Measuring the Impact of Multiple Air Pollution Agreements on Global CO2Emissions
研究了1970-2008年150个国家签署多项空气污染协议对二氧化碳排放的影响，发现每多批准一项协议会显著降低排放量，即使协议并非针对二氧化碳。
This paper studies the effect on CO<sub>2</sub> emissions of the various agreements that follow the Long-Range Transboundary Air Pollution Convention and are related to acid rain problems. The analysis is based on a panel dataset of 150 countries over the period 1970–2008 and deals with the problems linked to the analysis of multiple agreements (e.g., time and membership overlap). We show that ratifying an additional treaty has a significant and negative impact on the level of CO<sub>2</sub> emissions, even if it is not targeted toward CO<sub>2</sub>. <i></i>
