Air conditioning systems are significant contributors to global warming, and replacing them with more efficient systems could have a big impact, according to a new UN report.
An estimated 3.6 billion cooling appliances are in use globally today, and that number is growing by up to 10 devices every second, the report says. To make matters worse, most air conditioning units use hydrofluorocarbons (HFCs), which are potent greenhouse gases.
Without policy intervention, emissions from air conditioning and refrigeration are projected to rise 90% above 2017 levels by 2050. Among the possible solutions are measures to encourage implementation of cooling retrofits and passive technologies.
Rebates and incentives to promote cooling efficiency in the built environment could also have a significant impact as would financial support to develop new cooling technologies.

EPA Says Additional Lead Paint Cleaning Rules Not Necessary
The EPA has concluded that current Lead: Renovation, Repair, and Painting Program (LRRP) cleaning requirements and lead-safe work regulations are sufficient to protect the public from lead dust hazards. “Our members have been instrumental in contacting legislators to detail the detrimental impact of the current LRRP," says Richard Walker, American Architectural Manufacturers Association’s president and CEO. “This collective industry voice has prompted the EPA to make the responsible decision to refrain from adding further, unnecessary costs to homeowners under the current economic climate."http://www.aamanet.org/news/1/10/0/all/603/aama-commends-its-members-congress-for-vacating-lrrp-clearance-rule
