Short introduction on Russia’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 2.2 giga tonnes of CO2 (Gt CO2eq), Russia contributed 4.58% to the global greenhouse gas emissions of 2017 (rank 5 - 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, Russia’s global contribution to greenhouse gas emissions is projected to decrease to approximately 3.92% (2.2 giga tonnes of CO2 equivalent / rank 5 - incl. EU27 on rank 4). The emissions projections for Russia 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, Russia represented 1.92% of the global population. Its Gross Domestic Product (GDP) in 2017 were 3.029% 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 IPPU (78.7% and 10.9%). Amongst the greenhouse gases that are considered in the Kyoto Protocol, the strongest contributor with 76.5% was CO2. This was followed by CH4 emissions, with a significantly lower share of 17.6%. When not considering the sectors and gases independently, but the sector-gas combinations instead, Energy CO2 and Energy CH4 (67.7% and 10.7%) 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.”

In its updated NDC, “the Russian Federation announces a target for limiting greenhouse gas emissions, which provides for a reduction in greenhouse gas emissions by 2030 to 70 percent relative to the 1990 level, taking into account the maximum possible absorptive capacity of forests and other ecosystems and subject to sustainable and balanced social economic development of the Russian Federation.” (NDC, p. 1). Further, “The Russian Federation is concentrating its efforts on reducing anthropogenic greenhouse gas emissions and increasing their absorption, including the implementation of the following measures: increasing energy efficiency in all sectors of the economy, developing the use of non-fuel and renewable energy sources, protecting and improving the quality of natural sinks and storage of greenhouse gases, financial and tax stimulating the reduction of anthropogenic greenhouse gas emissions.” (NDC, p. 5). Even though being contingent on the country’s sustainable and balanced social economic development, we classify Russia’s target as unconditional, as it does not state the need for international support.

With the given emissions for the chosen base year of 1990 (NDC, p. 7; “including emissions and removals from land use, land use change and forestry”, “indicator value: 3.1 billion tons of CO2-eq”), the quantitative information needed to estimate Russia’s target of a 30% reduction in emissions by 2030 compared to 1990 levels, is provided in the NDC. The estimated target emissions of this economy-wide target are 2.2 GgCO2eq AR4 (including LULUCF). The availability of national estimates of emissions mitigation targets and pathways in line with countries’ NDCs is of great importance when, e.g., aggregating to global emissions to then derive, i.a., the resulting end-of-century warming levels. All main IPCC sectors (Energy, IPPU, Agriculture, LULUCF, Waste) are stated to be covered, as well as all seven Kyoto GHGs, leading to a coverage of 100% of Russia’s emissions and removals by its mitigation target.

Regarding Article 6 of the PA (cooperation and markets), “The Russian Federation recognizes the importance of voluntary cooperation in nationally determined contributions to potentially increase the ambition of mitigation and adaptation actions. The possibility of using voluntary cooperation in the implementation of the nationally determined contribution will be considered by the Russian Federation following the adoption by the Conference of the Parties serving as the meeting of the Parties to the Paris Agreement of the rules, conditions and procedures for the mechanisms referred to in Article 6 of the Paris Agreement.” (NDC, p. 13-14).

The NDC-assessment is based on the Russian Federation’s NDC submitted to the UNFCCC in November 2020.

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

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).
