During London Climate Action Week, LSEG will host a closed-door roundtable in partnership with the UN Sustainable Stock Exchanges (UN SSE) Initiative and S&P Global Energy to explore the intersection of global carbon markets, energy security and decarbonization.

The evolving global energy landscape is placing decarbonization at the centre of discussions on energy security, climate action and sustainable finance. As governments, markets and companies seek to accelerate the transition to a low-carbon economy, questions remain about the role international carbon markets can play in driving emissions reductions and mobilizing climate finance.

While carbon markets have helped accelerate decarbonization in some regions and sectors, their development at the international level remains fragmented. Greater coordination and market development may be needed to support global emissions reductions, strengthen liquidity, and channel much-needed climate finance from the Global North to the Global South.

The discussion will focus on:

• The implications of Carbon Border Adjustment Mechanisms (CBAMs) for global carbon markets;
• How to build liquidity across regionally fragmented and structurally different carbon markets;
• The contribution carbon markets can make to global decarbonization as energy security becomes an increasingly central policy priority; and
• Whether existing international mechanisms, including Article 6 of the Paris Agreement and CORSIA, are sufficient to meet expected demand, and what further action is needed to scale carbon markets.
