Reflective surfaces (climate engineering) Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface). The IPCC described this method as "whitening ...
Greenhouse gas emissions are one of the environmental impacts of electricity generation. Measurement of life-cycle greenhouse gas emissions involves calculating the global warming potential (GWP) of energy sources through life-cycle assessment. These are usually sources of only electrical energy but sometimes sources of heat are evaluated. [1]
Project Sunroof was created by Google engineer Carl Elkin as a 20% time project. While initially launching only in the cities of Boston, San Francisco, and Fresno, [3] the project now displays solar potential for 43 million homes in the US. [4] Google has previously invested in projects with solar energy provider, SolarCity.
Individual action on climate change. A demonstrator taking action through climate activism at the People's Climate March (2017) in Washington, D.C. Individual action on climate change is about personal choices that everyone can make to reduce the greenhouse gas emissions of their lifestyles. Such personal choices are related to the way people ...
Red dots: Before the 2015 Paris Agreement, the world was on a trajectory for global warming of 3.5°C. [1] Global net zero emissions describe the state where emissions of greenhouse gases due to human activities and removals of these gases are in balance over a given period. It is often called simply net zero. [2]
Carbon accounting. Depiction of carbon accounting using the WRI-Greenhouse Gas Protocol classification of emissions into three categories: Scope 1, 2, and 3. Additional downstream Scope 3 sources are shown on WRI’s website. [1][2] Carbon accounting (or greenhouse gas accounting) is a framework of methods to measure and track how much ...
The purpose of putting a price on a tonne of emitted CO 2 is to aid policymakers or other legislators in evaluating whether a policy designed to curb climate change is justified. The social cost of carbon is a calculation focused on taking corrective measures on climate change which can be deemed a form of market failure. [2]
The steps taken by the St. Louis Public Library result in a smaller carbon footprint and set a positive example for sustainable practices in the community. The total equivalent CO2 saved annually by these improvements is 817,734 pounds, which has the following comparisons: 931,964 Miles driven by an average passenger vehicle
