The United States contributes 16% of the worlds carbon emissions. That amount is large, sure, but eliminating that amount won't stop climate change, it will only stall the problem. In the US, we should move to renewable energy, magnetic energy, or even nuclear as long as there is reliable producer of it. But, We also need to influence the rest of the worlds actions on the crisis. The way I believe we can approach this problem with foreign strategies is not only through trade agreements and diplomacy, but we can also use competition. I want to give an example from history which is the space race. When the space race occurred, many countries including the US competed for the first space ship to land on the moon. These actions improved the countries economy, their work force, and then the outcome rewarded a winner as the most powerful and impressive. While in that time it was not a competition for our survival as a planet, it still is comparable as in the  US can initiate a race to the least carbon emissions. Countries like Russia, China, Saudi Arabia, and more that emit a lot of carbon would compete in this race to the least emissions. Their country industry strategy could be with less oil and more green energy. Every country knows that climate change exists, they just don't have a motivation to stop it. Not only would the race become very entertaining, but it would also be very good for the countries economy. In this race, we would see the world contribute less in carbon emissions and then climate change would slow down at an impressive rate. By the end of the race, each country would have newly designed industries that are environmentally friendly. An example today to just show the power of carbon emissions is the coronavirus. There are images online of the satellite imagery with the air pollution in areas affected by the virus. A before and after picture will show the contrast in air pollution when less people drive versus when more people drive. This race would transform the earth as competition would motivate change as it has in the past. It might not stop climate change, but it will move the entire world closer to a green world.

I think that your idea is good, but a bit too naive.
Indeed, "race to the least emissions" could really give the motivation to countries to reduce their carbon emissions, however the issue is that which country would 'dare' to start this race ? Given the fact that this one country would have to suffer losses without any direct incomes, which seems in our nowadays society of consumption unthinkable.
Also, although the "space race [...] improved the countries economy and work force", I think that the major factor to these benefits we're mostly due to the fact that the Moon was an 'unknown territoty', meanwhile all humans were born on Earth !
Thus, I think that the real requierement to "stop climate change" would first be to change the wole whole mindset of the whole society we live in. Easier said than done !
