California Assemblymembers introduce bill phasing out gasoline-fueled small off-road engines

Green Car Congress

AB 1346 would require new sales of SORE to be zero-emission by 2024 or whenever the California Air Resources Board (CARB) determines is feasible, whichever is later. Today, operating the best-selling gas-powered commercial leaf blower for one hour emits air pollutants comparable to driving a 2017 Toyota Camry from Los Angeles to Denver.

New model projects total amount of global urban land could increase by up to a factor of 6 by 2100

Green Car Congress

A team from the University of Delaware and the University of Denver has created a new global simulation model to predict how urban land will change over the next 100 years under different social and economic conditions. The research team’s projections show that the amount of urban land on Earth by 2100 could range from about 1.1 million to 3.6

How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

To create a sustainable environment, we need to contain air pollution. SaaS platforms, such as Project Canary of Denver, help energy companies track, measure, and score the impact of methane and other volatile organic compounds on the environment across the energy supply chain. Deforestation is contributing to climate change.

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Quantitative use of this indicator ratio is subject to three major uncertainties: (1) the split between NO x -limited and NO x -saturated conditions may shift in space and time, (2) the ratio of the vertically integrated column may not represent the near-surface environment, and (3) satellite products contain errors.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities.
