MAASLAND, the Netherlands — A few miles north of Rotterdam, in a region the Dutch call “glass city” for its thousands of greenhouses, gardeners like Frank van Os are part of an unconventional experiment by Royal Dutch Shell to curb carbon emissions.
Mr. van Os produces four million roses each year, flooding the atmosphere inside his vast glass canopy with pure carbon dioxide to bolster his crop. What is unusual is that he now gets the carbon dioxide piped in directly from Pernis, a Shell refinery that is Europe’s largest and typically discharges tons of the gas into the atmosphere every year.
