Carbon offsets alone won’t make flying climate-friendly

Grist

So as the aviation industry has gradually climbed aboard global pledges to get rid of carbon emissions, it has mostly promised to make up for its damage elsewhere — through offsets that might involve planting trees, restoring wetlands, or paying people to preserve ecosystems that otherwise would have been razed. Others warm it.

Planned UK spaceports could add significantly to emissions of climate-warming gases

Envirotec Magazine

The black carbon emitted by rocket launches has a climate warming impact of up to 1,500 times stronger than CO2 per unit of mass, new research shows. Although other particulate matter such as alumina is thought to cool the atmosphere, research into rocket launch emissions is inconclusive. air pollution each year.

Measuring NOx in combustion

Envirotec Magazine

The chemiluminescence reaction of ozone and nitric oxide causes the oxidation of nitric oxide (NO) to nitrogen dioxide (NO2) which generates photons that are measured using a photomultiplier tube. Typically, at Signal Group, the flows of ozone and sample are set in a ratio of 10:1. Ozonator design. Advantages of a vacuum CLD.

Carbon emissions are shrinking the stratosphere

AGreenLiving

Carbon emissions have caused the stratosphere to shrink by 400 meters since the 1980s, according to a new study published in the journal Environmental Research Letters. It is home to the ozone layer , which protects the Earth from harmful UV rays. The ozone layer has recovered since 1989, when CFCs were banned.

US, China commit to phase down climate-warming HFCs from refrigerators and air conditioners – but what will replace them this time?

Renewable Energy World

CFCs were destroying the ozone layer high in the Earth’s atmosphere, which is essential for protecting life from the Sun’s harmful ultraviolet radiation. How HFCs keep rooms and food cool. But when they break down, they create chlorine that reacts with the protective ozone, letting dangerous radiation through to the Earth’s surface.

Tech Startup Sustainability Guide: Running An Eco-Friendly Business

Green Business Bureau

One study found that the daily employee commute is responsible for 98% of an employee’s work-related carbon footprint. Servers in data centers need a cool environment, which demands energy. Also, although computers need a cool environment to run, make sure to not keep rooms too cold, which would waste unnecessary power.
