Short introduction on Egypt’s emissions

Although CO2 is the driving force behind the temperature changes, other gases such as methane (CH4) also contribute their share to global warming, for example through the exploitation of gas fields, and emissions by livestock. While methane is emitted much less than CO2 on a global scale, it is a much stronger greenhouse gas (GHG). Scientists estimated the relative strength of the important Kyoto greenhouse gases so that we can convert all emissions to an equivalent of CO2 emissions. For example, the emission of one ton of methane has approximately the warming effect of 25 tons of CO2. The factor of 25 reflects the climate forcing on a 100-year time horizon, following the Global Warming Potential presented in the IPCC Fourth Assessment Report (AR4).

With greenhouse gas emissions of approximately the equivalent of 309.7 mega tonnes of CO2 (Mt CO2eq), Egypt contributed 0.65% to the global greenhouse gas emissions of 2017 (rank 32 - incl. EU27 on rank 3). All emissions estimates exclude emissions and absorption from land, which result from activities such as cutting down or planting of forests (Land Use, Land-Use Change and Forestry: LULUCF). Emissions from bunker fuels (international aviation and shipping) were also excluded, as they are not accounted for in national totals.

For 2030, Egypt’s global contribution to greenhouse gas emissions is projected to increase to approximately 0.87% (490.3 mega tonnes of CO2 equivalent / rank 22 - incl. EU27 on rank 4). The emissions projections for Egypt were derived by downscaling the Shared Socio-Economic Pathways’ (SSPs) “Middle-of-the-Road” baseline marker scenario SSP2. These pathways describe certain narratives of socio-economic developments and were, i.a., used to derive greenhouse gas emissions scenarios that correspond to these developments. SSP2 is a narrative with little shifts in socio-economic patterns compared to historical ones, and is connected to medium socio-economic challenges for both climate mitigation and adaptation. While different models were used for each storyline, per SSP (SSPs1-5) one model was chosen as representative “marker scenario”. As the emissions projections are not readily available on country-level, but national estimates are important, the pathways were downscaled in the aftermath. In 2017, Egypt represented 1.27% of the global population. Its Gross Domestic Product (GDP) in 2017 were 0.89% of the global GDP.

Looking at the highest contributing emissions sectors and gases separately, we find that in 2017 the highest contributing emissions sectors were Energy and Agriculture (63.9% and 13.4%). Amongst the greenhouse gases that are considered in the Kyoto Protocol, the strongest contributor with 71.5% was CO2. This was followed by CH4 emissions, with a significantly lower share of 18.3%. When not considering the sectors and gases independently, but the sector-gas combinations instead, Energy CO2 and IPPU CO2 (60.7% and 9.5%) represented the largest emissions in 2017.

Greenhouse gas mitigation and Nationally Determined Contribution (NDC)

In 2015, the majority of countries agreed to the Paris Agreement (PA), with the goal of “Holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change” (Article 2.1.a). Countries stated their pledges and targets towards achieving the PA’s goals in their Nationally Determined Contributions (NDCs). With Article 4.4 of the Paris Agreement, Parties decided that “Developed country Parties should continue taking the lead by undertaking economy-wide absolute emission reduction targets. Developing country Parties should continue enhancing their mitigation efforts, and are encouraged to move over time towards economy-wide emission reduction or limitation targets in the light of different national circumstances.”

Egypt’s NDC does not contain a clear quantifiable GHG mitigation target. It does contain mitigation policies, however, with “The key for Egypt to mitigate GHGs emissions is to provide appropriate foundations for the development of low carbon energy systems.”(NDC, p. 10). Here, the general “Pathways to achieving high CO2 mitigation levels” are stated as well as the “five main pillars” the “Policies targeting development that is more sustainable rely upon”. Based on the following declarations, we assess Egypt’s NDC not to be unconditional: “Thus, Article 4 of the UNFCCC, which states that developed parties shall provide support to developing countries in applying their liabilities, should be enacted. Hence, Egyptian national efforts alone will not be able to fulfill the State aspirations in contributing to the international climate change abatement efforts. Depending only on local financial resources, along with the large development aspirations of Egypt, will limit this contribution.” (NDC, p. 13).

In its NDC, the country lists “Greenhouse Gas Mitigation Measures in Different Energy Sub-Sectors” (NDC, p. 11), as well as “GHGs Emissions Reduction Actions in Non-Energy Sectors” (NDC, p. 12). Furthermore, the country indicates that the “Pathways to achieving high CO2 mitigation levels comprise the following: […] Comprehensive mitigation efforts covering all major sources of emissions” (NDC, p. 10). Based on the given information, we assess measures to cover all main IPCC sectors (Energy, IPPU, Agriculture, LULUCF, and Waste). The covered Kyoto GHGs are not clearly defined in the NDC. CO2 is mentioned as “Pathways to achieving high CO2 mitigation levels comprise the following” (NDC, p. 10), and regarding the country’s absorptive capacity (“Additional mitigation measures include the increase of the country’s CO2 absorptive capacity through plantation, maintaining suitable types of trees along road sides, the middle-island of inter-city and urban roads, and on irrigation and drainage canal banks. In addition, wood forests should use treated wastewater for irrigation.”, NDC, p. 11). Due to missing clarity, we assume CO2, CH4, and N2O to be addressed by Egypt’s NDC. This sectoral and gas coverage would result in approx. 98.9% of national 2017’ emissions being included in the NDC.

As for new market mechanisms, Egypt announces that “A national market for carbon trading may be established. This national market may further be developed into a regional market, which can attracting foreign direct investment in national carbon credit transactions, especially in the Arab and African region.” (NDC, p. 12).

As we did not quantify mitigation contributions by Egypt, we assume the country’s emissions to follow projected baseline emissions. This is of special need when aggregating country-level data to regional or global values, to then, e.g., derive estimates of the end-of-century warming levels in line with mitigation pledges.

The NDC-assessment is based on Egypt’s NDC submitted to the UNFCCC in June 2017.

The Figure below provides additional information, regarding both the baseline emissions used in our assessment and the quantified mitigated pathways for Egypt.

Baseline emissions and mitigated emissions pathways based on the country’s Nationally Determined Contribution. In terms of national emissions, we look at the SSP2 baseline marker scenario, and the emissions of all IPCC sectors. Contributions from LULUCF are excluded (exclLU), and the emissions are based on GWPs from AR4. The left panel (a) shows the baseline emissions, indicating the contributions of the Kyoto Greenhouse Gases CO2, CH4, N2O, and the basket of F-gases to the national emissions. If we could extract baseline data exclLU from the NDC, you can see their values as black squares (converted from GWP SAR to AR4 if needed). In the right panel (b), the quantified mitigated emissions pathways are shown, based on information from the country’s NDC and also on non-NDC emissions baselines, per target conditionality and range (marked un-/conditional best/worst). Even though not all countries have targets with different conditionalities or ranges, we need assumptions for all four cases to build one global pathway per conditionality plus range combination and to derive corresponding temperature estimates. Therefore, we indicate these four pathways here. Per combination, we performed several quantifications with differing assumptions and show the median and the minimal and maximal pathways here. Additionally, if we could quantify the targets based on data extracted purely from the NDC - or if the targets were directly given in absolute emissions, these targets are shown as squares (in the GWP originally given in the NDC).
