Super efficient cookstoves from Somalia

Our atmosphere is like a bathtub, which we have been filling for decades with greenhouse gasses. Each ton of CO2e in the tub increases the global temperature and affects the climate.

In order to prevent our bathtub from spilling - which would mean reaching a +2°C temperature increase - 3 types of actions exist:

Solutions are different ways we can reduce, avoid and remove our emissions. They vary in terms of cost, level of maturity, potential to scale, and other factors. To make comparisons easier, Sweep groups solutions into categories such as Forests, Geoengineering or Buildings. Climate solutions are numerous: to learn more about what can be done, explore our catalog.

Solutions can be deployed in a large range of locations, from a micro-regions to entire sections of a continent. You might want to focus your contributions on specific areas to maximize local socioeconomic impacts or contribute where your activities are based.

Various international and regional standards rely on established methodologies, dedicated processes and third-party verifications to guarantee that a project delivers on its promises.

Capacity is the projected volume of tCO2e reduced or removed during the crediting period. This indicates the projected net impact of a project after adjusting for potential negative impacts and other externalities. This is key to assessing the current scale of a project and can give a quick estimate of what the considered volumes represent at the project scale.

Capacity does not reflect the available quantity of credits as some of them can already be sold.

Certified projects are eligible to generate carbon credits over a certain period of time. This crediting period gives a good estimate of the progress of a project.

Projects often have positive side effects beyond reducing, removing, or avoiding emissions. For example, projects might reduce waste, protect biodiversity, or support indigenous people. These co-benefits are modelled after the UN Sustainable Development Goals (UN SDGs).

Durability only applies to to removal solutions. It indicates for how long the carbon will be removed from the atmosphere - the longer this is the more desirable. For example, storing carbon as mineral underground is more durable than in a tree, making it a less risky and longer term solution.

Additionality reveals the impact of your financial support. It indicates what percentage of the global project budget is coming from contributions.

Barriers are the different hurdles a project might need to overcome. Barriers can give you a sense for the challenges a project faces, but also how it can add deeper value and create change. We differentiate five types of barriers: economic, social, institutional, technical and financial.
