تغییرات اقلیمی و اقتصاد در باخا کالیفرنیا: ارزیابی اثرات اقتصاد کلان برنامه اقدام آب و هوایی کشور

Despite its developing country status, Mexico ranks 10th worldwide in total greenhouse gas (GHG) emissions. However, Mexico's vulnerability to climate change impacts is a major motivating factor behind its announced intended contributions at COP21 to cut its baseline emissions by at least 25% in 2030. We analyze the macroeconomic impacts of the Climate Action Plan (CAP) process undertaken in the Mexican border state of Baja California (BC). We adapt a state-of-the-art regional macroeconometric model to analyze the BC economy-wide impacts of 22 GHG mitigation policy options recommended in the Baja California CAP. The combined effects include an average annual increase of 1680 new jobs (or about 0.11% of the average annual employment in the baseline economic forecast) and a Gross State Product (GSP) increase of $9.85 billion pesos in NPV over the 2015–2030 planning horizon. Although the main objective of GHG mitigation is to reduce atmospheric concentrations, and hence future potential damages of these pollutants, the stimulus to the BC economy from the implementation of its CAP represents a valuable co-benefit. Moreover, it is a tangible one that will take place in the near-term, in contrast to the more long-term and more uncertain benefits associated with reducing climate change damages.
