We're making our GreenSpec list and checking it twice. Crossing ozone depletion off of it feels mighty nice! With the holiday season upon us (yet no snow on the ground here in Vermont since the freak October storm that knocked out power across the... Next up: global warming The ozone hole problem is by no means a done deal. For one, it'll take a while for the ozone hole to start to repair because many ozone-depleting substances stay in the atmosphere for a very long time. Also, a lot of the standard replacements, including R-134a and R-410a refrigerants and many common blowing agents, don't deplete the ozone but are potent contributors to global climate change . The good news is that we're starting to act on that problem too: there are efforts to phase down use of HFCs and replace them with substances that don't create an ozone problem or a climate problem . The kind of substantive but phased approach we've taken with this problem makes it clear to manufacturers what's required and enforces an even playing field, helping us transition smoothly to preferable alternatives. A season of hope Yes, complications abound, and there are always more caveats, but it gives me good cheer to revisit proof that we actually can cooperate internationally to address a major environmental issue at it's source– with ozone we're quietly proving it right now.
