Czech Republic Sectors

What is Czech Republicʼs pathway to limit global warming to 1.5°C?

How to citeLast update: February 2022

Power sector in 2030

In 2019, the power sector accounted for 29% of total greenhouse gas emissions.4 Due to its large share of overall emissions, a rapid decarbonisation of this sector is essential for Czechia to meet its emissions reduction targets.

According to 1.5°C compatible scenarios, the emissions intensity of the Czech power sector should decrease from 420 gCO₂/kWh in 2019 to 40-50 gCO₂/kWh by 2030. This can be achieved through a rapid phasing out of coal and increasing the share of renewables in the sector to 49-61% by this date. Considering Czechia’s current target of a 17% share of renewables in electricity by 2030, the government is a long way off bringing the power sector in line with a 1.5°C trajectory.

Towards a fully decarbonised power sector

1.5°C compatible scenarios indicate that coal needs to be phased out by 2029 and fossil gas before 2040 to ensure a totally decarbonised power sector by this date. Decarbonisation could be achieved by a rapid uptake of renewables in power generation. However, the government’s lack of support for renewables, as well as its plan to increase the share of fossil gas, means that decarbonisation will not be achieved under planned policies.2

Demand shifting towards the power sector

The 1.5°C compatible pathways analysed here tend to show a strong increase in power generation and installed capacities across time compared with a current policy scenario. This is because end-use sectors (such as transport, buildings or industry) are increasingly electrified under 1.5°C compatible pathways, shifting energy demand to the power sector. Globally, the “high energy demand” entails a particularly high degree of renewable energy-based electrification across the various sectors, and sees a considerable increase in renewable energy capacities over time. See the power section for capacities deployment under the various models.

Czech Republicʼs renewable electricity investments

Billion USD / yr


Yearly investment requirements in renewable energy

Across the set of 1.5°C pathways that we have analysed, annual investments in renewable energy excluding BECCS increase in Czech Republic to be on the order of USD 1 to 11 billion by 2030 and 1 to 13 billion by 2040 depending on the scenario considered. The ‘high energy demand, low CDR reliance’ pathway shows a particularly high increase in renewable capacity investments, which could be driven by an increase of electrification of end-use sectors and/or growing energy demand and expansion of electricity access. Other modelled pathways have relatively lower investments in renewables and rely to varying degrees on other technologies and measures such as energy efficiency and negative emissions technologies, of which the later can require high up-front investments.
