The transition to a net zero economy represents both the greatest challenge and opportunity of our time. As global temperatures continue to rise, businesses, governments, and investors are increasingly recognising that ambitious climate action is not only an environmental imperative but also a powerful economic driver.
With climate impacts and stakeholder pressure both intensifying, the focus has decisively shifted from setting targets to delivering measurable results. Organisations are now embedding sustainability into their core operations and strategies, recognising that those who can effectively translate ambition into action gain a competitive advantage in rapidly evolving markets.
This comprehensive guide examines the current state of net zero commitments, green growth trends, and the innovative companies leading the transition to a sustainable future. For deeper insights into the tech sector’s specific journey to net zero, including case studies and practical guidance, see The Tech Zero Report.
What Is Net Zero?
Defining the Concept
Net zero refers to the balance between the amount of greenhouse gases (GHGs) produced and the amount removed from the atmosphere. At its core, achieving net zero means reducing emissions as much as possible, then removing an equivalent amount of any remaining emissions that cannot be eliminated. Unlike carbon neutrality, which often relies heavily on offsetting, net zero requires fundamental changes to business models and operations to achieve deep emissions reductions.
The concept has become the north star for climate action globally, with the Intergovernmental Panel on Climate Change (IPCC) identifying net zero CO₂ emissions by 2050 as necessary to limit global warming to 1.5°C above pre-industrial levels (IPCC, 2023).
Carbon Neutrality vs. Net Zero vs. Carbon Negative: Understanding the Difference
While often used interchangeably, these terms represent distinct approaches to climate action:

The Path to Net Zero
The journey to net zero typically follows several key stages:
Measurement: Establishing baseline emissions across Scopes 1, 2, and 3
Target-setting: Creating science-based reduction targets aligned with 1.5°C pathways
Reduction: Implementing strategies to dramatically cut emissions across operations
Transformation: Redesigning business models, products, and services
Removal: Investing in high-quality carbon removal for unavoidable emissions
Reporting: Providing transparent, verified updates on progress
This structured approach enables organisations to systematically address their climate impact while building the operational resilience needed in a carbon-constrained world.
Global Net Zero Targets by Country
The landscape of national climate commitments has evolved rapidly since the 2015 Paris Agreement, with a growing number of countries establishing legally binding net zero targets. As of early 2025, 153 countries representing over 90% of global GDP have now announced or are considering net zero targets (Energy & Climate Intelligence Unit, 2024).

Implementation Gaps and Progress Indicators
While commitments are important, implementation determines impact. Analysis from Climate Action Tracker (2024) shows significant gaps between pledges and policies. Even with full implementation of current policies, the world is on track for 2.7°C of warming by 2100 – well above the Paris Agreement goals.
Key implementation challenges include:
Policy alignment: Ensuring that economic, energy, and industrial policies support climate goals
Infrastructure transformation: Rebuilding energy systems, transportation networks, and buildings
Finance mobilisation: Securing sufficient investment for low-carbon transitions
Just transition: Managing economic impacts on communities dependent on fossil fuels
International cooperation: Coordinating action across borders, particularly for supply chains
Countries leading in implementation have established detailed sector-by-sector transition plans, robust carbon pricing mechanisms, and regular progress reviews. The UK’s Carbon Budget system, which sets legally binding 5-year emissions caps, exemplifies a structured approach to implementation.
Top Green Growth Stats (2025)
The transition to a net zero economy is creating unprecedented economic opportunities. What began as a niche environmental concern has evolved into a mainstream economic transformation, with green sectors now outpacing growth in conventional industries.
Economic Scale and Growth Projections
- The global green economy now represents approximately $4.5 trillion or about 5% of global GDP, with projections suggesting growth to 10-15% of global GDP by 2030 (BloombergNEF, 2024)
- Clean energy investments reached $1.8 trillion in 2024, exceeding fossil fuel investments for the third consecutive year (International Energy Agency, 2025)
- Green jobs are growing at 8% annually compared to 2% for traditional sectors, with over 15 million people now employed in renewable energy alone (International Renewable Energy Agency, 2024)
Carbon Pricing Adoption
Carbon pricing mechanisms – either through carbon taxes or emissions trading systems – continue to expand globally:
- As of early 2025, 71 carbon pricing initiatives are now implemented worldwide, covering approximately 23% of global emissions (World Bank Carbon Pricing Dashboard, 2025)
- The average carbon price in developed economies reached $35/tonne in 2024, though this remains below the $75-100/tonne range economists estimate is needed to drive transformation (OECD, 2024)
- The EU Emissions Trading System (ETS) price reached €80/tonne in 2024, creating strong incentives for industrial decarbonisation
- Border carbon adjustment mechanisms, pioneered by the EU, are driving global convergence in carbon pricing approaches
Investment Flows and Green Finance
Green finance has moved from niche to mainstream, with significant implications for capital allocation:
- Sustainable investing assets under management reached $53 trillion globally in 2024, representing more than 35% of professionally managed assets (Global Sustainable Investment Alliance, 2024)
- Green bond issuance hit a record $1.2 trillion in 2024, with corporate issuers leading growth (Climate Bonds Initiative, 2025)
- Climate tech venture funding reached $70 billion in 2024, with particular growth in hard-to-abate sectors (PwC State of Climate Tech, 2025)
- Financial institutions with over $130 trillion in assets have now committed to net zero targets through the Glasgow Financial Alliance for Net Zero
Who Emits the Most?
Understanding emissions profiles at national, sectoral, and corporate levels is essential for targeting climate action effectively.
Current Emissions by Country
The distribution of carbon emissions remains highly uneven, with just 20 countries responsible for approximately 80% of global greenhouse gas emissions.

Source: Global Carbon Project (2024)
Historical Responsibility for Climate Change
Current emissions tell only part of the story. Historical emissions – the accumulated emissions since the start of industrialisation – more closely correlate with responsibility for climate change given the long-lived nature of greenhouse gases.
Carbon Brief’s analysis of cumulative CO₂ emissions from 1850-2023 shows that:
- The United States has contributed approximately 20% of the global total
- China is responsible for around 11%
- Russia 7%, Brazil 5%, and Indonesia 4%
- European nations including Germany (4%) and the UK (3%) also feature prominently
This historical perspective is central to international climate negotiations and the principle of “common but differentiated responsibilities” enshrined in UN climate agreements.
Per Capita vs. Total Emissions
When considering emissions on a per person basis, the picture changes dramatically:
Top Per Capita Emitters (2024, tonnes CO₂e per person):
Qatar: 37.0
Kuwait: 25.3
United Arab Emirates: 23.9
Australia: 22.5
United States: 15.3
Canada: 15.1
Saudi Arabia: 15.0
Kazakhstan: 14.6
South Korea: 13.9
Russia: 12.4
By comparison, the global average is approximately 6.3 tonnes per person, with India at 2.7 tonnes and most African nations below 2 tonnes per person.
Sectoral Emissions Distribution
Understanding emissions by sector helps identify priority areas for decarbonisation:
- Energy (electricity and heat): 31%
- Industry: 24%
- Transportation: 15%
- Agriculture: 12%
- Buildings: 8%
- Land use change and forestry: 7%
- Waste: 3%
Source: Climate Watch, World Resources Institute (2024)
Within these broad categories, specific high-impact activities include:
- Coal-fired power generation
- Steel and cement production
- Livestock and rice cultivation
- Deforestation
- Aviation and shipping
The Technology Sector’s Growing Emissions Profile
According to The Tech Zero Report, the technology industry, while historically representing a smaller share of global emissions, is experiencing rapid growth in its carbon footprint. The tech industry currently accounts for 3-4% of global carbon emissions, with this figure rising due to the exponential growth in data center construction and AI workloads.
The data reveals concerning trends among major tech companies:
- Microsoft’s greenhouse gas emissions have grown by 29% since 2020 due to the construction of data centers designed to support AI workloads
- Google’s greenhouse gas emissions in 2023 were 48% higher than in 2019, attributed to data center energy consumption and supply chain impacts
- According to some estimates, actual data center emissions could be around 662% higher than what Big Tech companies report
However, the tech sector also demonstrates significant potential for emissions reduction. By 2050, digital technologies alone – including AI, cloud computing, and IoT – have the potential to cut global emissions from the highest-emitting sectors by 20%.
