Scaling Up Transition Finance Executive Summary
Successful transitions need finance that goes where the emissions are Actions by the world’s most emissions-intensive sectors, companies, and countries are crucial to placing the world on a sustainable pathway. Yet, investments that could deliver meaningful reductions in their environmental footprint often do not receive sufficient financial support. Currently, finance is drawn heavily to certain “green” assets and activities—most prominently renewable power. While vital, these investments alone cannot deliver all the changes needed to cut global emissions, especially in areas where clean technologies are not yet commercially available or cost competitive. This is where transition finance comes…

Coal Mid-Year Update 2025 Overview
Global coal demand grew by 1.5% in 2024, reaching an all-time high Global coal demand rose by 1.5% in 2024 to reach 8.79 billion tonnes (Bt), a new record. The growth was the slowest annual rate since the Covid-19 crisis in 2020 caused coal demand to decline. The post-Covid economic recovery and high natural gas prices have driven a sharp rise in global coal demand in recent years, but the growth has slowed year-on-year since 2021. Coal demand grew by 7.7% in 2021, 4.4% in 2022 and 2.3% in…

Global Energy Review 2026 Oil
Oil demand growth remained subdued in 2025 Oil demand increased in 2025 by 0.65 mb/d (million barrels per day) or 1.2 EJ, but this 0.7% rise marked a further slowdown from 2024’s already-muted 0.75 mb/d of growth. The increase in both years was in line with IEA projections. The 2025 increase fell well short of the 2010-19 average annual rise of 1.4 mb/d, offering further evidence of a structural deceleration in oil markets.This slowdown mainly reflected weaker growth in petrochemical feedstock use. Demand for naphtha, liquefied petroleum gas…

Brazil 2025 Executive summary
Brazil has positioned itself as a leader in the global energy transition. Its vast renewable energy resources, strong biofuels sector and ambitious climate commitments offer distinct advantages in the low-carbon economy. The country has introduced a comprehensive National Energy Transition Policy (PNTE) aimed at achieving net zero greenhouse gas (GHG) emissions by 2050, supported by the Energy Transition Plan (PLANTE) and the Energy Transition Forum (FONTE). In 2024, the country also launched the Low-Carbon Hydrogen Law, the Brazilian Greenhouse Gas Emissions Trading System Law, the Fuel of the Future Law and the Energy Transition Acceleration Program, further boosting momentum…

Multiple Benefits of Energy Efficiency for Business Turning the opportunity into reality
Across sectors, the evidence consistently shows that the value of energy efficiency extends far beyond energy savings, often matching or even exceeding them.A key challenge is that much of this value is not systematically captured in investment decisions. Business cases are often built on energy savings alone, overlooking gains in productivity, resource efficiency, product quality, brand reputation and workforce health. Reflecting these wider benefits can significantly strengthen investment cases and improve how efficiency projects compete for capital.This report draws on available evidence to highlight these broader benefits and why they matter in practice. The steps below show how…

Electricity Mid-Year Update 2025 Supply: Renewables grow the most, followed by gas and nuclear
As highlighted in our annual Electricity 2025 report, low-emissions energy sources are reaching new milestones globally in our forecast period. Renewables are poised to surpass coal-fired generation, depending on weather trends and economic developments, either as early as 2025 or in 2026. As a result, coal’s share in total generation is set to drop below 33% for the first time in the last 100 years.Solar PV and wind energy are key drivers of this trend, with their combined share in global electricity generation expected to rise from 15% in 2024 to 17% in 2025 and to above…
