…actions to deliver 1.5 °C-aligned energy transitions; and supporting the next round of Nationally Determined Contributions under the Paris Agreement – while deepening existing cooperation on data and capacity building. The IEA and the UNFCCC are building consensus on actions to deliver 1.5 °C-aligned energy transitions; and supporting the next round of Nationally Determined Contributions under the Paris Agreement – while deepening existing cooperation on data and capacity building. The global energy system is the bedrock of modern economies and societies – providing power to everywhere we live and work. Yet the production and consumption of energy is also…

…cost of capital and profit dynamics. We also explore how capital markets and innovative financing instruments can drive greater investment in the energy sector – especially in emerging and developing economies, where data is often limited. Participants representing a diverse range of financial institutions are invited to attend an annual event hosted at the IEA headquarters in Paris, and regional summits – the latest held in Singapore – are also organised to encourage broad participation across geographies.

Energy and Gender
…vital energy consumers, producers and decision-makers who make a crucial contribution to global energy security and energy transitions. Building a more secure, fair and equitable energy future hinges on their active participation.Recognising this, the IEA’s Member countries have asked the Agency to focus on key issues at the nexus of energy and gender, from improving gender data collection to expanding analysis of the gender dimensions of energy policies. This work continues to expand and develop. The initiative, which was formerly known as C3E International, works to improve gender-disaggregated data in the energy sector, honour women in…
