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. For sectors, the rating indicates that the target is consistent with warming of greater than 4°C if all other sectors were to follow the same approach.

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. For sectors, the rating indicates that the target is consistent with warming between 3°C and 4°C if all other sectors were to follow the same approach.

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. For sectors, the rating indicates that the target is consistent with warming over 2°C and up to 3°C if all other sectors were to follow the same approach.

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. For sectors, the rating indicates that the target is consistent with holding warming below, but not well below, 2°C if all other sectors were to follow the same approach.

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. For sectors, the rating indicates that the target 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. No “role model” rating has been developed for the sectors.

Economy-wide

Between 1990 and 2014, South Korea's emissions more than doubled. Emissions steeply increased in the early 1990s, with growth then continuing at a slower pace, and the CAT projects that GHG emissions growth will continue to slow. Actual emissions levels in the period 2010–2014 were above the BAU projections from the Third National Communication.

South Korea is one of the countries with the fastest growing emissions in the OECD. The high export rates from South Korea’s manufacturing industry play a critical role in South Korea’s increasing emission levels (Kim et al., 2015). In other developed Asia-Pacific Economic Cooperation (APEC) economies such as the US, Australia or Canada, energy consumption per capita is declining as economies shift towards the service sector and improve energy efficiency. However, South Korea is an exception: energy per capita continues to rise as industrial energy use increases and population declines (APERC, 2016).

Currently implemented policies are estimated to lead to an emissions level of 737–753 MtCO2e/year in 2030 (151–157% above 1990 levels), excluding emissions from land use, land use change and forestry (LULUCF). To reach its 2030 NDC target, South Korea will have to strengthen its climate policies.

South Korea has implemented its Green Growth Strategy, a comprehensive policy package targeting all policy areas including climate change. One of its key policies is the cap and trade scheme introduced in January 2015.

South Korea introduced the GHG and Energy Target Management System (TMS) in 2012, which was a precursor to the Emissions Trading System (ETS) and covered 60% of total emissions. The TMS still covers emitters consuming significant amounts of energy that are not covered by the ETS. As a result of TMS operations, 65 companies collectively reduced their emissions by 0.74 MtCO2e/year in 2015 compared to business-as-usual (Republic of Korea, 2017b),Introduced in 2015, the ETS manages 69% of the national GHG emissions and covers more than 600 companies from 23 sub-sectors (Republic of Korea, 2017b) from steel, cement, petrochemicals, refinery, power, buildings, waste and aviation sectors; this includes all installations in the industrial and power sectors with annual emissions higher than 25 ktCO2e. The ETS system includes both direct and indirect emissions (emissions from electricity use).

In Phase I (2015–2017) of the ETS, all allowances were freely allocated. Auctioning will only take place for 3% of allowances in Phase II (2018–2020) and for 10% of allowances in Phase III (2021–2025) (IETA, 2015). Energy-intensive and trade-exposed sectors will receive free allowances for all their emissions in all three phases. In Phase I, the plan was to decrease the absolute emissions cap from 573 MtCO2e/year in 2015, to 562 MtCO2e/year in 2016 and 551 MtCO2e/year in 2017 (Carbon Market Watch, 2015). In addition to the overall cap, the ETS also sets sectoral caps that reflect sectoral-based emissions reduction targets (ICAP, 2016). The sectors were selected based on the size of their contribution to the country’s overall emissions. They were expected to play an important role in meeting South Korea’s former target of reducing emissions to 30% below the baseline by 2020, with sector-wide reductions ranging from 17.5% for waste to 34.3% for transport. The caps for Phase II and Phase III have not been announced.

In 2016, responsibility for the ETS shifted from the Ministry of Environment to the Ministry of Strategy and Finance (Carbon pulse, 2016) and the ETS was adjusted to ease the pressure on market participants (ICAP, 2017). As part of those adjustment measures, an additional 17 MtCO2e of allowances were added to the annual cap in 2016 (Republic of Korea, 2017a). In addition, the share of allowances that companies are allowed to borrow for compliance was doubled from 10% to 20%.

Energy supply

South Korea’s power demand increased by 162% over the period 1990–2013 and is dominated by coal-fired (43% in 2015) and nuclear generation (30% in 2015) (IEA, 2016). South Korea introduced a Renewable Portfolio Standard (RPS) in 2012, replacing a previous feed-in tariff scheme. The new standard obliges suppliers to meet annual generation targets from renewable and new energy, starting at 2% and increasing to 10% in 2024 (IEEJ, 2014). In this target, coal-fired Integrated Gasification Combined Cycle (IGCC) plants are also considered “new energy.”

In December 2017, the South Korean government released a new 15-year “Plan for Electricity Supply and Demand” that confirms its intention to shift electricity generation away from coal and nuclear towards more renewables (Ministry of Trade, Industry and Energy, 2017a). Specifically, the plan includes an objective to increase the share of renewable electricity generation in 2030 to 20%, from the 10% targeted by the RPS in 2024. The plan also takes into account a projected peak electricity demand in 2030 at 100.5 GW, which is 11% lower than the last edition of the plan, as the economy is expected to grow at a slower pace than two years ago. The current power capacity surplus (generated by recently built coal-fired power plants) provides headroom for a rapid build-out of renewable energy generation (E3G, 2018) that also represents an opportunity for Korean companies to expand into the renewables market. The plan also revised the estimated electricity demand for 2030 from 657 TWh (as defined in 2015) to 579.5 TWh (Ministry of Trade, Industry and Energy, 2017b).

In May 2017, responding to growing concerns over air quality, the government had announced that it would bring forward the shut-down of ten old coal-fired power plants—originally scheduled for 2025—to 2022 (Reuters, 2016) and also reconsider the nine coal-fired power plants which were seeking permits or under construction at that time. The Moon administration has only secured an agreement to convert two of the new plants to gas (E3G, 2018) and, as the new projections show a slight increase of coal-fired capacity by 2030 (from 36.8 GW to 39.9 GW), it suggests that the remaining plants will be built.

The plan also indicates that the government intends to expand its total gas-fired capacity from 37.4 GW to 47.5 GW by 2030 (a significantly lower level than previously announced, probably partially due to the expected lower electricity demand level) while confirming the shift away from its current nuclear-centred energy policy. It intends to reduce the share of nuclear electricity generation from 30% in 2015 to 24% in 2030, and phase out nuclear power in the long term.

In summary, the government plan would result in an electricity generation mix in 2030 based on 23.9% nuclear, 36.1% coal, 18.8% natural gas and 20% renewable energy (Ministry of Trade, Industry and Energy, 2017a). The significant difference with previous targets comes from the drop in natural gas-based generation (27% in previous announcement) that is mostly compensated by the share of coal-based generation remaining very high (+14% compared to previous announcement). Even though the renewable energy target is an encouraging signal, the government has to do more to shift its power sector away from fossil fuels.

The impact of the new “Plan for Electricity Supply and Demand” is not quantified in CAT’s analysis of South Korea’s current policy projections, due to the lack of laws or measures to implement them. The CAT estimates that if fully implemented (and taking into account the expected lower level of electricity demand highlighted above), these announcements would lead to a 53 to 69 MtCO2e/year (20%-24%) reduction in electricity-related emissions under current policies in 2030 (refer to “Planned policy projection” on the graph above). This is equivalent to a 7–9% reduction in total GHG emissions excl. LULUCF in 2030, compared to the projection under current policies.

Transport

In 2009, South Korea set a light-duty vehicle emissions standard of 140 gCO2/km in 2015. In December 2014, this was strengthened to 97 gCO2/km by 2020 (TransportPolicy, 2015). The South Korean Government is also pushing the uptake of electric vehicles (EV), with a goal of having 250,000 EVs on the road by 2020, through subsidies of up to US$12,000 per vehicle; local authorities also offer an additional subsidy of up to US$10,000 per vehicle (Financial Times, 2017). The government is also investing in a programme to improve charging infrastructure. The number of annual EV sales doubled from 2015 to 2016 to nearly 6,000.
