Central Asia’s Carbon Problem Starts With How Much Energy Its Economy Wastes

Central Asia's decarbonization challenge is framed as a conflict between economic development and environmental protection, but research spanning more than two decades suggests the more decisive issue may lie elsewhere: how efficiently the region uses energy, how quickly it modernizes production, and whether global investment accelerates cleaner technologies or reinforces carbon-intensive growth.

The study, "Does Globalization Accelerate or Mitigate Greenhouse Gas Emissions? Evidence from Energy Transition and Technological Innovation in Central Asia," published in Economies, is authored by Sukhrob Kholmatov, Samariddin Makhmudov, Khulkar Zunnunova, Odil Olimjonov, Yuldoshboy Sobirov, Shokhrukhbek Sirojetdinov and Nigina Sharapova. It examines greenhouse-gas emission growth across Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan over 2000–2024, assessing the roles of globalization, energy intensity, renewable energy, technological innovation, economic growth and urbanization.

It concludes that energy intensity is the strongest and most consistent driver of rising emissions, while renewable energy and technological innovation are associated with lower emissions growth. The results challenge the idea that economic expansion itself is the main environmental problem and instead point toward the structure and efficiency of growth as the more important policy battleground.

Energy Waste Is the Region's Biggest Carbon Liability

The strongest relationship identified in the analysis concerns energy intensity, a measure of how much energy an economy consumes to generate economic output. Across the study's principal models, a one-unit increase in energy intensity is associated with roughly 1.93 to 1.97 percentage points higher greenhouse-gas emission growth, making inefficient energy use the most important positive association examined.

Parts of Central Asia still depend on aging industrial infrastructure, fossil-fuel-intensive production and comparatively inefficient energy systems. In practical terms, reducing emissions is therefore not only about changing where electricity comes from; it is also about reducing the amount of energy required to produce goods, heat buildings and operate industrial systems.

Governments do not necessarily have to choose between industrial growth and environmental improvement if productivity gains can reduce energy consumption per unit of output. Modern factories, upgraded electricity grids, better insulation, efficient heating systems and stricter performance standards could potentially deliver both economic and climate benefits.

Energy-efficiency investment may offer some of the region's highest-value climate interventions. The researchers specifically highlight industrial modernization, rehabilitation of aging infrastructure, energy-efficient technologies and stronger efficiency standards as priorities for reducing emissions growth.

Renewables and Innovation Can Change the Quality of Growth

Renewable electricity emerges as the second major component of the region's transition. Across the baseline models, a one-unit increase in renewable energy's share is associated with roughly 0.99 to 1.39 percentage points lower greenhouse-gas emission growth, reinforcing the argument that changing the energy mix matters alongside reducing energy consumption.

The regional picture, however, is far from uniform. Kyrgyzstan and Tajikistan rely heavily on hydropower, while Kazakhstan and Uzbekistan have been expanding wind and solar capacity alongside energy systems that remain substantially connected to fossil fuels. This means energy-transition strategies cannot simply be copied from one country to another; they have to reflect different resource bases, industrial structures and infrastructure constraints.

Technological innovation produces another significant result. Higher research and development expenditure is associated with lower emissions growth, with the study estimating a reduction of around 1.04 to 1.06 percentage points for a one-unit increase in R&D expenditure as a share of GDP. The authors link this relationship to cleaner production, technological upgrading and improved energy efficiency.

For developing and transition economies, the combination is important. Renewable infrastructure can lower the carbon content of energy, but innovation determines how effectively businesses and industries use that cleaner energy. Climate policy therefore becomes inseparable from industrial policy, research capacity, technology transfer and the ability of domestic firms to absorb and deploy modern production technologies.

Globalization Is a Climate Opportunity and a Carbon Risk

Central Asia's deeper integration into international trade, foreign investment and infrastructure networks can expand economic activity and fossil-fuel production, but it can also import cleaner technologies, financing and environmental standards. The environmental outcome depends on which of these forces dominates.

The study's main empirical discussion reports globalization as positively associated with emissions growth, arguing that production expansion, trade and energy demand can increase environmental pressure in economies still heavily exposed to fossil fuels. This interpretation suggests that global economic integration, without accompanying environmental safeguards, can reinforce carbon-intensive development rather than automatically modernizing it.

However, the paper also presents a more complex distributional picture. Its quantile analysis indicates that globalization's effect varies across different parts of the emissions-growth distribution, while later sections describe stronger environmental benefits under some conditions. This suggests that globalization should not be treated as inherently polluting or inherently green; its impact is conditioned by investment quality, domestic regulation, technology diffusion and the sectors receiving foreign capital.

This is crucial for international development finance and the Belt and Road Initiative. Foreign investment in renewable energy, efficient transport, grids and low-carbon industry can accelerate the transition, while financing fossil-fuel infrastructure or energy-intensive production can lock emissions in for decades. The policy challenge is therefore not reducing globalization, but changing the environmental composition of globalization.

The study itself contains an inconsistency that deserves caution: some sections describe globalization as increasing emissions while others characterize its baseline relationship as negative. It does not invalidate the broader finding that its environmental effects are heterogeneous, but it does mean policymakers should avoid treating the paper as providing a single definitive estimate of globalization's climate impact.

Central Asia Needs a Modernization Strategy, Not a Growth Slowdown

Economic growth shows a weak and unstable relationship with emissions: two estimation methods indicate a modest negative association, while another finds no statistically significant effect. The evidence suggests that economic expansion does not necessarily translate proportionately into higher emissions.

Urbanization also produces a counterintuitive result. In the baseline estimates, higher urbanization is associated with slower emissions growth, potentially reflecting more efficient infrastructure, economies of scale and cleaner energy access. But because the study measures the growth rate of emissions rather than total emissions, this finding should not be interpreted as proof that urbanization reduces overall greenhouse-gas volumes.

The quantile analysis further shows that urbanization can become more environmentally damaging at higher points of the emissions-growth distribution. This underlines the importance of how cities are built: compact development, efficient public transport, cleaner heating, energy-efficient buildings and modern utility networks can determine whether urbanization moderates or intensifies environmental pressure.

There are important limitations. The study relies on national-level data, which can conceal large differences within countries, and it does not explicitly incorporate institutional quality, environmental regulation, energy pricing or financial development. Its econometric design identifies statistically robust associations rather than proving causal relationships.

Future research should therefore test these relationships using larger regional datasets, country-specific analysis and alternative emissions measures. The authors also point toward examining governance, green finance, digitalization, environmental policy and nonlinear effects to better understand why similar investments can produce different environmental outcomes across developing economies.
