Union of Concerned Scientists

Union of Concerned Scientists (UCS), based in the US and operating in the "Other services (93)" industry, has reported Scope 3 emissions for business travel and employee commute between 2009 and 2020.

In 2020, UCS reported approximately 828,000 kg CO2e in total emissions, primarily from Scope 3, including about 157,000 kg CO2e from business travel and approximately 70,000 kg CO2e from employee commute. This represents a reduction from 2019, when total emissions were approximately 1,218,000 kg CO2e, with Scope 3 business travel accounting for about 388,000 kg CO2e and employee commute for approximately 140,000 kg CO2e.

Prior to 2020, the organisation has disclosed Scope 1 and Scope 2 emissions, alongside Scope 3. In 2014, total emissions were approximately 1,025,000 kg CO2e, comprising about 289,000 kg CO2e from Scope 1 stationary combustion, approximately 203,000 kg CO2e from Scope 2 purchased electricity, and Scope 3 emissions including about 271,000 kg CO2e from business travel and 141,000 kg CO2e from employee commute. Emissions in 2013 were approximately 922,000 kg CO2e, with Scope 1 stationary combustion at about 253,000 kg CO2e, Scope 2 purchased electricity at approximately 188,000 kg CO2e, and Scope 3 business travel and employee commute at about 243,000 kg CO2e and 104,000 kg CO2e respectively. In 2012, total emissions were approximately 946,000 kg CO2e, with Scope 1 stationary combustion at about 246,000 kg CO2e, Scope 2 purchased electricity at approximately 200,000 kg CO2e, and Scope 3 business travel and employee commute at about 287,000 kg CO2e and 138,000 kg CO2e respectively.

UCS has outlined climate commitments related to reducing global warming emissions. One such commitment, referencing the California Low Carbon Fuel Standard, aimed for fuels used in the state to have 10 percent lower global warming emissions per unit of energy by 2020 compared to 2010 levels (Scope 1 intensity target). Additionally, UCS highlights the need for very deep cuts to emissions from the power sector by 2050 to limit the worst consequences of climate change, indicating long-term net-zero ambitions for Scope 1 and Scope 2 emissions.
