Japan is the world's fifth largest carbon emitter. The developed country is likely to agree to a comprehensive climate change agreement, but that pact would have limited effect on future global emissions as Japan is not projected to be a key emitter in years to come as China, India, and Brazil develop.
As the president of the United States crafting national and international strategies for dealing with climate change, you have made a series of decisions. Let's analyze the implications of each of your choices.
First, you decided to simply announce a new set of carbon emissions goals instead of advocating for concrete policy change. This decision will not help the US combat climate change as the goals you have set are unenforceable. Lobbyists, NGOs, scientists, and the international community are sick of toothless political statements and view your attempt at domestic leadership on climate change as a failure.
Second, you chose to pursue a bilateral agreement with Japan. The Japanese government agreed to binding long-term standards for emissions and technological exchange with major renewable energy firms in the US. This agreement will further help the fight on climate change as it will pave the way for similar agreements with other countries later on. However, you must keep in mind that developing countries such as China, India, and Brazil will control the future of climate change.
Overall, you have done a subpar job. You did not make any meaningful progress with regards to domestic energy policy. That being said, you crafted a solid agreement with Japan to ramp up its climate change response. Unfortunately, the impact of your bilateral agreement will be limited. As the threat of climate change looms large, the international community must band together and act before it is too late.
