Global renewable energy reached a major turning point in 2025. For the first time in history, it generated more electricity than coal, marking a shift in how the world produces power.
Let’s take a closer look at the details and how this milestone impacts the clean energy transition landscape as well as carbon markets.
Clean Energy Hits Historic Milestone in Global Electricity Mix
According to energy think tank Ember, renewables’ share of global electricity overtook coal’s share in 2025. Renewables now supply more than a third of global power, while coal’s share has fallen below one‑third.

Ember notes that solar and wind together met about 99% of new global electricity demand growth in 2025. This helped push renewables ahead of coal despite rising energy use worldwide.
This milestone reflects years of investment in clean energy and signals a structural change in the global power system. It also shows that renewable technologies are now scaling fast enough to compete with traditional fossil fuels.

Solar Power Drives Record Growth in Clean Electricity
Solar energy led the global expansion in renewables. The Ember report stated,
“Record solar growth meant clean power sources grew fast enough to meet all new electricity demand in 2025, thereby preventing an increase in fossil generation. This was the first year since 2020 without an increase in electricity generation from fossil fuels and only the fifth year without a rise this century.”
The data shows that solar generation grew by about 636 terawatt‑hours (TWh) in 2025, the largest annual increase of any single electricity source ever. This surge made solar the main driver of new electricity supply.
Solar output increased by around 30% in 2025, reflecting rapid deployment and falling costs. It also played a key role in meeting rising demand.

Ember’s analysis indicates that solar alone met about 75% of the net increase in global electricity demand in 2025. Wind energy also contributed strongly, helping renewables meet almost all of the year’s additional demand.
The continued drop in solar costs has supported this growth. Over the past decade, solar module prices have fallen by more than 80%, making it one of the cheapest sources of new electricity in many markets.
Asia Powers the Shift: China and India Drive the Transition
The shift toward renewables has been driven largely by Asia’s biggest economies, per Ember data. China remains the largest contributor to global solar growth. It accounted for about 55% of the increase in solar generation in 2025, reflecting its large-scale investments in clean energy infrastructure.
The United States contributed around 14% of global solar growth, while India also expanded its renewable capacity significantly.
A key development in 2025 was the decline in fossil fuel generation in both China and India at the same time. This has not happened in many years.

Globally, coal generation dropped by 63 TWh in 2025, driven by reduced output in these major economies. This decline played a critical role in allowing renewables to overtake coal.
The transition in these countries has a global impact. Together, China and India account for a large share of global electricity demand and emissions.
In 2025, the two countries together represented roughly one‑fifth of global electricity demand and more than one‑fifth of global power‑sector CO₂ emissions, according to Ember’s annual electricity review and supporting analyses.
Emissions Peak? Clean Power Starts to Bend the Curve
Despite rising electricity demand, emissions from the power sector are beginning to stabilize. Global electricity demand increased by about 2.8% in 2025. However, power-sector emissions fell slightly, even with the higher demand.
According to Ember’s 2025 annual electricity review, power‑sector emissions fell slightly in 2025 despite a rise in global electricity demand. The analysis indicates that, without the growth of solar and wind, emissions from the power sector would have been about 236 MtCO₂ higher than they actually were.
This shows how renewable energy is helping offset emissions from growing energy use. The data further shows that the average kilowatt-hour of electricity produced globally resulted in 458 gCO₂e in 2025, about 2.7% less than 471 gCO₂e in 2024.
The International Energy Agency also projects a steady decline in carbon intensity. Global electricity emissions intensity is expected to fall from 445 grams of CO₂ per kilowatt-hour (gCO₂/kWh) in 2024 to about 400 gCO₂/kWh by 2027.

This represents an average annual reduction of 3.6%, highlighting gradual progress toward cleaner electricity systems.
The Grid Test: Can Power Systems Keep Up With Renewables?
The rapid growth of renewables brings new challenges for power systems. Solar and wind are variable sources, meaning their output depends on weather conditions.
By 2030, variable renewables are expected to supply nearly 30% of global electricity, roughly double current levels. This will require more flexible and resilient power grids.
Key solutions include:
- Expanding grid infrastructure,
- Increasing energy storage capacity, and
- Improving demand-side management.
Battery storage is playing a central role in this transition. Global battery deployment is growing quickly as costs fall.
Battery costs dropped by about 45% in 2025, to a record low of about $70 per kilowatt-hour. Meanwhile, installed storage capacity additions increased by 46% during the same period, reaching about 247 gigawatt-hours in 2025. These systems help store excess solar energy during the day and release it when demand rises.
Current battery capacity can already shift about 14% of solar generation from midday to other times of the day. This improves grid stability and reduces reliance on fossil fuel backup.
Corporate Action Supports Clean Energy Growth
Large companies are also helping drive renewable energy adoption. Microsoft has committed to using 100% renewable electricity for its operations and aims to become carbon negative by 2030. Google is investing heavily in solar and wind projects worldwide, including partnerships in Asia to support clean energy supply for data centers.

Corporate demand for renewable energy is growing as companies set net-zero targets and seek to reduce their carbon footprints. This trend supports further investment in renewable capacity and helps scale clean technologies.
Market Implications for Carbon Credits and Investment
The rise of renewables has important implications for carbon markets and clean energy investment. As renewable generation increases, the need for fossil fuel-based power declines. This can reduce emissions and affect demand for certain types of carbon credits.
At the same time, the transition creates new opportunities. Projects that support grid stability, energy storage, and renewable integration may generate additional carbon credits.
Investors are also shifting focus toward clean energy infrastructure. Renewable energy projects are becoming more competitive as costs fall and policy support strengthens.
The milestone of renewables overtaking coal provides strong evidence that the energy transition is accelerating.
A Turning Point for Global Energy
The fact that renewables have surpassed coal in global electricity generation marks a major turning point. It shows that clean energy is no longer a niche solution. Instead, it is becoming the foundation of the global power system.
Solar and wind are now growing fast enough to meet rising demand while reducing dependence on fossil fuels. Challenges remain, especially in grid integration and storage. However, continued investment and innovation are helping address these issues.
For policymakers, investors, and businesses, the message is clear: The global energy transition is moving from ambition to reality.
As renewable energy continues to expand, it will play a central role in reducing emissions, supporting economic growth, and building a more sustainable energy system.

Carbon Footprint
Industries with the biggest nature footprints and what their decarbonisation looks like
A corporate carbon footprint is never just an accounting figure. It maps onto real ecosystems. Before a product leaves the factory gate, something on the ground has already paid the cost. A forest has been converted. A river has been depleted. A patch of savannah that was once home to dozens of species now grows a single crop in every direction.

Apple, Amazon Lead 60+ Firms to Ease Global Carbon Reporting Rules
More than 60 global companies, including Apple, Amazon, BYD, Salesforce, Mars, and Schneider Electric, are pushing back against proposed changes to global emissions reporting rules. The group is calling for more flexibility under the Greenhouse Gas Protocol (GHG Protocol), the most widely used framework for measuring corporate carbon footprints.
The companies submitted a joint statement asking that new requirements, especially those affecting Scope 2 emissions, remain optional rather than mandatory. Their letter stated:
“To drive critical climate progress, it’s imperative that we get this revision right. We strongly urge the GHGP to improve upon the existing guidance, but not stymie critical electricity decarbonization investments by mandating a change that fundamentally threatens participation in this voluntary market, which acts as the linchpin in decarbonization across nearly all sectors of the economy. The revised guidance must encourage more clean energy procurement and enable more impactful corporate action, not unintentionally discourage it.”
The debate comes at a critical time. Corporate climate disclosures now influence trillions of dollars in capital flows, while stricter reporting rules are being introduced across major economies.
The Rulebook for Carbon: What the GHG Protocol Is and Why It’s Being Updated
The Greenhouse Gas Protocol is the world’s most widely used system for measuring corporate emissions. It is used by over 90% of companies that report greenhouse gas data globally, making it the foundation of most climate disclosures.
It divides emissions into three categories:
- Scope 1: Direct emissions from operations
- Scope 2: Emissions from purchased electricity
- Scope 3: Emissions across the value chain

The current Scope 2 rules were introduced in 2015, but energy markets have changed since then. Renewable energy has expanded, and companies now play a major role in funding clean power.
Corporate buyers have already supported more than 100 gigawatts (GW) of renewable energy capacity globally through voluntary purchases. This shows how influential the current system has been.
The GHG Protocol is now updating its rules to improve accuracy and transparency. The revision process includes input from more than 45 experts across industry, government, and academia, reflecting its global importance.
Scope 2 Shake-Up: The Battle Over Real-Time Carbon Tracking
The proposed update would shift how companies report electricity emissions. Instead of using flexible systems like renewable energy certificates (RECs), companies would need to match their electricity use with clean energy that is:
- Generated at the same time, and
- Located in the same grid region.
This is known as “24/7” or hourly or real-time matching. It aims to reflect the actual impact of electricity use on the grid. Companies, including Apple and Amazon, say this shift could create challenges.

According to industry feedback, stricter rules could raise energy costs and limit access to renewable energy in some regions. It can also slow corporate investment in new clean energy projects.
The concern is that many markets do not yet have enough renewable supply for real-time matching. Infrastructure for tracking hourly emissions is also still developing.
This creates a key tension. The new rules could improve accuracy and reduce greenwashing. But they may also make it harder for companies to scale clean energy quickly.
The outcome will shape how companies measure emissions, invest in renewables, and meet net-zero targets in the years ahead.
Why More Than 60 Companies Oppose the Changes
The companies argue that stricter rules could slow climate progress rather than accelerate it. Their main concern is cost and feasibility. Many regions still lack enough renewable energy to support real-time matching. For global companies, aligning energy use across different grids is complex.
In their joint statement, the group warned that mandatory changes could:
- Increase electricity prices,
- Reduce participation in voluntary clean energy markets, and
- Slow investment in renewable energy projects.
They argue that current market-based systems, such as RECs, have helped scale clean energy quickly over the past decade. Removing flexibility could weaken that momentum.
This reflects a broader tension between accuracy and scalability in climate reporting.
Big Tech Pushback: Apple and Amazon’s Climate Progress
Despite their push for flexibility, both companies have made measurable progress on emissions reduction.
Apple reports that it has reduced its total greenhouse gas emissions by more than 60% compared to 2015 levels, even as revenue grew significantly. The company is targeting carbon neutrality across its entire value chain by 2030. It also reported that supplier renewable energy use helped avoid over 26 million metric tons of CO₂ emissions in 2025 alone.

In addition, about 30% of materials used in Apple products in 2025 were recycled, showing a shift toward circular manufacturing.
Amazon has also set a net-zero target for 2040 under its Climate Pledge. The company is one of the world’s largest corporate buyers of renewable energy and continues to invest heavily in clean power, logistics electrification, and low-carbon infrastructure.

Both companies argue that flexible accounting frameworks have supported these investments at scale.
The Bigger Challenge: Scope 3 and Digital Emissions
The debate over Scope 2 reporting is only part of a larger issue. For most large companies, Scope 3 emissions account for more than 70% of total emissions. These include supply chains, product use, and outsourced services.
In the technology sector, emissions are rising due to:
- Data centers,
- Cloud computing, and
- Artificial intelligence workloads.
Global data centers already consume about 415–460 terawatt-hours (TWh) of electricity per year, equal to roughly 1.5%–2% of global power demand. This figure is expected to increase sharply. The International Energy Agency estimates that data center electricity demand could double by 2030, driven largely by AI.
This creates a major reporting challenge. Even with cleaner electricity, total emissions can rise as digital demand grows.
Climate Reporting Rules Are Tightening Globally
The pushback comes as climate disclosure requirements are expanding and becoming more standardized across major economies. What was once voluntary ESG reporting is steadily shifting toward mandatory, audit-ready climate transparency.
In the European Union, the Corporate Sustainability Reporting Directive (CSRD) is now active. It requires large companies and, later, listed SMEs, to share detailed sustainability data. This data must match the European Sustainability Reporting Standards (ESRS). This includes granular reporting on emissions across Scope 1, 2, and increasingly Scope 3 value chains.
In the United States, the Securities and Exchange Commission (SEC) aims for mandatory climate-related disclosures for public companies. This includes governance, risk exposure, and emissions reporting. However, some parts of the rule face legal and political scrutiny.
The United Kingdom has included climate disclosure through TCFD requirements. Now, it is moving toward ISSB-based global standards to make comparisons easier. Similarly, Canada is progressing with ISSB-aligned mandatory reporting frameworks for large public issuers.
In Asia, momentum is also accelerating. Japan is introducing the Sustainability Standards Board of Japan (SSBJ) rules that match ISSB standards. Meanwhile, China is tightening ESG disclosure rules for listed companies through updates from its securities regulators. Singapore has also mandated climate reporting for listed companies, with phased Scope 3 expansion.
A clear trend is forming across jurisdictions: climate disclosure is aligning with ISSB global standards. There’s a growing focus on assurance, comparability, and transparency in value-chain emissions.
This regulatory tightening raises the bar significantly for corporations. The challenge is clear. Companies must:
- Align with multiple evolving disclosure regimes,
- Ensure emissions data is verifiable and auditable, and
- Expand reporting across complex global supply chains.
Balancing operational growth with compliance is becoming increasingly complex as climate regulation converges and intensifies worldwide.
A Turning Point for Global Carbon Accounting
The outcome of this debate could shape global carbon accounting standards for years.
If stricter rules are adopted, emissions reporting will become more precise. This could improve transparency and reduce greenwashing risks. However, it may also increase compliance costs and limit flexibility.
If the proposed changes remain optional, companies may continue using current accounting methods. This could support faster clean energy investment, but may leave gaps in reporting accuracy.
The new rules could take effect as early as next year, making this a near-term decision for global companies.
The push by Apple, Amazon, and other companies highlights a key tension in climate strategy. On one side is the need for accurate, real-time emissions reporting. On the other is the need for flexible systems that support large-scale clean energy investment.
As digital infrastructure expands and energy demand rises, how emissions are measured will matter as much as how they are reduced. The next phase of climate action will depend not just on targets—but on the systems used to track them.

Mastercard Beats 2025 Emissions Targets as Revenue Rises 16%, Breaking the Growth vs Carbon Trade-Off
Mastercard says it has exceeded its 2025 emissions reduction targets while continuing to grow its global business. The company reduced emissions across its operations even as revenue increased strongly in 2025.
The update comes from Mastercard’s official sustainability and technology disclosure published in 2026. It confirms progress toward its long-term goal of net-zero emissions by 2040, covering its full value chain.
The results are important for the financial technology sector. Digital payments depend heavily on data centers and cloud systems, which are energy-intensive and linked to rising global emissions.
Breaking the Pattern: Emissions Fall While Revenue Rises
In 2025, Mastercard surpassed its interim climate targets compared with a 2016 baseline. The company reported a 44% reduction in Scope 1 and Scope 2 emissions, beating its target of 38%. It also achieved a 46% reduction in Scope 3 emissions, far exceeding its 20% target.
At the same time, Mastercard recorded 16% revenue growth in 2025. This shows that emissions reductions continued even as the business expanded. Mastercard Chief Sustainability Officer Ellen Jackowski and Senior Vice President of Data and Governance Adam Tenzer wrote:
“These results reflect a comprehensive approach built on renewable energy investment and procurement, supply chain engagement, and embedding environmental sustainability into everyday business decisions.”
The company also reported a 1% year-on-year decline in total emissions, marking the third consecutive year of emissions reduction. This is important because digital payment networks usually grow with higher computing demand.
Mastercard says this trend reflects improved efficiency across its operations, better infrastructure use, and increased reliance on cleaner energy sources.

The Hidden Footprint: Why Data Centers Drive Mastercard’s Emissions
A large share of Mastercard’s emissions comes from its digital infrastructure. According to the company’s sustainability report, data centers account for about 60% of Scope 1 and Scope 2 emissions. Technology-related goods and services make up roughly one-third of Scope 3 emissions.
This reflects how modern financial systems operate. Digital payments, fraud detection, and AI-based analytics require a large-scale computing infrastructure.
Global data centers already consume about 415–460 TWh of electricity per year, equal to roughly 1.5%–2% of global electricity demand. This number is expected to rise as AI usage expands.
Mastercard’s challenge is similar to that of other digital companies. Higher transaction volume usually leads to greater computing needs. This can raise emissions unless we improve efficiency.
To manage this, the company is focusing on renewable energy procurement, hardware consolidation, and more efficient software systems.
Carbon-Aware Technology Becomes Core to Operations
Mastercard is integrating sustainability directly into its technology systems rather than treating it as a separate reporting function. Since 2023, the company has developed a patent-pending system that assigns a Sustainability Score to its technology infrastructure. This system measures environmental impact in real time.
It tracks factors such as:
- Energy use in kilowatt-hours,
- Regional carbon intensity of electricity,
- Server utilization rates,
- Hardware lifecycle efficiency, and
- Data processing location.
This allows engineers to design systems with lower carbon impact.
The company also uses carbon-aware software design. This means computing workloads can be adjusted to reduce energy use when carbon intensity is high in certain regions.
This approach reflects a wider trend in the technology and financial sectors. More companies are now including carbon tracking in their main infrastructure choices. They no longer see it just as a reporting task.
Powering Payments: Mastercard’s Net-Zero Playbook
Mastercard has committed to reaching net-zero emissions by 2040, covering Scope 1, Scope 2, and Scope 3 emissions across its value chain. The target is aligned with science-based climate pathways and includes operations, suppliers, and technology infrastructure.
To achieve this, the company is focusing on four main areas.
-
Increasing renewable energy use in operations
Mastercard already powers its global operations with 100% renewable electricity. This covers offices and data centers in multiple regions.
The company has also achieved a 46% reduction in total Scope 1, 2, and 3 emissions compared to its 2016 baseline. It continues to use renewable energy purchasing to maintain this progress.
In 2024, Mastercard procured over 112,000 MWh of renewable electricity, supporting lower emissions from its global operations.
-
Improving energy efficiency in data centers
Data centers account for about 60% of Mastercard’s Scope 1 and 2 emissions. To reduce this, Mastercard is upgrading servers, cutting unused computing capacity, and improving workload efficiency. It also uses real-time monitoring to reduce energy waste.
These improvements helped keep operational emissions stable in 2024, even as computing demand increased. Efficiency gains combined with renewable energy use supported this outcome.
-
Working with suppliers to reduce emissions
Around 75%–76% of Mastercard’s total emissions come from its value chain. This includes cloud providers, technology partners, and hardware suppliers.
To address this, Mastercard works with suppliers to set emissions targets and improve reporting. More than 70% of its suppliers now have their own climate reduction goals.
-
Upgrading and consolidating hardware systems
Mastercard is reducing emissions by improving its hardware systems. It decommissions unused servers, consolidates infrastructure, and shifts to more efficient cloud platforms.
Technology goods and services account for about one-third of Scope 3 emissions. By reducing unnecessary hardware and extending equipment life, Mastercard lowers both energy use and manufacturing-related emissions while maintaining system performance.
Renewable energy procurement is central to its strategy. It’s crucial for powering data centers, as they account for most of their operational emissions.
Mastercard works with suppliers because a large part of emissions comes from the value chain. This includes technology manufacturing and cloud services. By 2025, the company exceeded several short-term climate goals. This shows early progress on its long-term net-zero path.

ESG Pressure Hits Fintech: The New Rules of Digital Finance
Mastercard’s results come during a period of rising ESG pressure across the financial sector. Banks, payment networks, and fintech companies must now disclose emissions. This is especially true for Scope 3 emissions, which cover supply chain and digital infrastructure impacts.
Several global trends are shaping the industry:
- Growing regulatory focus on climate disclosure,
- Rising investor demand for ESG transparency,
- Expansion of digital payments and cloud computing, and
- Increased energy use from AI and data processing.
Data centers are becoming a major focus area because they link financial services to energy consumption. In Mastercard’s case, they are the largest source of operational emissions.
At the same time, financial institutions are expected to align with net-zero targets between 2040 and 2050. This depends on regional regulations and climate frameworks. Mastercard’s early progress places it ahead of many peers in meeting short-term emissions goals.
Decoupling Growth From Emissions
One of the most important signals from Mastercard’s 2025 results is the separation of business growth from emissions.
The company achieved 16% revenue growth while reducing total emissions by 1% year-on-year. This marks a continued pattern of emissions decline alongside business expansion.
Mastercard attributes this to improved system efficiency, renewable energy use, and better infrastructure management. In simple terms, the company is processing more transactions without a matching rise in emissions.
This trend is important because digital payment systems normally scale with computing demand. Without efficiency gains, emissions would typically rise with business growth.
Looking ahead, demand will continue to grow. Global payments revenue is projected to reach around $3.1 trillion by 2028, according to McKinsey & Company, growing at close to 10% annually.

Global data center electricity demand might double by 2030. This rise is mainly due to AI workloads, says the International Energy Agency. Mastercard’s results show that tech upgrades can lower the carbon impact of digital finance. This is true even as global usage rises.
The Takeaway: Fintech’s Proof That Growth and Emissions Can Split
Mastercard’s 2025 sustainability performance shows measurable progress toward its net-zero goal. At the same time, major challenges remain. Data centers continue to be the largest emissions source, and global digital activity is still expanding rapidly due to AI and cloud computing.
Mastercard’s approach shows how financial technology companies are adapting. Sustainability is no longer a separate goal. It is becoming part of how digital systems are designed and operated.
The next test will be whether these efficiency gains can continue to outpace the rapid growth of global digital payments and AI-driven financial systems.
