In 2017, Malaysia’s building sector – both residential and commercial – consumed 14.3% of the total energy and 53% of electricity.¹² Since 2005, the building sector’s energy demand has grown steadily at 3.4% annually whereas electricity consumption has increased at 6.4% during the same time period.⁵ The share of electricity in the building sector energy demand under 1.5°C compatible pathways could reach 91-92% in 2030 and 96-98% by 2050 under different scenarios. All scenarios see a rapid decline in direct CO₂ emissions in the sector to around 2 MtCO₂/yr by 2030 and 0.3-0.4 MtCO₂/yr by 2050 from 2019 level of 3.5 MtCO₂/yr, mostly driven by increased electrification rate with high share of renewables in the power mix and increased energy efficiency. Some pathways show that the building sector could be decarbonised by 2033.

Malaysia’s Green Technology Master Plan (GTMP) 2017-2030 has created a framework which facilitates the mainstreaming of green technology into existing initiatives e.g. Green Building Index (GBI), sustainable construction practices and green product directories in building materials. This plan aims for a 1 MtCO₂e emissions reduction from the sector by 2020 from 2013 level (around 22% of 2013 emissions levels).

¹⁷ Using Global Warming Potential AR4.

¹⁸ 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 which developed countries will need to implement in order to counterbalance their remaining emissions and reach net zero GHG are not considered here due to data availability.

¹⁹ LULUCF emissions are projected to be -227 MtCO₂e in 2030 following a business-as-usual scenario reported in Malaysia’s Second Biennial Report.

²⁰ As stated in the NDC. However, Malaysia participated in the Clean Development Mechanism and Voluntary Carbon Market, but these are not accounted as national mitigation actions as noted in the Biennial Report 3.

²¹ Fuel-efficient vehicles is defined as hybrid, electric vehicles and alternatively fuelled vehicles such as Compressed Natural Gas (CNG), Liquefied Petroleum Gas (LPG), biodiesel, ethanol, hydrogen and fuel cell.

²² The total financial support required totals USD 71,900,000, in additional to technical and capacity building support.

²³ In some of the analysed pathways, the energy sector assumes already a certain amount of carbon dioxide removal technologies, in this case bioenergy carbon capture and storage (BECCS).
