Why Global Emissions Are Expected to Grow in 2022—and What Must Change
Despite years of warnings and pledges, global emissions are set for another increase in 2022 as fossil fuel demand outpaces progress on climate action.
After a brief pandemic-induced decline in 2020, global greenhouse gas emissions rebounded sharply in 2021 and are now forecast to grow further in 2022. This surge threatens to undermine international climate targets and highlights the urgent need for decisive policy actions, technological transformation, and behavioral changes. Below, we explore the drivers behind the projected increase, the sectors most responsible, the inadequate pace of global action, and what must change to prevent catastrophic heating of our planet.
Key Points
- Global emissions are likely to grow in 2022 due to increased fossil fuel consumption and slow progress on clean energy.
- Fossil fuels remain the dominant source of energy, especially as countries seek energy security amid ongoing geopolitical tensions.
- Current policy and pledges remain insufficient to meet agreed climate goals, risking a temperature rise well above 2°C by 2100.
- Systemic change in energy, transport, industry, and agriculture is needed to reverse emission trends.
After the Pandemic: Emissions Rebound and Grow
Global greenhouse gas emissions fell by about 6% in 2020, largely due to COVID-19 lockdowns that disrupted transport, industry, and daily life. However, this reduction was temporary. By 2021, emissions surged back—coal, oil, and gas demand returned as economies restarted and people resumed pre-pandemic behaviors.
- Coal bounce: Coal use in 2021 nearly matched pre-pandemic levels globally, with countries like China and India increasing consumption to meet growing energy demand.
- Oil and transport: Road travel and aviation rebounded as restrictions eased, pushing oil demand—and tailpipe emissions—upward.
- Natural gas: As a bridge fuel, natural gas has expanded rapidly, sometimes displacing coal but also contributing significant emissions.
Analysts expect that in 2022, emissions will not only return to pre-pandemic levels but could reach new highs—particularly if economic growth outpaces clean energy adoption and governments double down on domestic fossil fuel production for energy security.
The Drivers: Fossil Fuels, Economic Recovery, and Energy Security
Several converging factors are expected to drive the continuing growth in emissions during 2022:
- Energy insecurity: Geopolitical instability and supply chain issues (exacerbated, for example, by Russia’s war in Ukraine) have prompted many countries to prioritize short-term reliable energy over climate goals.
- Economic stimulus: COVID-19 recovery packages in many nations include support for infrastructure and energy. Much of this spending still flows towards carbon-heavy sectors like construction, manufacturing, and fossil energy.
- Prolonged coal reliance: Coal-fired power generation remains integral in Asia and some other regions, and temporary spikes in coal use have occurred even in nations with net-zero targets.
Despite years of climate summits and ambitious national targets, fossil fuels remain the backbone of the global energy system. In 2022, mounting concerns over price volatility and supply shortages have made it more difficult for governments to phase out coal and gas swiftly—the result: another year of emissions growth.

Sector Analysis: Where Emissions Are Rising Most
The increase in emissions is uneven across regions and sectors, but some key areas stand out:
| Sector | Main Sources | 2022 Trend |
|---|---|---|
| Energy | Coal, oil, natural gas | Significant growth in fossil electricity generation due to energy shortages; renewables unable to meet surging demand quickly |
| Transport | Cars, trucks, aviation | Rapid recovery to near pre-pandemic activity; aviation and road transport emissions increasing |
| Industry | Steel, cement, manufacturing | Expanded production is driving higher CO₂ outputs, particularly from resource-intensive manufacturing |
Transport emissions in several countries now exceed pre-pandemic levels as international air travel resumes and car use increases. In many regions, emissions from electricity and heating are no longer the largest share; instead, transport has become the leading source, a trend likely to continue as economies become more mobile.
Emissions Metrics: Per Capita, National, and Historical Perspectives
It’s crucial to understand that not all nations contribute equally to emissions growth, and different metrics highlight different aspects:
- Per capita emissions: In 2022, China’s per capita emissions matched those in the UK for the first time.
- National totals: China, the United States, India, and the EU account for over half of global emissions combined, driven mainly by energy demand.
- Historical responsibility: Developed nations have released much more CO₂ over past centuries, raising equity concerns in international climate negotiations.
These figures inform climate policy debates: should responsibility for emission cuts rest more on current heavy emitters or those historically responsible?
Why Paris Is at Risk: The Science of Overshoot
The centerpiece of global climate agreements, the Paris Agreement, aims to keep global temperature increase well below 2°C (preferably 1.5°C) above pre-industrial levels. Yet, current emissions pathways are far off track:
- Current pledges, even if fully enacted, likely result in >2°C warming by 2100.
- Delay costs: Every year of emissions growth makes future reductions harder and costlier, requiring radical decarbonization.
- Carbon budget shrinking: The total amount of CO₂ humanity can emit before crossing Paris thresholds is rapidly diminishing.
Scientists warn that continued annual emissions growth makes it increasingly impossible to stay below 1.5°C—or even 2°C—without dramatic acceleration in policy, technology, and behavior changes.
Feedbacks, Nonlinearities, and Tipping Points
Climate systems and human societies are deeply interconnected, producing complex feedbacks and risks of sudden shifts:
- Nonlinear feedbacks: Emissions growth can trigger climate tipping points—such as rapid ice melt, forest dieback, and methane release from permafrost—that further accelerate warming.
- Societal inertia: Social, political, and institutional factors may slow action, while economic interests tied to fossil fuels resist change.
- Public opinion: Shifts in perception and concern drive policy, but misinformation and fatigue can blunt momentum.
Recent research clusters future emissions outcomes into scenarios ranging from 1.8°C to 3.6°C of warming by 2100, depending on how quickly and effectively societies respond to emerging threats and opportunities.
The Role of Policy and Technology—and Why Current Action Is Not Enough
To reverse growth in emissions, leadership in policy and investment is essential across every sector, from industry to land use:
- Decarbonizing electricity: Investment in wind, solar, hydro, and grid upgrades must far outpace new fossil projects.
- Accelerating transport transformation: Electrification, public transit, and alternative fuels are key to curbing tailpipe emissions.
- Industry innovation: Low-carbon materials, closed-loop systems, and efficiency can dramatically cut manufacturing emissions.
- Agriculture and land: Reducing methane, reforestation, and sustainable farming practices have significant mitigation potential.
So far, government plans and investments have not matched the scale needed to achieve Paris targets. Gaps remain between announcements and actual implementation, and many nations lack binding policies or adequate funding for transition.
The Fossil Fuel Lock-In—And How to Break It
The fossil fuel system is entrenched by infrastructure, jobs, and policy. Breaking free requires overcoming key barriers:
- Stranded assets: Trillions of dollars are tied up in coal, oil, and gas operations; transitioning away risks economic and political backlash.
- Subsidies and market bias: Many economies still subsidize fossil fuels much more than clean energy, distorting incentives.
- Technology gaps: Some solutions—like renewable hydrogen or carbon capture—are promising but not yet cost-effective at scale.
Only coordinated action across government, business, and civil society can deliver the systemic change needed. This includes phasing out fossil subsidies, investing in clean technology, retraining workers, and aligning financial flows with climate goals.
The Importance of Equity, Justice, and International Cooperation
Climate change is a universal challenge, but the burdens and capacities to respond are not equally distributed:
- Developing nations: More vulnerable to climate impacts, often lack resources for rapid transition.
- Wealthier countries: Historically responsible for most emissions, better positioned to lead decarbonization and support those most affected.
- Climate finance obligations: Developed nations have pledged billions in support for developing countries, but delivery has lagged far behind commitments.
Failure to address these disparities undermines trust and the ability of the global community to move quickly and together on climate solutions.
What Must Change: Pathways to Stabilize the Climate
To prevent another year of record emissions and secure a livable future, decisive action is required in four areas:
- 1. Policy acceleration: Moving from pledges to laws, enforcement, and real investment in decarbonization.
- 2. Economic transformation: Reforming subsidies, increasing carbon prices, and mobilizing clean finance.
- 3. Technological innovation: Scaling up renewables, storage, electrification, and next-generation solutions.
- 4. Societal engagement: Building public support, inclusive transitions, and climate literacy to drive collective change.
Critically, decisions made in 2022 and soon after will shape emissions trajectories for decades. Delay today compounds risks—while ambitious action offers both economic and environmental reward.
Frequently Asked Questions (FAQ)
Why did emissions fall in 2020 and then rebound so quickly?
Emissions dropped primarily due to transport and industrial shutdowns during the COVID-19 pandemic. Once restrictions eased and economies reopened, fossil fuel demand quickly recovered, sending emissions back to or above previous levels.
Is it still possible to meet the Paris Agreement goals?
It remains technically possible, but time is running out. Every year of delay increases the challenge and requires more radical, costly changes in future years.
Which sectors are most responsible for emissions growth in 2022?
Energy generation (coal, oil, gas), transport (especially aviation and road vehicles), and heavy industry (steel, cement, manufacturing) are the biggest contributors.
What role do individual actions play compared to governments and industry?
Individual actions—diet, travel, energy use—matter, but systemic change driven by government policy and industry investment is essential to achieve emissions reductions at the necessary scale.
Does economic growth always mean more emissions?
No. Some countries have begun to decouple economic growth from carbon emissions, especially through investment in clean technology and efficiency. But globally, more growth still often means more emissions unless robust climate policies are in place.
Conclusion: Facing an Urgent Choice
The expectation that emissions will grow in 2022 is not inevitable—it is a policy choice shaped by today’s decisions. The path to averting dangerous climate change is clear, but it demands an end to fossil fuel expansion, vastly increased support for clean energy, and a collective global effort focused on justice and equity. Our future climate depends on what we do now.
