LONDON (Reuters) – Investors managing around $20 trillion in assets on Tuesday called on the heaviest corporate emitters of greenhouse gases to set science-based targets on the way to net zero carbon emissions by mid-century.
AXA Group and Nikko Asset Management Co are among 137 investors urging 1,800 companies responsible for a quarter of global emissions to act, coordinated by non-profit group CDP.
While more companies are pledging their support for the 2015 Paris agreement on climate change, aiming to be carbon neutral by 2050, not all have been clear about how they will get there.
To help limit global warming to no more than 1.5 degrees Celsius above pre-industrial norms by 2050, companies need to set out their pathway to net zero and ensure it is consistent with the science and independently verified, the investors said.
“Climate change presents material risks to investments, and companies that are failing to
Scientists affiliated with leading research institutions across the U.S. state in a letter published Monday in the journal Science that researchers across disciplines must converge to deliver clear public health guidance about how SARS-CoV-2 is spread in the air.
The researchers write in the open letter that the scientific community must clarify the terminology used related to aerosols and droplets, and employ a more modern size threshold, rather than the existing one based on 1930s-era work. Authors include experts from the University of California San Diego, University of Maryland, Virginia Tech, and others.
Public health officials should make a clear distinction between droplets ejected by coughing or sneezing — which have inspired the social distancing mantra of six feet of separation between people — and aerosols that can carry the virus for much greater distances. Viruses in aerosols smaller than 100 microns can remain airborne in a confined space for
MADRID — Groups representing more than 170,000 health workers are urging Spanish politicians to base their response to the pandemic on scientific grounds rather than politics.
A 10-point manifesto by 55 scientific societies published Sunday in all the major newspapers said “decisions must be based on the best available scientific evidence, completely detached from the continuous political confrontation.”
The campaign comes after a dispute between the left-wing national government and the conservative regional authorities of the Madrid region led to weeks of back and forth before partially locking down the Spanish capital late Friday amid a surge of infections.
The manifesto also calls for less red-tape in adopting measures against virus outbreaks, for authorities in Spain’s 19 regions to abide by a set of national scientific standards that would dictate the response, and calls for stopping interference in medical decisions.
Addressing “politicians” in general, the scientists write: “On behalf of
