The United Sates’ NDC proposes an economy-wide target to reduce GHG emissions by 50-52% below 2005 levels (i.e. 6,635 MtCO2e) by 2030. In 2025 emissions are expected to reach between 26-28% below 2005.
To United States proposes a shift to low carbon economy and scale up offshore renewable energy. In the electricity sector, United States aims to shift towards carbon-free electricity by 2035, increase energy efficiency, scale up distinct energy sources as hydrogen and invest in carbon capture. In the transport sector the kernel is to switch petrol fuelled vehicles to zero emission ones. Also, raise efficiency standards and investments in both low carbon fuels and alternative transport modals (e.g. rail and biking). In the building sector the focuses are on the enhancement of energy efficiency of electric heating and cooking devices, for instance investing in heat pumps and induction stoves. In the industry sector the government plans to shift fuel burning processes to very low- or zero-carbon processes and to invest in carbon capture. Agriculture and land use are also target by reforestation plans, rotational grazing and forest protection to avoid wildfires.
According to Climate Action Tracker, this target would translate into 1.5-2.5 GtCO2e/yr lower emissions in 2030 below the current policies trajectory. CAT points out that this target includes LULUCF and excluding it would translate to a 43-50% reduction below 2005 levels (Climate Action Tracker, 2021).
The methodology used followed the IPCC 2006 guidelines and considered the GWP from the AR5.
