Covers low‑emission mobility options, public transit, and electric vehicles.
Electric vehicles (EVs) produce zero tailpipe emissions, but their full environmental impact depends on manufacturing, electricity generation, and disposal. Life-cycle assessments show that EVs…
Bus Rapid Transit (BRT) and Light Rail Transit (LRT) are two leading surface mass transit options for cities seeking to reduce congestion and emissions.…
Sustainable aviation fuel (SAF) offers a promising pathway to reduce aviation's carbon footprint, with lifecycle emission reductions of up to 80% compared to conventional…
Reducing vehicle size is a proven, low-cost strategy to cut greenhouse gas emissions, air pollution, and resource consumption. Larger vehicles consume more energy and…
Transit-Oriented Development (TOD) is a planning approach that creates compact, mixed-use communities around transit stations to reduce car dependency and promote sustainable urban growth.…
Complete Streets is a design and policy approach that ensures streets are safe and accessible for all users, not just cars. Evidence shows it…
High-speed rail offers a lower-carbon alternative to short-haul air travel on dense corridors, with proven success in Europe and Asia. However, its high upfront…
Induced demand is the well-documented phenomenon where expanding road capacity leads to increased traffic volumes, often negating expected congestion relief. This analysis examines the…
Shipping, the backbone of global trade, accounts for about 2-3% of global greenhouse gas emissions. A combination of energy efficiency, alternative fuels, and operational…
Electric cars and public transport are two key strategies for reducing transport emissions. Public transport generally offers greater efficiency and co-benefits in dense urban…
