Climate warnings are increasingly showing up as economic warnings.
On August 11, Reuters reported that severe drought and heat were disrupting agriculture, shipping and power generation across parts of Europe, while the United Nations has warned that climate-driven disasters are reaching “nightmare proportions”.
The latest data point to a difficult contradiction: clean-energy deployment is accelerating, but global energy-related emissions still reached a record in 2025.
Extreme Weather Raises Costs
The European wildfire season illustrates how physical climate risks can translate into financial losses. By July 22, fires had burned 254,388 hectares across the EU, according to the European Commission’s Joint Research Centre.
There were 1,254 fires, more than twice the 2006-2025 average of 569. Although the burned area was below the 270,449 hectares recorded by the same point in 2025, last year’s total ultimately became the EU’s worst wildfire season on record.
The economic consequences are already visible. Reuters reported on August 6 that wildfire-related costs across France, Spain, Greece and other affected countries had exceeded €15 billion this summer. The estimate includes property and infrastructure damage, firefighting, debris removal and insurance claims.
That matters for businesses because climate exposure is not restricted to companies directly operating in affected areas. Disrupted transport, damaged infrastructure, insurance losses and interruptions to agricultural production can spread costs through supply chains.
Clean Energy Gains Momentum
The energy transition, however, is moving faster than the emissions headline might suggest. The IEA estimates that global renewable capacity additions reached 800 GW in 2025, up 16% from the previous year. Solar PV accounted for more than three-quarters of the additions, with annual solar additions surpassing 600 GW for the first time.
India was among the faster-growing major markets. Its renewable capacity additions increased by almost 60% in 2025, driven by nearly 50 GW of new solar PV and more than 6 GW of wind capacity.
Yet this progress has not translated into an outright fall in global emissions. The IEA estimates energy-related CO2 emissions increased by about 0.4% in 2025 to nearly 38.4 billion tonnes. The increase was smaller than in previous years, but it still pushed emissions to another record.
India’s Energy Balancing Act
India’s position is particularly important because it has to expand energy access and electricity supply while lowering emissions intensity. The IEA says India’s energy-related emissions dipped in 2025, partly because an earlier and stronger monsoon reduced cooling demand and coal consumption, alongside continued renewable expansion.
That single-year decline should not be interpreted as a structural reversal. The IEA forecasts India’s power-sector emissions will rise by an average 2.4% annually between 2026 and 2030 as electricity demand increases, with coal remaining the dominant source of supply. At the same time, India’s power-sector CO2 intensity is projected to decline by an average 3.4% annually over the period.
This distinction is crucial. India’s economy can continue adding electricity demand while becoming less emissions-intensive, but absolute emissions can still rise if demand expands faster than clean generation replaces fossil-fuel generation.
Climate Risk Needs Investment
The pressure is unlikely to ease soon. The WMO forecasts global temperatures during 2026-2030 to remain between 1.3°C and 1.9°C above the 1850-1900 average. It also gives an 86% probability that at least one year during that period will exceed 2024 as the warmest year on record.
India’s exposure is significant. The World Bank says more than 80% of the country’s population lives in districts at risk from climate-induced disasters. Its latest study for India’s 16th Finance Commission also describes a broad rise in the frequency and intensity of extreme-weather events, including floods, droughts, cyclones, landslides and heatwaves.
For policymakers and companies, the implication is increasingly practical. Climate spending cannot be limited to emissions reduction. Power grids, transport networks, water systems, buildings, agriculture and insurance markets also need to withstand greater physical stress.
The UN’s warning is therefore not simply an environmental alarm. The emerging data suggest a broader economic challenge: the world is adding clean-energy capacity at record speed, but businesses and governments are simultaneously operating in a climate where physical risks and their associated costs are becoming harder to treat as exceptional events.
