, carbon farming sequestration, and carbon farming emissions reduction. Only activities that store atmospheric or biogenic carbon for ‘several centuries’ are able to qualify as carbon removals. The amendments confirm these four different activities will generate distinct certificates.
