On Tuesday 28 December 2021, Luxembourg's national statistics office, Statec, published an up-to-date dashboard relating to climate change indicators.

This shows that, in 2019, carbon dioxide (CO2) emissions from the household sector were of the same order of magnitude as those from the Luxembourg industrial sector, with CO2 emissions per capita in this sector decreasing significantly since 2010. 

In a 10-year timespan, total renewable energy consumption increased from 1,284 GWh in 2010 to 2,445 GWh in 2019 (an increase of 90%). 

In 2021, a carbon tax of €20 / ton of CO2 was implemented on all fossil fuels. 

For residential use, CO2 emissions per capita (also termed as household carbon intensity) has decreased (housing and transport included) since 2010:
- 2010: 3.5 tons of CO2
- 2015: 3.0 tons of CO2
- 2019: 2.5 tons of CO2

In 2019, household CO2 emissions were split as follows: central heating (60%); transport (38%); other (2%).

According to MeteoLux, precipitation (rainfall) in 2020 was 12% lower than the normal for the years 1981-2010. In 2020, there were 16 “hot days”, i.e. 12 more than the normal for the years 1981-2010. 

And according to the ACA, €125 million was paid by insurance companies for the floods of July 2021.
