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.

2030 NDC

Viet Nam updated its NDC in September 2020, pledging a 9% (unconditional) to 27% (conditional) reduction in greenhouse gas (GHG) emissions below business-as-usual (BAU) levels by 2030. Viet Nam’s conditional target is equivalent to around 748 MtCO₂e/yr excluding LULUCF, or a 100% increase above 2015 emission levels – higher than Viet Nam’s current policy pathway.

Fair share

Under the Paris Agreement, international support, including finance, technology transfer and capacity building will be needed for Viet Nam to close the emissions gap between its fair share and its domestic emissions pathway.

Net zero

Viet Nam committed to net zero emissions by 2050 at COP26 and is in the process of developing its long-term climate strategy. Our projections show it could reduce around 92% of its CO₂ emissions from 2015 levels by 2050, and 73-79% of its total GHG emissions, excluding the land sector (LULUCF).¹ On the road to net zero GHG, Viet Nam will need to balance its remaining emissions through LULUCF sinks, expanding its carbon sink.

Decarbonisation

The largest share of emissions reductions will take place in the energy sector, as this sector is responsible for the majority of emissions. Decarbonisation efforts are required in the power, buildings, industry and transport sectors as described below.

Remaining emissions

Under all 1.5°C compatible pathways, emissions in the agriculture and waste sectors will decline but cannot be fully eliminated. Ambitious mitigation policies will be required in these sectors, in addition to carbon dioxide removal (CDR) approaches in other sectors, to offset the remaining emissions and ensure net zero GHGs can be reached.

Sectors

Power

Our analysis of 1.5°C compatible pathways indicates that the carbon intensity of power will need to be reduced by 88-93% by 2030, compared to 2017 levels. The power sector needs to be fully decarbonised by 2036 at the latest. The decarbonisation would primarily be driven by a high uptake of renewable energy, rising from 45% in 2017 to 93-95% in 2030.
At COP26, Viet Nam pledged to phase out coal by the 2040s. 1.5°C compatibility would require phasing out coal and gas from the power sector by around 2030 and 2034 respectively.
Despite draft plans to cancel some coal fired power generation, Viet Nam has a large coal pipeline in its draft 8^th Power Development Plan, that will increase Viet Nam’s reliance on imported coal.² Initiatives such as the COP26 pledge may eliminate these plans.
Viet Nam also plans to ramp up natural gas with a pipeline of around 26 GW additional capacity between 2021-2026, which would lock in a carbon intensive energy system and risk expensive stranded assets.³
Viet Nam has huge renewables potential, and could become a regional leader in solar power (especially when deployed in the agriculture sector) and offshore wind.⁴ Our analysis suggests that renewable energy could provide 100% of Viet Nam’s electricity by 2040.

Buildings

All 1.5°C scenarios show an immediate decline in building sector emissions and the sector could achieve a 1.5°C compatible pathway if deploying 90% power share by 2030, and 96% by 2050, when in tandem with a high renewable energy percentage of the power mix.
The emissions from Viet Nam’s buildings sector could reach net zero by 2037-2049. Full decarbonisation of this sector could be achieved rapidly following a low energy demand scenario.
Viet Nam would need to phase out fossil fuels and replace wood and coal stoves and heating/cooling appliances with energy efficient electric appliances while scaling up renewable energy in the grid.

Transport

To be in line with a 1.5°C compatible pathways, transport emissions need to peak by 2025 or sooner and decrease by 50% in 2030 compared to 2019 levels to reach zero emissions by 2050.
1.5°C scenarios show that no or low-emissions fuels (electricity, hydrogen and biofuels) could take up to 21% share of transport energy demand by 2030 and 71-100% by 2050, decarbonising the sector if produced from renewable energy.
The government has recently developed plans to encourage electric vehicle uptake such as a reduction of the excise tax and registration fees for battery powered electric cars.
Viet Nam would need to implement further policies to reduce emissions from the transport sector to reduce dependence on oil and transition to electric vehicles, as well as support a modal switch to zero emissions transport.

Industry

The industry sector requires substantial decarbonisation efforts as emissions from industrial processes have increased 140% over the past decade. The rise is mainly attributable to steel and ammonia production. Low/zero carbon ammonia and steel can be produced using green hydrogen which is made using renewable energy sources.
Almost all 1.5°C scenarios show direct CO₂ emissions from the industry sector’s energy demand declining pretty much immediately.
In 2017, electricity (25%) and biomass (26%) represented 51% share of the industry sector energy mix. Electricity, hydrogen and biomass see an increase to 64-65% in 2030 in the industry energy mix and 76-95% in 2050.

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. ↩
