Indonesia Ambition gap

What is Indonesiaʼs pathway to limit global warming to 1.5°C?

1.5°C compatible pathways

Indonesia’s updated NDC reiterates its 2015 target pledges stated in its 2015 NDC of an unconditional emissions reduction of 29% below business as usual (BAU) levels, and a conditional contribution of 41% below BAU by 2030.1

Indonesia’s conditional NDC would result in an increase in GHG emissions excluding land use, land use change and forestry (LULUCF) of 99-100% above 2015 levels by 2030.1 Modelled pathways show that, to be 1.5°C compatible, emissions excluding LULUCF need to decrease 30-48% below 2015 levels by 2030 (between 435-581 MtCO₂e per year until 2030). Achieving an emissions sink from the LULUCF sector however is critical to achieving a Paris Agreement compliant target, corresponds to a reduction of around 84-89% below 2030 including LULUCF or 63-75% below 2015 levels.14

Indonesia will very likely meet its NDC targets under current policies. This is primarily due to the very high emissions baseline scenario used for the basis of the NDC target definition meaning that the country will likely achieve its targets without any additional efforts while still doubling its emissions (excl. LULUCF).

While Indonesia’s current policies would allow for emissions far above from 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.1

Long term pathway

Indonesia is one of the few developing countries to publish its ‘long-term strategy for low carbon and climate resilience 2050’. While it aims at reaching net zero by 2060, the level of emissions reduction under its “long term Paris compatible scenario” (LCCP) remain insufficient compared to analysed 1.5°C compatible models here.2

According to Bappenas, Indonesia’s National Development Planning Agency, a more ambitious emission reduction pathway leading to net zero emissions by 2045 would be economically and socially beneficial.3

1.5°C compatible pathways show that by 2050, GHG emissions excluding LULUCF could be reduced to 150-216 MtCO₂e/yr or 74-82% below 2015 levels, driven primarily through emissions reductions in the energy sector, but also in waste and agriculture.29 The remaining emissions would need to be balanced through the use of negative emissions such as land sinks up to -216 MtCO₂e/yr by 2050. This stands in contrasts with Indonesia’s long-term strategy which would still allow emissions to increase by 2050, by around 1% compared to 2015 levels.2

Avoiding the need for negative emissions at this scale would need faster decarbonisation in the other energy-using sectors. In addition, reaching larger shares of renewables earlier would reduce reliance on negative emissions technologies in the second half of the century under a 1.5°C domestic pathway. The land use sector is important in Indonesia, and emissions from LULUCF could be brought to zero by around 2030 and become an emission sink thereafter leading to net zero GHG including LULUCF being achieved from around 2040.14

29 While global cost-effective pathways assessed by the IPCC Special Report 1.5°C provide useful guidance for an upper-limit of emissions trajectories for developed countries, they underestimate the feasible space for such countries to reach net zero earlier. The current generation of models tend to depend strongly on land-use sinks outside of currently developed countries and include fossil fuel use well beyond the time at which these could be phased out, compared to what is understood from bottom-up approaches. The scientific teams which provide these global pathways constantly improve the technologies represented in their models – and novel CDR technologies are now being included in new studies focused on deep mitigation scenarios meeting the Paris Agreement. A wide assessment database of these new scenarios is not yet available; thus, we rely on available scenarios which focus particularly on BECCS as a net-negative emission technology. Accordingly, we do not yet consider land-sector emissions (LULUCF) and other CDR approaches.

30 Fossil fuel with CCS in the power sector are very likely to emit at the very least a tenth of the average emissions compared with an installation without CCS and therefore cannot be considered a zero or low-carbon technology. Costs of CCS in the power sector have remained stagnant over the last decade. CCS technologies in the power sector also have a non-trivial sustainability footprint in terms of increased water use, higher fossil resource demands and consequential mining and production footprint, and in general do not address local air pollution concerns. The CCS technologies are also uncertain regarding security of storage over very long periods of time and the need for legal structure to allow it to happen.

Energy system transformation

The energy sector will need to contribute the largest emissions reductions to 2030, through a shift from fossil energy use to zero and near-zero carbon sources. This will require a reduction of the current 73% share of coal, oil and natural gas use in the primary energy mix to be 45-75% 2030, and around 6-57% by 2050.

To enable this reduction, Indonesia would need to considerably scale up renewable energy sources, from less than a quarter of all primary energy in 2019 to over two-thirds by 2050. This means an increase in absolute terms from 2.5 EJprimary in 2019 to 1.5–6 EJprimary in 2050. The lower value in this range would be consistent with the Paris Agreement only if nuclear power or fossil energy with CCS technology were to be introduced at significant scale in Indonesia’s power and industry sectors, reaching a share in primary energy of up to 22% by 2030 and 37% by 2050. Neither technology exists in the country today. To be on 1.5°C compatible pathway if Indonesia depends on CCS and nuclear, developments of these technologies would need to start imminently for completion within this timeframe, which seems very unlikely. Fossil energy with CCS is not currently viable anywhere globally. Both fossil energy with CCS and nuclear energy also have serious sustainability concerns and are not expected to be able to compete with renewable energy in economic terms. Indonesia’s National Action Plan on Climate Change recognised that CCS could contribute up to 40% of the targeted energy sector’s emission reductions. CCS is gaining attention in the country as Indonesia’s state owned oil and natural gas company, Pertamina is planning to install CCS facilities installation in two of its oil and gas fields.19,20

The power sector would see a complete phase-out of coal from around 2030 with a small amount (<<0.5 EJprimary) being used in other sectors until around 2040.21 Gas would phase out from power from around 2035, drawing down across all sectors towards the end of the century.
