monitoring networks. Concurrently, the B&R Climate Cooperation Forum institutionalized mechanisms for
aligning emission reduction targets and formulating green investment standards, fostering a more
coordinated regional approach. Against this backdrop of intensified climate action, however, projections
indicate that CH emissions are likely to continue rising in B&R countries. The following recommendations
4
are proposed to achieve effective CH emission control and support sustainable economic growth:
4
(1) Promoting industrial intervention and technological innovation: CH emissions from B&R countries
4
contributed significantly to global totals, particularly from sectors such as agriculture, petroleum, chemical,
and non-metallic mineral products, construction, financial intermediation, and commercial activities. B&R
countries should strengthen cooperation in renewable energy deployment by jointly investing in solar,
wind, and hydroelectric projects. For traditional energy sources, such as coal and natural gas, policies
should promote clean technologies, including carbon capture and storage (CCS) for coal-fired power plants
and advanced natural gas purification techniques. Emission intensity has played a crucial role in facilitating
decoupling in recent years, indicating that countries with lower technological levels possess greater
abatement potential. By seizing the opportunities arising from technological innovation and industrial
transformation, accelerating industrial structure optimization and upgrading, and improving production
efficiency, countries are expected to effectively reduce CH emissions.

(2) Addressing regional inequality and uneven distribution: Technological and financial constraints in some
countries widen the gap in CH emissions between PBEs in H-H income groups and CBEs in L-L income
4
groups, even as the divergence between PBEs and CBEs within H-H income countries narrows. To promote
CH emission reduction, the international community should strengthen cooperation through policy
4
coordination and joint actions. Policy coordination could involve harmonizing emission standards and
regulatory frameworks across B&R countries, while joint actions could include collaborative research and
development programs focused on CH capture and utilization technologies. Weak decoupling remains a
4
challenge for reducing CH emissions across the B&R countries. In the context of global economic
4
integration, uneven distribution and potential fragmentation of technologies and resources, despite
increasing economic linkages, may weaken collective climate action. Strengthening cooperation in
environmental protection, promoting clean energy projects, developing ecological infrastructure, and
facilitating green trade will reduce emission intensity across the B&R region and help narrow the emissions
gap with the rest of the world.

(3) Strengthening regional cooperation and capacity building: Effective CH emission reduction requires
4
close cooperation among countries and enterprises along the energy supply chain, with an emphasis on
capacity building, standardization of monitoring technologies and criteria, data-sharing platforms,
innovation in emission reduction technologies, and joint infrastructure development. Regional agreements
on monitoring standards will ensure consistent data quality, while shared data platforms will promote
transparency and informed decision making. Joint innovation initiatives focused on CH detection and
4
mitigation can accelerate technological progress. Additionally, a tiered approach can maximize
effectiveness: high-income B&R countries can fund R&D and share advanced CH4 reduction technologies,
while low-income countries receive training in CH management and support for basic monitoring. When
4
combined with reinforced international cooperation, sustainable practices, improved regulatory
frameworks, advocacy for green B&R initiatives, and public awareness campaigns, these measures will
significantly reduce CH emissions and foster a more sustainable environmental future in the B&R region.
