³Mexico was the second country to have a national climate change law, after the UK. The U.S. mid-century low greenhouse gas emissions strategy lays out multiple pathways for achieving ambitious reductions of domestic net greenhouse gas emissions by 2050, consistent with holding global average temperature increases to well below 2 °C. The U.S. strategy envisions actions across three categories: (1) the transformation to a low carbon energy system, including a near-complete decarbonization of the electricity grid and deep emissions reductions across the transportation, buildings and industrial sectors; (2) storing carbon and reducing emissions through U.S. lands and agriculture; and (3) reducing nonCO₂ emissions such as methane, nitrous oxide and fluorinated gases, despite large increases in key drivers of these emissions (e.g. agricultural production). To achieve a low GHG pathway, the U.S. strategy envisions an aggressive and cost-effective suite of public policies that include market incentives to reduce emissions and public support for research, development, demonstration & deployment (RDD&D).
