This year at Climate Week at NYC, what struck me was not a single announcement or commitment, but how the centre of gravity has shifted across several debates. A decade ago, energy security discussions focused largely on oil, gas and geopolitical exposure. This year, they centred on transmission, storage and dependable clean power. AI’s disruption moved beyond technology, shaping conversations around electricity infrastructure, and further broadening the questions about its impact on. Corporate climate discussions focused less on targets and more on procurement, governance and capital allocation.

Taken together, these conversations suggested a critical shift. Climate action is increasingly being shaped by the systems, institutions and capabilities that determine not only the scale of the progress, but whether the journey can take people along with it inclusively.

Energy security and climate action are converging

The renewed focus on energy security during Climate Week came as little surprise. The conflict in West Asia reinforced how deeply the global economy remains exposed to fuel markets, shipping routes and geopolitical disruptions. For India, which imports roughly 85 per cent of its crude oil and around half of its LNG requirements, energy security remains an immediate economic priority.

What stood out this year was the prominence of clean energy within those discussions. Questions of energy security increasingly encompassed transmission networks, storage, domestic manufacturing, supply chains and round-the-clock renewable power. Clean energy is being viewed through the lens of national resilience, industrial competitiveness and strategic capability.

India’s trajectory reflects that evolution. More than 300 GW of non-fossil capacity now sits within a power system of roughly 552 GW. Attention is increasingly directed towards the infrastructure and industrial capabilities that determine how effectively that capacity can support economic growth and reduce exposure to external shocks. But energy security will ultimately also be defined by people: whether energy is reliable and affordable, and whether the capabilities being built create jobs and economic opportunity.

Artificial intelligence featured prominently in discussions about competitiveness, productivity and growth. Strikingly, those conversations frequently converged on electricity infrastructure. Data-centre electricity consumption is expected to rise from roughly 460 TWh today to more than 1,000 TWh by the end of the decade, comparable to the annual power consumption of economies such as Japan or Germany.

The constraint is increasingly physical. More than 2,500 GW of power, storage and large energy-use projects are waiting for grid connections worldwide, more than eight times India’s current renewable capacity. A data centre can be built in one to three years, while major transmission infrastructure may take five to fifteen.

The significance extends beyond technology. Substations, transmission corridors, storage and grid modernisation are becoming critical determinants of digital competitiveness, industrial growth and climate progress. AI is accelerating demand for computing power and the energy systems that underpin economic growth.

Its human impact is also becoming visible. Corporate functions that drove AI adoption for productivity are now experiencing changes in their own work, while technical judgement, physical execution and human relationships remain essential.

The Global South’s investment challenge

The past month has offered a stark reminder of what is at stake. From floods and storms to heat-related disruptions, communities across the Global South have continued to absorb the economic costs of a changing climate even as investment remains concentrated elsewhere. Global energy-transition investment reached US$2.4 trillion in 2024, yet roughly nine of every ten dollars flowed to advanced economies and China, leaving many climate-vulnerable countries competing for a small share of global capital.

What emerged repeatedly in discussions was the importance of market credibility. Capital follows confidence. Investors look for transparent procurement, credible institutions, bankable off takers and policy consistency. India’s experience illustrates the point. Competitive renewable-energy costs were built on years of auction design, transmission planning, regulatory visibility and institutional trust. Markets attract capital when investors can see a credible path from ambition to execution. The quality of that foundation often determines the cost and scale of climate finance.

Corporate climate action enters an age of accountability

Corporate climate action is encountering a more demanding form of scrutiny. Several years ago, the debate often centred on whether companies had targets. This year, the focus was on what those targets are producing. Investors, customers and regulators increasingly want evidence that climate commitments are influencing procurement, capital allocation, executive incentives and supply-chain decisions.

One statistic captures why this matters. For many companies, the vast majority of emissions sit beyond their direct operations. In one example discussed during the week, Scope 3 emissions represented roughly 96 per cent of the total footprint. That reality places procurement, supplier engagement and product design at the centre of climate performance. The discussion is becoming less about commitments and more about consequences. Accountability increasingly resides in the decisions that businesses make every day.

For all the discussion about infrastructure, finance and technology, Climate Week repeatedly returned to people. Climate action becomes real when it creates visible benefits, from reliable energy and stronger local economies to new livelihoods and opportunities to participate in growth. India’s renewable-energy sector already supports more than a million jobs. The next phase of growth will depend on who can access opportunities across manufacturing, storage, construction and operations. As AI reshapes knowledge-based work, the energy transition will continue to depend on people who build, operate and maintain physical systems, combining enduring human capabilities with new technologies.

Perhaps that was the clearest message from New York. Climate outcomes are being shaped where energy systems, markets, institutions and people meet. Climate action remains the destination. The path will be determined by the capabilities inclusive societies build, the choices they make and the opportunities they create along the way.
