India is the world's most populous democracy and a rapidly growing economy with enormous energy needs. It has made substantial investments in solar power through its National Solar Mission but remains the world's third-largest emitter and heavily dependent on coal. India argues strongly that developed nations must bear the greater burden of the energy transition, and it resists regulatory frameworks it sees as limiting its right to development.

Indonesia is a large archipelagic republic and one of the world's largest emitters due to deforestation and coal use. It has significant renewable energy potential, particularly in geothermal energy, but faces economic and political obstacles to rapid transition. Indonesia tends to take a pragmatic, development-first stance in environmental negotiations, supporting green goals in principle while seeking flexibility on timelines.

Iran is an Islamic republic under theocratic governance, with an economy heavily reliant on oil and gas exports that have been constrained by decades of international sanctions. Its domestic energy infrastructure is largely fossil fuel-based, and it has little incentive to support frameworks that would reduce global demand for hydrocarbons. Iran tends to be dismissive of Western-led environmental initiatives, which it views through a lens of geopolitical suspicion.

Japan is a constitutional monarchy with a highly developed economy and a sophisticated approach to environmental technology, including advances in battery storage and energy efficiency. However, following the Fukushima disaster, Japan increased its reliance on fossil fuels after shutting down nuclear capacity, complicating its climate commitments. It supports international cooperation on renewables but has been cautious about aggressive regulatory timelines.

Kazakhstan is a Central Asian republic with an economy dominated by oil, gas, and coal extraction. It has taken some steps toward renewable energy development but remains structurally dependent on fossil fuels and has limited political incentive to adopt ambitious environmental commitments. Kazakhstan tends to align with Russia on energy and climate issues and is cautious about binding international environmental regulation.

Kenya is a presidential republic in East Africa and a recognised leader in renewable energy on the continent, with geothermal and wind projects like Lake Turkana powering a significant share of its grid. Kenya also bears the consequences of being a destination for illegally dumped electronic waste from wealthier nations, making it both an advocate for green technology and a victim of inadequate global e-waste enforcement.

Mexico is a federal republic with a mixed energy profile, combining significant oil production with growing renewable capacity. It has made international commitments on climate but domestic energy policy has recently shifted back toward fossil fuels under state energy companies. Mexico occupies a middle position in environmental debates, acknowledging the urgency of the issues while defending its sovereign right to manage its own energy sector.

Nigeria is a federal republic and Africa's largest oil producer, giving it a complex position in energy debates. While it receives significant volumes of e-waste from Europe and Asia and suffers serious environmental damage as a result, its government remains economically dependent on fossil fuel revenues. Nigeria broadly supports stronger e-waste regulation but is cautious about renewable energy frameworks that could affect its oil export income.

Norway is a constitutional monarchy with a social democratic tradition and one of the most advanced renewable energy systems in the world, with hydropower supplying over 90% of its electricity. Despite its clean domestic energy record, Norway is a major oil and gas exporter, creating a degree of tension in its international environmental posture. It is nonetheless a generous funder of global climate and conservation initiatives.

Russia is a federal state with strong authoritarian characteristics under President Vladimir Putin, and one of the world's largest producers and exporters of fossil fuels.
