What is Indonesia's pathway to limit global warming to 1.5°C?
Indonesia
Economy wide
To achieve a 1.5°C compatible pathway, Indonesia would need to peak and decline its GHG emissions immediately and reach 30-48% reductions below 2015 by 2030, an emissions gap of close to 1.3 GtCO₂e/yr
Indonesia's total GHG emissions excl. LULUCF MtCO₂e/yr
*Net zero emissions excl LULUCF is achieved through deployment of BECCS; other novel CDR is not included in these pathways

Graph description
The figure shows national 1.5°C compatible emissions pathways. This is presented through a set of illustrative pathways and a 1.5°C compatible range for total GHG emissions excl. LULUCF. The 1.5°C compatible range is based on global cost-effective pathways assessed by the IPCC SR1.5, defined by the 5th-50th percentiles of the distributions of such pathways which achieve the LTTG of the Paris Agreement. We consider one primary net-negative emission technology in our analysis (BECCS) due to data availability. Net negative emissions from the land-sector (LULUCF) and novel CDR technologies are not included in this analysis due to data limitations from the assessed models. Furthermore, in the global cost-effective model pathways we analyse, such negative emissions sources are usually underestimated in developed country regions, with current-generation models relying on land sinks in developing countries.
Methodology
Data References
-
2030 NDC
Indonesia’s updated NDC reiterates its first 2030 target of an unconditional emissions reduction of 29% below business as usual (BAU) levels, and a conditional reduction of 41% below BAU by 2030.1
Conditional NDC
Indonesia’s conditional NDC target would result in an increase in GHG emissions excluding land-use, land-use change and forestry (LULUCF) of 99-100% above 2015 levels by 2030.2
Fair share
While Indonesia’s current policies would allow emissions far above its “fair share” range as assessed by the Climate Action Tracker, the country will need to receive international support to close the gap between its fair share and domestic emissions pathway.3
Long-term strategy
Indonesia’s Long-Term Strategy, released in July 2021, aims to peak emissions in 2030 and achieve net zero by 2060 or sooner.4,5
Net zero
This is not aligned with the analysis undertaken by Bappenas, Indonesia’s National Development Planning Agency, that proposed a more ambitious emission reduction pathway leading to net zero emissions by 2045 and indicating that reaching net zero earlier could be economically and socially more beneficial.6,7
2050 Ambition
Our analysis of 1.5°C compatible pathways indicate that by 2050 GHG emissions, excluding LULUCF, could be reduced to 150-215 MtCO₂e/yr or 76-79% below 2019 levels, driven primarily through emissions reductions in the energy sector, but also in waste and agriculture.8 This stands in contrast with Indonesia’s long-term strategy’s “long term Paris compatible scenario” (LCCP), which would still allow an increase in emissions of around 1% compared to 2015 levels by 2050.9
Land-use and forestry
LULUCF emissions will play a major role in the country’s trajectory to reach net zero. Indonesia will need to implement stringent policies to reduce deforestation. In 2016, land use sector accounted for 43% of Indonesia’s total emissions, as a result from extensive deforestation for agriculture.
Sectors
Power
-
1.5°C compatible pathways illustrate that renewables in the power sector need to reach 70–75% by 2030 and 99–100% by 2050.
-
A high uptake of renewables can bring down emissions intensity to 105–157 gCO₂/kWh from the 2019 level of 761 gCO₂/kWh by 2030, thus reducing the reliance on negative emissions technologies such as bio energy carbon capture and storage (BECCS) and carbon capture and storage (CCS). Indonesia plans to equip 76% of its coal power plants with CCS to achieve net zero emissions. However, relying on CCS comes with high costs and uncertainty.10,11
-
Indonesia plans to retire coal-fired power plants which are older than 20 years and stop building new coal-fired plants after 2023.12 In line with this, its primary electricity distribution company, Perusahaan Listrik Negara (PLN), has recently committed to providing “carbon neutral electricity” by 2050. This is in sharp contrast to Indonesia’s huge coal pipeline of over 30 GW of coal-fired power capacity that is already financed and/or under construction. It also directly contradicts with analyses showing a coal phase-out by 2030, followed by a gas phase-out between 2035 and 2038 are needed.13
Buildings
-
Energy consumption in Indonesia’s buildings sector t accounts for 3.8% of direct CO₂ emissions and 20.7% of indirect CO₂ emissions.
-
The total final energy consumption of the residential building sector peaked in 2007 and has since been in decline, falling by 43% to 2019. During the same period, residential electricity demand increased by around 120%.
-
1.5°C compatible pathways illustrate that the share of electricity demand in the building sector could be 54-76% in 2030, and 92-95% by 2050, under different scenarios.
-
The share of solid biomass, mainly from palm oil residue, has been significant for meeting the energy demand of buildings, 52% in 2020. All scenarios however see a rapid decline in demand of solid biomass, reaching 4-25% by 2050.
Transport
-
Indonesia’s transport sector is completely dependent on fossil fuels, particularly oil. The share of electricity in energy use is insignificant.
-
A 1.5°C compatible pathway illustrates a rapid electrification of the transport sector, with a forecasted increased share of electricity demand of 6-7% by 2030 and 23-48% by 2050.
-
All scenarios show peaking of fossil energy demand from transport sector by 2020.
-
The government is providing a policy push for an increased uptake of electric vehicles, biofuel blending up to 40% by 2022 and investing in infrastructure development for mass transit. However, the bulk of biofuels are palm oil, and the cultivation of palm trees is strongly linked to deforestation and peat land destruction.
Industry
-
Growth of the industrial energy demand in Indonesia has remained volatile since 2008, however has increased by 48% between 2008-2019.
-
The electricity demand in industry is steadily increasing since 1990, at an annual rate of 6.4%, with the industry’s share in total electricity demand registered at 36%, in 2019.
-
Improved energy efficiency is key to mitigating industry emissions, with all scenarios demonstrating a rapid decline in emissions intensity of the industrial sector to 75-115 MtCO₂/yr by 2030 and 14-59 MtCO₂/yr by 2050.
-
Industrial process emissions are shown to be increasing since 1990, however decline significantly from 2025 in 1.5°C compatible pathways.
