The global commercial aviation sector contributes approximately 2.5% of anthropogenic carbon dioxide (CO2) emissions, but its complete climate impact—when accounting for non-CO2 radiative forcing agents…
Ocean carbon absorption quietly moderates global warming. Seawater takes up roughly one-quarter of the carbon dioxide released by human activity each year, slowing its accumulation in the atmosphere.
A carbon budget shows how much carbon dioxide humanity can still release while keeping global warming below a chosen temperature limit.
Shipping emissions regulations by country play a crucial role in reducing the environmental impact of maritime transportation.
High speed rail emissions per passenger-mile are dramatically lower than flying or driving alone for comparable trips — studies consistently show high-speed rail emitting a fraction of aviation’s per-
When comparing emissions between hydrogen cars and traditional gasoline vehicles, it is essential to consider the full lifecycle of both technologies.
In today’s world, the impact of public transport on the environment is a critical issue that cannot be ignored.
Well to wheel emissions measure every greenhouse gas released to get a vehicle moving one mile — from pumping crude oil or generating electricity, all the way through combustion or battery.
SUV emissions run meaningfully higher than smaller vehicles for a simple reason: weight and aerodynamic drag both scale up with vehicle size, and SUVs have grown enough as a share of new vehicle sales
The type of vehicle also plays a significant role in determining CO2 emissions per mile.
