GLOBAL INSIGHTS: LEADING THE CHANGE
Decarbonisation Costs: The Debate on Transitioning to a Zero-Emissions Economy in 2024
The global debate over the cost of decarbonising the world economy has taken center stage, with estimates suggesting that the transition to a zero-emissions future could range from $3 to $12 trillion annually. However, many experts argue that these projections are exaggerated. Some analysts believe the real cost could be less than $1 trillion per year—less than 1% of global GDP—if overestimates based on unrealistic growth rates and outdated assumptions about technology costs are corrected.
In 2024 alone, $3 trillion was invested in energy globally, with clean energy investments nearly doubling those in fossil fuels. Solar power emerged as the leader, attracting $500 billion in investments. This growth highlights the rapid acceleration of the clean energy sector.
Temperature projections reveal both progress and challenges. Optimistic scenarios suggest that current policies could limit global warming to 2.4–2.6°C by 2050. However, the Paris Agreement’s ambitious goal of capping warming at 1.5°C is now widely considered unattainable.
The challenges are particularly acute in developing countries, where higher financing costs hinder investments in clean energy, despite these regions being more vulnerable to the impacts of climate change.
This debate underscores the urgency of action and the importance of pursuing realistic, equitable solutions to ensure a sustainable and inclusive energy transition.

Key Insights on Climate Tech Investment Trends in 2024
A recent report by PwC, titled “State of Climate Tech 2024” reveals significant shifts in global investment trends within the climate technology sector.
Global funding for climate tech saw a sharp 29% drop, falling from $79 billion to $56 billion over 2024. This marks the lowest investment levels since 2019, signaling a challenging environment for climate-focused innovation. The energy sector emerged as a bright spot, capturing nearly 35% of total climate tech funding in 2024, up from 30% the previous year. However, other critical areas like industrials, agriculture, and urban development continue to struggle with disproportionately low funding, despite their significant contributions to global emissions. Artificial intelligence is carving out a growing niche in the climate tech landscape. AI-focused startups raised $6 billion in the first three quarters of 2024, surpassing the $5 billion total for 2023. Key applications include autonomous vehicles, smart agriculture, energy management, and intelligent home solutions.
Large corporations remain a vital force in the climate tech ecosystem, participating in around a quarter of all funding deals. Their involvement, especially in scaling mid- and late-stage startups, is helping to bridge investment gaps in underfunded but high-emission sectors like industrials and the built environment.

Energy Transition Challenges
The energy transition presents substantial challenges rooted in the complex physical realities of transforming a system optimized over centuries. Currently, only about 10% of the required deployment of low-emissions technologies for 2050 has been achieved. The transition faces significant barriers across seven interlinked domains—power, mobility, industry, buildings, raw materials, hydrogen and energy carriers, and carbon and energy reduction. Addressing these issues demands systemic innovation and extensive infrastructure development.
A critical obstacle is the sheer scale of transformation required. Low-emissions assets, including billions of electric vehicles and heat pumps, alongside substantial increases in renewable energy generation, must be deployed rapidly. Yet, the most demanding challenges arise where low-emissions technologies either lack comparable performance to fossil-fuel-based systems or require substantial infrastructure to become viable. Examples include integrating renewable variability into power grids, decarbonizing heavy industries like steel and cement, and developing scalable hydrogen solutions.

Hydrogen for Decarbonisation
The green hydrogen sector, once hyped as a cornerstone for a carbon-free future, is now facing significant challenges due to higher-than-expected costs and stalled projects. A BloombergNEF report reveals that green hydrogen, produced via electrolysis powered by renewables, will remain costly, with 2050 price estimates tripling from earlier forecasts, ranging from $1.60 to $5.09 per kilogram. This contrasts sharply with the $1.11 to $2.35 per kilogram cost of conventional “gray” hydrogen derived from natural gas. The US has seen billions of dollars in projects delayed due to unresolved tax credit rules, while Europe struggles with bureaucratic delays in defining "green hydrogen." Only China and India are projected to achieve cost parity with gray hydrogen by 2040.
Globally, several green hydrogen projects have been abandoned, and hiring in the sector has slowed. Clean hydrogen production is expected to triple this year but will still meet just 1% of global demand, with most hydrogen continuing to be produced using fossil fuels. Analysts describe the current phase as a necessary "reality check," with the industry shifting focus from overpromised growth to practical, scalable solutions.

Nuclear Power in Decarbonisation
The World Nuclear Performance Report 2024 highlights the resurgence of nuclear energy as a critical player in the global clean energy transition. In 2023, nuclear reactors worldwide generated 2602 TWh of electricity, an increase of 58 TWh compared to the previous year. Nuclear energy avoided 2.1 billion tonnes of CO₂ emissions in 2023, exceeding the annual emissions of nearly every country except China, India, and the United States.
The reliability of nuclear energy remains unmatched. The average global capacity factor for nuclear reactors reached 81.5% in 2023, marking over two decades of consistent performance above 80%. Notably, older reactors, especially those operating for more than 45 years, continue to outperform newer units, demonstrating that age does not diminish efficiency or reliability. Currently, 64 reactors are under construction globally, with Asia leading this effort.
Several case studies underline nuclear energy's adaptability and resilience. In the United States, the Palisades nuclear plant in Michigan is being brought back online by Holtec with $1.5 billion in federal funding, creating over 1600 jobs in the process. South Korea is extending the lifespans of 10 reactors, reinforcing its energy security and carbon neutrality objectives. In Czechia, the Dukovany plant achieved a 2.3% increase in power output without additional fuel or emissions, underscoring the potential for efficiency upgrades in existing facilities.
China remains at the forefront of nuclear development, with 30 reactors under construction. Beyond electricity generation, China is innovating in other applications, such as supplying industrial steam and residential heating using nuclear energy. These projects illustrate the versatility of nuclear power in addressing broader energy needs.
As global energy demand continues to rise, nuclear energy is increasingly recognized as a vital solution for delivering clean, reliable, and affordable power. However, achieving ambitious goals like tripling capacity by 2050 will require both the extension of existing reactors' lifespans and a significant acceleration in new reactor construction.

Global Decarbonization at a Crossroads: Net Zero Economy Index 2024 Key Insights
Global decarbonization efforts are facing a critical juncture, as outlined in the Net Zero Economy Index 2024. The report reveals that global carbon intensity dropped by a mere 1.02% in 2023, marking the lowest reduction in over a decade. To stay on track with the 1.5°C climate target, an unprecedented annual decarbonization rate of 20.4% is required—far exceeding the current pace.
Fossil fuels continue to dominate the energy landscape, with consumption rising by 1.5% in 2023 despite record growth in renewables, which accounted for only 19% of global energy use. Simultaneously, energy demand surged by 2.02%, driven by economic recovery, population growth, and industrialization, outpacing the adoption of renewables. However, renewable energy showed significant momentum, with global capacity growing by 14% to reach 3,870 GW, led by solar and wind energy. Projections suggest that renewable capacity will surpass coal by 2025.
In developed nations (G7), carbon intensity fell by 5.31%, thanks to energy efficiency measures and robust policy initiatives. Countries like France and Italy achieved notable reductions in fossil fuel dependence, but overall progress remains insufficient to meet Paris Agreement targets. Emerging economies (E7), on the other hand, faced increased challenges. Their carbon intensity rose slightly by 0.04% as they struggled with higher dependence on fossil fuels. For example, China saw a 4.7% increase in emissions, and India faced difficulties in balancing rapid economic growth with renewable energy adoption. The Asia-Pacific region showed mixed results, with China accounting for 60% of global renewable capacity additions in 2023, while weather-induced hydropower shortfalls in India and China underscored vulnerabilities in energy security.
Several critical challenges impede progress toward net zero. Macroeconomic pressures, including inflation, geopolitical tensions, and supply chain disruptions, have slowed investments in renewables and energy efficiency. Developing nations face disparities in their capacity to transition from fossil fuels, compounded by a lack of resources and international support. Additionally, there is an energy intensity gap: G7 countries achieved a 3.53% improvement in energy efficiency, while emerging economies showed negligible progress.
The report calls for urgent action from global leaders to accelerate decarbonization efforts. Key priorities include expanding renewable energy capacity, doubling energy efficiency improvements by 2030, and fostering public-private partnerships to drive innovation in energy systems. Scaling up international financial commitments is essential to support developing nations in achieving a just transition.
