Based on the provisions of Act XLIV of 2020 on climate protection, the Hungarian government undertook the following actions:

• Hungary will reduce its greenhouse gas emissions by at least 40% by 2030 compared to 1990.
• After 2030, if final energy use in Hungary increases above 2005 levels, the increase will be met exclusively from carbon-neutral energy sources.
• Hungary aims to achieve a share of renewable energy sources in gross final energy consumption of at least 21% by 2030.
• Hungary will reach full climate neutrality by 2050, i.e., the remaining domestic emissions and removals of greenhouse gases will be in balance by 2050.

Despite the above, there is currently no Hungarian legislation in place to reduce CO2 emissions from buildings.
