I see countries are having another meeting about methane to make pledges few will meet.  It's a political game, to me, they want to be seen as doing something while doing very little beyond some PR.  The real problems we have because folks play games with them instead of laying out what is neccessary to solve them blaming the other party for eventual inaction.

WASHINGTON (AP) — In what officials call a key step to combat climate change, the Environmental Protection Agency is sharply limiting domestic production and use of hydrofluorocarbons, highly potent greenhouse gases commonly used in refrigerators and air conditioners.

The new rule, which follows through on a law Congress passed last year, is intended to decrease U.S. production and use of HFCs by 85% over the next 15 years, part of a global phaseout designed to slow global warming.


The rule is expected to reduce harmful emissions by the equivalent of 4.5 billion metric tons of carbon dioxide by 2050, McCarthy said, a total similar to three years of emissions from the U.S. power sector.

EPA Administrator Michael Regan said the phasedown is backed by a coalition of industry groups that see it as an opportunity to “supercharge” American leadership on domestic manufacturing and production of alternative refrigerants. The industry has long been shifting to the use of alternative refrigerants and pushed for a federal standard to avoid a patchwork of state laws and regulations.


The administration said it also is taking other steps to ensure reductions in HFCs, including creation of an interagency task force to prevent illegal trade, production, use or sale of the climate-damaging gases. The task force will be led by the Department of Homeland Security, and EPA’s offices of Air and Radiation and Enforcement and Compliance Assurance.

White roofs is a good idea generally, but it's not going to replace air conditioners obviously.  And 90% is obviously pretty good if it's cheaper or longer lasting.

The building next to us has a white roof, it's dirty, but whitish.

RV roofs are typically white for this reason.

Some people even paint the center roof panels of an all-aluminum Airstream white, the white paint reflects away more solar radiation than does the bare aluminum.

School bus roofs are white around here.  I know LA experimented with painting a piece of pavement white, I viewed it as a gimmick, and it was.

I could see painting parking lots white, they really retain a lot of heat.  

I also like having a lot of trees in an urban heat island, it helps quite a bit, shade and respiration/evaporation/transpiration.

School bus roofs here are yellow, but it would make sense to paint them white.  It must cost more...

I would like more trees planted along Interstates where there is room far enough from the traffic.  I noticed places in GA where they have removed the trees growing in the medians for some reason, it looks expensive, maybe to be replaced with better trees?

But trees can't be allowed to die and rot at the end of their lives if you want to capture the CO2.  My guess is trees are a lot better at carbon capture than our plants.
