Carbon credit allowances play a crucial role in combating climate change through a cap-and-trade system that limits greenhouse gas emissions and permits trading of emission units. Entities like the California Air Resources Board, Regional Greenhouse Gas Initiative, and Quebec’s Cap-and-Trade System issue these allowances, supporting a significant carbon market in North America. Alongside, voluntary standards such as Verra and the Gold Standard certify projects for carbon credits, contributing to global efforts against climate change. Understanding and participating in these systems allows businesses and individuals to actively contribute to reducing carbon footprints and advancing towards a more sustainable future.
