Critically Insufficient4°C+ World

NDCs with this rating fall well outside of a country’s “fair share” range and are not at all consistent with holding warming to below 2°C let alone with the Paris Agreement’s stronger 1.5°C limit. If all government NDCs were in this range, warming would exceed 4°C.

Highly insufficient< 4°C World

NDCs with this rating fall outside of a country’s “fair share” range and are not at all consistent with holding warming to below 2°C let alone with the Paris Agreement’s stronger 1.5°C limit. If all government NDCs were in this range, warming would reach between 3°C and 4°C.

Insufficient< 3°C World

NDCs with this rating are in the least stringent part of a country’s “fair share” range and not consistent with holding warming below 2°C let alone with the Paris Agreement’s stronger 1.5°C limit. If all government NDCs were in this range, warming would reach over 2°C and up to 3°C.

2°C Compatible< 2°C World

NDCs with this rating are consistent with the 2009 Copenhagen 2°C goal and therefore fall within a country’s “fair share” range, but are not fully consistent with the Paris Agreement long term temperature goal. If all government NDCs were in this range, warming could be held below, but not well below, 2°C and still be too high to be consistent with the Paris Agreement 1.5°C limit.

1.5°C Paris Agreement Compatible< 1.5°C World

This rating indicates that a government’s NDCs in the most stringent part of its “fair share” range: it is consistent with the Paris Agreement’s 1.5°C limit.

Role model<< 1.5°C World

This rating indicates that a government’s NDC is more ambitious than what is considered a “fair” contribution: it is more than consistent with the Paris Agreement’s 1.5°C limit.

Global Warming Potentials

The CAT uses Global Warming Potential (GWP) values from the IPCC's Fourth Assessment Report (AR4) for all its figures and time series. Assessments completed prior to December 2018 (COP24) used GWP values from the Second Assessment Report (SAR).

Historical emissions

Historical emissions for the year 1994, 2000, 2005 and 2014 are taken from the UNFCCC GHG Inventory database (UNFCCC, n.d.). More detail on the 2014 values are available in UAE’s fourth National Communication (Government of the United Arab Emirates, 2019). The UNFCCC dataset contains two errors, one for the year 1994 where agricultural emissions are 54.5 MtCO2e/a in the UNFCCC database while they are 1.8 MtCO2e/a in the 3rd National Communication (Ministry of Energy, 2012), and one for 2005, where fugitive emissions from the energy sector are double counted, once as methane emissions and once as carbon dioxide emissions (each 21.0 MtCO2e). We corrected the values using the data from the 3rd National Communication.

We linearly interpolate the data between 1994, 2000, 2005 and 2014. For the years before 1994, we linearly expand the trend of the years 1994 – 2005.

Pledges and targets

To quantify the NDC target of 24% of clean energy, we take the following approach explained below. Note that it has not been clear in previous updates whether the NDC refers to total primary energy supply or electricity generation. For this update, we assumed that NDC target is focused on electricity based on a series of supporting documentation (Ministry of Energy, 2015c; The National, 2015; UAE Government, 2018):

24% of electricity generation:

Compare calculation of the Energy Strategy for 2050 below.
For share of electricity generation of different fuels, we assume that the share of coal and oil develop as under the base scenario, and that gas balances the changes in “clean energy”.

Current policy projections

For the current policy projections, we use the following data sources:

CO2 from fuel combustion: “Renewable Energy Prospects – United Arab Emirates” (Masdar Institute/IRENA, 2015)
CO2 process emissions: Own assumption to continue linear trend based on total industrial processes emissions from the years 1994 to 2014 until 2030
Non-CO2 emissions: Global Anthropogenic Non-CO2 Greenhouse Gas Emissions: 1990 - 2030 (US EPA, 2012)

We apply the growth rates of those datasets to our historical data for the year 2014 and sum them.

Two policies are not included in the Masdar/IRENA report: the Energy Strategy for 2050 (WAM, 2017) and the deregulation of prices of gasoline and electricity, which were previously subsidised (IEA, 2015). We consider the Energy Strategy a planned (rather than implemented) policy, and thus do not include the targets in the current policy projections.

The deregulation of fossil fuel prices is included in the current policy projections. To estimate the impact of the fuel subsidies-phase out, we take into account an IISD report that calculates the impacts of subsidy phase-out in the UAE and other countries. This report states that national energy related emissions in the UAE would decrease by 14% in 2020 and 12% in 2025 if all subsidies were taken away (Merrill et al., 2015). It is unclear how the reductions relate to the different energy carriers, we thus present a range:

Lower end: We subtract this amount from our own estimate of energy-related CO2 emissions for 2020 and 2025, and assume for 2030 that there is a linear trend in the reduction rate as given by Merrill et al. (2015).
Upper end: We apply the percentage given only to emissions related to oil consumption.

We assume that there is no impact on other gases.

To estimate the potential impact of the Energy Strategy (considered a planned policy), we take the following approach:

Determine shares of energy carriers in electricity generation up to 2030: Linear interpolation of shares for different energy carriers between last available year in IEA statistics (IEA, 2016) and 2050 targets.
Apply emission factors of electricity generation: Take last available year from IEA statistics and assume 1% autonomous improvement per year.
Determine total electricity generation up to 2030: Use values from Masdar/IRENA report (Masdar Institute/IRENA, 2015). To reflect energy efficiency target we assume that efficiency improvements are equal for all energy carriers, meaning that electricity is reduced at the same rate as others. This would not work for deep decarbonisation pathways, but the targets do not reflect that,
- Efficiency is measured in total final energy consumption per GDP, and
- Electricity generation equals consumption.
