Remove Emissions

If we do not manage to reduce our emissions rapidly, more and more attention is being given to removing greenhouse gases in the atmosphere by other strategies. A number of strategies for removing greebouse gases are available and we have listed some on this page. Paul Hawken recently published Drawdown which lists approximately 80 strategies, and Carbon Brief has listed 10 frequently proposed technologies. However, some strategies reduce warming without reducing the amount of greenhouse gases in the atmosphere and that does nothing to reduce ocean acidification which many see as a greater threat to our wellbeing.

Drawdown

Drawdown maps, measures, models, and describes the 100 most substantive solutions to global warming. For each solution, it describes its history, the carbon impact it provides, the relative cost and savings, the path to adoption, and how it works. The goal of the research that informs Drawdown is to determine if we can reverse the buildup of atmospheric carbon within thirty years. All solutions modeled are already in place, well understood, analyzed based on peer-reviewed science, and are expanding around the world.

They have ranked the top 80 solutions and the total emissions are approximately 1,050 Gigatons of carbon dioxide equivalents. The top solution is managing refrigerants (air-conditioning and refrigerators). Ranked next are onshore wind turbines (off-shore turbines are ranked lower although they also drawdown emissions.)

For example, the following electricity generation options would drawdown a total of 246 Gigatons.

The following slideshow describes some of the strategies that Drawdown proposes.

Ocean acidification

Strategies which reduce warming without reducing the amount of greenhouse gases in the atmosphere do nothing to reduce ocean acidification which many see as a greater threat to our wellbeing.
