Direct regulation is the government telling people and companies what (not) to do, and how (not) to do it. #climateeconomics
Direct regulation works fine if there are few, similar sources of emissions. It does not work for greenhouse gases. #climateeconomics
Direct regulation was successful, it made the career of current environmental leaders, and so it is still popular. #climateeconomics
Emission reduction costs money as it forces companies and households to use more expensive energy and dearer technology. #climateeconomics
The economy can be fully decarbonized at negligible cost if policy design is smart and abatement is gradual. #climateeconomics
Differences between abatement cost estimates are large, reflecting different assumptions on emissions without policy. #climateeconomics
Fossil fuel combustion is the main source of CO2. Per unit of energy, coal emits most, followed by oil and gas. #climateeconomics
Land use change and cement production are other sources of CO2. Specialized industries emit halocarbons. #climateeconomics
Methane results from paddy rice, livestock, waste, and gas leakage, nitrous oxide from agricultural soils. #climateeconomics
Article 2 of the UN Framework Convention on Climate Change calls for stabilization of the atmospheric concentration of CO2. #climateeconomics
Part of CO2 emissions stay in the atmosphere forever -- or rather, is removed at the rate at which rocks grow. #climateeconomics
Thus, stabilization of the atmospheric concentration of CO2 implies that CO2 emissions have to go to zero. #climateeconomics
People adapt to climate change, reducing the negative impacts and increasing the positive impacts. #climateeconomics
Adaptation reduces the need to mitigate climate change, and mitigation reduces the need to adapt. #climateeconomics
Mitigation requires some international cooperation. Adaptation does not. In fact, most adaptation is local and private. #climateeconomics
