Global Carbon Emissions Fall To 10% Of 2010 Levels.

Can Global Carbon Emissions Decline To 10% Of The 2010 Level By 2035?

Could global carbon emissions decline to one tenth (i.e., approximately 3.1 billion tons) of the 2010 level by 2035, representing a near-complete decarbonization of the energy system? This target requires a transformation far beyond even the IEA’s most ambitious net zero scenarios. Given current progress rates and technological investments, achieving this level by 2035 is highly unlikely (18%).

Why Is It So Difficult?

Such a decline would necessitate a fundamental shift encompassing not just electricity generation but also the entire industrial sector (steel, cement, chemicals) and transportation sectors (road, air, maritime) - all requiring near-complete cessation of fossil fuel use. This necessitates the deployment of carbon capture and storage (CCS) technologies alongside radical improvements in energy efficiency. Furthermore, rising energy demand from developing countries would complicate this goal even further.

Current Status and Projections

As of 2023, global emissions stand at approximately 37.4 billion tons. The 2010 level was around 30.6 billion tons - meaning the target represents more than 90% reduction from current levels. The IEA’s 2050 net zero scenario still projects emissions to be around 15-17 billion tons in 2035, requiring a decline five times faster than even its most optimistic official scenarios.

Technological and Economic Barriers

The current capacity of carbon removal technologies (DAC, BECCS) is below 2 billion tons per year, and their costs are substantial. While the rate of renewable energy installations is increasing, prematurely retiring existing fossil fuel infrastructure (coal-fired power plants, gas facilities) would result in significant economic losses by 2035. Moreover, global energy demand is expected to be 30-40% higher than in 2010 by 2035 - requiring simultaneous reduction of supply and decarbonization of demand.

Lack of Policy and International Cooperation

Current Nationally Determined Contributions (NDCs) predict only an 80% reduction in emissions compared to the 2010 level by 2035. Achieving this target requires radical policy changes, including globally binding carbon pricing, technology transfer, and the removal of fossil fuel subsidies - something currently impossible given geopolitical tensions and economic interest conflicts by 2035.

Conclusion: Why An 18% Probability?

The probability is assessed at 18% because it sits between “barely possible” and “highly unlikely.” However, if a sudden technological breakthrough occurs within the next 10 years - for example, cheap and efficient nuclear fusion or massive scaling of negative emission technologies - this possibility could increase. Nevertheless, given current trends and policy stability, this target appears distant and should be viewed more as an ‘emergency scenario’ rather than a realistic goal by 2035.

Frequently Asked Questions

Why Is Declining To 10% Of The 2010 Level So Critical?

This level represents near-complete decarbonization in energy, industry, and transportation. Reducing emissions from approximately 30.6 billion tons (the 2010 level) to 3.1 billion tons would require a significant reduction in fossil fuel use and widespread deployment of carbon removal technologies - fundamentally restructuring the current economic system.

Is The IEA’s Net Zero Scenario Close To This Target?

No. The IEA’s 2050 net zero scenario projects emissions to be around 15-17 billion tons in 2035, requiring a decline approximately five times faster than even its most ambitious scenario. Therefore, this target is far beyond the limits considered ‘possible’ by official institutions.

Which Technological Developments Could Increase This Probability?

Unexpected breakthroughs such as widespread, affordable carbon capture (DAC), advanced energy storage, commercialization of nuclear fusion, or massive scaling of energy efficiency innovations could increase the probability. However, these technologies are unlikely to be deployed at a global scale within 2035 given current R&D rates.
