US and China energy and climate policy and the G20

Climate and energy policy is once more near the top of the US government’s policy agenda, and occupies a prominent position in China’s development planning and policy. Both countries strive for global leadership on clean energy technologies, and both are preparing national pledges to reduce or constrain their carbon emissions for the period after 2020. The active pursuit of this policy agenda has implications for the strategic relationship of the world’s superpowers, and for the G20 agenda.
