Brunei Darussalam's 3rd Nationally Determined Contribution (NDC 3.0).

The 3rd NDC of Brunei is a multi-sectoral document, covering the implementation period 2026–2035. The main objectives outlined in the document are as follows (i) achieve a 20% reduction in greenhouse gas (GHG) emissions by 2035, relative to a Business-As-Usual (BAU) scenario, using 2015 as the baseline year, alligned with Brunei’s obligations under the Paris Agreement to enhance climate ambition and reduce national emissions; (ii) align climate actions with national strategies to ensure sustainable, climate-resilient economic growth; (iii) implement ten strategic approaches, including 6 mitigation measures (reducing industrial, transport, power, and waste emissions; expanding renewable energy; and increasing forest cover), and 4 cross-cutting strategies (carbon pricing mechanisms, adaptation and resilience enhancement, comprehensive carbon inventory, and public climate awareness); (iv) promote an inclusive and participatory climate Governance, strengthening coordination among ministries, private sector, NGOs, and communities through a whole-of-nation approach under the Brunei National Council on Climate Change (BNCCC); (v) enhance adaptation and resilience, also developing a National Adaptation Plan (NAP) focused on the following 6 priority sectors (1) agriculture and food security; (2) biodiversity and environment; (3) health and livelihood; (4) infrastructure and urban resilience; (5) marine and coastal protection; (6) water resources. The new target is conditional and contingent on technological maturity and effective international cooperation.
More in detail, the six mitigation strategies targeting the reduction of greenhouse gas (GHG) emissions are (1) reduce industrial emissions by improving efficiency and emission controls in the oil, gas, and manufacturing industries; (2) increase forest cover through afforestation, reforestation, and conservation of forest land (aiming to conserve up to 55% of land as rainforest); (3) minimise emissions from land transportation by introducing electric vehicles, improving public transport, and encouraging low-emission mobility; (4) boost the share of renewable energy by promoting solar and other renewable sources in the national energy mix; (5) reduce emissions from power generation by improving efficiency in energy production and transitioning from fossil fuels; (6) reduce emissions from waste by improving solid waste management, recycling, and waste-to-energy initiatives. As for the 4 cross-cutting strategies, they aim to support long-term mitigation and adaptation and are (1) explore carbon pricing mechanisms assessing carbon trading or taxation to incentivize emission reductions; (2) enhance adaptation and resilience strengthening preparedness and recovery systems to manage climate impacts; (3) maintain a comprehensive carbon inventory establishing robust data systems for monitoring, reporting, and verification (MRV) of emissions; (4) foster climate awareness and education promoting public understanding and participation in climate action.
