But penalties for factories, power plants and cars to emit carbon dioxide into the atmosphere are low or non-existent. And isolating carbon dioxide is complex because the gas makes up just 0.04% of the air. "We're in trouble," said Janos Pasztor, head of the new Carnegie Climate Geoengineering Governance Project. By contrast, he said "carbon dioxide removal is challenging technologically, but deserves investment and trial." Another option is to build power plants that burn wood and bury the carbon dioxide released.
