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.

Historical emissions

Historical emissions from 1990 to 2016 were taken from Chile’s Third Biennial Update Report to the UNFCCC (Ministerio del Medio Ambiente, 2018), in which emissions are available in Global Warming Potentials (GWPs) from the IPCC Fourth Assessment report.

Pledges and targets

The 2020 pledge did not state a reference pathway, but specifically states that it will be a reduction from Business-As-Usual (BAU) as projected in 2007. We have therefore calculated Chile’s 2020 pledge using as reference the 2007 BAU scenario from Boston Consulting Group (2013). This pathway closely resembles the 2007 BAU presented by Searle (2011) on behalf of the Chilean Government in the same context. This BAU scenario is reported in GWPs from the second assessment report (SAR). We have converted total emissions excl. LULUCF from this scenario to AR4 GWPs by using a factor estimated from Chile’s National Inventory System gas by gas inventory (Ministerio del Medio Ambiente del Gobierno de Chile, 2018). This reference scenario has not been harmonized to historical emissions.

Both targets presented in Chile’s NDC were quantified based on the GDP assumptions from the GHG Mitigation Plan for the Energy Sector (Ministerio de Energía, 2017b), which projects an average 3% growth per year. The current policy projections are based on the same assumptions on GDP growth.

While the GDP projections in the Mitigation and Action Plans and Scenarios (MAPS) scenarios are specifically mentioned in Chile’s NDC submission, we assume that the updated GDP numbers from the Mitigation Plan should be used for quantifying absolute emission levels resulting from the targets. Chile’s NDC intensity targets are very sensitive to the projected GDP growth assumptions. If a slightly higher GDP growth rate is used, the NDC target shifts up (less ambitious, allowing for more emissions) potentially resulting in Chile achieving both its NDC targets with the current policy scenario.

We have estimated a range for Chile’s emissions levels (excluding LULUCF) under the recently announced 2050 carbon-neutrality target. Given that this target depends on the size of Chile’s forestry sinks in 2050, we have estimated a range based on its historical highest and lowest emissions/removals from forestry from Chile’s Third Biennial Update Report to the UNFCCC (Ministerio del Medio Ambiente, 2018).

Current policy projections

Current policy projections have been harmonized to historical emissions up to 2016.

We estimate total emissions as the sum of the agriculture, waste, energy and Industrial Processes and Product Use (IPPU) sectors. The first two sectors are taken from MAPS Chile (Línea Base 2013, PIB bajo) (Government of Chile, 2014). The base year of the MAPS Chile scenario is 2013, and it is based on macroeconomic projections from 2013 (low case GDP growth, an average annual GDP growth of 3% through 2030) and includes implemented policies up until 2013. The Industrial Processes and Product Use sector is quantified by assuming a continuation of historical emissions trends from the inventory due to lack of available national projections. The energy sector projections are taken from the Mitigation Plan’s current implemented policies scenario (Ministerio de Energía, 2017b). The policies included in this scenario include the Unconventional Renewable Energy Law (Law 20.257/2008), the carbon tax (Law 20.780/2014), and the results of electricity supply tenders as of December 2017 (Ministerio de Energía, 2017b). We have additionally quantified and subtracted the potential emissions reduction from Chile’s Electromobility Strategy as well as the recently announced first-phase of Chile’s coal phase-out plan from the Mitigation Plan current policy scenario.

Potential emission reductions from the Electromobility Strategy are quantified by estimating a range of private electric vehicle market penetration and urban electric bus fleet renewal.

  • For Light Duty Vehicles, we estimated a range for Chile’s future fleet based on different projections for LDV development and EV market penetration. Emissions reductions were then estimated from the total amount of conventional vehicles that could be replaced by electric ones.
    • For the lower end, we assumed historical private vehicle fleet from the Instituto Nacional de Estadísticas (Instituto Nacional de Estadísticas de Chile), total vehicle fleet projections from the Agencia Chilena de Eficiencia Energética (EBP Chile, 2018), and LDV projections from New Climate’s EV policy impact assessment tool (NewClimate Institute, 2018).
    • For the higher end, we linearly projected the LDV fleet by using the amount of electric vehicles expected by the government in 2050 (Ministerio de Energía, 2017a) and historical LDV fleet numbers from the IEA Global Outlook on EVs (IEA, 2018b) and from the Electromobility Platform launched by the government in April 2019 (Ministerio de Energía de Chile, 2019b).
  • For the urban electric bus fleet, we first estimated a range of electric vehicle fleet projections based on different assumptions outlined below. We then assumed the emissions reductions by using different factors such as the vehicle use and the consumption factor from various sources (Directorio de Transporte Público Metropolitano; Ecoscore; Ministerio de Transportes y Telecomunicaciones Chile; E2BIZ Consultores, 2017; EBP Chile, 2018).
    • For the lower end, we used the projections for urban electric buses in Santiago from the Chilean Association of Electricity Suppliers (in Spanish: Asociación de Generadoras de Chile; referred to as “Suppliers”) (E2BIZ Consultores, 2017). We extrapolated the evolution of the national urban electric bus fleet from those local projections and used the conservative scenario’s growth rate of the Suppliers’ report, which corresponds to a Business-As-Usual scenario. We also assumed that the total national urban bus fleet would remain stable as of 2019 onward, as the Suppliers did for the TranSantiago bus fleet.
    • For the higher end of the range, we linearly interpolated the historical electric urban bus fleet numbers from the Electromobility Platform (Ministerio de Energía de Chile, 2019b) and the expected amount of electric urban buses expected by the government in 2050 (i.e 100% of the urban bus fleet). The projection of the urban bus fleet in 2030 was obtained by using the historical urban bus fleet from the Subsecretary of Transport (Subsecretaría de Transportes) and extrapolated it to 2030 applying the population growth as a proxy.

The maximum emission reduction potential assumes that the electricity demand from electric LDVs and electric buses will be met by renewable sources. The minimum emission reduction potential assumes that the electricity demand will be met by increasing electricity generation from the grid using the same mix as in CAT current policy scenario.

Emissions reductions from the first stage of Chile’s coal phase-out plan were estimated using the chronogram published the Ministry of Energy (Ministerio de Energía, 2019). We first estimated electricity generation from those plants using capacity factors from an Inodú (2018) study prepared for the Ministry of Energy . We then estimated an average emission factor from coal-fired power plants in Chile between 2010 and 2016 from IEA data (IEA, 2018c, 2018a). Finally, we estimated emission reductions by multiplying the replaced electricity generation per year by the average emission factor assuming that these electricity generation would be replaced by non-conventional renewable energy sources as specified by Chile’s Ministry of Energy. The upper end of the range assumes that electricity generation from retiring coal-fired power plants will be replaced by gas-fired power plants. For this we estimated an average emissions factor from plans in Chile between 2010 and 2016 using data from the IEA (2018c, 2018a) .

Some newer policy developments such as the update on the Distributed Generation Law (also referred to as the “Net Billing” Law) (Law 20.571), which triples the capacity threshold for installed capacity for projects of self-consumption, are not quantified due to lack of available data.

Planned policy projections

Planned policy projections have been harmonized to historical data.

Additional to the current implemented policies scenario, Chile’s Mitigation Plan includes a scenario which is aligned to the 2050 Energy Strategy. We have added and adapted this scenario as a planned policy scenario. This scenario includes the targets of electricity generation from renewable energy of at least 60% by 2035 and 70% by 2050. Additionally, we have quantified and subtracted emissions reductions from the electromobility strategy using the same methodology as in the current policy scenario and the first and second stages of Chile’s coal phase-out plan. For the later we have assumed a linear retirement of coal-fired electricity generation. The upper end assumes that this generation will be supplied by gas, while the lower end assumes that the electricity generation from coal will be met by renewable energy sources.

Our analysis estimates that by implementing policies from the planned policies scenario presented on the Mitigation Plan, Chile will achieve its 2020 pledge, its unconditional and conditional NDC targets and could achieve its new proposed NDC unconditional target.

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). These GWPs are consistent with Chile’s Third Biennial Update Report to the UNFCCC (Ministerio del Medio Ambiente, 2018).
